摘　　要：通过分析聚合氯化铝的投加混合方法对混凝气浮法处理废水效果影响得出结论:目前混凝气浮法废水处理实践问题是水力条件不合理,割裂混凝反应与气浮过程的关联性。用混凝气浮法处理废水,要考虑污染物颗粒亲水性与憎水性;要设计良好的水力条件;要保证混凝反应和气浮过程同步。特别是处理含亲水性污染物的废水,混凝剂只能采用泵后投药。混凝剂和溶气水应同步加入,混凝过程和气浮过程才能同步,才会有良好的气浮处理效果。处理洗涤污水不宜采用泵前投药、混合反应装置投药和混合反应漕。Conclusion through the study of the influence on the coagulation air flotation wastewater treatment effect by adding mixed method of Polymerization aluminum chloride:The current practice of wastewater treatment by coagulation air floatation is unreasonable hydraulic conditions,by the dividing relevance of the coagulation and floatation process.The wastewater is treated by coagulation and air floatation,Hydrophilic and hydrophobic of pollutants particles must be taken into account.Good hydraulic condition must be designed.Coagulation and floatation process must be ensured synchronization.Especially the treatment of wastewater containing hydrophilic pollutants,coagulant must be added after the pump.Only be added simultaneously of coagulation and dissolved air water,it's can be synchronous,and producing the good air flotation treatment effect.Something that is inappropriate for adding in front of the pump,mixed reaction device and the mixed reaction tank.
