Condensing lens is a lens used as an auxiliary lens in indirect instruments to examines the fundus. This lens is used with binocular indirect ophthalmoscope and slit-lamp biomicroscope to reach a stereopsis image of fundus. Optical principle of condensing lens is to make the eye in myopic condition, so it can producesa real, aerial, inverted and reversed image. This lens was placed between the instruments and the eye of the patient which located closer to patient’s eye. Optimalized position of the lens can produce a good fundus image.
Condensing lens have so many power of dioptre that each power produces different magnification and field of view. High powered lenses produces wider field of view than low powered ones. High powered lens can also used in patient with small dilated pupil and shorter distance of examination. Low powered lenses offer more magnification.
Fundus examination with binocular indirect ophthalmoscope and slit-lamp biomicroscope have purpose to produces stereopsis image because of the binocularity system. These two instruments have each advantages and disadvantages. The advantages of binocular indirect ophthalmoscope are a portable instrument, relatively can be used in uncooperative patient and it can be used with scleral indentation to reach more peripheral view of the fundus. Meanwhile slit-lamp biomicroscope has the advantages to offer more magnification and flexible illumination system. With higher powered lens use in biomicroscope, it also give advantages in shorter distance of examination and wider field of view.

Анализ современных подходов к расчету очистных сооружений свидетельствует о том, что расчетный расход воздуха определяют в соответствии с потребностью биологического процесса в кислороде на окисление органических соединений, нитрификацию и денитрификацию. Адаптированы международные термины и аббревиатуры к российским аналогам во взаимосвязи с теорией массопереноса кислорода, а также зарубежные руководства по проектированию сооружений для аэрации сточных вод. Поясняется различие между натурными (измеряемыми экспериментально) и расчетными (определяемыми для проекта) параметрами OUR и AOR, SOTR и SOR. Балансовое равенство между OTR и AOR является оптимальным и экономичным проектным решением. Отмечено, что использование актуализированных международных терминов и аббревиатур в тендерных и конкурсных процедурах (при проектировании и поставке) упростит их проведение и обеспечит взаимопонимание сторон.

Рассмотрены современные решения, предлагаемые для реконструкции малых очистных сооружений, в составе которых имеются биофильтры. Пик проектирования и строительства биофильтров пришелся на 1960 1970е годы. В настоящее время биологические фильтры зачастую служат для доочистки сточных вод. Предлагается снова их использовать в качестве основных очистных сооружений. Данные сооружения, как правило, конструктивно представляют собой железобетонные емкости, поэтому целесообразно разработать новые технологические схемы с учетом использования существующих сооружений. Рассмотрены три технологические схемы с различной комбинацией зон нитрификации и денитрификации. Приведены графические результаты санитарнотехнических анализов по ряду показателей, на основании которых показана достаточная эффективность очистки для сброса очищенной воды в водоемы рыбохозяйственного значения. Предложен метод расчета биофильтров для конкретных загрузочных материалов. Сделан вывод о том, что высота сооружения зависит не только от необходимой степени очистки, параметров поступающей воды, но и от вида и размера загрузочного материла. Предложенные технологические схемы позволят шире использовать биофильтры как при реконструкции существующих, так и при проектировании новых очистных сооружений.The advanced solutions proposed for the reconstruction of small wastewater treatment facilities that contain biofilters are considered. The peakpoint of designing and constructing biofilters occurred in the 1960 1970s. At present biological filters are often used for wastewater treatment. It is proposed to use them again as the basic treatment facilities. These structures, as a rule, are structurally reinforced concrete tanks so it is advisable to develop new process flow schemes taking into account the use of existing structures. Three process flow schemes with different combinations of nitrification and denitrification zones are considered. Graphic results of sanitary and technical analyses of a number of indicators are presented on the basis of which sufficient purification efficiency is shown that allows discharging effluents into fishery water bodies. A method for calculating biofilters for specific media materials is proposed. It is concluded that the height of the structure depends not only on the required level of purification, the parameters of the incoming water but also on the type and size of the media material. The proposed process flow schemes will provide for the wider use of biofilters both in the reconstruction of existing and in the design of new treatment facilities.
