Site search about the enterprise subscribers call-center partners specialists Additional services Home / About the company / Vodokanal yesterday, today, tomorrow / Velizhan water treatment plant Velizhan water treatment plant In the Soviet years, when the industry of the Sverdlovsk region was at the peak of its development, the reason for the emergency construction of the Velizhan water treatment facilities was the release of arsenic recorded in Tura, due to which, for almost a day in the 70s, it was necessary to stop the supply of water to the city from the only that time of the Head water treatment plant. It was then that both the localities and the capital seriously thought that Tyumen needed an alternative backup source of water supply. A whole range of geological exploration work was carried out in record time. The results were disappointing - the nearest suitable water deposits were found thirty kilometers from the city. Nevertheless, it was decided to build the station. According to the decree of the Council of Ministers of the USSR dated February 5, 1971, the capacity of the structures was supposed to be 70,600 cubic meters of water per day. Already in February, the breakdown of the pipelines began. Despite the lack of housing, frost and impassable roads, the construction of all production facilities was in full swing, water conduits were laid on the wells. And on November 5, 1971, the wells of the third cluster were launched to flush the constructed water pipelines. The Velizhan water treatment plant supplied the first water to the city in February 1972. As part of the structures of the Velizhansky water intake, an iron removal station of the Velizhansky water intake (VVOS) was designed and built: 1st stage - 1970-1971; II stage - 1975-1976 - We started from scratch. There was not even a treatment plant as such at that time, - recalls Galina Golubeva, who worked as the head of the chemical and bacteriological laboratory of the Velizhan water treatment plant from 1972 to 1997, - therefore, we supplied the first water, very few cubes, not purified. Over the past few years, a lot has changed for the better at the Velizhan water treatment plant. The global reconstruction of buildings was not without funding from the regional budget. The control room is now unrecognizable. They made repairs here and installed new modern equipment. Tatyana Pavlovna Kalugina has been working at facilities for 22 years, 20 of them as a shift supervisor. - A lot has changed since I came to work. Previously, we had equipment from the seventies in the control room, there was no talk of computers, - says the shift supervisor, - Now we are introducing automation. But new technologies do not frighten, as our interlocutor admits, earlier it was easier to work, because it is more familiar, but now it is more interesting. - Day after day we comprehend something new. Requirements for workers are increasing - it is necessary to replenish knowledge. The station is developing and now the main thing for us is to keep up with this development, - says Tatyana Pavlovna. When asked why she loves her work so much, Tatyana Pavlovna frankly answers: - We have our own little world here, without which we can no longer imagine life. At the moment, the Velizhan water treatment plant can purify and supply up to 120 thousand cubic meters of clean drinking water to the city every day. Alexander Grigoruk, head of the area for raising and purifying water at the Velizhansk Wastewater Treatment Plant, remembers when such figures were only a distant prospect: - In 1985, when I came to work, there were only 8 or 9 filters in operation. The rest were standing, a reboot or repair was required. But then there was no particular need for them, it was the heyday of the Metelevskaya water treatment plant. According to the project, the first stage was designed for 75 thousand cubic meters of water per day, but practice has shown that the technology that was incorporated in the project does not justify itself and the station cannot provide 75 thousand cubic meters of water to the corresponding SanPIN for iron. Over time, we learned how to cope with iron, introduced something ourselves, science suggested something. Based on the operating experience of the first stage, adjustments were made to the project of the second. As a result, instead of one of the filters, an aerator-degasser was installed. The second stage, consisting of 15 filters and aerator-degasser, was put into operation in 2007. The testing of modern technologies at the Velizhan water treatment plant is a continuous process. “For science, the doors at the Velizhan water treatment plant are always open,” adds Alexander Grigoruk, “and we are happy to try and try any proposal, if only there is a result. The introduction of an automated process control system did not bypass the Velizhansk water treatment plant. The first 15 wells were automated in 2010-2011. - We extract water from a depth of 50 to 70 meters, - says Evgeny Gennadievich Kalugin, head of the well maintenance and repair section, - from each of the wells we pump from 50 to 100 cubic meters per hour, depending on the flow rate of the well and the pump power. Since 2010, we have been using an automatic control system, that is, directly from the cleaning station, the dispatcher can control, turn on - turn off the well, see all its main parameters. Well pumps are used in several types, including those of our own production. In the Soviet years, when deep pumps were in short supply, the mechanical repair shop of the Velizhan water treatment plant set up its production and repair of pumps. This workshop is a special pride of Velizhan people. At one time in the Soviet Union there were only two factories producing this specific product, meanwhile the pumps were constantly breaking down and required repair. - The pumps were out of order and there was a need for their repair, over time we came to the point that we began