重庆市典型村庄生活垃圾产生特征及处理模式

采用现场调查方法对重庆江津区慈云镇凉河村、蔡家镇鸳鸯村、龙华镇燕坝村和巴南区界石镇武新村4个典型村庄的生活垃圾的产生特征进行了调查,在此基础上探讨了重庆农村生活垃圾的处理模式.结果表明,4个村庄的生活垃圾人均日产生量分别为0.217±0.124,0.226±0.168,0.286±0.203和0.282±0.123kg,且不同月份间差异较大.垃圾组分中,厨余垃圾所占的比例在45%~55%之间,包装纸和塑料包装袋类所占比例分别在9.5%~17.0%和8.22%~20.0%之间,其他成分比例相对较低.根据村镇交通条件、距县级及以上生活垃圾处理设施的距离、居民点的分散程度,提出重庆市农村生活垃圾宜采取户分类后再城乡一体化、连片村镇集中式和分散式处理等3种收集处理模式的建议.

Characteristics of Rural Household Solid Waste in Typical Villages of Chongqing and Its Treatment Models

Site investigations were made of the characteristics of the rural household solid waste in four typical villages of Chongqing, including Lianghe village and Yuanyang village in Ciyun town, Yanba village in Longhua town of Jiangjin District, and Wuxin village in Jieshi town, Banan District, and its collection and treatment models in Chongqing were discussed. The results showed that the amounts of domestic solid waste per capita of the four villages were 0.217±0.124, 0.226±0.168, 0.286±0.203 and 0.282±0.123 kg, respectively, and they varied greatly with months. Kitchen waste, wrapping paper and plastic bags accounted for 45%-55%, 9.5%-17.0% and 8.22%-20.0%, respectively, of the total amount, and the percentages of other components were relatively low. According to the traffic conditions of the villages/towns, the distance to the centralized garbage disposal facilities and the dispersion degree of settlements, three collection and treatment models for the rural household solid waste of Chongqing are recommended in this paper.
