Abstract

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.
