Circulating bioreactor for livestock and poultry breeding sewage treatment

Abstract

The invention discloses a circulating bioreactor for livestock and poultry breeding sewage treatment. The structure of the circulating bioreactor comprises an end cover, a gas collecting pipe, an outer frame and a reaction barrel; the end cover is mounted at the upper end of the gas collecting pipe; the gas collecting pipe extends into the reaction barrel; the outer frame is arranged on the surface of the reaction barrel; a discharging mechanism, a biological filler tank, a reaction cavity, a backwashing pipe and a sludge discharging opening are formed in the reaction barrel; the discharging mechanism is mounted at the upper end of the biological filler tank; the biological filler tank and the backwashing pipe are arranged in a reaction cavity; a discharging port and a feeding port are formed in the two opposite sides of a biological reaction tank respectively, the discharging port and the feeding port correspond to an upper cavity and a lower cavity respectively, the two cavities areseparated, and when materials are stored in the upper cavity, the lower cavity is still in a closed state, so that the internal sealing performance is constant during continuous feeding, and the stability of the internal environment is guaranteed.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a circulating bioreactor for sewage treatment of livestock and poultry breeding. Background technique [0002] No matter what process or comprehensive measures are used to treat livestock and poultry wastewater, certain pretreatment measures must be taken. Pretreatment can reduce the pollutant load of wastewater, and at the same time prevent large solids or debris from entering the subsequent treatment process, causing equipment blockage or damage, etc. There are many treatment methods for livestock and poultry breeding wastewater, including natural treatment, exhaustion Oxygen method, aerobic method and mixed treatment method. The existing mixed treatment method adopts bioreactor for treatment. Bioreactor refers to the use of naturally occurring microorganisms or microorganisms with special degradation ability to inoculate liquid or solid phase Compared with solid-phase systems,...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a circulating bioreactor for livestock and poultry breeding sewage treatment, which is used to solve the need for uninterrupted equipment feeding in continuous degradation. In continuous feeding, the sealing of the feeding port is reduced, and Untimely discharge of old materials leads to the mixing of new and old materials, resulting in poor degradation environment inside the reactor and insufficient reaction of new materials.
