| 对广东省韶关地区的始兴、仁化和江门地区的新会、鹤山4县（市）农村生活垃圾的组分、含水率、肥效指标以及主要重金属含量进行了分析测定。结果表明：调查区域内农村生活垃圾中可堆肥类含量高达62.62%，主要包括厨余尘土和草叶，其次是非堆肥类中的易燃类垃圾（木竹、纸、布、塑料等），平均含量为总量的29.97%，金属、玻璃以及砖瓦石等难以降解类的垃圾含量占6.61%，电池以及农药化肥包装袋等污染类垃圾的含量占0.81%；韶关地区农村垃圾中的可堆肥类组分明显高于江门地区的相应组分，而江门地区农村垃圾中塑料的含量明显高于韶关；可堆肥类垃圾含水率较高，而其他组分含水率相对较低；各区域农村垃圾中N、P、K和有机质的含量都符合垃圾农用的营养元素标准；各区域农村生活垃圾中各项重金属含量均低于垃圾农用控制标准，并可达到《土壤环境质量标准》中的二级标准，说明广东省的农村生活垃圾农用是可行的和安全的。结合各地区自身的实际情况，因地制宜地将农村垃圾回馈农村的生产和生活，如堆肥处理或发酵产生沼气等，不但可减少垃圾污染，而且还可实现农村垃圾的无害化、减量化和资源化。 |

| In order to understand the nature of domestic garbage generated in rural Guangdong today, samples were collected from rural families of four counties in Guangdong Province including Shixing, Renhua which is located in Shaoguan City in the north, Xinhui and Heshan which is located in Jiangmen City in the mid-south. The composition, moisture content, total nitrogen（TN）, total phosphorus（TP）, total potassium（TK） and heavy mental in the waste samples were measured. The results showed that the organic components which could be returned to field through composting such as food waste, kitchen waste and plant residues in the garbage, reached 62.62% of the total weight. The flammable part of the garbage including plastics, paper and cloth was accounted for 29.97% of the total weight. The non-degradable part such as metal, glass and bricks was 6.61%. Hazardous materials such as battery and packing material for pesticide and fertilizer, was only 0.81% of the total weight. The organic part of the garbage from two counties in Shaoguan was significantly higher than that from the two counties in Jiangmen City. The content of waste plastics in garbage from Jiangmen was significantly higher than that from Shaoguan. The moisture content in the organic part was quite high, while moisture contents in other parts were relatively low. The TN, TP, TK, organic matter and the main heavy metal in the organic parts of the waste met the control standards set for the wastes used in agriculture. The heavy metal content in organic part reached the second level standard for soil environment quality. It indicated that agricultural utilization of the organic part of waste in rural Guangdong province is not only feasible, but also safe. To make good use of the rural garbage in different ways such as composting, or biogas generation according to the specific situation of the region not only can reduced pollution caused by garbage, but also can realize the reuse, reduction and recycle of the waste. |
