Embodiment Construction

[0005] A kind of high-temperature aerobic fermentation process of organic waste of the present invention is as follows:

[0006] Organic waste is processed by a hydraulic pulverizer, which can pulverize biodegradable substances into a homogenate and use it as a raw material for biological fermentation. Because it is under hydraulic conditions, not only can the bio-organic matter be made into a homogenate, but also some stones, sediment, glass, metal, etc. removed from the surface. Wet sorting not only has high sorting efficiency, but also produces no dust and has little environmental pollution. Hydraulic pulverization can more thoroughly sort the sundries in organic waste. After the homogenate treated by the hydraulic pulverizer, the process parameters are adjusted at the same time, so that the pH is between 6-9, the C / N is between 12:1-30:1, and the solid content is controlled at about 6-12%; then enter In the primary fermentation tank, the temperature of the slurry in the ...

Abstract

A high-temperature aerobic fermentation of organic waste and its apparatus are disclosed. The process is carried out by using thermophile, breaking biodegradable substances in organic waste as raw materials, entering broken materials into primary fermenter, lifting temperature and inoculating, supplying aeration, entering materials into secondary fermenter, supplying aeration, adding ferment additive, intensified fermenting, entering materials into grate to separate varia, solid-liquid separating, forming filter cake, processing filter cake into solid fertilizer, and processing filtrate into liquid fertilizer. It has short time and can be used for food refuse and urban mud.

Description

technical field [0001] This application relates to organic waste treatment process and equipment. Background technique [0002] The main component of municipal solid waste is organic matter. Organic matter and high moisture are the most troublesome problems of traditional treatment methods (landfill, incineration, etc.), and are also the main reasons for the high input and low output of traditional treatment methods. At present, the main technology for biological treatment of organic waste in the world is composting, which is divided into aerobic composting and anaerobic composting. At present, the common problems in the composting process are: the decomposition rate of organic matter is slow, the processing process is long; the floor area is large; the effect of removing pathogenic bacteria is poor; The market value of the end product is low. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provides a high-tempe...
