摘要
采用聚合氯化铝(PAC)与有机高分子絮凝剂复合投加,对污水厂的曝气沉砂池出水进行强化预处理,研究其对浊度、COD的去除效果,确定最佳投药量,并对混凝所产生的污泥进行厌氧消化性能的研究.
Enhanced primary treatment is carried out to treat the sewage of aerated grit chamber in wastewater treatment plant by joint dosages of polymeric aluminium chloride (PAC) with organic polymer flocculant. The removals of turbidity and COD are investigated,and the optimum dosage is found out,then the feasibility of anaerobic digestion for coagulated sludge is studied.
