TAILIEUCHUNG - Báo cáo "A study of waste water impacts of main factories on water quality of To Lich river, Ha Noi "

Waste water from industrial sites amounts to one third of total waste water discharged into To Lich river, and may have serious effects on the river water quality. With the total amount waste water of factories (Hanoi beer alcohol and beverage joint stock corporation (HABECO), Trang An JSC and Thuong Dinh industrial park) of 45,000 m3/day, these factories accounts for more than a half of total industrial waste water released into To Lich river. The analytic results of water samples taken from To Lich river show that the parameters of DO, COD, BOD5, TSS, NH4+, NO2- and coliform. | VNU Journal of Science Earth Sciences 26 2010 174-178 A study of waste water impacts of main factories on water quality of To Lich river Ha Noi Tran Van Quy Tran Van Son Faculty of Environmental Sciences Hanoi University of Science VNU 334 Nguyen Trai Hanoi Vietnam Received 9 September 2010 received in revised form 11 October 2010 Abstract. Waste water from industrial sites amounts to one third of total waste water discharged into To Lich river and may have serious effects on the river water quality. With the total amount waste water of factories Hanoi beer alcohol and beverage joint stock corporation HABECO Trang An JSC and Thuong Dinh industrial park of 45 000 m3 day these factories accounts for more than a half of total industrial waste water released into To Lich river. The analytic results of water samples taken from To Lich river show that the parameters of DO COD BOD5 TSS NH4 NO2- and coliform exceed the Vietnamese Standards QCVN 08 2008 column B2 . However the concentrations of Fe and heavy metals Zn Cd Cr Cu Mn are lower than the Vietnamese Standards QCVN 08 2008 column B2 except the concentration of ion Pb especially in the area from Thuong Dinh Industrial Park to the last segment of the river. The analytic results of waste water from the main factories HABECO Trang An JSC and Thuong Dinh industrial park Hanoi Soap Joint Stock Company HASO Saovang Joint-stock Rubber Company SRC Tool Joint-stock Company TJC show that the parameters of TSS BOD5 COD total of nitrogen total of phosphorus are higher than the Vietnamese standards for Industrial waste water QCVN 24 2009 BTNMT column B . In particular all waste water parameters of Trang An JSC are lower than the Vietnamese Standard for Industrial waste water QCVN 24 2009 BTNMT column B because the factory has an effective waste water treatment system. The heavy metals parameters of waste water from all factories are lower than QCVN 24 2009 BTNMT. Estimated loads of contaminants in waste water from the .
