Abstrakt:

In this experiment, the combination of physic-chemical and biological methods was applied. Firstly, degreasing wastewater and painting wastewater were pretreated by chemicals respectively. And the removal rate of CODCris more than 50% and about 65% respectively. After pretreatment,the effluents together with electrophoresis wastewater were treated by the coagulation-flotation and SBR process. And the removal rate of CODCrreached more than 80%, which achieved primary standards of "Integrated Wastewater Discharge Standard"(GB8978-1996). After the separated pre-treatment, the consuming amount of the chemicals had obviously lowered than the conventional mixing treatment, as well as the sludge. Most importantly, this process ensures good quality of water. So it is feasible economically and technically to use separated pretreatment, air flotation and SBR to treat automotive painting wastewater.
