Abstract

The invention relates to an integrated hydrolysis acidification and anaerobic fermentation device. The device comprises an anaerobic tank, a hydrolysis acidification tank, an aeration system and a feeding system, wherein the hydrolysis acidification tank is mounted in the anaerobic tank; the hydrolysis acidification tank is communicated with the interior of the anaerobic tank through an overflow opening in the upper end; the aeration system is communicated with the bottom of the hydrolysis acidification tank through an aeration pipeline; the feeding system is communicated with bottom of the hydrolysis acidification tank through a feeding pipeline. According to the hydrolysis acidification and anaerobic fermentation integrated device, the hydrolysis acidification and the anaerobic fermentation are integrated, so that the floor space of the device is decreased; the hydrolysis acidification process is separated from a biogas production process, and the two processes do not affect each other and are mutually synergetic, so that compared with the conventional anaerobic fermentation tanks, the device is capable of effectively improving the volumetric gas production rate and biogas production rate of the anaerobic fermentation tank.

Description

technical field [0001] The invention relates to the application field of new energy and energy-saving technologies, in particular to an integrated device for hydrolytic acidification and anaerobic fermentation. Background technique [0002] Anaerobic fermentation of organic waste refers to the process of decomposing and converting various complex organic matters in wastewater into methane and carbon dioxide through the action of anaerobic microorganisms (including facultative microorganisms) under the condition of no molecular oxygen. Anaerobic fermentation process: The anaerobic degradation process of polymer organic matter can be divided into four stages: hydrolysis stage, fermentation (or acidification) stage, acetogenic stage and methanogenic stage. [0003] At present, when biogas projects or sewage treatment projects adopt two-phase anaerobic fermentation technology, they basically adopt hydrolytic acidification and anaerobic fermentation separation, and independently ...
