| 摘 要： | 对比了常规臭氧活性炭、中置臭氧活性炭、曝气活性炭滤池3种不同的工艺对北江顺德水道II～III类水质的净水效果。结果表明,曝气活性炭滤池采用0.2的气水体积比对CODMn的去除效果比常规、中置活性炭的处理效果要好,去除率达45.95%;中置臭氧活性炭工艺对UV254、TOC的去除效果最好,0.5 mg.L-1时去除率分别达66.36%、38.99%;曝气活性炭滤池对于高含量氨氮的去除效果明显优于常规、中置臭氧活性炭滤池,0.4的气水体积比时氨氮去除率达99.43%,出水达到GB 5749-2006要求。

| Abstract: | The purification effect of treating Beijiang source water in conventional O3-BAC and mid-positioning O3-BAC and aeration-BAC process were compared.Studies show that: removal effect of CODMn in aeration-BAC with aeration gas-water ratio 0.2 was better than that of in conventional O3-BAC and mid-positioning O3-BAC,the average removal rates of CODMn was 45.95%.UV254 and TOC got best removal effect in mid-positioning O3-BAC with 0.5 mg·L-1 ozone,removal rates was 66.36% and 38.99% respectively.Removal effect of high concentration of NH4+-N is much better in aeration-BAC than that of in the other two processes,removal rates of NH4+-N was 45.95% when aeration gas-water ratio was 0.4,and the water reached The health standard of living and drinking water. |