to practically manufacture them, now we can prepare our own pump for each well, with its own capacity, supply, - says Vasily Ivanovich Nikityuk, head of repair and mechanical workshop of the Velizhan water treatment plant. In the filtration room of the water treatment plant, work is in full swing around the clock. Here you need to constantly monitor the process of water purification and, if necessary, when changing the modes of water supply to the city, take prompt measures. “We monitor the level in the filters so that the filter does not“ run away ”or, on the contrary, does not“ fall ”on the sand,” says Olga Komar, a filter operator. After the filtering hall, the already purified water is sent to the clean water tanks. Its supply to the city is provided by a powerful pumping station of the second lift. the premises were repaired, and the pumping units and valves were replaced with more modern samples, and variable frequency drives were installed. They are needed in order to regulate the water supply to the city not with stop valves, but with the speed of the pump engine - this is more efficient in terms of energy consumption and eliminates the risk of water hammer. It will also allow regulating the water supply to the city in automatic mode, according to the set pressure parameters at the control points. In 2009, the drainage system of the American firm "Triton" was tested and put into operation on filter No. 13, after the research it was decided to fill this filter with a new loading for Tyumen - flask (specially burnt rock). In 2011, the reconstruction of the bacteriological laboratory of the buildings was completed. 2011 became literally historic for the laboratory of the Velizhan Water Treatment Plant, it was repaired, re-equipped and passed the necessary accreditation. According to the general development plan of the city, Tyumen may become a million-plus city by 2040. In this connection, the need for water can be about 450 thousand cubic meters per day. Water intake from the Tura River, by environmental legislation, is limited to 200 thousand cubic meters, therefore, the Velizhan water treatment plant is a promising source of water supply for Tyumen. Preparations for this are already underway. Technical characteristics of Velizhan water treatment facilities Проектная производительность – 128 тысяч кубических метров питьевой воды в сутки. Источник воды – Велижанские и Тавдинские месторождения Западно-Сибирского артезианского бассейна. Глубина скважин – от 50 до 70 метров. Производительность скважин – 50-100 кубических метров воды. Количество скважин – 93 (расположены на четырех лицензионных кустах) Первая очередь водоочистных сооружений эксплуатируется с января 1972 года, вторая с 2007 года. Количество фильтров: первая очередь – 16, вторая очередь – 15 и аэратор-дегазатор. Проектная скорость фильтрации – 4 метра в час. Высота слоя загрузки фильтров – около 2-х метров. Процесс очистки воды от захода на станцию до попадания в резервуары чистой воды занимает около 1-го часа. Расстояние от Велижанской ВОС до г. Тюмени – 30 километров. Подача чистой питьевой воды в город осуществляется по двум водоводам d=1000. Подача воды в час максимального водопотребления составляет 3800 – 4200 м3/час, при напоре 56 – 62 м.вод.ст., возможно увеличении подачи до 4900 м3/час при напоре 70-74 м.вод.ст. Подача воды в час минимального водопотребления составляет 1400 – 1600 м3/час, при напоре 30 – 32 м.вод.ст. Wells supplying water to the Velizhansk water treatment plant are located within a radius of 30 kilometers from them. A total of 93 wells serviced by Tyumen Vodokanal: 1st section - 13 pieces. 2nd section - 20 pieces. 3rd section - 23 pieces. 4th section - 37 pieces. (Chugunaevskaya line - 18 pieces.) (Krysovskaya branch - 19 pieces.) Due to the continuously increasing pollution of surface waters, groundwater is practically the only source of household and drinking water supply for the population. Therefore, their protection from pollution and depletion, rational use are of strategic importance. Around each well of the Velizhan water treatment facilities, the first belt of the sanitary protection zone is maintained and fenced within a radius of 30 m. In this zone, all types of construction are prohibited that are not directly related to the operation of the water intake and water supply facilities, the residence of people (including those working on the water supply system), as well as the use of pesticides and fertilizers. Taking into account the possibility of water pollution through the heads and heads, all wells are located in standard pavilions, the heads are hermetically sealed, and the wells are cemented. In 2009, as part of the investment program of Tyumen Vodokanal LLC, at the Velizhansk water treatment plant, 15 wells were upgraded with the replacement of pumping equipment for more efficient ones and the installation of automated process control systems for wells. During the modernization, Wilo borehole pumps were used: EMU K 85-4 + NU501-2 / 30 (11 pcs.), EMU K 84-5 + NU501-2 / 30 (2 pcs.), EMU K 85-5 + NU611- 2/37 (1 pc.), EMU K 84-4 + NU60-2 / 22 (1 pc.). The economic effect from the introduction of these pumps in 2010 amounted to 468,113 thousand kW / h. In 2011, downhole pumping units ETsV-10-63-110 were replaced with more energy-efficient pumping units SAER at 17 more wells of the Velizhan water treatment facilities. The economic effect from the introduction of these pumps in 2011 amounted to 463.7 thousand kW / h or 1080.4 thousand rubles. in monetary terms. The wells operate around the clock, water from them enters the deferrization station. Water preparation (clarification, deferrization) is carried out at treatment facilities using aeration followed by filtration. The water supplied for cleaning is distributed on 16 high-speed filters of the first stage and 15 filters of the second stage. The filters are loaded with special fraction quartz sand and flask. In November 