Absorption cleaning of ventilation emissions
Authors: Barysheva Olga , Osipova Lilia , Osipov Eduard 
Published: August 2020

Abstract
Various methods are used to clean industrial ventilation emissions: mechanical, electrical, absorption, thermal, catalytic. Absorption methods are economically justified when the concentration of impurities in the gas stream is more than 1 %, which are present in the vent emissions of technological industries. The main element of the absorption cleaning systems is the absorber, the design and technological parameters of which determine the entire layout of the gas cleaning system. For the proper selection and calculation of the absorption treatment scheme, it is necessary to know the production technology, equipment, where emissions are generated in excess of the norms of maximum permissible concentration, as well as the properties of process flows. Using the universal modeling program ChemCad allows reducing the time for calculating the thermodynamic and physicochemical properties of flows, increase their accuracy and eliminate errors when choosing treatment equipment at industrial enterprises. The results of the study were proposed when designing a scheme for the absorption cleaning of ventilation emissions in the production technology of paint and varnish products or the technology of production of drywall.
Numerical simulation of a z-shaped ventilation elbow and reduction of its resistance
Authors: Ziganshin Arslan , Solodova Eugenia , Logachev Konstantin 
Published: August 2020

Abstract
The paper presents the results of a numerical study of the flow in a Z-shaped elbow. Dependencies are found for the local drag coefficient of such a unit, the coupling effect coefficient, the lengths of the influence zones and the outlines of the vortex zones on the distance between the individual components in this unit. The dependence for the LDC, as well as the coupling effect coefficient, agrees quite well with the known experimental data, which indicates the validity of the numerical model. Using the found outlines of the vortex zones, numerical models of energy-efficient profiled Z-shaped elbows were developed and investigated. Graphical dependence of the LDC of such a duct unit on the distance between the single elbows is developed. The resulting dependence shows a decrease in resistance by 70 % compared with the standard design. For a whole ventilation system, it will lead to energy savings spent on the drive of the fans, and therefore to reduce operating costs. Using of a large number of such energy-efficient duct elements will allow replacing the fan with a less powerful one, which will lead to reduction in capital costs for construction.
Numerical and experimental study of the device for the control of the ventilating airflow
Authors: Safiullin Fanis , Broyda Vladimir 
Published: August 2020

Abstract
Ventilation systems often operate under changing conditions, which leads to a deviation of the actual air flow from the calculated one. When the gravitational pressure increases, they remove more air than the calculated amount, which leads to increased heat expenditure on heating the air, which compensates for exhaust during the cold period of the year. To maintain a constant calculated flow rate and reduce heat losses during the cold season, especially for natural exhaust systems, it is rational to use direct-acting ventilation air flow regulators.
The aerodynamic characteristics of such a device for regulating the flow of ventilation air are obtained numerically and experimentally: the coefficient of local resistance ζ and the parameter k, which characterizes the aerodynamic force acting on the movable element of the regulator.
The accuracy of experimental study is proved. Comparison of the results of numerical and experimental research showed their good correspondence, which confirms the suitability of the data obtained for the design and calculation of air flow regulators of the considered type.
Chromium-containing wastewater treatment by means of using galvanocoagulators
Authors: Busarev Andrey , Abitov Runar , Selyugin Aleksandr 
Published: August 2020

Abstract
In this study, a galvanocoagulator was used for the treatment of chromium-containing wastewater. Its principle of operation is based on the use of processes for reducing Cr(VI) ions to the Cr(III) state using a galvanic pair “copper-iron” without applying an external electric field. In this case, the reduction of hexavalent chromium ions to trivalent occurs due to the oxidation of iron ions, which, when dissolved, pass into the solution. To speed up the process of iron dissolution, compressed air is supplied to the galvanocoagulator. The conversion of Cr(VI) and Cr(III) into insoluble compounds is performed by adding alkali solutions. The resulting suspension is removed from the water by settling and filtering methods. As a result of research, the possibility of effective treatment of chromium-containing wastewater using the method of galvanocoagulation was established; the technological parameters of the galvanocoagulator were determined. The hydraulic size of the suspension formed after processing of chromium-containing effluents in a galvanocoagulator is determined, which allows designing treatment facilities for the removal of heavy metal hydroxides by settling.
Oil-containing wastewater treatment by means of using coarse-grained coalescing filtering materials
Authors: Urmitova Naziya , Abitov Runar , Nizamova Aida 
Published: August 2020

