分别采用聚合氯化铝和聚合硫酸铝铁对化纤综合废水进行了絮凝反应对比实验,并对优选的聚合氯化铝的应用条件进行了研究.其最佳絮凝反应条件为:控制酸析反应的pH在2.20左右,絮凝反应前调节原水pH至5,絮凝剂最佳投加量为3‰,助凝剂选用阳离子型PAM,最佳投加量为3 ppm.絮凝反应使废水色度和COD分别下降67%和38%.

The coagulant comparison reaction experiment of polyaluminium chloride and polymeric aluminum ferric sulfate was studied in the treatment of chemical fiber wastewater as flocculants. Application conditions of advanced polyaluminium was selected through comparative analysis. The optimal reaction conditions of polyaluminium were determined： the pH of acidolysis was controlled at 2.20 and before flocculation the pH of wastewater was adjusted to 5, the optimal dose of polyaluminium was 3%o, the cationic PAM was selected as coagulant aid and its op...
