Description

Wet garbage comprehensive treatment system
Technical Field

Background
China is a big agricultural country, and the comprehensive utilization of straws is mainly five-purpose, namely straw fertilization, straw feed, straw energy regeneration, straw raw material conversion and straw base material conversion. According to statistics, the theoretical resource amount of the straws in China in 2017 is 8.84 hundred million tons, and the theoretical resource amount of the straws in China in 2018 reaches about 8.86 hundred million tons, and incineration and waste become main treatment modes, so that not only is environmental pollution caused, but also serious resource waste is brought. Therefore, the comprehensive utilization rate of the crop straws is imperatively improved. The straw fertilization is mainly realized by returning straws to the field, the straws can supplement and balance nutrients in soil after returning to the field, the organic matter content of the soil is increased (0.01%/year), the soil fertility is improved, the granular structure of the soil is improved, the aims of reducing the fertilizer consumption and increasing the yield (the average yield per mu is increased by more than 10%) are further fulfilled, and the method is an effective measure for improving the production potential of crops. Returning the straws to the field can be divided into direct returning, indirect returning and biochemical decomposition returning. The pests are easy to breed when the fertilizer is directly returned to the field, and the soil moisture content has certain influence to influence the rate of emergence of the seeds. Therefore, the straw biochemical decomposition and returning to the field is one of the more effective methods in the present.
The kitchen waste is mainly from waste cooked or eaten by residents in daily life, and compared with food waste, the kitchen waste is low in yield, stable in components and single in source. Landfill is the most common domestic garbage treatment method, has many defects, can generate toxic and harmful gases and heavy metals to pollute soil, environment and atmosphere, is difficult to transport, has high operation cost, and has complex subsequent treatment process of leachate, so the landfill method is increasingly not accepted. The chemical property of the kitchen waste can not be changed by direct crushing, the operation is convenient, the operation is simple, the cost is low, and the kitchen waste can be directly transferred into a sewage treatment system without special treatment. However, when the kitchen waste is discharged into a sewer, bacteria are easily bred, odor is generated, disease transmission is caused, and the methane gas generated by the kitchen waste crushed aggregates in the drainage pipeline has serious potential safety hazard. The techniques for converting kitchen waste into feed include a high-temperature sterilization method and a biological treatment method, but the homology does not suggest the use of kitchen waste as an animal feed. The kitchen waste can produce a large amount of odorous substances such as hydrogen sulfide, methyl mercaptan, methyl sulfide and the like and percolate by independently composting, and the pollution is serious.
The wet garbage mainly refers to kitchen garbage, straw waste and vegetable waste. The existing wet garbage treatment technology generally adopts a biological fermentation machine directly, and has the advantages of power consumption and high cost. The wet garbage enters a biological fermentation machine, is intermittently stirred, is added with microbial strains to accelerate the fermentation speed, is generally fermented for 24 hours to generate liquid, gas and residues, the liquid enters a sewage treatment plant after being treated by a sewage pipe network, and the gas enters a purification device. According to the actual use condition, the electricity consumption for processing 1t of garbage is about 130-.
