摘要
采用接触氧化法和陶瓷膜相结合设计制备了无机膜生物反应器、在温度10～28℃、pH〉6．5、HRT（水力停留时间）8h、SRT（污泥停留时间）130h、MLSS（混合液悬浮固体浓度）10．2g／L、膜面流速5．0～7．0m／s，膜操作压力0．20MPa的条件下处理生活污水，膜通量为：130～170L／（h·m2），HLS-无机膜生物反应器对COD的去除率可达99％以上．出水NH3-N为3～6mg／L，浊度为3～8NTU．
A membrane bio - reactor（MBR） was designed and used by contact oxidation process with membrane separation. Domestic wastewater was treated by the MBR process at 10--28℃, pH〉6.5, HRT 8 h, SRT 130 h,MLSS 10.2 g/L and the cross flow velocity of 5.0--7.0 m/s, pressure of 0.20 MPa. The membrane flux is 130--170 L/（h·m2）, the removal of COD by the reactor is more than 99%. The concentration of NH3- N in outflow water 3--6 mg/L and the tubidity 3--8 NTU.
