摘要
研究用壳聚糖、聚铝和助剂A复合制备出一种成本低、絮凝效果好、出水Al3+含量少的新型自来水处理絮凝剂,并确定其最佳配比(体积比)为:0.1%壳聚糖∶2%聚合氯化铝∶0.1%助剂A=1∶6∶5。与传统聚铝类絮凝剂相比,其出水浊度和Al3+含量分别下降了2.97%和10.7%,并且药剂成本下降6.25%,有明显的经济和环境效益。
This research on a new type Aeroflocs of running water treatment which uses chitosan, polymeric aluminum and assistant a compound preparation of a kind of lower cost, flocculation result being better, content of aluminium ion in outfall being less and decides its the best proportioning （volume ratio） as： chitosan O. 1% ： polyaluminium chloride 0. 1% assistant A = 1 ： 6 ： 5. As compare with traditional aeroflocs of polymetric aluminum type, the turbidity of ouffall and content of aluminium ion separately drop 2.97 percent and 10.7 percent, its cost of medicament decreases 6.25 percent and has cleat economic and environmental efficiency.
