摘要

参照某城镇污水处理厂幅流式二沉池设计了固定化短带鞘藻-活性污泥共生生物膜反应器,在不同水力停留时间(HRT)、氧化还原电位(ORP)和水质条件运行反应器并评价其对总氮(TN)、氨氮(NH_4~+-N)、正磷酸盐(PO_4~(3-)-P)和COD的去除效果。结果表明,当模拟进水中TN、NH_4~+-N、PO_4~(3-)-P和COD_(Cr)浓度分别为2.33、2、0.7mg/L和50mg/L时,在HRT=6 h、ORP=150mV和HRT=3 h、ORP=250 mV的条件下,出水中的TN、NH_4~+-N、PO_4~(3-)-P和COD_(Cr)的平均浓度分别为1.27、0.96、0.48 mg/L和25.76 mg/L,以及1.57、1.25、0.46 mg/L和29.6 mg/L,均能达到《城镇污水处理厂污染物排放标准》一级A排放标准(GB 18918—2002),反应器在进水水质波动较大的情况下脱氮除磷效果保持良好,有望实际应用至城镇污水处理厂。
        An immobilized Oedogonium brevicingulatum and active sludge symbiotic biofilm reactor was introduced, which was designed by referring to the secondary sedimentation tank in a certain municipal wastewater treatment plant.The treatment of total nitrogen(TN),ammonia nitrogen(NH_4~+-N),orthophosphate(PO_4~(3-)-P) and COD_(Cr) was evaluated under different hydraulic retention times(HRT), oxidation and reduction potentials(ORP) and water quality conditions.The results showed that when average concentration of TN, NH_4~+-N, PO_4~(3-)-P and COD_(Cr) in influents was 2.33, 2, 0.7 mg/L and 50 mg/L, respectively, average concentration of TN, NH_4~+-N, PO_4~(3-)-P and CODCr in effluents was 1.27, 0.96, 0.48 mg/L and 25.76 mg/L with 6h HRT and 150 mV ORP.Meanwhile, it was 1.57,1.25,0.46 mg/L and 29.6 mg/L with 3h HRT and 250 mV ORP.These treatments reached the corresponding first level A criteria specified in the Discharge Standards of Pollutions for Municipal Wastewater Treatment Plant(GB 18918—2002).Moreover, the reactor also exhibited a high adaptability with the variation of influent water quality, suggesting its application in real municipal wastewater treatment plant.
