ANALYSIS OF UTILIZATION AND DISPOSAL METHODS OF TYPICAL RURAL SOLID WASTE IN CHINA BASED ON ITS CHARACTERISTICS

摘要

摘要: 基于全国12个省份、72个典型村镇生活垃圾的采样调查,系统分析了垃圾组分组成、含水率、湿基低位热值、肥效指标(有机质、TN、TP、TK)及重金属含量对焚烧、堆肥及填埋技术可行性的影响。结果表明:村镇生活垃圾全组分、可燃组分、可燃组分(厨余类除外)的湿基低位热值分别为4263,5652,13772 kJ/kg,村镇生活垃圾进行焚烧处理,分选环节可显著提高湿基低位热值。村镇生活垃圾有机质、含水率、N、P、K含量等方面,均基本满足堆肥化处理有关要求,可进行堆肥处理,但部分地区Cd含量超标,应强化源头分类,控制堆肥产品的品质,降低环境风险。村镇生活垃圾填埋处理前对可回收垃圾和有害垃圾进行分类回收,可减少约1/3的填埋垃圾量,并最终减少垃圾填埋渗滤液的污染风险。

Abstract: Based on the sampling survey of domestic waste in 72 typical villages and towns in 12 provinces, the impacts of waste composition, water content, wet base low calorific value, fertilizer efficiency indicators (organic matter, TN, TP, TK) and heavy metal content on the feasibility of incineration, composting and landfill technology was systematically analyzed. The results showed that the wet base low calorific value of the whole components, combustible components, and combustible components except kitchen waste of village and town domestic waste were 4263, 5652, 13772 kJ/kg, respectively. The wet base low calorific value of village and town domestic waste could be significantly increased in the process of sorting after incineration. The organic matter, water content, nitrogen, phosphorus, potassium content and some other indexes of the household garbage in villages and towns basically meet the requirements of composting treatment. Composting treatment can be carried out, but Cd content in some areas exceeds the standard. Therefore, source classification should be strengthened to control the quality of composting products and reduce environmental risks. Classified recycling of recyclable waste and hazardous waste before the landfill treatment of rural domestic waste can reduce the amount of landfill waste by about 1/3, and ultimately reduce the pollution risk of landfill leachate.
