采用絮凝法对泡菜废水进行了絮凝烧杯试验,讨论了絮凝剂的选择、PAFC与PAM的不同用量、pH值以及温度对絮凝效果的影响,确定了絮凝剂处理废水的较佳絮凝条件。研究结果表明,PAFC用量90 mg/L,PAM用量60 mg/L,pH值为7,温度为35℃,在此条件下,泡菜废水处理率为:COD、NH3-N、TP去除率分别为83.9%、47%、92.5%。

This article used the flocculation method to carry on the flocculation beaker experiment to the sauerkraut wastewater and discussed the flocculant choice,the different dosage of PAFC and PAM,pH as well as the influence of temperature to the flocculation effect.This experiment has determined the suitable flocculation condition in processing wastewater with flocculant.The research results showed that the PAFC dosage 90 mg/L,PAM dosage 60 mg /L,pH 7 and 35℃,the removal raito of sauerkraut wastewater was COD 83.9%,NH3-N 47%,T P 92.5% under the optimal condition.
