Septic tank

Abstract

The invention relates to a purification tank. The purification tank comprises a water inlet pipe, a tank body, a water output pipe, a plurality of slag removing holes and slag removing hole caps, wherein the water inlet pipe is used for connecting gathered sewage flowing out of a toilet, a kitchen and a bathroom; the slag removing holes and the slag removing hole caps are arranged at the upper end of the tank body; the tank body is sequentially divided into an anaerobic chamber, an aeration chamber, a sedimentation chamber and a sterilization chamber from left to right; a circulating pump is arranged in the anaerobic chamber. The purification tank is scientific in design and ingenious in conception, the sewage retention time is short and is not longer than 30 min, and little stink is produced; energy and consumable items are not required, the maintenance is simple, the operating cost is not required, and the operating management is facilitated; the purification tank can be used for longer than 100 years normally, is resistant to corrosion of multiple chemical substances such as acid, alkali and the like, can bear direct sunlight, has high antioxidant capacity and can be normally used in the environment at the temperature ranging from subzero 60 DEG C to 200 DEG C, and the environment pollution is effectively reduced.

Description

Technical field [0001] The present invention relates to a purification tank. Background technique [0002] At present, most of the sewage flowing out of the toilet, kitchen, and washing room is directly discharged into the septic tank for storage without purification. Septic tanks only store these domestic sewage, and then discharge these unpurified domestic sewage directly into rivers, ponds, lakes, and the ocean after a period of time. This is the direct cause of environmental pollution. In addition, there are also some pretreatment devices, most of which use physical precipitation methods, which can effectively remove particulate solid pollutants, but for colloidal and soluble pollutants, their effect is very small; and there are longer sewage retention times and incomplete sewage discharge. , High maintenance costs, short service life, weak adaptability to the environment and many other defects. Summary of the invention [0003] The technical problem to be solved by the pres...
