Wherein, the sludge has water content as 75~85% and bearing capacity less than 10KPa, has mephitis and obvious rheometric feature and small shear strength; the mineralized garbage has almost no harm and stable after buried for 8~10 years.

污泥为含水率75～85％、承压能力小于10KPa、有恶臭气味、流变性明显、抗剪强度小、遇水浸泡后呈膨润持水性、表面感官差的污水厂污泥；矿化垃圾为填埋了8～10年后已基本无害化和稳定化的矿化垃圾。

Cu、Ni、Pb and Cd showed more affinity to the oxidizable metal fraction. Bio-availability of all the measured metals, except Cd,decreased with the increase in composting time. Therefore, we conclude that composting could stabilize the heavy metals present in the sludge and decrease the risk of soil pollution.

污泥堆肥中Cu、Ni、Cd、Cr主要以残渣态形式存在，Cu、Ni、Pb、Cd四种重金属元素的可氧化态含量也相对较高，除Cd外，经过堆肥化处理后所有重金属的有效态含量均呈下降趋势，因此，堆肥可以促进污泥中的重金属稳定化，降低土壤的污染风险。
