摘要
分析了常规卫生填埋场 (CL)的缺点 ,对“生物反应器型”垃圾填埋场 (BL)的结构特点进行了简要的描述 ,并以美国加里福尼亚州一“生物反应器型”垃圾填埋技术研究项目为例 ,对该技术的生物降解特性进行了介绍。目前已获得的试验结果显示 ,由于增加了渗滤液的循环、垃圾水分的控制等措施 ,使得 BL 的生物消化能力明显提高。与常规无控制的卫生填埋方法 CL 相比 ,BL 的垃圾填埋气产量可提高 75 % ,体积减少量增加约 4倍 ,且渗滤液稳定快 ,一般不需渗滤液处理设施。最后 ,对我国垃圾处理技术的现状进行了简要的分析 ,说明 BL
The disadvantages of conventional Sanitary Landfill(CL) were analyzed, and the structural characteristics of Bioreactor Landfill(BL) were described, and the biodegrading characteristics of BL technology was introduced by taking a BL research project conducted in California as an example. The preliminary experimental results showed that the biodegradation capability of BL was strongly enhanced due to the leachate recirculation and moisture content adjustment. As compared with CL, BL could increase 75% landfill gas amount and approximately 4 fold landfill volume reduction, and faster leachate stabilization. Finally, the current status of refuse treatment technologies in China was analyzed, and the potential application of BL technology in China was investigated as well.
