摘    要:东江系广东及香港的饮用水源地,其源区包括江西省赣州市的寻乌、安远和定南3县。本研究在东江源区选取了3个典型村庄,调查农村生活垃圾的产生量及物理特性。调查发现:东江源区农村生活垃圾主要以厨余类垃圾为主,可达60%以上;其次是灰土类垃圾,可达12%以上,其他组分一般在10%以下。县级村人均垃圾产生量一般在0.2~0.47 kg·d^-1,平均0.36 kg·d^-1;镇级村人均垃圾产生量在0.18~0.35 kg·d^-1,平均0.29 kg·d^-1;普通村人均垃圾产生量在0.07~0.33 kg·d^-1,平均0.17 kg·d^-1。混合生活垃圾含水率与厨余类垃圾所占的比例呈显著线性相关(R^2=0.626,P=0.019)。混合垃圾平均热值在2329 kJ·kg-1,不适合直接进行焚烧处理。

Abstract:Dongjiang river is the source of drinking water of Guangdong Province and Hongkong, and the source area includes three counties in Ganzhou city of Jiangxi Province:Xunwu, Anyuan and Dingnan. Three typical villages were chosen in Dongjiang river source area to inves-tigate the producing quantity and physical characteristics of rural solid waste. Results of investigation showed that the dominant ingredient in rural solid waste in Dongjiang river source area was kitchen waste, taking over 60%, followed by dust, reaching 12%, while other components took less than 10%. The per-capita producing quantity of solid waste of county-level village was 0.2~0.47 kg·d^-1 and averaged by 0.36 kg·d^-1, while that of town-level village was 0.18~0.35 kg·d^-1, averaged by 0.29 kg·d^-1 and that of hamlet was 0.07~0.33 kg·d^-1, averaged by 0.17 kg·d^-1. Water content in rural mixed solid waste of investigated area was significantly linear with percentage of kitchen waste in the mixed waste(R^2=0.626, P=0.019). The average calorie was around 2 329 kJ·kg-1, which indicated that the rural solid waste in Dongjiang river source area was not suitable for incineration disposal directly.
Keywords:Dongjiang river  rural solid waste  composition  physical characteristics
