摘　　要：在大东湖生态水网构建工程中,由于所引长江水不满足东湖Ⅲ类水质目标的要求,需在引水口对引水水质进行处理。选取东湖武钢引水口沉砂池为取样点,在对比分析沉砂池进口和出口原水主要指标及其分布特点的基础上,针对主要污染物TP和TN,对絮凝剂和助凝剂种类、最佳投药量、搅拌速度、泥沙絮凝沉淀时间、不同反应条件进行了实验研究。根据实验结果,确定了最佳絮凝剂、助凝剂和水处理实施方案。In the construction process of Donghu Lake Ecological Water Network Project, due to the quality of water diverted from Yangtze River can not meet the Class III water quality requirement of Donghu Lake, the diverted water should be treated at the entrance of water diversion canal. Selecting Wugang sediment settling basin at water diversion entrance as sampling poing case, we analyze the main water quality indexes and distribution Characteristics of water at entrance and outlet of the sediment settling basin, and conducted an experimental study on selection of flocculation agent and coagulant aid, optimization amount, stirring velocity, sediment flocculation time, different reaction condition aiming at the main pollutants of TP and TN,. According to the experimental results, the optimized flocculation agent, coagulant aid and water treatment scheme are determined.
