Painting production-exhaust gas pollution:
The exhaust gas comes from the exhaust gas of the pretreatment, spray paint room, flow room, and drying furnace. The use of paint without organic solvents or its low content is an effective method to solve the organic solution. Exhaust gas comes from pre-treatment, spray paint room, flow room, and drying furnace. The use of paint without organic solvents or its low content is an effective method to solve organic solvents, minimize the amount of organic solvents, and reduce the amount of organic solvents. Waste gas treatment, The exhaust gas containing high concentration organic solvents is concentrated and discharged to the atmosphere after dilution. The low concentration and high wind volume exhaust gas discharged from the spray paint room, the use of activated carbon dioxide adsorption method, and the use of activated carbon fiber bee wheel method to treat organic exhaust gas.
Second, coating production-wastewater pollution:
Wastewater comes from the degreasing, phosphating, passivation wastewater produced by the pre-coating treatment, the wastewater containing electrophoresis, the spray room of the waterborne paint, and the wastewater generated by the cleaning, and the paint paint paint room. Regular discharge of wastewater. Generally, all wastewater is concentrated in the basement and treated according to the type of sewage. For acid-base wastewater neutralization, precipitation, filtration, discharge; For wastewater containing 6 valence Chromium, electrolytic and chemical reduction methods are used. Treatment of spray paint waste water, addition of fine coagulants, paint slag is automatically discharged, treated waste water, continue recycling, paint slag burned or treated with other industrial waste.
Third, coating production-waste residue pollution: mainly the treatment of sediments produced by wastewater, generally can be used to strip filter press water quality, to the special waste residue storage site.
Fourth, coating production-noise pollution: noise comes from the fan and transportation device, so in the production line must be selected to meet the noise requirements of the fan and transportation device, the painting workshop is best set up inside the sound absorption material.
