构建以粒径3~6 mm活性炭颗粒为填料的厌氧污水处理系统，厌氧消化菌和反硝化菌在活性炭颗粒表面附着成膜，考察不同C/N对厌氧同步消化反硝化的影响。以葡萄糖为有机碳源，进水中葡萄糖质量浓度分别为300 mg · L-1和400 mg · L-1时，较高 C/N 对 NO3-- N 去除有利，最高去除率为95.21%；较低C/N对COD和NH4+-N的去除有利，最高去除率分别达到96.00%和42.43%以上。研究表明，以活性炭颗粒为填料的厌氧高效处理废水技术是可行的，不同C/N对厌氧同步消化反硝化处理含氮和有机物废水具有较明显的影响。

An anaerobic wastewater treatment system was constructed based on granular activated carbon acted as carrier for anaerobic digestion bacteria and denitrifying bacteria adhesion, and the effect of C/N on anaerobic simultaneous digestion and denitrification process was studied. The concentration of glucose in the influent was respectively 300 mg/L and 400 mg/L, which acted as the only source of organic carbon. High C/N was better for NO3- -N removal and the maximum removal rate of NO3- -N was 94. 32% at a C/N ratio of 12. 87. However, low C/N was better for COD and NH4+ -N removal and the maximum removal rate of which was 96. 00%and 42. 43% at a C/N ratio of 9. 65, respectively. These facts indicated that the technique with granular activated carbon acted as carrier was better for anaerobic wastewater treatment, and dif-ferent C/N ratio obviously affected the removal of COD and nitrogenous pollutant.
