[0002] Sewage refers to the discharged water from life and production that is contaminated to a certain extent. Water that has lost its original use function is simply called sewage. It is mainly the water used in daily life, which contains a relatively large amount of organic matter and is relatively easy to treat. From the perspective of the source of sewage, sewage can be defined as the liquid or water carrying waste that is discharged from residential, institutional, commercial or industrial areas and mixed with groundwater, surface water, snowstorms, etc. In order to avoid sewage polluting the environment, it is necessary to purify and treat sewage through a sewage treatment device.

[0036] Working principle: Wastewater from toilets and domestic activities enters the interior of the septic tank 1 through the collection pipe 6, and wastewater from the kitchen and dining areas enters the interior of the oil separation tank 2 through the collection pipe 6. The sewage discharged from the septic tank 1 and the oil separation tank 2 flows into the interior of the grille tank 3 through the clear liquid pipe A7. Through the grille 8 inside the grille tank 3, the coarse particle residues in the sewage are filtered on the left side of the grille tank 3. The filtered sewage enters the interior of the regulation tank 4 through the clear liquid pipe B9. By starting the sewage pump 23 through the artificial control system, the sewage pump 23 pumps the sewage inside the regulation tank 4 through the water inlet pipe 10. The pumped sewage flows into the interior of the first micro-electrolysis pipe 27 through the sewage pipe 24.

The physically and chemically decomposed sewage is discharged into the electro-chemical decomposition tank through the water outlet 34. The physically and chemically decomposed sewage enters the anaerobic tank through the first connecting pipe 17. The sewage in the anaerobic tank utilizes the action of anaerobic bacteria to remove the organic matter in the wastewater. The sewage in the anaerobic tank enters the anoxic tank through the second connecting pipe 18. The sewage in the anoxic tank enters the aerobic tank through the third connecting pipe 19. The sewage in the aerobic tank enters the first electrocoagulation pipe 37 in the sedimentation tank through the fourth connecting pipe 20. By starting the aeration blower 41, the aeration blower 41 aerates the anoxic tank and the aerobic tank through the air outlet pipe 42, the air supply pipe 43, and the aeration pipe 44 to decompose the organic matter in the sewage. The sewage after the decomposition of the organic matter is electrolyzed through the first electrocoagulation pipe 37, and the harmful substances in the sewage are converted into harmless substances through oxidation-reduction reactions. The sewage after oxidation-reduction flows into the sedimentation tank for sedimentation of the sewage. The sedimented sewage flows into the ultraviolet disinfection device 22 through the fifth connecting pipe 21. The sedimented sewage is sterilized and disinfected through the ultraviolet disinfection device 22. The water after sterilization and disinfection enters the clean water buffer tank. After being detected by the staff, it is ensured that the purified water meets the discharge standards.
