Embodiment Construction

[0015] (1) Crush the mixture of paper, fiber, bamboo wood, kitchen vegetable residue, fruit peel, and garden garbage in the household garbage. The particle size after crushing is 0.3mm~1.5mm, and the weight percentage of the particle is added. It is 55% domestic sewage treatment plant sludge. After 9 days of mixed acidification treatment, material A is formed; anaerobic granular sludge is added according to the weight percentage of material A as 25%, and water is added at 12% for mixing. Oxygen fermentation is highly efficient conversion treatment to produce biogas, biogas liquid and material A biogas residue.

[0016] (2) In the biogas residue of material A, add the weight percentage of biogas residue of material A in order: 25% calcium carbide residue, 25% dolomite powder, 30% fly ash, and 20% calcium cyanamide. After mixing and maturation, material B is formed, which is used for acid soil restoration.

[0017] (3) Stir, mix and crush agricultural straws and forestry wastes to 0...

Abstract

The invention discloses an organic solid waste integrated ecological resource utilization technical method, and belongs to the field of environmental protection engineering. The method is characterized in that various different organic solid wastes are added to auxiliary materials at different stages, and ordered mixing, fermentation and conversion are carried out to form various resource products. The products can be used for acid land remediation and can form ecological organic fertilizers. The method breaks through the traditional thinking, and on the basis of paying attention to fertilizerquality, fermentation is accelerated to increase the conversion rate, and integrated production is carried out in stages; and by using the alkalization effect of the auxiliary materials and the enzyme digestion effect of the biological enzyme, substances containing high fibers, lignin and the like are degraded and converted into polysaccharides, bioactive organic acids and other element substances so as to achieve the purposes of crop growth promoting, crop disease resistance enhancing and crop nutrient absorption capacity improving.

Description

Technical field [0001] The invention belongs to the technical field of organic solid waste integrated treatment and resource utilization, and specifically relates to a technical method for integrated ecological resource utilization of organic solid waste. Background technique [0002] According to statistics, my country currently discharges more than 4 billion tons of organic solid waste each year. These large amounts of organic solid waste are hoarded and piled up around urban and rural areas, not only occupying a large amount of land resources, but also causing serious environmental pollution. How to deal with these organic solid wastes and how to make these organic solid wastes resources has become an important topic in the modernization of cities and towns. In our country, due to the constraints of technology and many other factors, most of these organic solid wastes have not been centralized factory, large-scale environmental protection treatment and resource utilization.
