Rotary adjustable anaerobic-anoxic-aerobic biochemical reactor

Abstract

The invention discloses a rotary adjustable anaerobic-anoxic-aerobic biochemical reactor. The rotary adjustable anaerobic-anoxic-aerobic biochemical reactor is in the form of a rotary channel, and are divided into 4 continuous water channels with equal width and height including an anaerobic segment, an anoxic segment, and an aerobic segment; volume distribution adjustment of the anaerobic segment, the anoxic segment, and the aerobic segment can be realized by moving movable separating plates; the lower parts of the movable separating plates are provided with water passing orifices; and the lower part of each channel of the rotary adjustable anaerobic-anoxic-aerobic biochemical reactor is provided with a controllable aerating apparatus. The rotary adjustable anaerobic-anoxic-aerobic biochemical reactor is reasonable in design and compact in structure; the channels are designed to be flexible, and adjustment is convenient and practicable; investment and operation cost is low; the relative hydraulic retention time of the anaerobic segment, the anoxic segment and the aerobic segment can be flexibly adjusted according to the water quality conditions of waste water to be treated; and when different waste water is treated or the water quality of the waste water to be treated is changed, overall stable and efficient treatment effects of the rotary adjustable anaerobic-anoxic-aerobic biochemical reactor can be maintained, and excellent environmental benefits and economic benefits are obtained.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and relates to a sewage treatment reactor, in particular to a rotary adjustable anaerobic-anoxic-aerobic biochemical reactor. Background technique [0002] The traditional A / A / O process is a typical urban sewage treatment process, which solves the problems of organic matter removal and nitrogen and phosphorus removal in sewage to a certain extent. The ratio of the hydraulic retention time of the anaerobic section, the anoxic section and the aerobic section of the traditional A / A / O process, that is, the ratio of the volumes of each reaction section, is generally 1:1:3~4, and the relative volume is fixed. Poor adjustability, for the treatment of industrial wastewater with special water quality, the hydraulic retention time and treatment load of each reaction section are difficult to adjust, and cannot fully adapt to some industrial wastewater with high concentration of refractory organic matter, hig...

AI Technical Summary

Problems solved by technology

The ratio of the hydraulic retention time of the anaerobic section, the anoxic section and the aerobic section of the traditional A / A / O process, that is, the ratio of the volumes of each reaction section, is generally 1:1:3~4, and the relative volume is fixed. Poor adjustability, for the treatment of industrial wastewater with special water quality, the hydraulic retention time and treatment load of each reaction section are difficult to adjust, and cannot fully adapt to some industrial wastewater with high concentration of refractory organic matter, high nitrogen and high phosphorus, which limits the application of this type of biochemical reactor Development and Application

[0003] Chinese patent CN201110157920.0 discloses "an adjustable biochemical pool and its adjustable A / A / O process for water treatment". Although the process is changeable, it fails to fundamentally change the anaerobic section and the anoxic section respectively. and the actual volume size of the aerobic section and the relative hydraulic retention time ratio

Chinese patent CN200510132777.4 "five-factor adjustable sewage treatment device", the volume ratio of anaerobic pool, anoxic pool and aerobic pool can be adjusted, but the anaerobic pool, anoxic pool and aerobic pool need to be arranged in sequence, and It is connected into a large rectangular pool and adjusted by moving partition walls, so it occupies a large area. The layout of the three biochemical reaction sections is single, difficult to adjust, and the application range is limited.
