【摘要】：采用MBR處理石化廢水,研究不同曝氣方式對(duì)膜污染特征的影響。結(jié)果表明,當(dāng)曝氣強(qiáng)度分別為3.00、0.75、0.75-1.50和0.75-1.50-3.00 m~3/(m~2·h)時(shí),MBR達(dá)到設(shè)定的最大跨膜壓差20 kPa的時(shí)間分別為25.67、19.17、23.00、26.17 h,TMP的增長(zhǎng)速率K分別由1.26、0.82、1.32、0.95 Pa/s增大到5.45、5.43、5.52、3.34 Pa/s,MBR總處理水量分別為33.88、25.30、30.36、34.54 L。MBR對(duì)COD、TOC和氨氮的平均去除率分別為79.30%、75.04%、64.94%。由此可知,動(dòng)態(tài)曝氣方式(0.75-1.50-3.00 m~3/(m~2·h))能夠降低TMP增長(zhǎng)速率,緩解膜污染,延長(zhǎng)MBR運(yùn)行時(shí)間,增加總處理水量。
[Abstract]:The effects of different aeration modes on the characteristics of membrane fouling were studied by MBR. The results showed that when the aeration intensity was 3.00,0.75,0.75-1.50 and 0.75-1.50-3.00 m~3/ (m~2. H) respectively, the time for MBR to set the maximum transmembrane pressure difference of 20 kPa was 25.67,19.17,23.00,26.17 h, and TMP growth rate K was respectively. 0.95 Pa/s increased to 5.45,5.43,5.52,3.34 Pa/s, and the total amount of water treated by MBR was 33.88,25.30,30.36,34.54 L.MBR to COD, TOC and ammonia nitrogen, respectively, 79.30%, 75.04%, 64.94%., respectively. Therefore, the dynamic aeration mode (0.75-1.50-3.00 m~3/ (m~2.)) could reduce the growth rate, alleviate membrane pollution, prolong the running time and increase the operation time. The total amount of water is treated.
