生物强化技术对水源地有机污染物的降解

利用两种新型PM和ACP材料进行生物强化技术降解水源地水体有机污染物的研究。通过对比不同的载体密度和水力停留时间来考察有机物降解效率的影响，中试结果表明：当载体密度为13．1％、停留时间为7d、原水C0DMn为4.69～6．93mg／L、UV254为0．057-0．121cm^-1,TOC为3．92-7．85mg／L的条件下，生物强化技术对CODMn、UV254、TOC的平均降解率分别达到21．35％、14．51％、34．63％，而对比空白池，对CODMn、UV254、TOC的平均降解率低至0．85％、0．94％、1．51％。可见利用生物强化技术能有效降解水源地水体的有机污染物，它对富营养化水源地水体的水质和生态系统有明显的改善作用。

REMOVAL OF ORGANIC POLLUTANTS BY BIOAUGMENTATION IN SOURCE WATER

Using two carriers named PM and ACP for bioaugmentation, organic pollutants in the source water can be removed. The study aims to investigate the effect of the removal of organic pollutants by bioangmentation. The results indicated that under the conditions that carrier density was 13.1% and HRT was 7d, CODMn in source water was 4.69 -6.93mg/L, and UV254, TOC was respectively 0.057-00.121 and 3.92-7.85mg/L, the removal rate of CODMn, UV254 and TOC reached to 21.35%, 14.51% and 34.63 % respectively. In the blank pool, the removal rate of CODMn, UV254 and TOC only reached to 0.85%, 0.94% and 1.51% respectively. It is evident that organic pollutants in source water could be significantly removed by bioaugmentation. The water quality and ecological system in eutrophic source water could be improved obviously by the technology.
