【摘要】 采用处理量为0.08m3/h的一体式膜生物反应器处理城市生活污水。实验结果表明:0.073MPa的操作压力下,膜通量能维持在0.02m3/(m2·h)这一较高的水平,且此时的最佳曝气量为150L/min。实验出水水质稳定且优于生活杂用水回用标准,可直接回用。更多还原

【Abstract】 In the paper,an experiment is made to investigate the mechanism of urban domestic wastewater treatment by utilizing the submerged membrane bioreactor with the processing rate of (0.08　m~3/h.) The experiment results show that the optimal transmembrane pressure is 0.073 Mpa under which the membrane flux can be maintained at the higher level of 0.02 m~3/(m~2·h) and the optimal aeration rate is found to be 150 L/min. Under the above conditions,the effluent quality is stable and better than the water quality standard for reuse issued by the Ministry of Construction of China.更多还原
