Surface run-offs due to snow melting and rainfall gather dust, rubbish, oil-products and other pollutants and flow into nearest water basin that results in pollution of environment and surface water bodies. The article describes a package unit of waste water physical and chemical treatment for enterprises of railway and automobile transport. It also can be used for elevated track of railway sorting yard. The unit consists of degritter, holding tank, floater, granular and sorption filters. The unit was tested in laboratory and pilot conditions. It was put in a evaluation test with standardized test solution and real waste water.
Представлены результаты статистического анализа появления в воде водохранилищ централизованного водоснабжения города Симферополя Республики Крым органических загрязнений, определенных по показателю перманганатная окисляемость. Выявлена закономерность распределения содержания органических загрязнений и ее аналитическое описание для четырех источников централизованного водоснабжения. Получены модели распределения данного показателя для воды, прошедшей очистку на водопроводных очистных сооружениях Симферополя Республики Крым (в резервуаре чистой воды). Рассчитана эффективность работы двухступенчатой схемы очистки воды (горизонтальные отстойники-скорые фильтры) от органических загрязнений. Определена вероятность превышения нормативных значений перманганатной окисляемости для питьевой воды относительно норм Всемирной организации здоровья и требований на питьевую воду по данному показателю для Российской Федерации. Определена требуемая степень удаления органических загрязнений на водопроводных очистных сооружениях для обеспечения соответствия качества питьевой воды нормам Всемирной организации здоровья. The paper demonstrates statistical analysis results of biocontamination of Simferopol water reservoirs of centralized drinking water supply sources. The biocontamination results were obtained by permanganate oxidizability factor. The analysis revealed a consistent patt ern of biocontamination distribution and its analytical description for four sources of centralized water supply. The paper also introduces models of this factor distribution for water purifi ed in water-purifi cation plants of the city of Simferopol (in clean-water reservoirs). The eff ectiveness of two-step water purifi cation scheme (horizontalstrainer chamber-high-rate trickling fi lter) from biocontamination is calculated. The research demonstrates a probability of exceeding permanganate oxidizability normative values for drinking water according to WHO and EU standards and according to drinking water requirements for this indicator in the Russian Federation. The required degree of permanganate oxidizability disposal at water treatment plants which will make the quality of drinking water meet WHO and EU standards is also defi ned.
The paper considers railroad natural technogenic complexes (RNTC) and their engineering systems, such as: technogenic system, structure of natural-industrial railway system, natural-technogenic systems, borders of natural-industrial railway system and RNTC within the framework of a binary system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
