It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure.

The livestock and poultry manure and the sewage for washing the breeding house contain various components such as abundant carbohydrates, fat, protein, mineral substances, vitamins and the like. These substances are the nutrient sources for the growth and reproduction of microorganisms, and are decomposed under anaerobic conditions to generate methane, organic acids, alcohols, ammonia gas, vinyl alcohol, dimethyl sulfide, hydrogen sulfide, methylamine, trimethylamine and other substances with unpleasant odor. And secondly, the gas discharged from the digestive tract of the livestock and poultry, the secretions of sebaceous glands and sweat glands, the pheromone of the livestock body and the dirt adhered to the body surface can also emit the peculiar smell of different livestock and poultry. The waste gas of sewage treatment stations, composting plants and harmless treatment plants is mainly sulfur compounds, nitrogen compounds and the like, and the waste gas of the composting plants also contains a large amount of dust.
The density of the livestock in the farm is extremely high, the activity is frequent, and the putrefaction of the excrement and the feed residue of the livestock is easy to breed viruses and bacteria. Bacteria can enter the bodies of the livestock through water, air, editors and the like to influence the growth performance of the animals; viruses in the air can enter the bodies of the livestock through respiratory tracts, so that the resistance of the livestock is reduced; the virus and bacteria can induce diseases, such as African swine fever virus, pseudorabies virus, foot and mouth disease virus, circovirus, diarrhea virus, blue ear virus and the like, the viruses have extremely high infectivity and pathogenicity, once one livestock is infected, large-area livestock cross infection is easily caused, and huge economic loss is caused in a farm.
