摘　　要：以新型臭氧/生物活性炭给水深度处理工艺中试为基础,将生物炭滤池置于沉淀池与砂滤池之间,对升流式与降流式炭滤池处理微污染水的效果进行对比分析。结果表明,采用陶粒-活性炭双层填料的炭滤池,升流式由于首先经过陶粒层而使整个活性炭层处于浊度相对较低的环境中,更利于发挥活性炭吸附作用,同时表现出较高的有机物去除率;升流式炭滤池较降流式炭滤池的水头损失低、增长速率慢,运行更为稳定,出水中微型生物的数量也大幅减少。另外,由于有砂滤池殿后,出水浊度和微型生物等无需严格控制,可对其曝气,对氨氮的去除能力较之于传统后置生物活性炭滤池有大幅度的提高。Based on a new O3/BAC advanced water treatment process, the BAC filter was placed between the sedimentation tank and the sand filter, to make a comparison of purification effect on micro- polluted water between upflow and downflow BAC filters. The results showed that with double ceramsite- activated carbon packing filter, the upflow BAC filter was in low turbidity environment as water first pas- sed the ceramsite layer, which was beneficial for carbon adsorption and showed high organics removal rate. Compared with downflow BAC filter, the upflow BAC filter had other advantages, such as lower head loss, slower growth rate, more stable operation and fewer microorganisms in the effluent. With the sand filter behind, strict control of the effluent turbidity and microorganisms was not necessary, and aera- tion was allowed. By aeration, the upflow BAC filter presented a large increase in ammonia nitrogen re- moval rate compared with traditional post-positioning BAC filter.
