Abstract
The article gives results of the surveys water management systems, auto repair companies, bus compamies, taxis, fleets of trucks, production and technical enterprises. Studied technological processes of primary production: cleaning engines, flushing of radiators and parts of batteries, testing of fuel tanks, cleaning of parts and units, exterior washing and painting of motor vehicles. There were carried out field examinations of local industrial wastewater treatment facilities industrial wastewater and onsite construction runoff, the laboratory-production work to identify quantitative and qualitative indicators of the incoming and treated effluents, including petroleum products, suspended matter, salinity, synthetic surfactants, heavy metals etc. Proposed sustainable solutions for the improvement of the work of treatment facilities of rain sewage by mechanical and physical and chemical methods, including horizontal sand catchers, septic tanks – oil separator, a cascade of pressure filters with granular mineral over-loading and high-performance sorption materials, the effectiveness of treatment meets the requirements of water for its re-use for technical needs, and discharge to water bodies.
Highlights
IntroductionThe problem of disposal of industrial and rain wastewater of truck companies due to the continuous increase in the number of cars that consider as high toxic sources of pollution both air and water basins of Moscow city
Modern dynamics of the growth rate of the car amount leads to the need to develop organizational and technical solutions aimed at minimizing the negative impact of the functioning transport enterprises (TE) on the environment of the city
To achieve the modern requirements to the wastewater before discharge into the centralized Sewerage system, it seems advisable to collect and diversion of industrial runoff of TE to separate the Sewerage scheme and subsequent local cleaning each thread. It processes all the water drinking and technical water on the TE is used for household needs and showers, sanitary washing of floors in buildings and wash works to clean the territory, in garage, technological processes for the repair and maintenance of motor vehicles and feeding of circulating technical water supply systems and boilers [4,5,6,7]
Summary
The problem of disposal of industrial and rain wastewater of truck companies due to the continuous increase in the number of cars that consider as high toxic sources of pollution both air and water basins of Moscow city. Decrease of the capacity of the road network during peak times, as vehicles moving with low speed, a lot of maneuvering, the engines are stressed and, increases the amount of products of combustion of motor fuel and increased wear of the tread rubber tyres of cars, tire dust, which contains carcinogenic substances (Nnitrosamines) and benzopyrene, flushed by storm water;. Contaminants (more than 200 types, in particular, carbon monoxide (CO), oxides of nitrogen (NOx) and sulfur (SO2), polycyclic aromatic hydrocarbons (benzopyrene (С20Н12), hydrocarbons, halogen-containing, phenols, aldehydes, and ketones of aliphatic, alkylaromatic esters, heavy metals, sulfur-containing deposited substances, soot, etc.) received from vehicles in the atmospheric air, soil-and water Wu in the movement, storage, launching, cleaning, maintenance and repair, as well as disposing of the car and its elements