2009, the reconstruction of the fast filter No. 13 was completed at the Velizhan water treatment plant, during which the drainage system and filtering material were replaced. A new TRITON drainage system of the American company Johnson was used on the filter and shut-off valves manufactured by Danfoss with AUMA electric drives were installed. The filter is loaded with a single-layer loading ODM-2F fraction 0.8-2mm. ODM-2F is a filter material with sorption properties based on natural mineral raw materials from deposits of the Sverdlovsk region - opal - cristobalite rock, belonging to natural zeolite tuffs with a basic substance content of 85 - 95%. Regeneration of the filtering capacity of the load in all filters of the water treatment plant is carried out by flushing with a reverse flow of water, which is taken from the reservoir of clean water. Treated water is supplied to 2 pure water tanks with a capacity of 6,000 m3 each and to a tank with a capacity of 10,000 m3, where it is mixed and disinfected with chlorine before being fed to the city's distribution network. The supply of clean drinking water to the city is provided by a pumping station of the second rise. To ensure the operation of the station, in 2011, work was completed to replace the equipment of the RP-6kV. The new 6 kV switchgear is equipped with modern high-voltage cells of the SIMOSEC type for a voltage of 7.2 kV with vacuum switches and digital multifunctional relays SIPROTEC from Siemens. The SIPROTEC 7SJ62 relay is used as a protection, monitoring and control device for inputs to switchgear-6 kV, sectional switch, lines to electric motors, variable frequency converters for modulating regulation, pressure increase in the urban network. The construction of the new RP-6kV was carried out in parallel with the installation of new pumping units D-2000-100 at the pumping station of the second lift with the installation of a VFD for smooth regulation of water supply to the city network. At the pumping station of the second lift, five pumping units are in operation for supplying water, two more are used for technological needs. As part of the reconstruction, carried out at the expense of the regional budget, four pumping units were replaced with modern models. Currently, the station uses pumps D2000-100-UHL4 (JSC UETM-UGM, Sysert, Sverdlovsk region). The pumping units of the second lift station have the following technical characteristics: pumping unit No. 1 D2000-100 productivity 2000 m3 / h, head - 100 m.w.st. pumping unit No. 2 D2000-100 productivity 2000 m3 / h, head - 100 m.w. pumping unit No. 3 D2000-100 productivity 2000 m3 / h, head - 100 mWC (installation) pumping unit No. 4 D2000-100 productivity 2000 m3 / h, head - 100 mWC (installation) pumping unit No. 5 D3200-75, capacity 3000 m3 / h, head - 75 m.w. The pressure in the city water supply network, as well as the regulation of the water supply regime from the Velizhansk water treatment plant is carried out on the basis of data received from the control points in real time to the central dispatching office of the Tyumen Vodokanal company. Throughout its history, the Velizhan water treatment plant has been and remains a platform for the introduction of modern technologies. The implementation of technological and organizational measures aimed at the development and modernization of water supply facilities, the work is carried out in several directions: increasing the reliability and efficiency of work; restoration of operational properties, throughput of pipelines; восстановление эксплуатационных свойств и производительности скважин до утвержденных запасов; экономия электрической энергии на отдельных скважинах до 20%; оперативное управление работой скважин; обеспечение надежности работы насосной станции 2-го подъема, снижение энерго- и эксплуатационных затрат; оперативное управление режимами работы насосов и резервуарами чистой воды. Общая характеристика подземных вод артезианского бассейна Западно-Сибирский артезианский бассейн является одним из крупнейших аккумуляторов подземных вод России. Для хозяйственно-питьевого водоснабжения почти повсеместно используются воды верхнего (первого) гидрогеологического комплекса (воды третичных отложений), эксплуатационные запасы которого чрезвычайно велики. Особенности гидрогеологии, рельефа, климата, гидрографии, многолетней мерзлоты на территории региона позволяют выделить две группы бассейнов стока подземных вод: северную и южную. Северная группа бассейнов исследована недостаточно, в том числе северные районы Средне-Обского бассейна. В формировании подземных вод региона определяющую роль играют болотные воды. Отсутствие кислорода в водах торфяных залежей и высокие концентрации углекислоты приводят к нарушению устойчивости фосфорсодержащих минералов и насыщению их фосфатами. Характерной особенностью подземной воды нашего региона является наличие растворенных газов, в частности диоксида углерода и сероводорода. Под влиянием избыточного увлажнения происходит интенсивное разложение растительных остатков, и образование органических веществ кислотного характера, что приводит к энергичному выветриванию минеральной части отложений. Поэтому воды региона преимущественно гидрокарбонатно-кальцевые, значительно обогащенные гумусом и железом. Наличие в воде гумусовых соединений не только непосредственно влияет на ее качество, обуславливая повышенную цветность, но и приводит к активизации процессов комплексообразования с некоторыми нормируемыми элементами (так, например, железо-фосфатные комплексы). Железо содержится в форме минеральных соединений (железистые соли железа двухвалентного и трехвалентного) или в форме органических соединений гуминовых кислот, в комплексе с органическими веществами, обычно кислыми солями. Thus, the underground waters of the Tyumen region are complex multicomponent systems, including a whole complex of inorganic and organic substances and dissolved gases. print version © 2016 LLC Tyumen Vodokanal.
