Embodiment 1

[0008] Embodiment 1, firstly, by sorting and screening raw domestic garbage, sort out recyclable waste items including paper, plastics, and heavy metals for recycling, and sort out combustible items including plants and waste clothes and send them to the burner for burning; Then, the remaining garbage is crushed and sieved once or twice, and then classified and added with active bacteria, stirred evenly, and then transported to a high-temperature fermenter for fermentation to make organic fertilizer nutrient soil. The present invention can use combustible materials such as sorted plants, firewood and waste clothes to burn in the burner to heat the high-temperature fermentation machine, so as to make full use of resources and process waste. It is best to use a closed fermentation tank for high-temperature fermentation machines to avoid polluting the surrounding air. The active bacteria can be high-temperature fermentation bacteria, HB bacteria and the like. The invention can c...

Embodiment 2

[0012] Example 2, first put raw 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%, it is necessary to add sepiolite clay mineral powder to adjust the humidity , heat up to 80-95°C, if the temperature is controlled at 90°C, sterilize for three hours, then cool down to 60-75°C, such as about 70°C, add HB strains for aerobic fermentation for 18-32 hours, such as 24 hours Left or right, the purpose of complete fermentation can be achieved, the fermentation process is ended, and the material can be bagged after cooling. . All the other are with embodiment 1.

Embodiment 3

[0013] 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 , add HB strains to carry out aerobic fermentation for 18-32 hours, and pack the material after cooling. All the other are the same as above-mentioned embodiment.

Abstract

The invention discloses a harmless treatment technology for household garbage. The harmless treatment technology mainly solves the technical problems that an existing household garbage treatment method is not environment-friendly and the like. According to the technical scheme of the harmless treatment technology, firstly, a raw material of the household garbage is sorted and screened, recyclable waste articles such as paper, plastic and heavy metal are sorted out and recycled, a combustible such as plants and waste clothes are sorted out and are conveyed to a combustor to be combusted; and then the rest of the garbage is crushed and screened and then is classified, active bacteria are added into the classified garbage, and the active bacteria and the classified garbage are uniformly stirred and then are conveyed to a high-temperature fermentation machine to be fermented so as to prepare organic fertilizer nutrient soil. The harmless treatment technology has the advantages that the whole process that the household garbage is fermented, decomposed, deodorized, sterilized, purified, concentrated and discharged only needs 18-30 hours, the volume of the garbage can be decreased by about 30-70%, and a high-quality organic fertilizer with excellent color, smell and nutrients and a nutritional type organic matrix can be produced; and the harmless treatment technology is energy-saving and environment-friendly and can be widely applied to treatment and reutilization of the household garbage.

Description

technical field [0001] The invention relates to a treatment process of domestic garbage, in particular to a process for harmless treatment and comprehensive recycling of domestic garbage. Background technique [0002] At present, traditionally, domestic waste is generally only piled up for a long time in the yard for natural decomposition, resulting in stench, attracting flies and insects flying all over the sky, fermentation takes 30-90 days, and is easily affected by the weather, resulting in cross-flow of sewage , resulting in secondary pollution. Moreover, a large storage yard is required, and the organic matter cannot be effectively recycled, resulting in a waste of resources. Contents of the invention [0003] The object of the present invention is to provide a comprehensive utilization process for the harmless treatment of household garbage with fast processing speed, energy saving and environmental protection. [0004] The technical solution adopted by the presen...
