Description

Anaerobic tank for domestic sewage treatment

Technical Field

The embodiment of the utility model relates to the technical field of sewage treatment, concretely relates to anaerobism pond that domestic sewage treatment used.

Background

The anaerobic tank utilizes the function of anaerobic bacteria to hydrolyze, acidify and methanize the organic matters, remove the organic matters in the wastewater, improve the biodegradability of the sewage and be beneficial to subsequent aerobic treatment. The anaerobic degradation process of the high molecular organic matter can be divided into four stages: hydrolysis stage, acidification stage, acetogenesis stage and methanogenesis stage. A hydrolysis stage: due to the large molecular volume of the macromolecular organic matter, the macromolecular organic matter can not directly pass through the cell wall of anaerobic bacteria, and needs to be decomposed into small molecules by extracellular enzymes outside microorganisms. Typical organic substances in wastewater such as cellulose are decomposed into cellobiose and glucose by cellulase, starch is decomposed into maltose and glucose, and protein is decomposed into short peptides and amino acids. The decomposed small molecules can enter the cell body through the cell wall to be decomposed in the next step. And (3) acidification stage: the small molecular organic matter enters the cell body to be converted into simpler compounds and is distributed outside the cell, and the main products of the stage are volatile fatty acid and partial products of alcohol, lactic acid, carbon dioxide, hydrogen, ammonia, hydrogen sulfide and the like are generated. An acetic acid production stage: at this stage, the product of the last step is further converted into acetic acid, carbonic acid, hydrogen and new cellular material. A methanogenesis stage: at this stage, acetic acid, hydrogen, carbonic acid, formic acid and methanol are all converted to methane, carbon dioxide and new cellular material. This phase is also the most important phase of the whole anaerobic process and the rate-limiting phase of the whole anaerobic reaction process.
