摘要
根据1986—2010年的水质监测数据,研究了黄浦江水系水质变化,并对影响水质的主要因素进行了探讨。结果表明,近25年的黄浦江水系水质变化基本可分为3个阶段:1986—1996年,上海市的畜牧业高速发展,生活污水量逐年上升,工业废水量较大而处理率低,水环境压力加大,水质持续恶化;1996—2002年,上游来水水质、生活污水量和畜牧业污染量均基本稳定,为水质改善创造必要条件,随着工业废水量的下降及废水处理能力的加强,水质持续改善;2002—2010年,上游来水水质在2002—2004年明显恶化,生活污水量再次进入快速上升期,加大了水环境改善的难度,水质改善趋势放缓并渐趋稳定。
Based on the monitoring datum from 1986 to 2010 the water quality characteristics of Huangpu River System and its cause were discussed.The result showed that trend of water quality change could divided into three phases.The water quality deteriorated continually in the first phase（1986—1996） because of the rapid development of stock raising,the rise of domestic sewage amount,the vast and untreated industrial wastewater.In the second phase（1996—2002）,the water quality improved continually with the reduce of industrial wastewater amount and the advancement of treatment of wastewater,and the stabilization of the water quality from upper reaches,the domestic sewage amount and livestock also made the improvement eventual.The water quality trended to be steady in the third phase（2002—2010）,because the water from upper reaches deteriorated fast and the domestic sewage amount ascended again.
