Deal with wastewater, electrophoresis wastewater and spray paint the watewater are mainly produced in the coating process of automobile. The main pollutants are resin surface-activeagent phosphate, etc. Serious pollution can be caused by these pollutants. The compositions of coating wastewater are complicated and discharging has no orderliness, so water quality has great changes. Proved by experiment after disposed by neutralization reactor and flotation treatment, the coating wastewater goes into hydrolysis-acidolysised andmicrobe-containing treatment. Its every index canreach the first class discharge standard of GB8978-1996 of "comprehensive discharge standard ofsewage" through monitoring.
