为了研究北京地区典型简易垃圾填埋场垃圾体的内部特征,在现场测定了垃圾体内部温度随深度的变化规律,并在室内测定了垃圾体的成分、含水率和有机质含量随深度的变化.结果表明:对于填埋深度较浅的垃圾场,垃圾体内部温度随填埋深度增加而降低,填埋深度较深的垃圾场,垃圾体内部温度则随填埋深度的增加而提高,但达到某一峰值后又呈逐渐下降的趋势;有机质随填埋深度增加而减小;含水量随着有机质质量分数的增加表现出逐渐增大的趋势.
The internal properties of waste body on typical simple waste landfill were researched in Beijing area. The variable regularity of internal temperature with filled depth of waste body was measured in site. The variable regularities of waste component, rate of water content and organic content with filled depth of waste body were found indoors. Results show that the inner temperature in the waste will decrease with increasing of dumping depth for superficial landfill, yet the inner temperature in the waste will increase with increasing of dumping depth for deep landfill until reaching peak value, then the adverse results can be obtained. The quantity of organic matter will decrease with increasing of dumping depth, and the water content values measured have indicated to increase with increasing mass of organic matter.
