摘要
以重庆市主城区为例,通过分析生活垃圾的理化性质(组分、容重、发热量和三成分包括含水率、可燃分、灰分),确定其时空变化特征和随机特性,为重庆市的环境保护提供帮助。重庆市主城区生活垃圾的理化性质具有4个特点(1)生活垃圾理化性质随季节变化明显;(2)生活垃圾的大多数理化性质空间差异较小,发热量差异较大;(3)容重、低位发热量和高位发热量总体上满足正态分布;(4)三成分和垃圾组分总体上满足逻辑加法正态分布。
Taking main city area of Chongqing city as an example, both temporal &spatial changing characteristic and random characteristic of refuse's physic-chemical property were determined by analyzing refuse's physic-chemical property (including composition,volume-weight,calorific value and contents of water,combustible material and ash),which can provide help for protecting environment of Chongqing. There are four characteristics of refuse's physic-chemical property in Chongqing. First, the physic-chemical property varies greatly with season. Secondly, the difference of physic-chemical property except for calorific value among nine districts is little. Thirdly, the distribution of volume-weight and calorific value basically satisfied normal distribution. Finally, composition of refuses basically satisfied additive logical normal distribution,and united distribution of water content, combustible content and ash content is also nearly additive logical normal distribution.
