Background technique

At present, with people's increasing emphasis on environmental protection, sewage treatment has become an issue of increasing concern to the government and citizens. In the prior art, a three-stage treatment method of precipitation, reaction and filtration is generally adopted in sequence for wastewater treatment. This treatment method can guarantee the water quality effect after treatment to a certain extent. However, because the three-stage treatment method generally requires the use of sedimentation tanks, reaction tanks and sand filters, and the use of pipelines to connect the three. In this way, the following problems are likely to arise;

1. Because the three-stage treatment method needs to use three treatment pools, the treatment pools occupy a large area and the investment cost is high;

2. The pipelines connecting the treatment pools are prone to blockage under long-term working conditions;

3. Most of the sedimentation tanks now use inclined tube sedimentation tanks. Because the inclined tubes of the inclined tube sedimentation tanks have an oblique angle of 60 degrees compared to the horizontal plane, unnecessary space is occupied at both ends of the inclined tubes;

4. When the sedimentation tank is treating heavily polluted or sludge-heavy sewage, there will be floating mud phenomenon caused by incomplete sedimentation of sludge or suspended pollutants;

5. The three treatment pools are independent of each other, and it is necessary to set up water distribution at the inlet end of each treatment pool according to certain process requirements.

Based on this, it is necessary to propose a sewage treatment device with a small footprint, low cost, and no phenomenon such as pipeline blockage and floating mud, so as to solve the above-mentioned problems.
