Qingdao Qingtian Environmental Engineering Co., Ltd. is a comprehensive enterprise engaged in the production of sewage treatment equipment, sewage engineering design, and construction. The main products include: vortex concave air flotation machine, vortex concave aeration machine, dissolved air flotation machine, air flotation aeration machine, new dissolved air system, high-efficiency shallow air flotation machine, combined air flotation equipment, scraper, scraper suction machine, inclined plate oil separator, mechanical filter, automatic dissolution machine, integrated sewage equipment, etc. We use a dissolved air flotation machine to treat sewage, and each part needs to operate together. The flotation equipment mainly has four systems, each of which plays its own characteristics. Let's describe the different roles of the four systems of the flotation equipment:

1、 Agglomeration part: Adding chemicals to the sewage first can allow the liquid medicine and sewage to be thoroughly mixed by rotating the impeller of the sewage pump. The medication is supplied by the dosing equipment. The treated wastewater enters the air flotation tank and undergoes sufficient coagulation.

2、 Reflux water soluble gas release part: The effectiveness of the dissolved gas flotation machine mainly depends on the dissolved gas and release effect of the reflux water. This air flotation adopts high-efficiency and energy-saving gas dissolution and release equipment. Mix and dissolve the compressed air from the air compressor with the treated return water pressurized by the water pump in the dissolved air tank, forming dissolved water. The working pressure of the gas tank is generally 2-3.5kg/cm2.

3、 Air flotation section: The sewage that has been treated with chemical coagulation enters the air flotation tank, and the dissolved air in the dissolved air tank is depressurized by the dissolved air release device at the lower part of the inlet and outlet of the water pipe, releasing a large number of microbubbles from the air dissolved in the water. During the rising process, microbubbles encounter suspended solids that have already condensed in the sewage. The microbubbles attach to the suspended solids, causing them to quickly float up, so that all suspended solids treated in the sewage float on top. Then, they are scraped off by the upper scraper of the air flotation and discharged into the sludge tank, while the treated clean water at the bottom of the tank is discharged. 4、 Electrical control part: This equipment is equipped with an electrical control cabinet, and after debugging the device, it can reach unmanned operation status. The electric control cabinet controls the operation of the dissolved air pump, scraper, and air compressor.
