絮凝法处理含油废水的试验研究

Experimental study on treating oil-containing waste water by flocculation reaction

针对含油废水的特性 ,我们用絮凝法对含油废水进行了初步处理 ,试验结果表明 :含油废水中加入1 0 0mg/L聚合AlCl3絮凝处理后 ,油去除率可达 86 4% ,CODcr去除率可达 42 2 % ,可成为生物处理法的预处理工艺。

Based on the characteristics of oily effluents,the flocculation reaction was chosen for the effluent pre-treatment.The experimental results show:when 100mg/L AlCl 3 was plunged,then oil removal was 86 4%;CODcr removal was 42 2% after reaction.This treatment can become the pre-treatment for biological treatment.
