30m3 carbon steel fully automatic dissolved air flotation machine Integrated sewage treatment equipment

It is mainly composed of dissolved air pump, air water separator, flocculation chamber, air flotation contact chamber, separation chamber, sedimentation cone and collecting tank.

It is mainly used to remove suspended solids, grease and various colloidal substances in sewage. Factors are widely used in electroplating, chemical, paper making, oil refining and other industries.

Working principle

The dissolved air tank in the dissolved air flotation machine will produce dissolved air water, and then enter the sewage to be treated through the release pipe, so as to adhere to the impurity particles in the sewage, and make them form floating bodies, float on the water surface, and then form scum. Then remove the scum through the slag scraper. If the specific gravity is higher than that of water, it will be precipitated and discharged into the sludge tank to complete the sewage treatment.

Structural features

1. The requirements for flocculation are not very high, so the dosage of flocculant can be appropriately reduced.
2. The process and equipment structure are simple and easy to use and maintain;Its sewage purification effect is better than that of pressurized dissolved air flotation.
3. It is easy to adjust during operation, and the operation process is stable and reliable. It can avoid some common problems and save some trouble.
4. Aerate the water during air flotation, which has obvious effect on removing the surfactant and odor in the water. The colleague increases the dissolved oxygen in the water due to air limitation, providing favorable conditions for subsequent treatment;
5. It can eliminate sludge bulking.
