  • 摘要: 利用玻纤管作为膜组件材料制作了一套动态膜生物反应器（DMBR），并结合A/O工艺组成DMBR -A/O污水处理装置，研究了其在全程硝化反硝化（阶段I）和短程硝化反硝化（阶段II）条件下对生活污水的处理效果、膜污染状况及恢复膜通量的措施。结果表明：当运行通量为15 L·（m2·h）-1时，阶段I可连续运行15 d，而阶段II可连续运行30 d；水力停留时间为8 h时，阶段I、II对COD、NH4+-N去除率均大于85%，差别不明显，但对TN的去除率分别为58%和75%。因此，与全程硝化反硝化相比，短程硝化反硝化可显著缓解膜污染，并可显著提高脱氮效率。此外，被污染后的膜组件经水力冲洗和0.05%NaClO溶液浸泡12 h后，几乎能够完全恢复膜组件性能。
    Abstract: With glass fiber tubes as membrane material, a set of dynamic membrane bioreactor-anaerobic/oxidic sewage treatment device (DMBR-A/O) was constructed, and the performance of the device for sewage treatment was researched under full nitrification/denitrification (stage I) and shortcut nitrification/denitrification (stage II) conditions, respectively. The results showed that stage II had been continuously running for 30 d while stage I was only 15 d with the membrane flux of 15 L·(m2·h)-1. And the average removal rates of COD, NH4+-N were above 85% for both the two stages with unobvious differences under HRT 8 h. However, the average TN removal rate of stage I and stage II were 58% and 75%, respectively. Therefore, it is indicated that shortcut nitrification/denitrification technology was obviously effective for membrane pollution mitigation and TN removal. In addition, the performance of fouled membrane component could be almost completely recovered by hydraulic cleaning and soaking with 0.05% NaClO solution for 12 h.
