EVALUATION OF CLASSIFICATION EFFECT OF KITCHEN WASTE AND OTHER WASTE AND ENERGY UTILIZATION EFFICIENCY USING MOISTURE CONTENT: A CASE STUDY OF ZHANGJIAGANG

School of Environment, Tsinghua University, Beijing 100084, China

摘要

摘要: 随着垃圾分类的快速推广，厨余垃圾单独处理将会影响城市垃圾的能源回收效率，因此应考虑城市固有处理设施规模合理规划。通过实地调研和文献研究，测定了张家港市20个居民小区生活垃圾的含水率及热值，并预测了该市其他垃圾含水率及热值随着厨余垃圾分离效率的变化。研究发现，根据张家港市现有的生活垃圾处理设施情况，能源回收效率随着厨余垃圾分出率的提高先增加后降低。在最优分出率（70.8%）条件下，全市生活垃圾的管理可实现原生垃圾零填埋，且可实现能源最大化利用。对于垃圾分类新形势下城市管理部门设计垃圾分类投放、收集和处理方案具有一定指导意义。

Abstract: With the rapid promotion of waste classification in China, kitchen waste utilization will have a great influence on the energy recovery efficiency of municipal solid waste. Therefore, urban waste treatment infrastructure should be reconsidered. The objective of this work was to measure the moisture contents and heating values of municipal solid waste from 20 communities in Zhangjiagang through field investigation, and predict the changes of moisture contents and heating values of dry waste under different separation rates of kitchen waste. The results showed that based on the existing domestic waste treatment facilities in Zhangjiagang, the separation rate of kitchen waste was not the higher the better. Under the optimized separation rate of 70.8%, zero primary landfill could be realized, and energy recovery efficiency from municipal solid waste could reach the maximum. For the new era of waste classification, the results obtained in this paper was of guiding significance in design of municipal solid waste management scheme for urban administration.
