摘要

  • 摘要: 为了考察膜生物反应器(MBR)净化受污染地表水自然启动过程中功能菌群的成熟规律及碱度对MBR去除水中氨氮的影响,通过构建小试规模的MBR,考察了MBR处理受污染地表水的自然启动和稳定运行除污染特性。结果表明,MBR在自然启动过程中不会出现异养菌成熟的标志,系统对进水DOC、UV254和CODMn的平均去除率分别仅为(14.5±5.1)%、(12.6±5.6)%和(31.2±7.4)%,应考虑将其他工艺与MBR联用以提高系统的有机物去除能力。启动23天后,MBR中的亚硝化细菌成熟,NH3-N去除率达到80%以上;启动31 d后,MBR中的硝化细菌成熟,出水NO2--N稳定在0.05 mg/L以下。碱度对MBR去除NH3-N效能影响较大,向进水中投加30 mg/L的NaHCO3能使MBR对NH3-N的去除率由(86.1±3.7)%提高至(98.0±1.6)%。在连续曝气、10 L/(m2·h)通量、每10 min反洗15 s运行模式下,MBR的膜污染较为严重,平均TMP增长速率为0.45 kPa/d,需进一步优化相关参数以实现MBR的长期稳定运行。
    Abstract: A bench scale membrane bioreactor (MBR) was constructed for investigating the pollutants removal characteristics of natural start-up and steady operation of MBR for treating polluted surface water. During the experiments, there was no clear indication for the maturity of heterotrophic bacteria, and the removal efficiencies for DOC, UV254 and CODMn were only (14.5±5.1)%, (12.6±5.6)% and (31.2±7.4)%, respectively. Therefore, the MBR need to be coupled with other processes to improve its capacity for removal of organic matter. However, the indications for the maturity of nitroso-bacteria and nitro-bacteria were visible. Respectively, the nitroso-bacteria came to mature 23 days after start-up and nitro-bacteria came to mature 31 days after start-up. During the steady state, the removal of influent NH3-N was over 80% and the effluent NO2--N was bellow 0.05 mg/L. Besides, the results of ammonia removal demonstrated that the alkalinity had significant influence on the performance of MBR for ammonia removal, and the removal efficiency of ammonia increased from (86.1±3.7)% to (98.0±1.6)% while dosing 30 mg/L of NaHCO3 in influent. In the investigation, the membrane in MBR was operated under the conditions of constant flux (10 L/(m2·h)), continuous aeration and backwashing for 15 s after every 10 min of filtration. Under these conditions, obvious membrane fouling was observed, with the average trans-membrane pressure development rate of 0.45 kPa/d. To mitigate the membrane fouling of MBR, it is required to further optimize the relevant operating parameters.
