Treating method for organic refuse and special equipment therefor

Abstract

The invention provides a treating method for organic rubbish and a special device thereof. Materials are fully preheated in virtue of over-heated tail gas of a steam boiler or waste gas of a hydrolysis-hydrothermal oxidation reactor; organic materials enter the hydrolysis-hydrothermal oxidation reactor for processing through a feeding machine; the organic materials are processed into deodorizer, liquid fertilizer and organic fertilizer. The treating method of the invention has the advantages of quick treatment speed, thorough sterilization, good quality of the produced fertilizer, no secondary pollution, low operation fee and wide applicable range, and can be broadly applied in the treatment of rubbish such as organic materials in domestic garbage, sewage sludge of sewage plants, agricultural wastes, dead bodies of poultry and live stock, medical wastes and remains of food factories and abattoirs, etc.

Description

technical field [0001] The invention relates to a treatment method and special equipment for organic waste, in particular to a process method for hydrolysis and hydrothermal oxidation treatment of organic matter and a hydrolysis hydrothermal oxidation kettle equipment used in the method. Background technique [0002] At present, domestic municipal solid waste organic matter treatment methods mainly include: 1, landfill method; 2, incineration and incineration power generation method; 3, composting method. Its main features are: [0003] 1. Landfilling method: Landfilling is an extremely passive and impatient garbage disposal method (it can also be called a treatment method without treatment). Although this treatment method has low investment, simple process, and large processing capacity, the landfilled garbage has not been harmlessly treated, let alone resource-based treatment. At the same time, a large number of bacteria and viruses remain, and the seepage of the garbage ...

AI Technical Summary

Problems solved by technology

[0006] (1). It takes a long time for organic matter to pile up and rot, usually three weeks to one month. The accumulation pollution is serious, and flies and mosquitoes breed, which seriously pollutes the surrounding environment and brings great hidden dangers to local sanitation and epidemic prevention.

[0007] (2). The degradation of organic matter is not complete, the treatment is not sufficient, and the residue will still cause garbage pollution

[0008] (3). Organic compost products have many impurities and cannot effectively separate harmful substances such as heavy metals. Long-term use of compost products will cause soil surface deposition, damage soil, and endanger crops

[0009] (4). During the composting process, most of the nitrogen nutrients are naturally released, and phosphorus, potassium and other compounds are naturally degraded, so the quality of the fertilizer is low, and the majority of farmers are unwilling to pay attention to it, and the market prospect is slim
