摘要： 以滦河水为原水,进行不同药剂投加组合的中试优化运行研究,通过对不同预氧化投加量、药剂组合投加量下的原水处理效果进行分析,提出不同水质期滦河原水的药剂投加优化参数。在低温低浊期,没有预处理的情况下,聚氯化铝投加20 mg/L,三氯化铁投加15 mg/L;预臭氧0.8 mg/L条件下,聚氯化铝投加10 mg/L,三氯化铁投加10 mg/L,均可满足出水水质要求。在常温常浊期,预加氯0.5 mg/L条件下,聚氯化铝投加15 mg/L,三氯化铁投加15 mg/L,可以满足出水水质要求。在高温高藻期,预加氯1.2 mg/L条件下,聚氯化铝投加20 mg/L,三氯化铁投加15 mg/L,可以满足出水水质要求。

Abstract: A pilot study was conducted to optimize the operation of different combinations of chemical agents using the Luan River raw water. By analyzing the treatment effects under different pre-oxidation and chemical combination dosages,the optimization parameters of chemical agents for Luan River raw water in different water quality periods were proposed. The results show that during the low-temperature and low turbidity phase of the pilot test,a dosage of 20 mg/L PAC and 15 mg/L FeCl3 without pre-treatment,and a dosage of 0.8 mg/L preozonation,10 mg/L PAC and 10 mg/L FeCl3 can both meet the effluent quality requirements. During the normal temperature and turbidity period,a dosage of 0.5 mg/L prechlorination,15 mg/L PAC and 15 mg/L FeCl3 can meet the effluent quality requirements,and during the high temperature and high algae period,a dosage of 1.2 mg/L prechlorination,20 mg/L PAC and 15 mg/L FeCl3 can meet the effluent quality requirements.
