Abstract
The utility model discloses a coating circulating water purification treatment system, include: the system comprises a circulating water tank, a first reaction tank, a second reaction tank, a sedimentation tank, a paint slag biochemical unit, a paint slag collecting tank and a filter press; the circulating water tank is sequentially connected with the input ends of the first reaction tank, the second reaction tank and the sedimentation tank, and the first output end of the sedimentation tank is connected with the circulating water tank; and a second output end of the sedimentation tank is sequentially connected with the paint slag biochemical unit, the paint slag collecting tank and the input end of the filter press, and the output end of the filter press is connected with the circulating water tank. The utility model discloses a to the transformation that spray booth itself hydrologic cycle purified and increase new purification unit equipment, effectively solved the emission problem of spraying waste water, can also reduce solid waste volume 70% -80%, thoroughly solved the high-priced expense problem when handling high concentration organic waste water and hazardous waste.
Description
Technical Field
The utility model relates to a sewage treatment device technical field, more specifically the coating circulating water purification treatment system that says so relates to.
Background
The coating is an important link in the modern product manufacturing process, the rust resistance and the corrosion resistance of the product can be obviously improved through the coating, and meanwhile, the coating can play a role in decoration, so that the product has extremely good luster and distinctness of image and brings beautiful visual perception to people, thereby becoming one of important aspects of the overall quality guarantee of the product.
However, with the rapid development of the coating industry, the three major problems of environmental protection are more and more severe. Firstly, the equipment maintenance outage rate is high, the time for equipment maintenance and cleaning of a slagging pool is too long, the cleaning labor consumption is large, and the cleaned waste water and solid waste amount are large; secondly, the amount of high-concentration organic wastewater is large, the COD treatment time is too long, and the treatment cost is too high; thirdly, the water content of the paint slag is too high, the produced amount is large, the treatment cost is high, and the environmental protection standard is high. The treatment of coating wastewater becomes a major problem in the current sewage treatment project and is to be solved urgently.
