Problems solved by technology

If the sludge growth rate is lower than the sludge loss rate, the reactor will eventually fail
In addition, the high volumetric gas production rate will also generate a large number of short flows, which will affect the substrate conversion

Abstract

The present invention discloses an auger type self circulation bioreactor comprising a reactor body and a support; wherein the reactor body is provided with a plug flow reaction chamber and a baffle board sediment chamber, the plug flow reaction chamber is provided with a first sludge discharge pipe and a return pipe at the bottom and the center respectively; a plurality of spiral laminas are arranged using the return pipe as axes, and are provided with an intake pipe for each at the underlayer; the baffle board sediment chamber is provided with an outside cylinder diffuser at the bottom; the center of the baffle board sediment chamber is provided with a plurality of baffle boards which are interlaced up and down and are vertically parallel with each other; the entrance of the baffle board sediment chamber is provided with a gas-liquid riser which is connected with the top end of the plug flow reaction chamber at the other end; the exit of the baffle board sediment chamber is provided with an overflow weir and an outlet pipe; the top end of the baffle board sediment chamber is provided with a blind flange which is provided with an exhaust pipe at the center part. The present invention is capable of inhibiting short flow and gas kick, adjusting acid-base equilibrium and matrix equilibrium, improving the sediment behavior, having high capacity load, capacity conversion efficiency and capacity gas generation efficiency, and having resistance of matrix and hydraulic loading impact.

Description

technical field [0001] The invention relates to a spiral self-circulation 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 output, and the ability to recover clean energy (biogas). It is one of the effective means to realize circular economy and has broad application prospects. [0003] With the deepening of people's understanding of anaerobic biological processes and the popularization of the application of anaerobic biological treatment technology, anaerobic bioreactors have also been better developed. So far, anaerobic bioreactors have been developed to the third generation of high-efficiency reactors represented by anaerobic granular sludge expanded ...
