以重庆市涪陵区李渡镇生活垃圾处理厂为例,分析了前分选工艺在垃圾综合处理中的减量化和资源化效果,探讨了前分选工艺对提高生活垃圾综合处理水平的作用.结果表明:通过对原生垃圾进行分选,使堆肥物料、可回收物料和填埋物料实现了有效分流.其中,一次发酵仓的堆肥物料质量相对于原生垃圾减少了16.6%,堆肥物料容积减少了51.4%,堆肥物料的密度增加了67%,且较均匀、含水率低,提高了物料的堆肥特性.通过对前分选工艺各分选出料口物料的分析,前分选工艺对金属的分选效率为92.0%,对塑料的分选效率为63.5%,对玻璃的分选效率为33.0%,分选出的可回收物料质量占分选线分选出物料总量的44.2%,提高了原生垃圾的资源化水平.

Taking Lidu MSW disposal plant as an engineering example, the reduction and recla-mation efficiencies of waste by preceding separating process in comprehensive treatment of domestic waste were analyzed, and the effect of preceding separating process on improving comprehensive treatment of domestic waste was explored.The results indicate that composting materials, recoverable materials and landfill materials can be effectively separated by separately selecting raw refuse.Compared with the raw refuse, the weight of eomposting materials in primary fermentation unit is reduced by 16.6%, the volume is reduced by 51.4%, while the bulk density is increased by 67% after separation, being homogeneous in density and with low moisture content, which improves the composting characteristics of materials.Based on the classification results of materials from each separation discharging pit of preceding separating process, the separation effieiencies of metal, plastics, glass through preceding separating process are 92.0%, 63.5% and 33.0% respectively.The weight of recoverable materials accounts for 44.2% .of materials separated out, which increases the reclamation level of raw refuse.
