| 摘 要： | 选择了泥土、矿化垃圾、粉煤灰和建筑垃圾4种改性剂改性城市污水处理厂污泥(以下简称污泥)。结果表明:(1)随着4种改性剂与污泥的混合比增大,混合物含水率降低。(2)当混合比为0.7(质量比)时,各种混合物的抗压强度都达到50kPa的填埋要求;当混合比为0.3～1.0时,混合物的抗压强度随着混合比的增大呈指数形式增大;比较4种改性剂对抗压强度的增大能力,粉煤灰最强,建筑垃圾次之,泥土和矿化垃圾较弱。(3)在50kPa预压力下,混合物要达到不小于25kPa的抗剪强度,泥土与污泥最小混合比为1.0,矿化垃圾与污泥最小混合比为1.0,粉煤灰与污泥最小混合比为0.7,建筑垃圾与污泥最小混合比为0.7。(4)除加泥土的混合物外,混合物压缩系数随着混合比的增大呈总体下降趋势。(5)粉煤灰除臭效果最好,矿化垃圾次之,建筑垃圾较差,泥土最差。

| Abstract: | The batch experiments were conducted to modify the geotechnical properties of sewage sludge by 4 soil modifier (coal ash,construction wastes,soil and aged refuse). The modifier and sewage sludge was mixed with mass ratio of 0.1,0.3,0.5,0.7,1.0 and 1.5,the effect of mixing ratio on geotechnical properties of sewage sludge was investigated. The results showed that the moisture of sludge decreased with increasing of mixing ratios;when the modifier and sludge mixed with ratio of 0.7,the obtained sludge had the ... |
