%X A small-scale experimental study on nitrile wastewater removal using a combination process of moving bed biofilm reactor (MBBR) and biological aerated filter (BAF) was carried out to investigate the degradation law of organic nitrile. After running for 2 months steadily, for two-stage nitrification liquid reflux rate R=200%, pH=7.5 and HRT=3 d, when the average concentrations of COD, CN-, NH3-N, TN and BOD5 of influent were 3 024, 38, 185, 305 and 845 mg/L, respectively, their average concentrations of effluent were 50, 0.5, 10, 45 and 17 mg/L, respectively. And their removal efficiencies were 98.2%, 98.7%, 94.2%,85.2% and 98.0%, respectively. The ratio of BOD/COD rose from 0.29 to 0.34, and the effluent could meet the Standard (Grade-1) of Jiangsu Province Chemical Industry Major Water Pollution Discharge (DB32/939-2006).