Abstract
A large amount of oil-containing wastewater is generated in the oil industry. Before injection into the layer, oil and mechanical impurities must be removed from the oil-containing wastewater to the specified limits for injection into the oil formation. During the purification of oil-containing waste water, the method of settling on structures of various designs is widely used. To intensify the sedimentation processes of oil-containing wastewater, pre-treatment methods are used before sedimentation in treatment plants. One of the most effective is the process of coalescence on structures with the use of granular coalescing nozzles. Granulated coalescing materials based on polymer materials and expanded clay have been developed to intensify the process of oil-containing wastewater purification. Based on the experiments, it was found that the best materials for coalescence purposes are coarse-grained coalescing hydrophobic loads for wastewater filtration at high speeds, which operate in self-regeneration mode. This increases the depth of oil-containing wastewater purification and reduces the duration of the settling process by two or more times.

Abstract
The urgency of biogenic elements removal is caused by ever-increasing degree of eutrophication of surface water, which increases the mass of phytoplankton, water turbidity, oxygen concentration in the upper water layers and reduces in thickness. To remove biogenic elements from wastewater, a method based on the use of bioreagents – chemical compounds of trace elements based on biologically active copolymers – is successfully implemented.
This article presents the results of a survey of existing facilities of a biological wastewater treatment plant in a small locality. The survey revealed low efficiency of processes at the stage of biological purification, primarily with regard to the speed of biochemical processes, namely, the time-limited ability of dephosphotation, and as a result, a small withdrawal of total phosphorus at the stage of biological purification directly by active sludge microorganisms. In order to intensify the work of biological wastewater treatment facilities, an experiment was conducted on the use of bioreactor in real operation at these treatment facilities.

Authors: Akhmerova Guzel , Zalyalova Alina , Mukhametshina Raliya 
Published: August 2020

Abstract
The issues of influence of soil moisture, heat insulation type and heat carrier temperature on heat losses of district heat supply networks pipelines are considered. Calculations were carried out to change the efficiency of insulation of polyurethane foam and polymineral foam for four different modes of operation of district heat supply networks pipelines with gradual moistening of soil from 0 to 48% with channel-free lying; insulation is not wetted. The reasons and consequences of different temperature levels in district heating networks in Russia and Western Europe are considered. The calculated distribution temperatures in the central heating system pipeline were 75.85/49.85°C. The results show that the thermal losses of the pre-insulated pipelines increase many times depending on the soil moistening. In addition, calculations showed that in absolutely dry soil heat loss of pipelines of heat networks laid channel-free for all considered modes is less than calculated. But absolutely dry soil is a condition characteristic of deserts rather than the Middle Volga region.

Published: August 2020

Abstract
The analysis of scientific literature, technical solutions and inventions in the field of polymer composite materials for temporary gas pipeline compaction is carried out. It was revealed that for sealing the pipeline, polymer compositions based on rigid polyurethane foams, or compositions that swell in the cavity of the gas pipeline with the formation of a gel-like plug, can be used. A mandatory requirement is the ability to remove the sealing plug from the insulated cavity of the gas pipeline after the completion of repair work.
The analysis also showed that there are few studies in the field of creating polymer composite materials for temporary sealing of gas pipelines. The development of compositions that meet all the requirements is of practical interest for the gas industry.

