成都城镇生活垃圾特性及处理方案
Characteristics and treating method of municipal solid waste in Chengdu, China
摘要
Abstract
In order to provide feasible suggestions for the disposal of the urban,suburban,and rural domestic waste of Chengdu,this study investigated the physicochemical characteristics of domestic waste.These characteristics are physical composition,moisture content,calorific value,fertilizer efficiency indexes (including organic content,TN,TP,TK,and C/N ratio),and heavy metal content.The results showed that kitchen waste and plastics were the main components of the Chengdu domestic waste,with dust being one of the main components of the suburban and rural waste.All the mixed domestic waste of Chengdu area met the requirement for combustion;however,the calorific value of urban waste was the highest (5734 to 5955 kJ · kg-1),while that of suburban waste was the lowest (5499 to 5603 kJ · kg-1).Although the Cd,Hg,and Cu contents in some samples were above the quality standard of soil,they were still far below the waste control standard for agriculture.Furthermore,the component for compost accounted for approximately 80％ of the entire volume of waste,and it was suitable for agriculture because of its good fertilizer efficiency indexes.As a result,based on disposing hazardous waste separately,recycling the suitable waste,and considering the construction situation and the position of waste incineration plants in Chengdu,various suggestions are provided.Urban waste and that of suburban incineration plants and the surrounding rural areas is mixed,and collected for combustion.The waste of eight suburban plants and the surrounding rural areas,adjacent to the incineration plants,is sorted as compost components.As regards the rest,the former (about 80％) is suitable for agriculture in the vicinity,and the latter (about 17％) is collected and transported for combustion.The waste of four suburban areas and the surrounding rural areas,far from the incineration plants,is mixed waste collected mainly for agriculture.关键词
