Fast sewage purification device for chemical engineering

Abstract

The invention discloses a rapid purification sewage device for chemical industry, comprising a purification device body and an activated carbon adsorption tank. The top of the purification device body is symmetrically provided with two water inlets, and the top of the water inlet passes through a first branch pipe and a high-pressure water pump. Communication, the inside of the filter cartridge is provided with a medicine outlet pipe, the bottom of the filter cartridge is conventionally connected to the motor through a transmission shaft, and a suction pump is provided on one side of the bottom of the purification device body, and the suction pump is connected with the water pipe through the water pipe. The second shunt pipe is communicated with a plurality of activated carbon adsorption tanks arranged inside the filter barrel. In the present invention, the setting of the high-pressure water pump can effectively improve the water inlet speed of the sewage, and the filter cartridge can make the rapidly injected sewage carry out solid-liquid centrifugal separation under the action of the motor, thereby effectively improving the efficiency of sediment removal in the sewage, and the separated The precipitation can be discharged through the precipitation outlet in time, preventing the clogging of the filter cartridge.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a fast sewage purification device for chemical industry. Background technique [0002] Chemical wastewater refers to the wastewater produced in the process of producing products in chemical plants, such as the oily wastewater produced in the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank farms, air separation and air compressor stations, etc. After biochemical treatment, it can generally meet the national secondary discharge standard. Due to the shortage of water resources, the water that meets the discharge standard needs to be further treated to meet the requirements of industrial water replenishment and reused. [0003] Chemical sewage usually contains a large amount of fixed substances. The traditional sewage purification device takes a long time, has low purification efficiency, and cannot effectively separate the solid ...

AI Technical Summary

Problems solved by technology

[0003] Chemical sewage usually contains a large amount of fixed substances. The traditional sewage purification device takes a long time, the purification efficiency is low, and it cannot effectively separate the solid and liquid in the sewage. With the increase of sediment, it is easy to cause the filter to be blocked. On the one hand, when water with a large flow rate hits the filter membrane, it is easy to cause impact damage to the filter membrane
