| 摘 要： | 依据准好氧填埋的原理构建了准好氧填埋模拟试验装置。在填埋不同区域内布设渗滤液采样器定期进行渗滤液采样，并对渗滤液进行水质分析．分析指标包括COD、总氮、氨氮、硝态氮和亚硝态氯等。结果表明，由于受氧气浓度、氨氮浓度等的影响，不同区域内反硝化类型是不同的。好氧和准好氧区域内以好氧反硝化为主，厌氧区域内以传统厌氧反硝化为主，同时研究表明高浓度氨氮对好氧反硝化的抑制作用小于对传统厌氧反硝化的抑制。

| Abstract: | Semi-aerobic landfilling experiment installation was constructed according to semi-aerobic landfilling theories.Sampling devices were set in different regions to detect the mass concertrations of TN,ammonia nitrogen,nitrate nitrogen and nitrite nitrogen in leachate.The results showed that the types of denitrification in different regions were different because of the influence of O2 and ammonia nitrogen.The aerobic denitrification was the main type in aerobic and semi-aerobic regions,and the anaerobic denit... |
