Because the garbage collection is the periodic collection, the garbage treatment capacity of the garbage treatment plant is limited, the phenomenon of garbage stacking often occurs, and particularly in hot summer, the odor becomes more serious due to the fact that the microbial fermentation action is accelerated in the stacked garbage. The odor of the household garbage comprises ammonia gas, hydrogen sulfide, organic amine, organic sulfur, volatile fatty acid and the like. The malodorous substances are various in types and wide in sources, can cause toxicity to human breath, digestion, cardiovascular diseases, endocrine diseases and nervous systems to different degrees, and aromatic compounds such as benzene, toluene, styrene and the like can also cause distortion and canceration of human bodies. Therefore, people pay attention to how to effectively treat the odor of the garbage.
At present, the treatment method of the household garbage stink comprises a physical method, a chemical method, a biological method and a covering method. The physical deodorization method is to utilize an adsorbent to adsorb and fix odor, the adsorption capacity of the method is greatly reduced along with the time extension, and the adsorption deodorization effect is lost after the adsorption saturation is reached, and the method cannot generate effect on the surface and the inside of the garbage; the traditional chemical method cannot be widely applied due to the problems of short action time, large loss, large medicament dosage and the like by adding various oxidants, and most chemical reagents contain components which stimulate respiratory tracts, such as acetaldehyde and styrene, and are easy to cause anaphylactic reaction; the biological method for deodorization by adopting microbial flora has the problems of difficult strain screening, culture and preservation, poor stability of deodorization effect due to the influence of temperature and the like; the covering method is to cover the odor by using the essence, so that odor components are not reduced, and toxic and harmful gases emitted by garbage can still cause harm to human bodies. Therefore, it is required to develop a garbage deodorant which has a strong bactericidal effect, can quickly and effectively deodorize, is safe and nontoxic, and does not cause harm to the environment and human bodies.
