一种用水泥基复合材料深度净化生活垃圾渗滤液难降解尾水的方法
摘要：
一种用水泥基复合材料深度净化生活垃圾渗滤液难降解尾水的方法。先构建可渗透反应层：将硅酸盐水泥和分析纯CaCO3粉末按质量比2～3∶1混合均匀后填入底部有小孔的PVC柱中。然后从反应层上方间歇喷洒待处理的渗滤液尾水，控制渗出水负荷(渗出水体积·反应材料质量-1·天-1)在0.6～0.8mL·g-1·d-1左右。尾水渗过反应层后从柱底部的小孔聚滴渗出。该可渗透反应层在20天内保持出水达到GB16889-1997二级排放标准。反应材料可多次再生，再生方法为在900℃下灼烧1h。再生后材料保持处理效果的天数随再生次数增加而逐渐减小。本工艺基建和运行费用低、操作维护方便、耐负荷冲击、使用寿命长，应用前景广泛。
