Embodiment Construction

[0064] Such as Figure 1-6 As shown, a method for constructing an urban vein industrial park system includes the following steps:

[0065] A), garbage sorting

[0066] Sorting municipal solid waste, the municipal solid waste includes biomass waste and fossil waste, the biomass waste includes kitchen waste, garden waste, straw, expired food, dead animals, sludge, etc.; the fossil waste Classified waste includes plastic products, metal, glass, construction concrete, etc.; sort out construction waste and old household appliances from the municipal solid waste.

[0067] B), biomass separation treatment

[0068] After the municipal solid waste sorted by step A) is broken into bags and separated from dryness and wetness under 80Ma-100Mpa high-pressure backlog, dry garbage and wet garbage are formed.

[0069] C), urban waste energy conversion

[0070] C1), the wet garbage and sludge in step B) are anaerobically digested to form biogas, nitrogen-containing filtrate and biocarbon s...

Abstract

The invention discloses a construction method of an urban venous industry park system. The construction method comprises the steps of garbage sorting: sorting urban household garbage composed of biomass garbage and fossil garbage, and sorting construction garbage and old household electrical appliances out of household garbage; biomass separation treatment: carrying out bag breaking and dry-wet separation on the sorted household garbage, so as to form dry garbage and wet garbage; and garbage energy conversion: carrying out anaerobic digestion on wet garbage and sludge to form biogas, nitrogen-containing filtrate and biological carbon soil, purifying biogas to form natural gas, purifying the nitrogen-containing filtrate through a nitrogen-containing digestion liquid to form recycled water and biological carbon soil, utilizing recycled water and biological carbon soil to cultivate trees in pots, breaking, disassembling and sorting / separating construction garbage, the old household electrical appliances and dry garbage to obtain renewable energy and renewable materials, and preparing renewable energy into fuel through garbage derived fuel. According to the construction method, the close-loop mode of resources-products-renewable resources is achieved, and household and industrial garbage is changed into treasure and is circularly utilized.

Description

technical field [0001] The invention relates to a method for treating urban domestic garbage, in particular to a method for constructing an urban venous industrial park system. Background technique [0002] my country's urban waste treatment lacks top-level research, lacks in-depth research on the origin of waste generation and corresponding classification methods, and lacks theoretical guidance in the practice of waste classification collection, treatment and disposal, which leads to low levels of waste treatment efficiency and benefits. Due to the lack of top-level theoretical guidance, the technical research and development and application of urban waste treatment in my country have unclear footholds and starting points, and the fundamental goal is unclear. They often rely on achievable and single "harmless" treatment technologies to dominate the process route of waste treatment. To a certain extent, it deviates from the direction and principle of "resources". There is no...
