Description

A flocculation and decontamination industrial sewage treatment device with self-cleaning function

technical field

The invention relates to the technical field of sewage treatment, in particular to a flocculation and decontamination type industrial sewage treatment device with self-cleaning function.

Background technique

Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in all walks of life, and its significance is very important. Sedimentation tanks are required in the process of sewage treatment. By adding flocculants to the sewage in the sedimentation tanks, the positive (negative) charges of the flocculants Groups and some particles or particles with negative (positive) charges in water that are difficult to separate are close to each other, lowering their potential, making them in an unstable state, and using their polymerization properties to make these particles concentrate, and through physical or chemical methods separate from.

After the flocculation is completed, it is necessary to use a mud scraper to clean the bottom of the sedimentation tank, but the mud scraper is often directly immersed in the sewage during the flocculation process, and the flocculated silt is attached to its surface, which is very inconvenient to clean and requires manual labor. Use a spray gun for cleaning, and the mud scraper on the side wall of the sedimentation tank is not cleaned cleanly, which requires a lot of labor.
