Abstract

The invention discloses a sewage treatment technique and in particular relates to a sewage treatment system used for treating domestic sewage. The system comprises at least one sewage input pipeline, an aeration tank, a water collection tank, at least one slope cant, at least one sewage output pipeline and at least one filtration unit, wherein the aeration tank is connected with a drainage pipeline; the drainage pipeline is arranged at the top of the slope cant; the water collection tank is formed in the bottom of the slope cant; the at least one sewage output pipeline is connected with the bottom of the water collection tank; the at least one filtration unit is arranged between the slope cant and the water collection tank or is arranged in the water collection tank. By virtue of the sewage treatment system, flow impellers are greatly reduced; even the flow impeller can be omitted, therefore, the building and maintenance costs of a sewage treatment tank can be reduced.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to a sewage treatment system for domestic sewage. Background technique [0002] At present, domestic sewage is mostly directly discharged into sewage pipes, and then discharged into rivers, rivers, lakes, and seas through sewage pipes. In some places, sewage is transported to sewage treatment plants, and after treatment, it is reused as reclaimed water, or discharged into rivers, rivers, lakes, and seas. Recently, some living quarters have provided septic tanks, through which sewage is infiltrated into the ground to treat sewage in this way. The above-mentioned sewage treatment method has many disadvantages: untreated sewage is discharged into rivers, rivers, lakes, and seas, directly causing water pollution. Reusing sewage after treatment in sewage treatment plants, or discharging sewage after treatment is better than direct discharge, but the cost of sewage treatment is high, and a...
