[0002] As we all know, chemical wastewater refers to wastewater generated during the production process of chemical plants, such as oily wastewater from the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank area, air separation and air compressor station, etc. After biochemical treatment, it can generally meet the national secondary emission standards. Due to the shortage of water resources, the water that meets the emission standards needs to be further treated in depth to meet the requirements of industrial water replenishment. Since the impurities in the water are mainly suspended particles and fine fibers, the impurities are removed by using the principle of mechanical filtration and microporous filtration technology.

[0003] According to a chemical wastewater treatment device disclosed in application number 202020260808.4, it includes a device body, a cover body is provided on the upper outer surface of the device body, a water inlet is provided on the upper outer surface of the cover body, an observation window is provided on the front outer surface of the device body, a water outlet is provided on one side of the device body, a motor is provided at the center of the lower outer surface of the device body, a sewage outlet is provided on one side of the motor, a column is provided at the center of the lower inner surface of the device body, a micro-rotating shaft is provided around the lower outer surface of the column, scrapers are provided on the outer surfaces of both sides of the micro-rotating shaft, and baffles are provided on the outer surfaces of both sides of the column. The chemical wastewater treatment device described in the utility model can quickly precipitate the chemical wastewater inside the device, with high precipitation efficiency, and can also better separate the bottom precipitation and the precipitated wastewater, with good practical effect.
