TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The refuse sorting system sorts refuse into three parts such as the ingredient used for producing RDF, the biodegradable ingredient used for fermenting and incombustible ingredient neither used for producing RDF nor used for fermenting. The ingredient not suitable for producing RDF and the ingredient not suitable for fermenting are filtered for reclaiming or burying treatment in the refuse sorting process. The method involves removing coarse and irregular matters such as bricks, stones etc. for burying or manufacturing construction material, sending bamboo, wood etc. to RDF producing system, sorting original refuse to heavy ingredient, mid-heavy ingredient and light ingredient through breaking and sorting, removing black metal from heavy ingredient through magnetic separation to be filtered from the system, remaining ingredient in the heavy ingredient are sent to a trammel screen for processing, sending light ingredient to RDF producing system, sorting rest ingredient in heavy ingredient and mid-heavy ingredient with trammel screen, sending the ingredient suitable for producing RDF into the RDF producing system, sending glass, wasted food, and other waste into the refuse fermentation system through breaking and shaking-bed sorting treatment, sending selected organic matters to the refuse fermentation system to perform fermentation, excluding the matters used for fermentation. The method for fermenting refused ingredients based on sorting result, involves sending organic matters suitable for fermentation from sorting system to an anaerobic fermentation reactor to perform fermentation, purifying methane produced by anaerobic fermentation reactor through methane purifying apparatus, performing stabilized dewatering to the filtered waste sorted out from the anaerobic fermentation reactor, sending purified methane as an energy resource to RDF producing system for producing RDF, generating electric power using surplus methane, sorting out fen waste after being stabilized and dewatered to produce base manure, and producing surface manure and top application using fen liquid. The method for producing RDF, involves breaking RDF sent into the refuse sorting system, adding produced material of RDF with qualified size into additional agent to be sent into a main reactor for processing, compressing fix shape with a compressing forming machine and drying with a drying machine to produce RDF products. The energy balance distributing method for producing refuse derived fuel, involves providing organic waste originally used in anaerobic fermentation system as material for producing RDF to the RDF producing system which is finished before the organic waste enters the fermentation system. The quantity of organic waste being sent to the RDF producing system is accurately commanded through energy balance calculation.
