Description

A device for treating pollutants in industrial wastewater

Technical Field

The utility model relates to the technical field of sewage treatment, and more specifically to a pollutant treatment device in industrial wastewater.

Background Art

Sewage pretreatment is a pretreatment facility set up before sewage enters traditional sedimentation, biological and other treatments according to the water quality requirements of subsequent treatment processes. It is the throat of the sewage treatment plant. For centralized urban sewage treatment plants and decentralized sewage treatment plants within pollution sources, pretreatment mainly includes treatment facilities such as grilles, screens, grit chambers, and sand-water separators.

For some industrial wastewater, in addition to the above-mentioned general pretreatment, water quality and quantity adjustment and other special pretreatments are required before entering the centralized or decentralized sewage treatment plant, such as neutralization, debridement, pre-settling, pre-aeration, etc. If the pretreatment process does not meet the standards, it will cause too much screen residue, which will cause great loss to the subsequent treatment equipment. The existing patent is a solid pollutant pretreatment device for industrial wastewater. The patent authorization number is CN 210409806 U. Most of the solid pollutants are filtered through three layers of filtration to ensure that they do not affect the subsequent chemical filtration. Most of the solid pollutants can be separated by separation of the centrifuge. The last fish that slip through the net is filtered through the third layer of filter. The overall appearance is beautiful, compact, and has good treatment capacity.

However, in the patent authorization number CN 210409806 U, industrial wastewater flows into the device through the water inlet pipe 10, and large particles are filtered out through the first layer of filter screen, and small particles and wastewater flow into the centrifugal drum 8. Through the high-speed rotation of the centrifugal drum 8, the solid pollutants and liquid are separated by centrifugal force, so as to achieve the purpose of further removing solid pollutants. Part of the waste residue remains in the drum 8, and the other part of the waste residue is discharged through the sewage discharge barrel 2. Most of the waste residue is intercepted by the third layer of filter screen and discharged through the sewage discharge barrel 2. Since the waste residue in the centrifugal drum needs to be cleaned after it is full, it is necessary to stop the injection of sewage. Therefore, the sewage cannot be treated in the process of cleaning the waste residue, which affects the efficiency of sewage treatment. Therefore, we propose a pollutant treatment device in industrial wastewater to solve the above-mentioned problems.
