Description

Technical Field

[0001] The present invention relates to the technical field of manure treatment, and in particular to a rural household-type human and animal manure resource treatment system and method. Background Art

[0002] The impact of manure and sewage discharge on the rural living environment is particularly important. At present, rural manure and sewage discharge in mountainous areas is decentralized and multi-point, and centralized treatment is difficult. Although there are many forms of research on rural manure and sewage discharge, it is difficult to promote systematic application. So far, rural manure and sewage treatment has not been fundamentally solved.

[0003] At present, people discharge kitchen sewage at will, toilet sewage is discharged in an unsystematic manner, and livestock manure is mainly treated manually in scattered piles. This leads to poor sanitary conditions in the living environment and serious secondary pollution of the soil. In mountainous areas with underdeveloped economic conditions, although the rural environment has improved a lot from its original dirty and messy state, there is still a big gap in the construction of rural living environment to meet policy requirements. Therefore, it is necessary to develop a home-based manure resource treatment system that is both applicable and economical.

[0004] At present, the research forms at home and abroad are mainly focused on the discharge of domestic manure and sewage. The specific methods include wetland ecological infiltration, artificial soil filtration treatment, multi-media vertical filtration treatment, etc. In the treatment process, the solid and liquid are not effectively separated. Only people's domestic manure and sewage are treated, and it is not combined with livestock manure for systematic treatment and utilization, resulting in incomplete treatment of suspended matter and gelled solids, which will cause secondary pollution to the environment if discharged directly after treatment. Summary of the invention

[0005] The purpose of the present invention is to provide a rural household human and animal manure resource treatment system and method, aiming to solve the problem that the existing manure treatment system does not effectively separate solids and liquids during the treatment process, only treats people's domestic manure, and does not combine it with livestock manure for systematic treatment and utilization, resulting in incomplete treatment of suspended matter and gelled solids, thereby causing secondary pollution to the environment if directly discharged after treatment.

[0032] First embodiment

[0033] See also Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of the rural household human and animal waste resource treatment system of the first embodiment of the present invention. Figure 2 It is a control principle diagram of the manure transmission equipment 106 of the rural household human and animal manure resource treatment system of the first embodiment of the present invention.

[0034] The present invention provides a rural household human and animal feces resource treatment system: comprising a house 101, feces transmission equipment 106, solid-liquid separation equipment 105, fermentation equipment 102, water spraying equipment 103, water storage equipment and power supply equipment 104, the feces transmission equipment 106 comprises a sewage collection device 107, a human feces collection device 108 and an animal feces collection device 109, the solid-liquid separation equipment 105 comprises a separation net 110, a filter tank 111 and a water outlet pipe 112, and the water storage equipment comprises a water storage tank 113 and a filter net 114.

[0035] In this embodiment, the feces and sewage are collected by the feces and sewage transmission equipment 106, and the collected feces and sewage are transmitted to the solid-liquid separation equipment 105, so that the solid-liquid separation equipment 105 can perform solid-liquid separation on the solids and liquids in the feces and sewage, and after the solid-liquid separation, the separated solids are transmitted to the baking and fermentation equipment 102 for fermentation, and the separated liquids are purified by the purification equipment and discharged for irrigation, so as to realize the comprehensive utilization of solids and liquids. Afterwards, the water spraying equipment 103 is powered by the power supply equipment 104, and the water source stored in the water storage equipment is transmitted to the water spraying equipment 103, and finally sprayed out from the water spraying equipment 103, so as to realize the full-automatic cleaning of the solid-liquid separation equipment 105. In the whole process of processing the feces and sewage resources, the solids and liquids in the feces and sewage can be effectively separated, so that the suspended matter and the gelled solids can be thoroughly processed, thereby avoiding the situation that the direct discharge of the solids and liquids that are not effectively separated will cause secondary pollution to the environment.

[0036] Among them, the manure transmission equipment 106, the solid-liquid separation equipment 105, the baking and fermentation equipment 102 and the automatic water spray cleaning equipment 103 are all arranged in the house 101, the power supply equipment 104 is installed on the sloping roof of the house 101, and the water storage equipment is arranged outside the house 101; the manure transmission equipment 106 is used to collect manure and sewage, and transmit the collected manure and sewage to the solid-liquid separation equipment 105; the solid-liquid separation equipment 105 is used to perform solid-liquid separation on solids and liquids in manure and sewage; the baking and fermentation equipment 102 is used to bake and ferment the separated solids to achieve the reuse of the solids; the automatic water spray cleaning equipment 103 is used to clean the residue filtered out of the solid-liquid separation equipment 105; the water storage equipment is used to supply water to the water spray equipment 103 and drinking water for livestock; the power supply equipment 104 is used to supply power to the operation of the automatic water spray cleaning equipment 103 and the baking and fermentation equipment 102.

[0037] Secondly, the sewage collection device 107, the human feces collection device 108 and the animal feces collection device 109 are used to collect kitchen sewage, human feces and animal feces respectively. The sewage collection device 107 and the human feces collection device 108 collect and drain the sewage through the centralized sewage pipe 115 to the solid-liquid separation equipment 105 for solid-liquid separation. The animal feces collection device 109 directly enters the solid-liquid separation equipment 105 for solid-liquid separation by sweeping or self-falling.

[0038] Again, the purification pool 111 is arranged below the separation net 110, the outlet pipe 112 is connected to the purification pool 111, and passes through the house 101 and extends to the outside of the house 101. The purification pool 111 is a multi-format step-by-step filtering connected filter pool 111. The filter pool 111 is waterproofed all around to avoid secondary soil pollution caused by liquid leakage.
