1. Sprinkler wastewater
Organic waste gas spray tower is also known as waste gas treatment scrubber, acid mist scrubber, organic waste gas treatment scrubber, also known as acid mist purification tower, acid gas purification tower, acid mist absorption tower, exhaust gas purification tower and FRP acid mist purification tower, which can remove harmful gases in the air. The system uses a fan unit to suck the collected exhaust gas into the scrubber and flow through the filling layer, so that the exhaust gas is in full contact with the liquid medicine flowing on the surface of the filler, so as to adsorb the acidic or alkaline dirt contained in the exhaust gas.
The spray tower is a kind of equipment for waste gas treatment, which has a good deodorization and dust removal effect in industrial waste gas, but the circulating water of the spray tower will be smelly and dark after being used for a long time. Usually there are other wastewater in the customer's factory, and the amount of waste water in the scrubber is relatively small, and the wastewater from the spray tower contains fluoride, chloride, ammonia nitrogen, silica and other substances, and the customer hopes to be able to treat it to meet the standard reuse of tap water.
Therefore, the wastewater generated by the spray tower should be treated with paint mist coagulant, and the wastewater should be treated by flocculation and precipitation, and then the deodorant should be used to remove the odor of the circulating water, so that the discharged gas can be discharged up to the standard, and the wastewater can be clean and reused.
2. Painting wastewater
Most customers have a painting workshop, in the painting process of the painting workshop, generally through the water curtain (water curtain) device of the circulating water to absorb the spray paint mist, due to the accumulation of more and more paint, resulting in turbidity, deterioration and odor of circulating water.
It can also be treated by clean water, and the painted circulating water can also be further purified and reused for production, and the sewage in the spray booth does not need to be discharged and recycled for a long time.
However, due to the high cost of water exchange and biochemical treatment, the water volume of the plant is small, so it is difficult to accept. However, if it is not treated, the pollution problem in the water curtain painting wastewater has brought inconvenience to many coating enterprises, such as: water curtain adhesion, blocking the pipeline and wastewater affecting the working environment, the above mentioned two kinds of wastewater generated by the spray tower cleaning wastewater and painting circulating water, can achieve zero discharge of wastewater through physical means, and the physical way is suitable for spray tower cleaning wastewater and painting wastewater.
