Problems solved by technology

Using activated sludge to treat sewage will produce sludge that needs to be discharged, and because the discharged sludge contains a large amount of organic matter, ammonia nitrogen, phosphorus, heavy metals and other substances, and has a high moisture content, the discharged sludge can only be incinerated, Landfill treatment, the cost of these treatment methods is high, the storage and transportation of sludge are inconvenient, and it is easy to cause soil and water pollution, which makes sludge treatment a major problem to be solved in the sewage treatment system

Abstract

The invention belongs to the technical field of sewage treatment and provides a sewage treatment system. The sewage treatment system comprises a sewage treatment passage which at least comprises an anaerobic tank, an aerobic tank, a sedimentation tank and a reaction tank, ferrate is adopted for sewage treatment in the reaction tank, and the anaerobic tank, the aerobic tank and the sedimentation tank are in sequential communication. A first output end of the sedimentation tank is communicated with the anaerobic tank or the aerobic tank, an input end of the reaction tank is communicated with a second output end of the sedimentation tank, an output end of the reaction tank is communicated with the sewage treatment passage, and sludge generated in the sedimentation tank is outputted through the first output end and the second output end respectively. The sewage treatment system has the advantages that sludge output in a sewage treatment process can be greatly reduced, and accordingly sludge treatment cost is reduced, and sewage treatment cost is reduced as well; in addition, ammonia nitrogen, phosphorus and organics in the sludge can be reduced, and consequently quality of water discharged from the sewage treatment system is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] At present, in the field of sewage treatment technology, activated sludge is widely used for wastewater treatment. Activated sludge is a general term for microbial groups and their attached organic and inorganic substances. Activated sludge can be divided into aerobic activated sludge and anaerobic granular activated sludge. Activated sludge is mainly used to treat sewage. Using activated sludge to treat sewage will produce sludge that needs to be discharged, and because the discharged sludge contains a large amount of organic matter, ammonia nitrogen, phosphorus, heavy metals and other substances, and has a high moisture content, the discharged sludge can only be incinerated, Landfill treatment, the cost of these treatment methods is high, the storage and transportation of sludge are inconvenient, and it is easy ...
