| 摘 要： | 含水量是影响垃圾土中有机物降解的因素之一,本文根据重庆市垃圾土的成分特点,自配生活垃圾试样进行试验,研究在不同的含水量情况下,由于有机物的降解而引起的垃圾土的质量变化情况。试验结果表明:试样的质量变化在试验初期较大,随着时间推移,质量变化逐渐减小,至试验后期,质量基本无变化。通过数据拟合可知,质量变化及有机物的降解率呈现指数型衰减规律,降解速率有先增大后减小的趋势。水对有机质降解有促进作用,当含水量为50%时,有机物最易发生降解。

| Abstract: | The water contents of municipal solid waste(MSW)are one of the factors affecting organic matters degradation.According to the component characteristics of Chongqing MSW,the authors confected MSW samples and tested their quality variations due to organic matter degradation under different water content conditions.The results showed that in the initial stage of experiment,the quality variation of MSW was obvious,along with the time passing by,the variation tended to minish gradually and there was minimal vari... |
