摘要
通过研究发现,单独采用氧化、调pH、絮凝以及吸附单元操作处理含甲醛废水,对废水的COD去除有一定效果,但药剂用量很大,采用氧化-调pH值-絮凝-吸附联串工艺,对废水COD的去除效果明显,药剂用量适中,是解决这类难度很大废水的预前处理的实用而有效的方法.
The research indicates that the treatment of HCHO waste water with oxydation,adjustment of pH,flocculation,or respectively adsorption has certain effect for reduction of COD of waste water,but the amount of consumed chemicals is very large.The treatment with operation of oxydation adjustment of pH flocculation adsorption has tangible result for reduction of COD of waste water,the amount of consmed chemicals is reduced.This method for pretreatment of waste water with great difficulty is practical and effective.
