摘要
作者对上海市闵行自来水厂污泥渗透系数、重金属含量、浸出液性质进行了分析研究 ,研究结果表明 ,在10 0kPa压力 (一般填埋场压实设备的压实压力 )下 ,污泥的渗透系数为 1.3× 10 -7cm/s ,符合国家规定 ,污泥可以作为填埋场终场覆盖材料。同时 ,边坡稳定的分析研究结果还表明 ,该厂污泥铺设的斜坡倾角不宜超过 16 .
In this research, we study the permeating coefficient, heavy metal concentration and leachate features of the sludge from the Minhang Water Treatment Plant in Shanghai. Results show that under press of 100kPa, which could be got by usual press equipment for landfill, the permeating coefficient of the sludge will be 1.3×10 -7 cm/s, complied with the demands of nation standard, and this means the sludge can be used as landfill cover material. At the same time, analysis of the slope stability shows that the slope obliquity should better be less than 16.5 degree.
