Study on the solid waste disposal of "The Circuratory Semi-aerobic Landfill Type"

设计并建造了厌氧、半好氧和循环半好氧填埋场三种类型的渗滤仪，以表明不可燃固体废物的加速稳定化。在三种类型的垃圾填埋场进行的实验，澄清了事实。循环半好氧填埋方式减少了约30%的渗滤液量。循环半好氧填埋方式在初期能迅速降低渗滤液的BOD和总氮（TN）。有机质递减比例为半好氧循环半好氧厌氧填埋类型。在循环半好氧和半好氧填埋场中，随着渗滤液的净化，NB培养基中的细菌数量减少。同时，具有纤维素等有机物分解能力的菌群在菌群中占主导地位，其循环半好氧和半好氧垃圾填埋型的数量和能力高于厌氧。5 .废水中的重金属通过浸出仅释放出初始含量的0.3%，在废水中仍保持在99%以上。在不可燃固体垃圾填埋场中，孢子形成细菌数量的比例高于可燃垃圾。我们很高兴我们的研究结果能够有助于解决废物处理问题。

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.
