【摘要】 通过对 2种不同含水率的污水厂污泥 (含水率 80 %的污泥a和含水率 45 %的污泥b)的防渗性能、抗剪切性能的研究 ,排除了污泥b作覆盖材料的可能性 ,提出了一个采用污泥a作覆盖材料的方案。同时 ,污泥中 5种主要重金属的含量 ,并未超过《农用污泥中污染物控制标准》(GB 42 82 -84)的规定 ,可以考虑在污泥覆盖土体上栽种植被 ,防止泥土流失更多还原

【Abstract】 By studying impermeability and anti\|shear performance of the sludge from wastewater treatment plant with different water content (sludge a with 80 percent and sludge b with 45 percent), this article excludes the possibility of using sludge b as landfill final cover material but presents a proposition of utilizing sludge a.We determined the metal contents of sludge and found none is beyond the national standard“Control Standards for Pollutants in Sludge from Agricultural Use”(GB 4284-84),meaning that it is feasible to plant vegetation on it and thus to prevent mud erosion.更多还原
