汽车涂装工艺过程中产生脱脂废水、磷化废水、电泳废水、喷漆废水(浓水)等四大类,统称为涂装废水.本文综述了各类废液和废水的来源、排放方式、污染物成分、浓度等,针对其特性,磷化废水采用间歇序批式物化预处理,除磷、除锌、除镍的效果达到99%.其出水与脱脂废水、电泳废水混合形成涂装废水,采用混凝气浮法进行预处理,去除有机物和悬浮物.其出水再与其他废水混合形成综合污水,利用两段式水解/好氧生物处理工艺,进一步去除高分子有机物,使各项污染指标达到国家排放标准.

Four type coating waste-water (referred to as the coating waste-water) such as the degreasing waste-water, phosphating waste-water, electrophoresis waste-water, spray paint waste-water were produced during automobile coating process. This paper summarizes the source, emissions, pollutant composition, and con-centration of all kinds of waste-liquid and waste-water. Phosphating waste-water was treated by sequencing batch physicochemical pretreatment according to its characteristics, the effect of phosphorus removal, zinc re-moval and nickel removal reached 99%. This effluent water was mixed with degreasing waste-water and elec-trophoresis waste-water to form a coating waste-water, the organics and suspended solids were removed by pre-treatment of mixed condensed gas. This effluent water was mixed with other waste-water to form a comprehensive sewage, by using two stage hydrolytic/aerobic biological treatment process, and further removal of organic poly-mer, so that the pollution indicators have reached the national emission standard.
