Heating type integrated sewage treatment device

Abstract

The invention discloses a heating type integrated sewage treatment device. In the sewage treatment device, a reactor (1) is divided to a hydrolysis-acidification tank (1a), a methane-producing tank (1b) and a transition zone (1c) by baffles (6) which are arranged longitudinally, wherein the upper part of the hydrolysis-acidification tank (1a) is communicated with the lower part of the methane-producing tank (1b) through the transition zone (1c); and the sewage treatment device also comprises a mixer (7) and a solar heat transfer system (8). By adopting the device disclosed by the invention, hydrolysis-acidification and methane producing are combined in a reactor; the transition zone is arranged between the hydrolysis-acidification tank and the methane-producing tank to ensure that sewage can flow into the lower part of the methane-producing tank from top to bottom; and the solar heat transfer system is combined, thus the sewage temperature can be increased, the mass transfer effect between sludge and water can be increased, and the device is good for acid-producing bacteria and methanogens and is very energy-saving and environmentally friendly.

Description

technical field [0001] The present invention relates to wastewater anaerobic biological treatment technology, in particular to a novel and efficient two-phase integrated sewage treatment device. Background technique [0002] The traditional two-phase anaerobic reaction process is divided into two processes, hydrolysis acidification and methane production, which need to be carried out in two separate reactors respectively. The hydrolysis and acidification process is mainly to improve the biodegradability of the substrate and provide a suitable substrate for methane production; methanogenesis mainly converts the substrate provided by the acidification process into methane, which together constitute a two-phase anaerobic reaction process. [0003] At present, the two-phase integrated anaerobic reactor is a new type of high-efficiency wastewater anaerobic treatment equipment, which completes the two processes of acidification and methane production in one reactor, and its common...

AI Technical Summary

Problems solved by technology

[0003] At present, the two-phase integrated anaerobic reactor is a new type of efficient wastewater anaerobic treatment equipment, which completes the two processes of acidification and methane production in one reactor, and its common arrangement is vertical or sleeve structure , there are problems such as complex structure, difficult installation, and poor mass transfer effect; on the other hand, the sewage is directly connected to the acidification tank through pipelines, especially in winter when the temperature is low, and the low temperature of sewage water is not conducive to the formation of acidification bacteria. The treatment effect of the reactor is greatly reduced
