| 摘 要： | 在大型模拟填埋试验装置(21 m×3.8 m×6.0 m)上，研究了准好氧填埋渗滤液水质的主要指标CODCr、BOD5、NH3+-N和pH的变化特性.结果表明，准好氧填埋结构下渗滤液CODCr、BOD5浓度下降很快，没有出现在传统填埋场累积的现象，并且封场后39周分别降为173和30 mg·L-1；NH3+-N浓度下降更为显著，第39周降为15 mg·L-1，下降率达到99.6%，为渗滤液后续处理解决了NH3+-N浓度过高的难题；pH值在前2周略低于7，第3周后一直呈弱碱性.根据实验数据,拟合了准好氧填埋结构渗滤液污染物的衰减方程.

| Abstract: | A large-scale semi-aerobic landfill set (21 m x 3.8 m x 6.0 m) was constructed to study the variation characteristics of pollutants in the landfill leachate. The results showed that after 39 weeks, the concentrations of CODCr, BOD5 and NH3+-N in the leachate declined rapidly, which reached 173, 30 and 15 mg x L(-1) respectively, and the reducing rate of NH3+-N was 99.6%. The pH value was below 7 during the first 2 weeks, but became weak alkaline after three weeks. Based on the experimental data, the attenuation equations of pollutants in the leachate were built. |
