Deep sewage treatment equipment

Abstract

The invention discloses deep sewage treatment equipment, which comprises a shell, wherein an adjusting tank, a reaction sedimentation tank, an anoxic and anaerobic reaction tank, an aerobic contact reaction tank, a secondary sedimentation tank, a disinfection tank, a sludge concentration tank and an equipment room are sequentially arranged in the shell in the horizontal direction, a wastewater inlet pipe and a first water outlet pipe are respectively arranged on two opposite side walls of the adjusting tank, and sludge outlets are formed in the bottoms of the adjusting tank, an oxidation reaction tank, a biological reaction tank, a primary sedimentation tank, a facultative reaction chamber, an anoxic reaction chamber, an anaerobic reaction chamber, the aerobic contact reaction tank and thesecondary sedimentation tank, and are communicated with the sludge concentration tank through sludge discharge pipelines. The equipment is simple in structure and low in preparation cost, has a gooddeep treatment effect on sewage, and is good in effluent quality.

Description

technical field [0001] The invention relates to various fields of sewage treatment technology, in particular to a sewage advanced treatment equipment. Background technique [0002] With the development of society, the pollution of water resources is also serious. There is an urgent need for sewage treatment technology suitable for the development of the times and to achieve reuse to alleviate the shortage of water resources. Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc. . The sewage treatment device is a device specially used to treat sewage. It can carry out multi-level classification treatment on sewage, so that the sewage can meet the discharge standard, can better reduce the pollu...

AI Technical Summary

Problems solved by technology

[0003] However, the existing sewage treatment methods can be divided into traditional activated sludge method, biological filter method, biological contact oxidation method, etc. In the process of sewage treatment, it needs to be divided into different process stages, and the sewage is passed through each stage in turn. The treatment operation is carried out in the equipment corresponding to the process stage. The entire sewage treatment process is time-consuming and labor-intensive, and the degradation effect on organic matter is poor. The process operation control is complicated and the effluent water quality is not stable.
