Problems solved by technology

In the drying + incineration scheme, the drying and incineration process can completely carbonize the organic matter and reduce the sludge volume to the greatest extent. The main problems of the incineration method are large one-time investment, high equipment cost, relatively low calorific value of sludge, and reduced furnace capacity. internal temperature, high operating costs, and even the heavy metals and some toxic and harmful substances contained in the slag and flue gas produced during the incineration process may form secondary pollution
How to deal with organic solid waste based on a more ecological method that does not require a large amount of investment, there is currently no more in-depth research

preparation example Construction

[0036] The present invention also provides a method for preparing the above-mentioned organic material, which includes the following steps: after the plant is harvested and the straw is removed, the remaining material is pulverized to obtain the organic material.

[0037] In the present invention, the plant is preferably a fibrous root system. The fibrous root is slender and fragile, which does not affect the subsequent processing and utilization of the treated product; and when the average humidity of the material is gradually reduced to about 45%, the material will gradually reduce the effect on earthworms. Water and nutrient supply, most earthworms will gradually die and be decomposed by microorganisms in the final stage of treatment, so there is no need to treat earthworms.

[0038] The present invention also provides the application of the above-mentioned organic material as a seedling substrate.

[0039] The organic material of the present invention can also be used as a...

Embodiment 1

[0042] Time: From August 27, 2021 to November 8, 2021.

[0043] Location: Xiantao City, Hubei Province

[0044] Disposed organic solid waste: 5 tons of dehydrated activated sludge from Xiantao Chengxi Sewage Treatment Plant, humidity 78% according to figure 1 to operate in the mode shown:

[0045] 1. Tightly wrap the water-proof sleeve on the bottom of the root controller and fix it. The water-proof bag is made of rain-proof plastic cloth, and the root controller adopts a conventional gardening root controller with a width of 1m to form a cylinder with a diameter of 1m.

[0046] 2. Use earthworm soil with a humidity of about 45% and domestic sludge with a humidity of 78% to adjust the humidity and structure. The earthworm adaptability test was carried out on the mixture. When the volume ratio of earthworm soil to sludge was 1:3, earthworms could enter quickly and not come back. The mixture humidity was about 73% at this point.

[0047] 3. Put the adjusted earthworm soil a...

Abstract

The invention provides an ecological treatment method of organic solid waste and an obtained organic material, and relates to the technical field of garbage treatment. According to the invention, plants, humus soil and earthworms are utilized to co-treat organic solid wastes, compared with high-temperature compost, the investment and operation cost is lower, and compared with the single fertilizer application direction of high-temperature compost products at present, the organic materials produced by the ecological treatment method can be used as fertilizers and also can be used as organic fertilizers. The method has a more unique effect in the field of matrix application, and better meets the requirements of modern agricultural soilless culture and matrix culture. Compared with earthworm compost, the ecological treatment method disclosed by the invention has the advantages that the decomposition humification degree is higher, the requirement of an operation link on the environment is lower, the degradation process of perishable organic solid wastes is also a natural drying and dehydration process, the bottleneck that the earthworm cast is difficult to naturally dry is broken through, the treatment process is more environment-friendly, and a final product is easier to commercialize.

Description

technical field [0001] The invention belongs to the technical field of garbage disposal, and in particular relates to an ecological treatment method of organic solid waste and the obtained organic material. Background technique [0002] With the rapid development of urbanization in my country, the total amount of organic solid waste produced in cities in my country has been rising steadily. In the foreseeable future, the total amount of urban organic solid waste will continue to rise. However, for the treatment methods of organic solid waste, there are mainly thermal hydrolysis + anaerobic digestion technology, and drying + incineration solutions. Among them, the thermal hydrolysis + anaerobic digestion technology first sorts the domestic waste out of the wet waste and mixes it with municipal sludge to pulverize it to make primary pulp. After pretreatment by storage tank thermal hydrolysis, anaerobic digestion is carried out to generate biogas, which is used for power generat...
