Two-channel self circulation anaerobic bioreactor

Abstract

The invention discloses a dual-channel self-cycle anaerobic bioreactor. The anaerobic bioreactor is provided with a reactor body and a bracket. The reactor body consists of a left cavity and a right cavity, wherein, the right cavity is a reaction system which is provided with an up-flow reaction room, a water inlet pipe, a sampling port, a sludge discharging pipe and a sludge sedimentation zone from bottom to top, and the left cavity is a sludge sedimentation system which is provided with an overflow weir, a sedimentation room, a circular tube and a return room from top to bottom. The left cavity and the right cavity are communicated by the circular tube; and the upper end of the circular tube is connected with the sludge sedimentation zone of the right cavity and the lower end thereof iscommunicated with the top of the return room of the left cavity. The invention has the advantages that: 1) the reaction room is separated from the sedimentation room, so that the flow pattern of the reaction room has less influence on the working condition of the sedimentation room; 2) the reaction room is communicated with the sedimentation room by the circular tube, so that substrate transmission is strengthened and self balance of alkalinity and nutrition is achieved; and 3) the reactor can withstand high influent organic substance concentration and has strong impact load resistance capacity.

Description

technical field [0001] The invention relates to a double-channel self-circulation anaerobic bioreactor. Background technique [0002] Anaerobic biological treatment technology is the process of converting organic pollutants into biogas by using the metabolism of microorganisms under anaerobic conditions, so as to purify sewage. Compared with aerobic biological treatment, anaerobic biological treatment has the characteristics of low energy consumption, low sludge production, and the ability to recover clean energy (biogas). It is an effective means of saving energy and protecting the environment, and has a very broad application prospect. [0003] The research on anaerobic bioreactors has a history of more than 100 years. With the deepening of people's understanding of anaerobic biological processes and the popularization of anaerobic biological treatment technology applications, anaerobic bioreactors have also been better developed. develop. So far, anaerobic bioreactors h...

Problems solved by technology

For example, the EGSB reactor requires liquid reflux, which not only increases power consumption, but also makes the reactor fully mixed, making it difficult to further improve the treatment efficiency and effluent quality

Before the internal circulation of the IC reactor is realized, short flow is prone to occur, and operation control is relatively difficult; in addition, the hydraulic retention time is relatively short and the height-diameter ratio is large, and the effluent contains fine particle sludge (precursor to form large particle sludge) More, making the subsequent sedimentation unit a necessary equipment
