Two-phase integrated anaerobic reactor

Abstract

The invention discloses a two-phase integrated anaerobic reactor. The reactor (1) consists of a hydrolysis and acidification pool (1a) and a methane producing pool (1b), wherein a flow guide plate (6) and a partition board (7) are arranged in the hydrolysis and acidification pool (1a) in a longitudinal and staggered manner to form an S-shaped water channel; the lower end of the flow guide plate (6) has a 40 to 45-degree bend; the lower part of the methane producing pool (1b) is communicated with the acidification pool (1a); and a water inlet (2) is higher than a water outlet (3). In the invention, through the integrally designed reaction, a hydrolysis and acidification phase and a methane producing phase are combined in a reactor, so the number of reactors is reduced, and floor area is reduced; the S-shaped water flow channel and the flow guide plate of which the lower end has a bend are combined to increase the mixing degree of water and sludge, so the treatment effect of the reactor is improved; and the design that the water inlet is higher than the water outlet and other design make the system hardly consume any energy.

Description

technical field [0001] The invention relates to wastewater anaerobic biological treatment technology, in particular, it is a novel high-efficiency two-phase integrated anaerobic reactor. Background technique [0002] The traditional two-phase anaerobic reaction process is divided into two processes: hydrolytic acidification and methane production, which are completed in two independent reactors. The main purpose of the hydrolytic acidification process is to improve the biodegradability of the substrate and provide a suitable substrate for methanogenesis; the main purpose of methanogenesis is to convert the substrate provided by the acidification process into methane, and the two together constitute a two-phase anaerobic reaction process. This process needs to be carried out in two separate reactors, which increases the capital construction cost and floor area. Due to the increase in the number of reactors, the operation and maintenance costs and heat loss during the reaction...
