Ecological Systems and Devices Annotation << Back WATER SUPPLY AND CANALIZATION ON EXAMPLE VOLZHSKIY VOLGOGRAD REGION L.I. Sergienko, S.V. Parinov, S.P. Nikonorova The article describes the technology of preparation drink water in concern «Vodocanal» in town Volzhskiy Volgograd region. On water cleaning construction, consume coagulant gidroclor aluminium and flocculent «Praestol». Disinfection of water make at use of gipochlorit of sodium. In hamlet Krasnooktyaborskiy use disinfection with help ultraviolet emanation. By order of the «Vodokanal» group of scientists «Ecological chemistry» developed technology dewatering wastewater and rinsing water fi ltering stations precipitation. The offered technology is innovative. Its main difference is the use of highly effective drainage devices – unique fl occulent «Sibflok» fundamentally changes the conditions of dehydration. The technology allows: increase the load on sludge grounds by 7...12 times, depending on the moisture content of the sludge and the type of sites; reduction of turnover of sludge plots up to 1 year; dehydrate precipitation to a moisture content of 70...75 %; reduce the content of suspended solids in water and up to 0,05...0,3 g/l; signifi cantly reduce the emission of unpleasant odors; dewatering different by composition of precipitation with humidity from 96,0 to 99,8 %; receive dehydrated sediments that can be easily recycled in the form of composts, recultivants, etc.; ensure a year-round process of dehydration at temperatures below –20 °C. Keywords: drinking water; technology; disinfection; chloroform; coagulyant; floculyant. Contacts: E-mail: sergienko.l@bk.ru, E-mail: ser_p94@mail.ru, E-mail: nika.svetlova@bk.ru Pp. 50-55.
