摘要
通过絮凝剂聚合氯化铝(PAC)与以盐生藻为原料制成的多糖类生物助凝剂(ABCA)复合投加,进行烧杯试验,研究了PAC与ABCA的最佳投加量。并通过与助凝剂PAM,HCA的比较,分析了ABCA的助凝性能。结果表明,PAC与ABCA的最佳投加量分别为16 mg/kg、0.30 mg/kg,与PAM,HCA相比,ABCA的性能更好,浊度去除率达到98%以上,矾花大小适中,且沉降速度快。
Through the combination of polyaluminium chloride （PAC） and original polysaccharide biocoagulant aid（ABCA） , which was made from algae in salt pond, and by the means of jar test, their optimal dosages were studied. Comparing with the different coagulant aid（ PAM, HCA） , the performance of ABCA was analyzed in the water treatment. The results showed that the optimal dosages of PAC and ABCA were 16 mg/kg and O. 30 mg/kg respectively. And ABCA has better performances with the removal rate of turbidity more than 98% , the suitable floe and the quick sedimentation as well.
