摘要: 采用固定化微生物深度处理垃圾渗滤液，研究水力停留时间（HRT）、溶解氧（DO）和进水pH对系统脱氮效果的影响。通过对厌氧出水和好氧出水的脱氮效果比较，探讨固定化微生物构筑物的合理位置。结果表明：固定化微生物处理厌氧出水时，最佳HRT为72 h，最佳DO为5 mg·L-1，最佳进水pH为7.5~8.5；处理好氧出水时，最佳HRT为84 h，最佳DO为5 mg·L-1，最佳进水pH为7.5~8.5；处理厌氧出水和好氧出水时氨氮平均去除率分别达到63.8%和92.6%，将固定化微生物构筑物单元设置在好氧处理之后更合理，可以充分发挥固定化微生物处理渗滤液脱氮方面的独特优势，切实解决渗滤液高效脱氮的问题。

Abstract: Immobilized microorganisms were used for the advanced treatment of landfill leachate to investigate the effects of hydraulic retention time (HRT),dissolved oxygen (DO)and influent pH on nitrogen removal,as well as the reasonable position of immobilized microorganisms,by comparing the extent of nitrogen removal from the anaerobic and aerobic effluents. The results indicate that when immobilized microorganisms are used to treat anaerobic effluents,the optimal HRT is 72 h,DO is 5 mg·L-1 and the influent pH is from 7.5 to 8.5,whereas for aerobic effluents,the optimal HRT is 84 h,DO is 5 mg·L-1 and the influent pH is from 7.5 to 8.5. When treating anaerobic and aerobic effluents,the average ammonia removal rate achieved was 63.8% and 92.6%,respectively. It seems more reasonable to include the treatment system using immobilized microorganisms after the aerobic treatment,as it is more conducive to nitrogen removal by immobilized microorganisms,effectively solving the problem of efficient denitrification of landfill leachate.
