Abstract

The invention discloses a distributed rural domestic waste recycling device and an application thereof. The device comprises a waste pretreatment system, a sewage anaerobic fermentation tank and a sewage secondary treatment tank, wherein the waste pretreatment system comprises a household garbage can, a stirring system, an organic garbage decomposition tank and an inorganic garbage storage tank. Compared with the prior art, the distributed rural domestic waste recycling device and the application thereof have the characteristics of wide adaptation to fermentation raw materials, less one-time investment, simplicity and convenience in operation, low operation and management cost, capability of recycling part of clean energy resources, and the like, so that the source reduction of the household garbage is realized, the household garbage reduction rate is over 40%, the collection and transportation cost of the household garbage is greatly lowered, the on-the-spot disposal and the reclamation of the domestic sewage are realized, too many pipelines are not needed to be laid, the needs of distributed rural domestic waste treatment, low investment and low maintenance cost are met, and the popularization and utilization value is very good.

Description

technical field [0001] The invention belongs to the field of resource recycling and environmental protection, and in particular relates to a distributed rural domestic waste recycling device and its application. Background technique [0002] In recent years, due to the rapid development of social economy and the improvement of people's living standards, the amount of domestic waste has increased accordingly, but the environmental protection awareness, living habits and supporting environmental protection facilities of rural residents have not followed up, and rural domestic sewage is directly discharged into Rivers and domestic garbage are directly discarded around the courtyard or nearby ditches. Domestic sewage and domestic garbage pollution from rural life has become an important source of rural non-point source pollution, and the rural ecological environment is gradually deteriorating. As governments at all levels pay more and more attention to environmental protection, ...