Abstract
The article analyzes the results of the implementation of numerical methods of architectural form finding in educational design in the second year of study developed at the design department of KSUAE as part of the undergraduate course. The original method of form finding is a combination of tabular methods for setting the geometric parameters of architectural forms in Revit Architecture and visual programming tools such Grasshopper and Dynamo. This experiment in the field of “design of the architectural environment” (DAS) with extensive use of BIM-technologies and digital modeling in the educational process, has been conducted for more than 3 years and gives positive results, the main of which is the intensification of the educational process and the variability of complex geometric shapes based on the use of advanced numerical methods. According to this approach, the entire course consists of 4 stages, which students consistently perform during the second year of study, work on one architectural topic, which covers four coursework projects: “Composite design of an architectural form” (structural “skeleton”), “Design of an architectural facade” (“architectural skin”), “Design of the internal space “(interior), “Design of the external space” (exterior). They represent four parts of one general topic, each of which should demonstrate the influence of different subsystems of the structure on the overall volumetric and planning solution. In the process of work at each stage (course project), there is a constant resolution of the contradictions that arise during the design process between the various subsystems by regenerating the general architectural model as part of the Revit Architecture parametric modeling program, which plays an important role in the formation of students’ professional skills.

Authors: Marina Smolova , Daria Smolova 
Published: August 2020

Abstract
Over the millennia, the human mind underwent numerous alterations, each time accumulating more and more information in itself. In human consciousness, associations are one of the key elements in the development of abstract intelligence and thinking. The process of memorization involves the creation of associations that can be found in any process of human activity, especially in architecture, art and design. Associations assist in rational evaluation of architecture and design as a source of new ideas and images. They become a fabric of innovative methods in discovering human-nature connectiveness, which is being expressed on our urban environment, communities and people. The significance of associations in architectural education derives from students’ participation in the formation of urban fabric and thus it is central to analyze associative mechanisms and typologies to evaluate trends and prosperity of cities. The paper will include stages of associative thinking, types and their reflection on students’ works.

The impact of the implementation of an innovative project on the effects arising in the internal and external environment
Authors: Zaynullina Dilyara 
Published: August 2020

Abstract
The purpose of this research is to determine the effects arising in the internal and external environment of an innovative project, which is supposed to help make a decision regarding the implementation of the project. For that we have selected about 200 innovative projects of various types of economic activity, such as: services, manufacturing and mining sectors. All projects are implemented in the Republic of Tatarstan. For each of the projects we considered the following types of effects: economic and social for the external environment and technological and environmental for the internal environment. To identify the interconnection between internal and external effects from innovative projects, we used the method of correlation and regression analysis. Implemented innovative projects in the service sector, leading to significant internal technological effect, have a significant impact on the external economic effect and do not affect the external social effect. Manufacturing projects are characterized by a significant impact of internal technological effect on external economic and social effects, while the internal ecological effect has the greatest impact on both external effects. Innovative projects in the mining industry are characterized by a significant impact of internal ecological and technological effects on external economic and social effects.

Authors: Maksimchukand Olga , Pershina Tatyana 
Published: August 2020

Abstract
The concept of sustainable city development based on a balance of environmental, economic and socio-cultural factors in modern conditions is often replaced by the concept of city competitiveness as autonomous socio-economic systems. The imbalances in the city development and their inequality in terms of the comfort of population living are becoming ever more acute at the junction of the contradictions of these concepts. Comfortability of living in the city is the main competitive advantage of every city, thanks to which it has all the conditions for high-quality reproduction of the most important wealth-human resources, attraction and effective involvement of labor resources in the economic life of the city. It explains the relevance of the study, which proposed a theoretical and methodological justification of the city competitiveness in terms of assessment the comfort of living in it. This approach is original, has a high degree of reliability, the ability to verify the forecast of the competitiveness of a modern city. The results of testing prove the feasibility of its use in the development and scientific justification of strategies for sustainable development of the cities.
