摘要
通过对金泽水库及其上游来水的水质水量监测,分析金泽水库及上游来水水质特征与变化规律,认为:水质类别均值为Ⅲ类~Ⅳ类,极值为Ⅳ类;影响金泽水库水质的主要特征因子有石油类、粪大肠菌群、阴离子表面活性剂(ABS)、化学需氧量、氟化物、铁、高锰酸盐指数、五日生化需氧量、锑这9项;东太湖水质水量、支流流向及水质、污染物通量、降雨与太浦河泵闸调度是影响干流水质的主要因素。提出改善金泽水库上游来水水质的建议,将降水量超过50 mm与关闸作为锑预警指标,泵闸联动,保障金泽水库供水安全。
By monitoring water quality and quantity of incoming water from Jinze Reservoir and its upstream,the characteristics and variation rules are analyzed.It is concluded that average value of water quality is levelⅢ~Ⅳ,and the exfreme value is levelⅣ.There are 9 main characterization factors that affect water quality of Jinze Reservoir,petroleum,fecal coliform,anionic surfactant(ABS),chemical oxygen demand,fluoride,iron,permanganate index,five-day biochemical oxygen demand(BOD5)and antimony.Water quality and quantity of East Taihu Lake,tributary flow and water quality,pollutant flux,rainfall and pump-gate dispatching of Taipu River are the main factors affecting water quality of the main stream.In the paper,some measures for the improvement of incoming water quality of Jinze Reservoir and its upstream,such as taking precipitation over 50 mm and pump closure as antimony early warning indicators,pump&sluice gate operation,to make sure water supply safety of Jinze Reservoir.
