BSTS short-range biological sewage treatment system and process

Abstract

The invention discloses a BSTS short-range biological sewage treatment system and process in the technical field of sewage treatment.The BSTS short-range biological sewage treatment system comprises a pretreatment pond, a fine treatment pond and a sedimentation pond, the pretreatment pond is communicated with the fine treatment pond, and the fine treatment pond is communicated with the sedimentation pond; the inner side of the pretreatment tank is provided with an adjusting mechanism which is used for automatically detecting the sewage condition and automatically adding chemicals for adjustment, and the bottom of the pretreatment tank is provided with an automatic aeration mechanism; through intelligent adjustment in the pretreatment tank, a complex and changeable water body is adjusted into a water body suitable for entering the pretreatment tank, various surplus microorganisms in sewage are effectively removed through a more accurate nitrification and denitrification reaction of the pretreatment tank, and then the sewage is discharged into the advanced treatment tank, is subjected to more accurate confirmation and fine adjustment and then is discharged into the sedimentation tank; and high-quality emission is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a BSTS short-range biological sewage treatment system and process. Background technique [0002] With the growing urban population and the continuous development of industry and agriculture, water pollution accidents occur frequently, seriously endangering the health and even life of humans and animals. The discharge of nitrogen and phosphorus in many lakes and reservoirs causes water eutrophication, which seriously threatens the production, life and ecological balance of human beings. [0003] At present, there are innovations in the field of sewage treatment, including various simultaneous nitrification and denitrification processes, deep denitrification processes, and bacterial biological treatment agents. However, most of them are limited to laboratory theoretical research. In the face of complex and changeable actual water conditions, it is difficult to find stable...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a BSTS short-range biological sewage treatment system and process, to solve the current innovation in the field of sewage treatment proposed in the above background technology, there are various synchronous Nitrification and denitrification process, deep denitrification process, bacterial strain biological treatment agent, etc.

However, most of them are limited to laboratory theoretical research. In the face of complex and changeable actual water conditions, it is difficult to see stable, effective and low-cost innovative technology on the market, and the existing sewage treatment is carried out in sedimentation tanks for sludge sedimentation. At this time, it takes a long time for the impurities in the sewage to fall to the bottom of the sedimentation tank, and some floating small particles cannot settle by themselves, which leads to a long time for the sludge to settle, and the precipitation is not complete, which affects the quality of the subsequent discharged sewage.
