Anoxic/oxic(A/O) process combined with swimming bed as a novel technology for wasterwater treatment was developed, which was on the basis of A/O process and swimming bed technology.The results demonstrated that A/O swimming bed system has the performance of high-efficiency removal of COD_(Cr)、NH_3-N and TN, as well as resistant to flash loading.When hydraulic retention times (HRT) was at 12.5 h with average concentration of influent wasterwater's COD_(Cr) and NH_3-N of 343.4 mg/L、94.1 mg/L,the average COD_(Cr) and NH_3-N removal rate of 84.6% and 86.8% were achieved separately.Linearity relationship was appeared between volumetric loading and removal loading, R~2=0.970 4;70.8% of average remaoval rate were achieved in lower ratio of C/N.
