【摘要】 针对以印染废水为主的工业一生活混合型城市污水 ,以CODcr、色度、SS为出水水质指标 ,对混凝剂Y2 80的水处理性能进行初步研究 ,并与硫酸铝、氯化铁、聚铁和聚铝进行对比。试验表明 ,投药量相同时 ,混凝剂Y2 80处理的出水水质较好 ;出水水质相近时 ,混凝剂Y2 80的投药量最少。综合经济效益和环境效益 ,确定混凝剂Y2 80的最佳固体投加量为 1 2 0mg/L ,此时 ,CODcr去除率为 67.78% ,色度去除率为 75% ,SS去除率为 68.1 6 % ,每吨废水处理费用为 0 .2 1元 ,而其它药剂则为 0 .30元更多还原

【Abstract】 A comparison was made with several kinds of Coagulant to treat the printing and dyeing waste water with COD cr , color, SS as the cheeking parameters. The test results proved that Y280 is better than other coagulants such as Al 2 (SO 4 ) 3 , FeCl 3 , PFeCl and PAC in dosage and treated water quality. The optimized dosage of Y280 was 120mg/L with 67.78% removal rate of COD cr , 75% of color and 68.16% of SS, and the cost was 0.21 yuan/m 3 , while the cost of other coagulants were 0.30 yuan/m 3 .更多还原
