A large amount of pathogenic microorganisms contained in the layer chicken manure are diffused and spread through water or aquatic animals and plants, and the health of people and livestock is damaged. In addition, the content of nutrient substances such as nitrogen, phosphorus and the like in the excrement is rich, if the excrement excessively enters slow-flowing water bodies such as lakes, estuaries, gulfs and the like, water eutrophication can be caused, the problem of environmental sanitation inside and outside a laying hen farm is caused, the contribution of animal husbandry in the aspects of energy conservation and emission reduction is concerned, the sustainable development of laying hen breeding is further restricted, besides the pollution, stink generated by the excrement of the laying hen farm can pollute the surrounding atmospheric environment, the stink becomes an infection path for infectious diseases of laying hen infectious diseases, parasitic diseases and human and poultry, the original mode of artificial excrement cleaning and compost fermentation is changed, at present, mechanical or semi-mechanical excrement treatment is mostly adopted, and the excrement liquid is purified through a reaction tank inside the shell, so that the excrement liquid is discharged from the outer end of the shell for reutilization.
A dirty excrement processing apparatus of current stage has more shortcoming: for example, the treatment of the waste manure cannot be subdivided, the liquid and the solid material inside the waste manure cannot be treated separately, which results in much waste, and the procedures in the more-developed treatment processes are complicated and waste of labor and materials.
