生活垃圾填埋场污泥塘处置方式探讨

Discussion on Domestic Garbage Treatment with Landfill Pond Method

目前国内许多生活垃圾填埋场接纳未达到入场技术要求的市政污泥,既要考虑尽量增加库容以满足填埋场使用年限的要求,又要对库区内现有的污泥塘进行处置以确保安全运行。文章以某填埋场污泥塘处置方案为例,探讨了针对污泥塘的加固措施,计算了加固前后垃圾堆体竖向位移、水平位移、不均匀沉降以及堆体边坡稳定系数等主要参数,设置加筋垫层一方面能提高地基承载力,另一方面减少了竖向和水平向位移和不均匀沉降,是处置污泥塘的有效措施。

Currently, many domestic waste landfill sites are forced receive municipal sludge that failed to meet technical requirements. They have to increase capacity to meet the requirements for meeting the landfill site life, but also to secure the safe operation of existing sludge stored in the sludge pond. Taking a sludge landfill pond as an example, this study discusses the reinforcement measures for sludge pond, calculated the landfill body vertical displacement and horizontal displacement before and after reinforcement, uneven settlement and pile body slope stability coefficient, main parameters, such as setting reinforced cushion on the one hand. The method can improve the bearing capacity of foundation, on the other hand to reduce the vertical and horizontal displacement and uneven settlement. It is an effective measures for disposal of sludge pond.
