Description

Multistage innocent treatment anaerobic fermentation pond

Technical Field

The utility model relates to an anaerobic fermentation tank, in particular to a multistage innocent treatment anaerobic fermentation tank.

Background

The existing sanitary toilets mainly comprise four types: (1) a marsh gas sanitary toilet; (2) a sanitary toilet for separating excrement from urine; (3) a double-poly septic tank sanitary toilet; (4) three-grid type septic tank sanitary toilets. The marsh gas sanitary toilet can suffocate and kill parasitic ova and harmful bacteria and viruses contained in excrement and urine through anaerobic fermentation, and the generated harmful gas is purified and combusted to realize harmless treatment, so that the marsh gas sanitary toilet is the sanitary toilet with the best treatment effect in four sanitary toilets. However, if the marsh gas sanitary toilet is constructed, if marsh gas is not used, the cost for constructing the toilet is too high and the construction period is long, so that the marsh gas sanitary toilet is not convenient to popularize. In addition, the excrement and urine separation sanitary toilet separates excrement and urine, harmful viruses, germs and parasitic ova are not treated because the excrement and urine is not sealed in the storage process, and harmful odor is discharged into the atmosphere through the exhaust pipe to pollute the air, so that the problem is not solved substantially, and the excrement and urine separation sanitary toilet is waste of economic investment. The double-acting septic tank sanitary toilet adopts two-stage septic tank, and has the following problems: first, the septic tank sets up the odor elimination pipe, also can discharge harmful gas in the atmosphere, the contaminated air. And also oxygen is introduced through the odor exhaust pipe because the diameter of the odor exhaust pipe is large. Secondly, aerobic fermentation is adopted, the excrement inlet pipe is designed at the upper part of the septic tank, and air enters the septic tank through the excrement inlet pipe, so that harmful viruses, germs and parasitic ova can be absorbed by oxygen to breed, and diseases are transmitted to people and livestock. The three-format septic tank sanitary toilet has the problem that the design is unreasonable, and the first odor exhaust pipe arranged at the top of the septic tank can discharge harmful gas into the atmosphere and can also enter oxygen. The second design is the manure outlet pipe at the top of the septic tank, so that oxygen enters the septic tank, harmful viruses, germs and parasitic ova absorb the oxygen and breed a large amount in summer, and diseases are infected to people and livestock.
