Abstract

The invention discloses an aerobic fermentation fertilizer making device for organic solid waste, which comprises fermentation cabins, a plant, multifunctional pile turning machines, a feeding device and a screening machine, wherein multiple groups of fermentation cabins are arranged in the plant; each group of fermentation cabin comprises a primary fermentation cabin and a secondary fermentation cabin which are correspondingly arranged on an upper position and a lower position; the bottoms of the two fermentation cabins are respectively provided with a transmission belt, an idler wheel and an aeration pipe; the discharging end of the feeding device is positioned on the primary fermentation cabin; the multifunctional pile turning machines are arranged in the two fermentation cabins; the bottoms of the two fermentation cabins are respectively provided with a movable baffle; one end of the transmission belt of each fermentation cabin corresponds to the position of the movable baffle of the fermentation cabin; the outlet of the movable baffle of the primary fermentation cabin is positioned above the transmission belt of the secondary fermentation cabin; the outlet of the movable baffle of the secondary fermentation cabin is positioned above the screening machine; the top of the plant is provided with an odor centralizing pipe provided with a plurality of air inlets; and the odor centralizing pipe is connected with a deodorization device arranged out of the plant. The aerobic fermentation fertilizer making device for the organic solid waste has the advantages of small occupied land, high mechanized degree and low operation cost and is simple to operate.

Description

technical field [0001] The invention relates to the technical field of garbage resource treatment and utilization, in particular to a device for making fertilizer by aerobic fermentation of organic solid waste, and also relates to a method for making fertilizer by aerobic fermentation of organic solid waste. Background technique [0002] Organic solid waste generally includes municipal sludge, urban garbage, poultry manure, food waste, etc. After these solid wastes are discarded after losing their original use value, due to their high water content, they also contain organic matter, nitrogen, phosphorus, heavy metals and Salts, pathogenic microorganisms and parasite eggs are perishable and emit a strong odor. If they are not treated effectively, they will not only damage the environment, pollute the soil, water, and atmosphere, affect environmental sanitation, endanger human health, but also invade land. The treatment and disposal of organic solid waste such as urban sludge...
