The disadvantages are as follows: the natural oxidation method has long time, requires large area of an oxidation pond, and is difficult to be matched with a common small and medium-sized farm; indexes such as colibacillus, roundworm eggs and the like in the natural oxidation hardly reach the standard of land absorption; the problems of odor and flies caused by a large area of oxidation pond are easy to cause trouble of surrounding residents. (3) An industrial method: the sewage is treated into COD and VOD through medicaments or microorganisms by adopting an industrialized flow, reaches the discharge standard, and can be merged into a municipal sewage pipe network. The disadvantages are as follows: the investment is huge, the method is not suitable for most farms, and the feces are not recycled.

Under the conditions of proper temperature, humidity and pH value, the excrement can generate methane through the microbial fermentation. Biogas is a combustible gas mixture whose main component is methane and secondly carbon dioxide. In addition, it contains small amounts of nitrogen, hydrogen, oxygen, ammonia, carbon monoxide and hydrogen sulfide (H)₂S), and the like. The methane is a renewable clean gas fuel, widely exists in rural areas, but the utilization rate is not high. The existing biogas technology is used for building the biogas digester, the cost is high, common farmers cannot bear the biogas digester, and when the biogas is conveyed to peripheral users for use, the biogas digester needs to be pressurized by various methods to achieve the pressure of biogas conveying, so that the construction difficulty is increased, and the management and maintenance of the biogas digester are not facilitated.
