淀山湖区(上海部分)水质污染源调查评价

THE RESEARCH AND EVALUATION ON WATER POLLUTION SOURCES OF DIANSHAN LAKE AREAS (SHANGAHI PART)

淀山湖是黄浦江的重要水源。被调查的水质污染源有工业、旅游、畜禽粪尿、人粪尿、生活污水、精养鱼塘、四种地表径流、稻田渗漏和航运。淀山湖区 1994年排放CODcr、BOD_5、总氮、总磷和石油等污染物分别为5113.3t、2093.4t、653.5t、139.2t和11.59t,总等标排放量为4154.2×10~6 m^3/年,其中主要污染源畜禽粪尿、生活污染和地表径流分别占46.76％、18.09％和12.25％,进入淀山湖的污染物等标排放量占总量的30.05 ％。研究结果为保护淀山湖水质提供了科学依据。

Dianshan Lake is an important water source of Huangpu River. Industries excursions, domestic animal and bird feces, human fecal sewage, living wastewater, breeding fish ponds, 4 surface runoff, paddy field permeation and shipping, as water pollution sources, were researched. In 1994 5113.3 t of CODcr, 2093.4 t of BOD5, 653.5 t of total N, 139.2 t of total P and 11.59 t of Oil were discharged into water bodies of Dianshan Lake Areas, total equivalent standard discharged amount (TESDA) of water pollutants was 4154.2 *106m3/Y. Domestic animal and bird feces, living pollution and surface runoff,as main pollution sources,took 46.76%, 18.09% and 12.25% of TESDA respectively, and discharged into Dianshan Lake pollutants took 30.05% of TESDA. The research results offered science basis for water quality protection of Dianshan Lake.
