With the improvement of living standard, the demand of people for meat, eggs and milk products is increasing day by day, meanwhile, the breeding industry is rapidly developed, the number of farms is more and more, and the excrement of livestock and poultry is increased.
In a farm, the conventional way of disposing of livestock manure is to dump the manure directly to the farmland surrounding the farm or to the waste open space. However, the feces of livestock and poultry which has just been discharged contain NH3, H2When harmful gases such as S, amine and the like are not removed in time, odor is multiplied, malodorous gases cause air dirt and mosquitoes and flies to breed, and a large amount of livestock and poultry excrement is accumulated for a long time to lead the number of harmful bacteria in the environment to be in an increasing trend. In addition, in the place where the excrement is piled or flowed through, a large amount of high-concentration liquid dung permeates into the soil, so that the plants grow excessively for a while, or the root systems of the plants are damaged, and even the plants die. In a serious situation, the infiltration of the liquid dung into the underground water can cause the nitrate nitrogen, the hardness and the total number of bacteria in the underground water to be seriously out of the standard. According to the determination, when the livestock and poultry dung water flows into the pond and the ammonia content in the water reaches or exceeds 0.2mg/L, the toxicity is generated to the fish; if the water flows into the drinking water source, the water can become a source for spreading diseases, so that the disease resistance and the productivity of the livestock are reduced, the survival, the growth and the development of the livestock are influenced, the environment is polluted, and the health of human bodies is endangered.
