为了验证A2O-MBBR工艺在某城市污水厂提标改造应用的可行性,采用规模为1 m3/h的A2O-MBBR中试装置进行了模拟试验研究。试验结果表明,中试装置出水CODCr、 NH3-N、 TN和TP平均质量浓度可分别达到37、0.61、10、0.55 mg/L,基本满足GB 18918-2002《城镇污水处理厂污染物排放标准》一级A排放标准的要求,采用A2O-MBBR工艺用于城市污水厂提标改造是可行的。
為瞭驗證A2O-MBBR工藝在某城市汙水廠提標改造應用的可行性,採用規模為1 m3/h的A2O-MBBR中試裝置進行瞭模擬試驗研究。試驗結果錶明,中試裝置齣水CODCr、 NH3-N、 TN和TP平均質量濃度可分彆達到37、0.61、10、0.55 mg/L,基本滿足GB 18918-2002《城鎮汙水處理廠汙染物排放標準》一級A排放標準的要求,採用A2O-MBBR工藝用于城市汙水廠提標改造是可行的。

In order to verify the feasibility of the application of A2/O-MBBR process for upgrading and re-construction of an urban wastewater treatment plant, a 1 m3/h pilot scale test on the stimulant wastewater treat-ment by A2/O-MBBR process was investigated. The results of the test showed that, the average mass concentra-tions of CODCr, NH3-N, TN and TP in the effluent from the device reached 37, 0.61, 10, and 0.55 mg/L respec-tively, which could basically meet the specification of grade A class 1 in GB 18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. It could draw a conclusion that, using A2O-MBBR process to upgrade and reconstruct urban wastewater treatment plant was feasible.
