成都市典型地区农村生活垃圾调查及处理模式探讨

Investigation of rural solid waste and discussioin of disposal model in typical area of Chengdu

对成都市典型地区农村生活垃圾人均日产生量、特性进行调查采样、试验分析,结果表明,地处平原的万春镇与地处丘陵山区的万兴乡农村生活垃圾人均日产量分别为0.340、0.194 kg/(人.d),低于城市生活垃圾人均日产量;生活垃圾组分以厨余类为主,分别占39.34%和82.49%,主要与经济发展水平及地理位置有关。不同地区生活垃圾的含水率、生物降解度、热值也有差异,这主要是垃圾成分的差异所致。根据垃圾特性,可通过回收、堆肥、焚烧、填埋等组合方式进行处理。基于对村民的问卷调查,推荐采用先就地消纳再分类收集、分类处理的农村生活垃圾处理模式。
