Anaerobic hydrolysis and acidification pool

Abstract

The invention discloses an anaerobic hydrolysis and acidification pool which comprises a reaction region and a muddy water separation region, wherein the reaction region is provided with a plurality of water inlets and a plurality of water distribution holes, the muddy water separation region is provided with a plurality of muddy water inlets and a plurality of water outlets, the muddy water inlets are connected with the water distribution holes, a stirrer is arranged at a sludge part of the reaction region, the water inlets of the reaction region are provided with a plurality of flow diverters, and each flow diverter leads the wastewater flowing direction and the sludge flowing direction stirred by the stirrer to form an angle. The pool has the advantages of being even in water distribution and higher in hydraulic stirring so as to form a good microorganism and wastewater reaction system, and is more efficient in treatment effect, further the pool is small in floor space, less in equipment, less in investment, and more convenient to run and manage.

Description

technical field [0001] The invention relates to an acidification pond, in particular to an anaerobic hydrolysis acidification pond. Background technique [0002] The anaerobic hydrolytic acidification tank can take advantage of the difference in growth rate between methanogenic bacteria and hydrolytic acid-producing bacteria, and the elutriation effect of flowing water in the reaction tank makes it difficult for methane bacteria to reproduce in the reaction tank, and the anaerobic treatment is controlled within the reaction time The short first stage is to hydrolyze insoluble organic matter into soluble organic matter under the action of a large number of hydrolytic bacteria and acid-producing bacteria, and convert difficult biodegradable macromolecular substances into easily biodegradable small molecular substances. [0003] The anaerobic hydrolysis treatment in the anaerobic hydrolysis acidification tank is used as the pretreatment of various biochemical treatments, which ...

AI Technical Summary

Problems solved by technology

The first two anaerobic treatment processes are limited by the uniformity of water distribution, while the anaerobic hydrolysis process with sludge external return is less efficient and occupies a larger area

[0005] For example, in the Chinese patent "integrated circulation anaerobic hydrolysis tank" with the patent application number "200920196992.4", the hydrolysis tank and the separation tank are arranged on a plane, which occupies a large area; and the propeller is used to promote the flow of sludge and sewage, but The flow direction of sludge and sewage is the same, and the mass transfer efficiency of the biochemical reaction is low; in addition, the use of a reflux pump to return the sludge is expensive, so the efficiency of the hydrolysis process in the hydrolysis tank is low
