Abstract

The invention discloses an extraction and refining process of perishable organic matters in garbage. The process comprises the steps that mixed garbage with the particle size of 200mm or below is impacted and crushed, RDF is separated from the fine crushed mixed garbage by utilizing the characteristic of the RDF as a soft material, then perishable organic matters containing fine crushed slurry isobtained, jugging separation is carried out after RDF washing water and circulating process water are added to adjust the solid content of the slurry, inorganic particulate matters, sediment and residual fine crushed RDF in the slurry are separated, finally the perishable organic matters containing fine crushed slurry is filter pressed into an organic matter filter cake, the moisture content of the filter cake is controlled to be in the optimal range of aerobic fermentation of the organic matter filter cake, then the aerobic fermentation treatment is carried out on the organic matter filter cake, and filtrate is recycled and not discharged after the treatment. According to the extraction and refining process of the perishable organic matters in the garbage, the perishable organic matters are separated from the soft RDF by utilizing the characteristics of low strength and easy impact and crushing of the perishable organic matters, perishable organic matters with high purity, small particles, stable moisture and controllable pollutants are obtained through refining, and channels are opened for resource utilization of the perishable organic matters in the garbage.

Description

Technical field: [0001] The invention relates to the technical field of garbage treatment, in particular to a process for extracting and refining perishable organic matter in garbage. Background technique: [0002] In the waste comprehensive resource disposal technology, the fine classification and sorting of waste is the most critical step. Without fine sorting and sorting of garbage, refined RDF with low moisture content, low ash content, metal and inorganic particles cannot be obtained, and the yield and quality of the main pyrolysis products of RDF (pyrolysis oil and pyrolysis carbon) are difficult to guarantee . Without fine sorting and sorting of garbage, pure perishable organic matter that does not contain RDF, metals and inorganic particles cannot be obtained. Perishables accounting for nearly half of the weight of garbage cannot find a way out, and landfills are still needed. The landfill process continues to produce leachate , landfill gas and other pollutant emi...
