Description

Technical Field

[0001] The present invention relates to the technical field of chemical wastewater treatment, in particular to a chemical wastewater treatment device for chemical production. Background Art

[0002] Chemical wastewater refers to wastewater produced during the production process of chemical plants, such as oily wastewater from the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank farms, air separation and air compression stations, etc. After biochemical treatment, it can generally meet the national secondary emission standards. Due to the shortage of water resources, water that meets the emission standards needs to be further treated in depth to meet the recycling requirements of industrial water replenishment. Since the impurities in the water are mainly suspended particles and fine fibers, mechanical filtration principles and microporous filtration technology are used to remove impurities. However, in environments where the wastewater contains a high content of viscous media, wastewater treatment equipment has difficulty filtering. At the same time, viscous impurities will stick to the filter surface, greatly reducing the efficiency of wastewater treatment and causing the working efficiency of the wastewater treatment equipment to decline. Large particles of impurities will be stuck to the sewage outlet by the viscous impurities, causing the sewage outlet to be blocked, thereby reducing the working efficiency of the wastewater treatment equipment.

[0003] Chinese patent CN117049625A, authorized and announced on November 14, 2023, discloses a chemical wastewater treatment device, which includes a wastewater treatment barrel, a lifting cylinder is vertically arranged in the middle position inside the wastewater treatment barrel, a plurality of lower through holes are arranged at equal distances along the circumferential direction at the bottom of the lifting cylinder, a plurality of upper through holes are arranged on the outside of the top of the lifting cylinder, an injection part is arranged at the bottom of the lifting cylinder, and the wastewater treatment barrel and the lifting cylinder are jointly provided with an aeration mixing part, which has multiple sewage mixing effects, effectively improving the diffusion efficiency and fusion uniformity of the purification agent in the sewage, thereby increasing the sewage purification effect. In the above application document, the centrifugal filter used is more difficult to clean in an environment where the content of viscous medium in the wastewater is high. The viscous medium will stick to the surface of the filter, thereby affecting the treatment efficiency of the wastewater treatment device. The device discharges sewage through a circular groove outlet. The accumulation of large particles and viscous impurities will cause the outlet to be blocked, affecting the efficiency of the wastewater treatment device and making manual cleaning difficult in the later stage.
