Biological reactor for sewage treatment

Abstract

The invention discloses a biological reactor for sewage treatment. The biological reactor structurally comprises a base, a water pump, a biological reaction structure, an overhaul port and a purifiedwater outlet; the water pump is vertically arranged on the upper end of the base and is mechanically connected; the biological reaction structure is horizontally arranged on the upper end of the baseand is connected with the water pump through a pipeline; the overhaul port is arranged on the biological reaction structure and is an integrated structure; the purified water outlet is vertically arranged on the upper end of the biological reaction structure and is welded; the biological reaction structure comprises a box body, a sewage inlet, a sewage biological treatment cavity, a water outlet cavity, a water discharge opening and a water flow control mechanism; and the sewage inlet penetrates through the left side of the box body. According to the invention, the water flow control mechanismis arranged on the sewage biological treatment cavity, so that the amount of sewage entering for treatment can be controlled according to the flowing speed of the sewage, the sludge load is kept in anormal state, and biological treatment capacity is improved, so that biological treatment efficiency is improved, and the sewage is further treated better.

Description

technical field [0001] The invention belongs to the field of bioreactors, and in particular relates to a bioreactor used for sewage treatment. Background technique [0002] Bioreactors mainly use the biological properties of organisms to react, so as to achieve some functions that are difficult for equipment to achieve. In bioreactors, organisms are used more and more widely, so more and more fields are processed, such as using In terms of sewage treatment, sewage is the most common. It mainly uses organisms to absorb and degrade pollutants, better purify sewage, and meet discharge standards. However, existing technologies have the following deficiencies: [0003] Due to the limited metabolic capacity of the utilization organisms, the efficiency in the treatment of pollutants is limited, so the biological treatment capacity will be reduced when the sludge load is large, and the biological treatment capacity will be excessive when the sludge load is small, resulting in sludge...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a bioreactor for sewage treatment to solve the problem that the existing technology has limited efficiency in treating pollutants due to the limited utilization of biological metabolism, so the sludge load When the sludge load is large, the biological treatment capacity will be reduced, and when the sludge load is small, the biological treatment capacity will be excessive, resulting in a reduction in the biological treatment capacity when the sludge load is large, thereby reducing the biological treatment efficiency and affecting the overall The problem of sewage treatment capacity
