| 摘 要： | 基于A/O工艺与泳动床工艺技术的联合,开发出A/O泳动床生物膜反应器.A/O泳动床系统表现出高效去除COD_(Cr)、NH_3-N和TN以及较好的抗负荷冲击能力.在HRT=12.5 h,回流比为300%,进水COD_(Cr)、NH_3-N平均浓度分别为343.4 mg/L、94.1 mg/L时,COD_(Cr)和NH3-N平均去除率分别为84.6%, 86.8%;COD_(Cr)的容积负荷与去除负荷现良好的线性关系,R~2=0.970 4;系统在较低的C/N下,TN平均去除率为70.8%.

| Abstract: | 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. |
