杭州市农村生活垃圾分类减量资源化模式经济性分析

摘要

以杭州市为例, 探索了中国两种主要的农村生活垃圾处理模式, 对比分析了传统全集中模式 (CTP) 和分类减量资源化模式 (SCTP) 的经济性.结果表明:CTP垃圾平均处理成本为369.17元/t, SCTP垃圾平均处理成本488.14元/t.不考虑资源化产品 (有机肥料) 经济价值的前提下, SCTP垃圾处理成本高于CTP.考虑到其环境、社会效益和资源化产品的经济价值, 适度集中、适当规模化建设与运行, SCTP应具有经济可行性和现实可操作性.综合源头分类质量、垃圾处理经济性、资源化效益等因素, 农村生活垃圾SCTP最佳组合应为门前投放+上门收集+机器成肥.%This paper studied two main rural domestic waste treatment patterns-conventional treatment pattern (CTP) and source classified waste treatment pattern (SCTP) in Hangzhou.Results showed that the average cost of rural domestic waste treatment in CTP and in SCTP was 369.17 yuan per ton and 488.14 yuan per ton, respectively.The rural domestic waste treatment cost of SCTP was higher than that of CTP.However, considering the economic value of the fertilizer characterization, environmental and social benefits, SCTP was economically acceptable.Besides, moderate centralization and scale-up could make SCTP more economical and practical.Considering the quality of source separation, the cost of treatment, the benefit of resource, etc., the optimal pattern was a combination of household separation, door-to-door collection, and mechanical composting.
