【摘要】 针对常规铝盐、铁盐去除洗浴废水中阴离子洗涤剂 (LAS)效果不理想的状况 ,采用高碱化度钙型聚合铝硅混凝剂 (CPASC)进行了试验研究 ,同时与聚合氯化铝 (PAC)作了比较。结果表明 ,该混凝剂对洗浴废水中COD、LAS、SS及浊度都有较高的去除率 ,特别对LAS、COD的去除率分别比PAC高 10 %和 8%以上。当投加量为 6 0mg/L时 ,出水各项指标均达到生活杂用水水质标准 (GJ2 5 .1 89)。更多还原

【Abstract】 A novel calcified polyaluminium silicate chloride (CPASC) flocculant with high basicity used in bathing wastewater reuse was investigated. The experimental results show that CPASC had high removal efficiency of COD, LAS, SS, and turbidity. The removal efficiency of LAS and COD with CPASC was higher 10% and 8% respectively than it did with PAC. The effluent can reach the national standards of wastewater reuse when the dosage of CPASC was 60 mg/L.更多还原
