刘晓琎, 蒋秋静, 曹霞. Study on Denitrification and Methanogenesis of Landfill Leachate Treatment in Anaerobic Composite Bed[J]. 2011, 32(6): 712-716.
在厌氧复合床反应器中进行了垃圾渗滤液的反硝化/产甲烷的试验.试验结果表明
处理有机物浓度较高的垃圾渗滤液时
反硝化/产甲烷能够在厌氧复合床反应器中实现同步进行.下部的污泥床承担了主要的反硝化任务
当进水COD/NO3-N9时
下部污泥床对NO3-N的去除率可达到99%以上.随着进水COD浓度的提高
达到4 000 mg/L以上时
下部污泥床和上部生物膜对COD的去除能力均趋于稳定.下部污泥床稳定在6.0
7
.0 g COD/(L.d);上部生物膜稳定在5.0
6
.0 g COD/(L.d).
The landfill leachate treatment test of denitrification/methanogenesis was done on the anaerobic composite bed reactor.Test results show that
denitrification/methanogenesis can simultaneously occur in anaerobic composite bed reactor if there is high concentration of organic matter.The lower sludge bed contributed to the denitrifying progress mainly.When COD/NO3-N is higher than 9
removal rate of NO3-N can reach 99 percent in the lower sludge bed.When the inflow COD reaches 4 000 mg/L
COD removal capacities of upper biofilm and lower sludge bed remain stable
which of the bottom sludge bed is at 6.0
7
.0 g COD/(L·d)
and upper biofilm 5.0
6
.0 g COD/(L·d).
