Integrated underground SBR (sequencing batch reactor) sewage treatment device and method

Abstract

The invention discloses an integrated underground SBR sewage treatment device and method. The integrated underground SBR sewage treatment device comprises a collecting tank, a regulating tank, an SBR tank, a collecting tank lift pump, a regulating tank lift pump, an SBR tank jet aerator, an SBR tank discharge pump, a water inlet pipe, a collecting tank lift pipe, a regulating tank lift pipe, an SBR tank discharge pipe and a jet aerator air inlet pipe, wherein the collecting tank is connected with the water inlet pipe, and the inside of the collecting tank is provided with the collecting tank lift pump and the collecting tank lift pipe; the inside of the regulating tank is provided with the regulating tank lift pump and the regulating tank lift pipe; the SBR tank is provided with the SBR tank jet aerator, the SBR tank discharge pump, the SBR tank discharge pump, the SBR tank discharge pipe and the jet aerator air inlet pipe. The integrated underground SBR sewage treatment device can reduce floor area occupation, avoid odor of above-ground buildings as well as impact on integral architectural layout. A sewage system is automatically controlled through PLC (programmable logical controller); through treatment, indexes in sewage such as organic matters, ammonia nitrogen, total nitrogen and total phosphorus can be eliminated, and the labor intensity and the labor time can be reduced for workers.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a sewage treatment device, in particular to an integrated buried SBR sewage treatment device; meanwhile, the invention also relates to a sewage treatment method. Background technique [0002] Water pollution prevention and control is an important part of the country's environmental pollution control, and it undertakes a major mission to improve the environmental pollution situation. my country's water environment pollution control technologies are mainly based on physical methods, chemical methods, and biological methods. According to different sewage characteristics and requirements, corresponding single or combined treatment methods are adopted to meet the corresponding discharge standards. Among them, the biological method is a relatively common and widely used method, which uses microorganisms to degrade organic matter in water. Compared with other treatment methods, ...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used biological treatment methods for domestic sewage include activated sludge method, biological contact oxidation method, SBR and various deformation methods, but such treatment methods need to add other auxiliary equipment in addition to the biological treatment tank body

In addition to building an underground pool, an above-ground equipment room must be added. In addition, the removal of domestic sewage and equipment operation will also emit odors to the surrounding area, affecting the surrounding environmental sanitation

Compared with other biological treatment methods, the SBR treatment method has a high degree of intensification and does not need to build additional sedimentation tanks. However, in the treatment process of traditional SBR tanks, external aeration equipment and decanters are also required, and SBR tanks are often placed On the ground, occupying a certain amount of space
