摘　　要：选用聚合氯化铝等絮凝剂以及电气石材料,进行了絮凝法处理模拟废水的试验研究。主要考察单一和组合情况下,不同絮凝剂的处理效果。结果表明,絮凝剂组合效果比较好。聚合氯化铝铁投药量选取5m L,聚丙烯酰胺投药量增加到2m L时,絮凝效果达到了最佳,浊度去除率达到了96.67%。聚合氯化铝铁投药量选取5m L,电气石投药量为6g(也即10g/L)时,废水浊度去除率达到了96.98%。可以认为聚合氯化铝铁与电气石组合去除废水是一种可行的方法,为今后开发廉价、高效、安全的絮凝剂去治理环境污染,提供相应的参考依据。The experimental study on the treatment of simulated wastewater was carried out by using flocculants such as PAC etc and tourmaline.The effects of different flocculants on the single and combined conditions were investigated.The results showed that the flocculant effect was good.When the dosage of PAFC was5mL and the dosage of PAM was increased to2mL,the flocculation effect was the best and the turbidity removal rate reached96.67%.When the dosage of PAFC was5mL and the dosage of tourmaline was6g(i.e.10g/L),the removal rate of turbidity was96.98%.It can be concluded that the combination of PAFC and tourmaline is a feasible method for the removal of wastewater,which provides a reference for the future development of cheap,efficient and safe flocculants to control environmental pollution.
