摘　　要：针对一年中长江原水和黄浦江原水的水质情况,进行了两种原水几种水质指标的对比分析,混凝沉淀后两种原水氨氮和CODMn的达标情况对比,以及不同水温对于两大原水浊度、氨氮和CODMn混凝效果的影响。结果表明,黄浦江原水的浊度、氨氮和CODMn一般比长江原水高,pH比长江原水低,经过混凝沉淀处理后长江原水氨氮和CODMn的达标率比黄浦江原水高,两种原水的浊度、氨氮和CODMn的去除率随水温的升高有增大的趋势,若两种原水进行混合,为保证其处理后水质达标,则黄浦江和长江原水的配比最好不能超过2∶8。Based on the qualities of raw water from the Yangtze River and Huangpu River,comparative analysis of qualities of raw water from the two sources was conducted for several water quality indexes including ammonia nitrogen and CODMn after coagulating sedimentation and effects of temperature on coagulation of turbidity,ammonia nitrogen and CODMn.The results showed that turbidity,ammonia nitrogen and CODMn of the raw water from Huangpu River were generally higher than that from the Yangtze River,but pH of the former was lower than the latter.After coagulation treatment,the proportional rate reached discharge standard of ammonia nitrogen and CODMn of Yangtze raw water was higher than that from Huangpu River raw water.There was a tendency that the removal rates of turbidity,ammonia nitrogen and CODMn from the two sources increased with water temperature.If the raw waters from the two sources need to be mixed to treat,to ensure the treated water quality,mixture ratio of raw water from Huangpu River to that from Yangtze River should not be less than 2∶8.
