Description

[0002] Chemical wastewater is a mixture of various wastewaters discharged in chemical production, including process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water, etc. If these wastewaters are discharged without treatment, they will cause different properties and degrees of pollution in the water body, which will cause great harm to the environment.

[0003] Filtration is one of the important steps in treating chemical waste liquid. Some of the existing chemical waste liquid contains not only waste residue but also grease or foam. The viscosity of the waste liquid is relatively high. During filtration, the viscous grease mixed with the waste residue blocks the holes of the filter and is difficult to clean. The wastewater flow rate in the filtration equipment will become slower and slower after long-term use, thereby affecting the efficiency of chemical waste liquid treatment. Moreover, if the filter in the filtration equipment relies entirely on manual processing, it will not only be time-consuming and labor-intensive, but also require the filtration equipment to be stopped and the filter in the filtration equipment to be disassembled during the cleaning process, delaying the progress of chemical waste liquid filtration.
