Embodiment Construction
[0016] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0017] see figure 1 , a processing technology of pig excrement, concrete steps are as follows:
[0018] (1) The flushing wastewater from each pig farm enters the sump through the grid canal to remove coarse particles, and the fresh pig manure is discharged into the sump for soaking for 1-2 days to remove crude fiber substances;
[0019] (2) Pump the pig manure in the sump into the manure adjustment tank, so that the TS concentration of the pig manure is 3-5%;
[0020] (3) Use a cutting pump to lift the pig manure in the manure adjustment tank to the USR reactor for fermentation;
[0021] (4) After desulfurization and purification, the biogas generated in the USR reactor enters the flexible membrane gas holder for storage, and the stored biogas is sent to the user unit for power generation or directly used in the heating boiler to provide heat for...

The invention discloses a processing process of pig excrement. According to the processing process, excrement and flushing wastewater of a pig farm are fed to an excrement regulating tank after being preprocessed by virtue of a water collection tank and are fermented by a USR reactor, produced biogas enters a flexible membrane type gas storage cabinet to be stored after being desulphurized and purified, the stored biogas is fed to a user unit for generating electricity or is directly fed to a warming boiler to heat and warm the USR reactor, produced biogas residue is further applied to nutritive soil seedling cultivation, manual edible fungi cultivation and base fertilizer, and biogas slurry produced through solid-liquid separation is further applied to disease prevention and increase production through seed soaking, crop foliar fertilizer, crop pest control and integration of water and fertilizer. According to the processing process, the integration of planting and breeding is achieved, pollutants such as the pig excrement and the flushing wastewater of the pig farm are comprehensively utilized, the biogas is recycled, and the biogas residue and the biogas slurry are circularly used, so that the zero release of the biogas slurry is achieved, the economic value is greatly increased, and furthermore, the environmental pollution caused by heavy metal ions is avoided; and a process method is easy, reasonable and easy to implement.
Description
technical field [0001] The invention relates to the field of animal husbandry, in particular to a process for treating pig excrement. Background technique [0002] Animal husbandry is a key industry supported by the state. Improving animal husbandry methods, raising the level of scale, intensification and standardization, and industrializing animal husbandry are the correct ideas for the development of animal husbandry. The output and output value of my country's aquaculture industry have grown rapidly, but there are many problems, such as serious environmental pollution caused by aquaculture, abuse of prohibited feed additives and antibiotics, unfavorable purification and control of epidemics, and low production levels. Affect the sustainable development of the breeding industry and affect the safety of animal food. It is an inevitable requirement for the modernization of my country's animal husbandry industry to study and apply the key technologies of breeding environment ...
