The low concentration and large air volume exhaust gas discharged from the paint chamber is treated with activated carbon adsorption method, and the activated carbon fiber bee wheel method is also used to treat organic waste gas.

Neutralization, precipitation, filtration and discharge of acid-alkali wastewater; Waste water containing 6 - valent chromium was treated by electrolysis and chemical reduction. For the spray booth waste water, add fine coagulant treatment, paint residue is discharged automatically, treated waste water, continue to recycle use, paint residue burn off or with other industrial waste disposal.
