项目摘要

Three types (anaerobic,semi-aerobic and circulatory semi-aerobic landfill type) of lysimeter were designed and constructed to indicate the accelerated stabilization of incombustible solid waste. The experiment conducted on three types of landfills clarified the facts as fellows;1. The circulatory semi-aerobic landfill type is decreased approximately 30% of leachate quantity.2. The circulatory semi-aerobic landfill type lead to reduce rappidly BOD and Total Nitrogen(TN) of leachate at initial period.3. The decreasing ratio of organic matter is semi-aerobic circulatory semi-aerobic anaerobic landfill type.4. In circulatory semi-aerobic and semi-aerobic landfill type the bacterial counts in NB media decrease with the purification of leachate. At the same time, the bacteria group that have the decomposability of organic matter such as cellulose is predominated in flora, and their counts and ability of circulatory semi-aerobic and semi-aerobic landfill type is higher than anaerobic.5. The heavy metals in the waste had been released through leaching only 0.3% of initial content and remain over 99% in the waste.6. The ratio spore forming bacteria counts in the incombustible solid waste landfill is higher than the combustible as refuse.We would be gralified of our findings can contribute to the waste disposal problems.

设计并建造了厌氧、准好氧和循环准好氧填埋式渗滤仪，用于指示不可燃固体废物的加速稳定化。在三种类型的垃圾填埋场上进行的试验表明：1.循环式准好氧填埋场的渗滤液量减少了约30%。循环式准好氧填埋型导致渗滤液初期BOD和总氮(TN)的快速下降。有机质下降率为半好氧循环半好氧厌氧填埋型。在循环式、准好氧型和准好氧填埋型垃圾渗滤液中，随着渗滤液的净化，NB中的细菌数量减少。同时，植物区系中具有纤维素等有机物分解能力的细菌群占优势，循环半好氧和准好氧填埋型的细菌数量和能力均高于厌氧填埋型。垃圾中重金属的淋溶释放量仅为初始含量的0.3%，且仍保持在99%以上。不可燃固体垃圾填埋场中的芽胞形成菌数比例高于可燃垃圾填埋场。我们的研究结果将有助于垃圾处理问题的解决。
