摘　　要：通过模拟实验研究生活垃圾生物预处理过程中混合垃圾的有机质和水分含量变化及其对垃圾热值的相关性。结果表明:预处理会降低垃圾有机质和水分;热值与有机质呈正相关(r=0.964),与水分均呈负相关(r=-0.865)。为了提高垃圾热值,建议预处理主要以水分去除为主,减缓有机物降解,采用短期的通风干燥处理为宜。The correlation among organic matter,moisture content and calorific value of mixed waste was studied in the process of domestic waste biological pretreatment by the simulation experiment. The results showed that the biological pretreatment could reduce organic matter and moisture content. Calorific value showed the a positive correlation with organic matter content（r=0. 964）,but showed a negative correlation with moisture content（r=-0. 865）. For increasing waste calorific value,the pretreatment of dehydration was proposed to slow down organic degradation,and short-ventilated was suitable.
