| 摘 要： | 采用"改性沸石粉+聚氯化铝铁"联用的强化混凝方法,对水中藻类和浊度的去除进行了研究。考察了改性沸石粉和聚氯化铝铁(PAFC)投加量、药剂投加方式、混凝沉淀时间、pH等因素对除藻去浊效果的影响,并对比分析了强化混凝与预氯化除藻的效果及对三氯甲烷的影响。结果表明,"改性沸石粉+聚氯化铝铁"联用强化混凝方法的除藻去浊效果良好,明显优于单独投加PAFC;将改性沸石粉先于PAFC投加,在适宜的试验条件下,浊度和藻总量的去除率可分别达到85.78%和90.07%;采用强化混凝方法替代预氯化方法除藻,不仅可以提高藻类的去除率,而且不产生预氯化副产物三氯甲烷等"三致"化合物。 |

| Abstract: | The removal of algae and turbidity from raw water by enhanced coagulation of the combination ofmodification zeolites and polyaluminum ferric chloridewas studied.The effects of the dosages of modification zeolites and polyaluminum ferric chloride,the dosing method,precipitation time,and the initial pH on the removal ratio of algae and turbidity were investigated.At the same time,the effects of the enhanced coagulation and the pre-chlorination on the algae removal were also studied.The experimental results in... |
