混凝剂聚合氯化铝与硫酸铝在水处理中的实验研究

通过实验,对比聚合氯化铝与硫酸铝两种混凝剂在相同条件下的混凝效果,认为聚合氯化铝耗药量少,最佳投药量为15mg/l时,浑浊度为2.2NTU,只需硫酸铝的1/3就可达到最佳混凝效果,沉淀效果比硫酸铝好,特别适用于pH低和浑浊度较高的水源水。

Experimental Research on Polyaluminium Chloride and Aluminium Sulphate as Coagulant Applying in Wastewater Treatment

Through experiment, we compared the coagulation effect of polyaluminium chloride and aluminium sulphate at the same condition. We concluded that polyaluminium chloride is better, because we need less quantities of the this coagulant, and can get the same coagulation effect. When the quantity, of polyaoluminiurn chloride is 1.5mg/l and the turbidity of water is 2.2NTU, we only need the quantity of polyaluminium chloride as 1/3 of aluminium sulphate. The polyaluminium chloride is better on applying in low value of pH and high turbidity of wastewater.
