Kitchen and household garbage recycling stations are mostly built around living areas, and because organic matters in the kitchen and household garbage recycling stations are decomposed, odor pollution is inevitably generated, and the living environment of residents is influenced. In addition, in the processes of storing, loading and unloading the household garbage and the kitchen garbage, tiling, compacting and the like in a landfill, the external release of malodorous gas cannot be avoided, and the influence on the surrounding human environment can be avoided. The natural degradation only takes a long time.
At present, public toilets and mobile toilets can generate odor diffusion in the use process as an important component of living facilities. And the public toilet and the mobile toilet septic tank are decomposed and degraded by natural strains all the time, the processing capacity is weak, fiber matters such as toilet paper and the like float and block to block the pipeline after a long time, the odor returning phenomenon occurs, and the odor of the well mouth of each large-city sewage pipeline is diffused. The prior treatment method is to clean the septic tank by a person at regular intervals, but floating objects which are cleaned become odor solid wastes which are difficult to treat. Therefore, the air deodorization and septic tank cleaning in public toilets and mobile toilets become an important subject for research.
The current plant often has very big peculiar smell and foul smell, and its excrement and urine and other emissions are all in the same degradation pond of collecting, discharge again after coming out through natural degradation. However, the traditional method cannot avoid the generation of odor and has long degradation period. The daily discharge of the farm is large, the degradation pond is quickly filled, and large discharge matters are discharged outside without being subjected to degradation treatment. This has a great influence on the surrounding environment.
In view of the odor generated in various living or production scenes, deodorizers for removing the odor of household garbage or the odor of a breeding place have appeared on the market. At present, deodorizers mainly comprise plant deodorizers, chemical deodorizers and multifunctional microbial deodorizers in the market. The plant deodorant is prepared by extracting plant essential oil to cover odor, but the pollutants cannot be decomposed, and when the plant essential oil is completely volatilized, the odor is revealed to form secondary pollution. Moreover, the extraction process of the plant deodorant is complex, difficult to obtain, high in production cost and incapable of being used on a large scale. Besides high cost, the chemical deodorant has hidden danger in use safety, and new compounds can be generated after the chemical deodorant reacts with odor to form unknown secondary pollution.
The current mature microbial multifunctional deodorant in the market utilizes EM (effective microorganisms) strains to breed and generate a large amount of bacteria, and then utilizes various bacteria with different attributes to swallow and decompose odor and garbage. The product has strict requirements on the environment in the use process, certain temperature and humidity are required for strain propagation, and the strain propagation is influenced by overhigh or overlow temperature and humidity, so the use is inconvenient.
