Description

technical field

[0001] The invention relates to the technical field of aquaculture waste treatment, in particular to a multifunctional livestock and poultry manure energy pretreatment composite system. Background technique

[0002] Based on various biomass resources all over the rural areas, on-site and nearby resource utilization, the development of biomass energy is an inevitable requirement for the comprehensive realization of national energy transformation. Reduce air pollution and fossil energy consumption. According to the requirements of new rural construction and the strengthening of people's awareness of environmental protection and energy conservation, with the development of animal husbandry, the discharge of livestock waste is increasing, and the negative impact on the agricultural ecological environment, water and soil environment is also becoming more and more serious.

[0003] Livestock and poultry manure is mainly a mixture of excrement from livestock and po...

Examples

Embodiment 1

[0050] Such as figure 1 As shown, the present invention provides a multifunctional livestock and poultry manure energy pretreatment composite system, including anaerobic fermentation system, solid-liquid separation system, biogas recovery and utilization system and organic fertilizer utilization system.

[0051] Described anaerobic fermentation system comprises anaerobic fermentation tank 1 and aerated fermentation device 2; Described aerated fermented device comprises fan blade 202, soft belt 201, bubbling reactor 204 and first eccentric wheel 203, as figure 2 As shown, the first eccentric wheel 203 drives the fan blade 202 to rotate to inject air into the soft belt 201; a baffle 204A is arranged in the middle of the bubble reactor 204, and a gas distributor is arranged in the middle of the bottom 204B.

[0052] The manure discharged from the livestock and poultry house 13 flows through the manure tank 14, and then enters the anaerobic fermentation tank 1 from the manure ta...
