Embodiment 1

[0010] Example 1: First, by sorting and screening raw domestic waste, recyclable waste items including paper, plastic and heavy metals are sorted out for recycling, and combustibles including plants and waste clothes are sorted out and sent to burners for combustion; Then, the remaining garbage is crushed and sieved more than once or twice, and then the active bacteria are added into the classification and stirred evenly, and then sent to the high-temperature fermentation machine to be fermented to make organic fertilizer nutrient soil. The present invention can utilize the heat energy generated by burning combustibles such as plants, firewood and waste clothes in the burner to heat the high temperature fermentation machine, so as to fully utilize the resources and dispose of the waste. The high temperature fermentation machine is best to use a closed fermentation tank to avoid pollution to the surrounding air. The active bacteria can be high temperature fermentation bacteria,...

Embodiment 2

[0014] Example 2, first put the raw material domestic waste including organic waste feces and residues into the fermentation tank. If the moisture is relatively high, such as when the moisture content is close to but not more than 40%, sepiolite clay mineral powder needs to be added to adjust the humidity. , heating up to 80-95 ℃, such as controlling the temperature at 90 ℃, sterilizing for three hours, then cooling to 60-75 ℃, such as about 70 ℃, adding HB strains for aerobic fermentation for 18-32 hours, such as 24 hours The purpose of complete fermentation can be achieved, the fermentation process is ended, and the material can be bagged after cooling. See Figures 1 and 2. The rest are the same as in Example 1.

Embodiment 3

[0015] Example 3, first put raw domestic waste including organic waste feces and residues into the fermentation tank, add plant straw powder or sawdust, heat up to 80-95 ° C, sterilize for three hours, and then cool down to 6-75 ° C , adding HB strains to carry out aerobic fermentation for 18-32 hours, and the material can be bagged after cooling. See Figures 1 and 2. The rest are the same as the above-mentioned embodiment.

Abstract

A harmless processing comprehensive utilization technology for life garbage is mainly used for solving the technical problems such as non-environmental protection of prior life garbage processing manner. The technical proposal mainly comprises the following steps of: separating and screening raw life garbage to separate recyclable waste materials such as paper, plastic and heavy metals for recycling and reusing, and combustible materials such as plants and waste clothes for burning in a burner; and then crushing the rest garbage, sieving, sorting, adding active bacteria, stirring completely, feeding into a high-temperature fermenter, and fermenting to obtain organic fertilizer and nutrient soil. According to the invention, the full process for processing the life garbage including fermenting, decomposition, deodorization, sterilization, purification, concentration and discharge only takes 18 to 30 hours, the volume of the waste materials can be reduced by about 30% to 70%, and high-quality organic fertilizer and nutrient organic substrate excellent in color, odor and nutrient can be produced. The process is energy-saving and environment-friendly, and can be widely used to process and reuse the life garbage.

Description

technical field [0001] The invention relates to a process for treating domestic garbage, in particular to a process for harmlessly treating and comprehensively recycling domestic garbage. Background technique [0002] At present, traditionally, domestic garbage is usually only piled up in the yard for a long time to make it decompose naturally, resulting in a foul odor, attracting flies and insects flying all over the sky, and fermentation takes 30-90 days, which is easily affected by weather and causes cross-flow of sewage. , resulting in secondary pollution. In addition, it requires a large storage yard, and organic matter cannot be effectively recycled, resulting in waste of resources. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a comprehensive utilization process for the harmless treatment of domestic waste with fast processing speed, energy saving and environmental protection. [0004] The technical scheme adopted by the pres...
