Ecological integrated treatment method for rural excrement recovery

Abstract

The invention discloses an ecological integrated treatment method for rural excrement recovery. The method comprises the following steps: (1) collecting excrement from each household in rural areas and centralizing the excrement to a village-level public toilet transformed into a standardized treatment substation; (2) carrying out solid-liquid separation in the treatment substation, carrying out liquid flocculation on the separated liquid, carrying out excrement biochemical conversion on the separated solid and the precipitate of the liquid flocculation, carrying out excrement biochemical conversion through biological treatment, and purifying and discharging the liquid subjected to flocculation treatment; (3) gathering the solid products subjected to biochemical conversion into a total treatment center for processing into feed additives and organic fertilizer products, and purifying and discharging liquid products; and (4) carrying out seed insect culture and functional strain culturerequired by biological treatment in the total treatment center. The excrement and sewage ecological integrated scheme is a toilet revolution called as a rural pit toilet, the problem of environmentalpollution can be solved, resources can be fully utilized, an existing waste treatment mode is effectively changed, and sustainable utilization of the resources is achieved.

Description

technical field [0001] The invention relates to a method for treating manure in rural toilets, belonging to the field of ecological environment. Background technique [0002] In today's increasingly developed modern economy, in addition to material needs, people are increasingly pursuing a state of harmonious coexistence between people and nature, but environmental pollution and ecological destruction have broken this harmony and balance. In addition to industrial production, which is recognized as the largest source of pollution, the proportion of human domestic waste and feces pollution is increasing year by year. If effective measures are not taken for comprehensive treatment, it will directly cause the deterioration of human living space. [0003] Especially in the rural environment, due to the limited economic level and conditions, whether it is a family or a public toilet, dry toilets are still the main one at present. Take a typical Beijing suburban town as an example...

AI Technical Summary

Problems solved by technology

[0004] However, at present, the treatment of toilets and breeding manure is only the development of individual technologies, and there is no systematically feasible solution for the actual rural environment. The efficiency and benefits are low. Due to the impact of freezing, the treatment scale is limited; and the biogas conversion, which has been a key development for many years, has complicated technology, and the product is flammable and unsafe, which is not conducive to promotion

Therefore, there is currently no way to form a scalable and sustainable industrial chain
