Problems solved by technology

Among them, the process of composting fermentation to treat urban domestic waste is simple, suitable for waste treatment with high organic matter content, and can produce organic fertilizers, but the organic matter content of compost is low, and the quality of fertilizers is poor. Organic fertilizers processed from decomposed waste affect the scope of application of fertilizers.
In addition, most composting sites use natural ventilation or mechanical ventilation for aerobic fermentation, so the waste gas generated cannot be treated and the fermentation time is long

Embodiment Construction

[0060] The method of the present invention will be further described in detail below in conjunction with specific examples.

[0061] (1) Using 6 strains of cellulolytic bacteria with strong enzyme activity independently isolated and screened out, organically compounding with isolated and preserved beneficial bacteria such as Bacillus subtilis, phosphorus bacteria, silicate bacteria, lactic acid bacteria and actinomycetes, developed One kind of biological compound bacterial agent was produced.

[0062] (2) Through cost-effective analysis, optimize and screen out better bio-organic fertilizer raw materials, which are organic materials such as garbage, peat, rice husk powder, sawdust, weathered coal, and mushroom production waste; the ratio of raw materials for producing bio-organic fertilizer is as follows: Garbage 45%, peat 35%, rice husk powder 13%, weathered coal 5%, rice bran 1.5% and biological bacteria agent 0.5%.

[0063] (3) Carry out research on waste purification trea...

Abstract

The invention discloses a technology for preparing bio-fertilizer from garbage. The technology provided by the invention adopts raw materials of 45% of garbage, 35% of turf, 13% of rice husk powder, 5% of danty, 1.5% of rice bran and 0.5% of a composite microbial inoculant, and comprises carrying out composting through uniformly mixing the crushed garbage, the crushed turf, the crushed rice bran and the crushed danty to obtain mixed raw materials, carrying out micropropagation of the composite microbial inoculant which is a home-made composite microbial inoculant, uniformly mixing the composite microbial inoculant subjected to micropropagation and the mixed raw materials, and piling up the mixture by a turning ventilation method so that the mixture forms a pile having the length of 5m, the width of 4m and the height of 1.5m. The technology provided by the invention selects a novel strain, utilizes novel inoculants, optimizes production processes, realizes preparation of organic bio-fertilizer satisfying the national standard through selection of a raw material ratio, confirms field application effects of the organic bio-fertilizer, lays a firm foundation for popularization of the organic bio-fertilizer and wide application of the organic bio-fertilizer in production, and is suitable for the technical field of environmental protection.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a bio-fertilizer process from garbage. Background technique [0002] At present, the methods adopted for waste disposal mainly include landfill, composting, and incineration. Among them, the process of composting fermentation to treat urban domestic waste is simple, suitable for waste treatment with high organic matter content, and can produce organic fertilizers, but the organic matter content of compost is low, and the quality of fertilizers is poor. Organic fertilizers processed from decomposed waste affect the scope of application of fertilizers. . In addition, most composting sites use natural ventilation or mechanical ventilation for aerobic fermentation. Therefore, the waste gas generated cannot be treated and the fermentation time is long. Contents of the invention [0003] The purpose of the present invention is to overcome the above-ment...
