摘要
从絮凝过程中污染物高低分子量组分、毒性、COD值的变化 ,研究了造纸制浆含氯漂白废水中絮凝对后续生化过程的协同效应 ,结果表明 ,化学沉淀处理可有效地去除废水中的高分子组分 ,降低废水的毒性 ,提高废水的生化性 .
The Cooperation of flocculation in the biochemical treatment of pulp CEH bleaching effluents was investigated through the change of high and low weight molecular composition 、toxicity and COD of effluents in the flocculation process, the result showed that in the chemical process the high weight molecular composition and toxicity can be effectively removed, which enhanced the following biological process.
