摘　　要：本文以夏季长江水为试验原水,开展工艺适用性小试、中试试验,在当前原水水质条件下,探讨2种不同混凝工艺的水处理效果。试验结果表明,斜管沉淀工艺与脉冲澄清工艺应对引江水均可以达到良好的混凝沉淀效果,可为后一步过滤工艺减轻运行负荷。两种工艺整体除浊效果接近,脉冲澄清工艺对有机物去除效果更好,斜管沉淀工艺应对低浊度原水的适应性更强。同时混凝效果对控制出厂水残余铝有重要作用,控制混凝沉淀出水浊度0.5 NTU以下,可有效控制沉后水残余铝0.15 mg/L以下,保证出厂水残余铝符合国家标准要求。This article took the summer Yangtze River water as the experimental raw water,conducted small-scale and pilot tests on process applicability,and explored the water treatment effects of two different coagulation processes under the current raw water quality conditions.The experimental results showed that both the inclined tube sedimentation process and the pulse clarification process could achieve good coagulation sedimentation effluent effect for the river diversion water,which could reduce the operating load for the subsequent filtration process.The overall turbidity removal effect of the two processes was similar,while the pulse clarification process had better removal effect on organic matter.The inclined tube sedimentation process had stronger adaptability to low turbidity raw water.At the same time,the coagulation effect played an important role in controlling the residual aluminum in the finished water.Controlling the turbidity of the coagulated and precipitated water below 0.5 NTU can effectively control the residual aluminum in the settled water below 0.15 mg/L,ensuring that the residual aluminum in the finished water meets the requirements of national standards.
