Problems solved by technology

However, conventional high-temperature fermentation requires the addition of high-temperature bacteria in each fermentation process. Due to the high processing cost of high-temperature bacteria, high-temperature aerobic fermentation is not suitable for implementation in rural areas.

Embodiment 1

[0054] The method for processing rural multi-source organic solid waste provided in this embodiment includes the following steps:

[0055] Step S1, mix chicken manure, milk powder, and rice husk according to the mass ratio of 1:0.5:1, wherein the moisture content of chicken manure is 80%, the moisture content of milk powder is 15%, and the moisture content of rice husk is 15%, to obtain high temperature The mixture of domesticated bacteria, the carbon-nitrogen ratio of the domesticated mixture of high-temperature bacteria is 15:1, and the water content of the mixture of domesticated high-temperature bacteria is 40%. Acclimate the high-temperature bacteria acclimation mixture at 80°C for 2 hours, and the bacterial population density after acclimatization is ≥1×10 9 per g, meet the requirements of bacterial population density, and obtain the finished product of high-temperature bacteria domestication.

[0056] Step S2, mixing human feces to be treated, finished products domesti...

Embodiment 2

[0061] Step S1, mix chicken manure, milk powder, and rice husk according to the mass ratio of 1:0.5:1, wherein the moisture content of chicken manure is 80%, the moisture content of milk powder is 15%, and the moisture content of rice husk is 15%, to obtain high temperature Bacteria acclimatization mixture, the carbon-nitrogen ratio of the high-temperature bacteria-acclimation mixture is 12:1, and the moisture content of the high-temperature bacteria-acclimation mixture is 40%. Acclimate the high-temperature bacteria acclimation mixture at 80°C for 2 hours, and the bacterial population density after acclimatization is ≥1×10 9 per g, meet the requirements of bacterial population density, and obtain the finished product of high-temperature bacteria domestication.

[0062] Step S2. Mix human feces to be treated, finished products domesticated by high-temperature bacteria, and rice husks at a mass ratio of 4:1:1, wherein the moisture content of human feces to be treated is 62%, an...

Abstract

The invention provides a method for treating rural multi-source organic solid waste. The method comprises the following steps of: S1, mixing chicken manure, milk powder and a carbon-nitrogen ratio supplement to obtain a thermophilic bacteria domestication mixture, and domesticating the thermophilic bacteria domestication mixture at 65-80 DEG C until the thermophilic bacteria domestication mixture reaches the flora density requirement to obtain a thermophilic bacteria domestication finished product; and S2, mixing human excrement to be treated, the thermophilic bacteria domestication finished product and the carbon-nitrogen ratio supplement to obtain a stack, and fermenting the stack to prepare an organic fertilizer. The method has the advantages of short treatment period, high fermentation temperature and high harmless degree of products, and the treatment cost of the method is low and controllable.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, in particular to a method for treating multi-source organic solid waste in rural areas. Background technique [0002] Rural areas are an important source of organic solid waste. Rural organic solid waste includes human feces, livestock and poultry manure, agricultural waste, and domestic garbage. At present, dry toilets are mostly used in rural areas. If the human excrement produced is not treated in time, on the one hand, it will breed insects and flies, infect diseases, and affect the perception; on the other hand, it will pollute the soil, groundwater, atmosphere and other environmental subjects; As far as domestic waste is concerned, it also has the characteristics of environmental pollution. At present, farmers mostly use the traditional retting method for livestock and poultry manure and human manure, which often needs to be carried out throughout the winter, which takes a lo...
