摘 要: 以深圳水库水为原水,选用聚合氯化铝(PAC)、硫酸铝和氯化铁作为气浮工艺的混凝剂进行分析处理,选择出适合深圳水库水的最理想混凝剂.试验结果表明:PAC、硫酸铝、氯化铁三者的最佳投药量分别为1.25、1.25、4mg/L;在各自的最佳投药量下,PAC对浊度、色度、CODMn的去除率都要优于硫酸铝、氯化铁,且使用PAC生成的浮渣量最少.因此选用PAC作为此气浮工艺的混凝剂进行后续研究. Using poly aluminum chloride(PAC),aluminum sulphate and ferric chloride as coagulant,the air flotation technique was applied to treat the reservoir water in Shenzhen City.By comparing the treating effect,we selected the best coagulant.The results show that the optimum dosage of PAC,aluminum sulphate and ferric chloride is 1.25 mg/L,1.25 mg/L and 4 mg/L respectively;under optimum dosage,the removal rate of PAC for turbidity,color and CODMn are better than aluminum sulphate and ferric chloride;the dosage of scum using PAC is the least.So PAC is used as the coagulant in air flotation process for further research.
