Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model.

As shown in Figure 1, it is an embodiment one of a kind of sewage treatment equipment described in the utility model, including the first stirring tank 1, the second stirring tank 2, the sedimentation tank and the drainage tank 3, and the inside of the first stirring tank 1 is provided with Submersible mixer 4, the number of the sedimentation tanks is at least two, the first mixing tank 1, the second mixing tank 2, several sedimentation tanks and drainage tanks 3 are connected in sequence according to the process flow; the second mixing tank 2, several sedimentation tanks A sludge collection chamber 5 is provided at the bottom of the pond and the drainage pond 3 .

Specifically, the number of the sedimentation tanks is two, which are respectively the first sedimentation tank 6 and the second sedimentation tank 7; the first stirring tank 1, the second stirring tank 2, the first sedimentation tank 6, and the second sedimentation tank 7 and drainage pool 3 are connected in sequence according to the technological process.

During sewage treatment, the flocculant is added to the first mixing tank 1 through the powder dosing system that comes with the equipment, and under the action of the submersible mixer 4, the flocculant is fully mixed with the sewage; then the mixture flows in a self-flowing manner Enter the second stirring tank 2.
