With the development of our country's economy, the population continues to grow, and more and more sewage is produced in the daily life of residents. If the sewage is not treated properly, it is likely to endanger the environment. At present, there are also equipments for treating this kind of sewage in the market. Generally, there are defects such as too complicated equipment, large space occupation, poor treatment effect, small treatment volume, and high cost.

Contents of the invention

Purpose of the invention: The purpose of this utility model is to provide a unified domestic sewage air flotation device in order to overcome the above-mentioned defects.

Technical solution: a unified domestic sewage air flotation device, including a tank body, a slag scraper, a stirring device, a water collection main pipe, a water collection branch pipe, and an aeration pipe. A water inlet pipe is provided on one side of the tank body. The other side of the tank is provided with a water outlet pipe, and the tank body is divided into a water inlet area, a reaction area, and a water outlet area through a partition from the water inlet pipe end to the water outlet pipe end, and a sewage outlet is provided at the bottom of the reaction area. There is a stirring device inside the water area, and an inclined partition is arranged in the reaction area, the bottom of the inclined partition is sealed with the bottom of the tank body, and there is a gap between the upper end and the top of the tank body, and the inclined partition divides the reaction area into an aeration area and the sedimentation area, the bottom of the aeration area is provided with an aeration pipe, and the inside of the tank is provided with a water collection main pipe, which is L-shaped. The horizontal part of the water collection main pipe is laid on the lower part of the sedimentation area, and the vertical part is arranged The horizontal part of the water main pipe is connected with a water-collecting branch pipe, and several water-collecting holes are arranged on the water-collecting branch pipe. A slag collecting tank is provided on the connection between the reaction area and the water outlet area, and the slag collecting tank is connected with the slag outlet. The slag machine is set on the top of the reaction zone.

A water flow regulator is provided at the water outlet of the water collection main pipe, and the water flow regulator includes a cone.

The aeration pipe is circular.

The angle of the inclined partition is 75°, and the distance between the inclined partition and the top of the tank is 1/3 of the height of the tank body. This arrangement is mainly for the water collection effect of the water collection branch pipe, because with the inclined partition, The water flow at the branch pipe is relatively steady.

Beneficial effects: the unified domestic sewage air flotation device integrates sewage treatment equipment, saves space, and the water quality after treatment is stable and low in cost. it is good.
