摘　　要：基于武汉白鹤嘴水厂现有净水工艺,搭建三种不同活性炭层高度(600、700、800 mm)的炭砂滤池中试系统,对比研究炭砂滤池与V型滤池的处理效果。研究结果表明:三种炭砂滤池的处理效果没有显著差异;所有炭砂滤池和V型滤池均可有效降低出水浊度(<0.6 NTU),但炭砂滤池出水浊度更加稳定;炭砂滤池对CODMn、UV254、TOC的平均去除率相对于V型滤池分别提高了40.7%、65.7%和36.1%,此外炭砂滤池出水中具有荧光特性的有机物浓度也显著低于V型滤池。为了进一步评估炭砂滤池去除嗅味物质的效果,同时向炭砂滤池进水中投加硫酸铵、土臭素和二甲基异莰醇,当水体中氨氮浓度为0.46~3.20 mg/L,土臭素浓度为5~40 ng/L,二甲基异莰醇浓度为15~50 ng/L时,炭砂滤池出水氨氮去除率总体可达50%以上,而各炭砂滤池出水中均难以检出土臭素和二甲基异莰醇。Based on the existing water treatment process at the Baihezui Water Plant in Wuhan,a pilot-scale system was established using effluent from the sedimentation tank as influent.Three granular activated carbon(GAC)–sand filters with activated carbon layers of 600,700,and 800 mm were constructed to compare their performance with that of a V-filter.No significant difference was observed among the three GAC–sand filters,and all consistently reduced effluent turbidity to below 0.6 NTU.However,the GAC–sand filters provided greater turbidity stability compared to the V-filter.Regarding organic matter removal,the GAC–sand filters improved the average removals of permanganate index(CODMn),UV254,and total organic carbon(TOC)by 40.7%,65.7%,and 36.1%,respectively,relative to the V-filter.Additionally,fluorescent organic matter in the GAC–sand filter effluent was substantially lower than in the V-filter effluent.To evaluate odor-compound removal under algal conditions,ammonium sulfate,geosmin(GSM),and 2-methylisoborneol(2-MIB)were introduced into the GAC–sand filter influent.In the presence of 0.46~3.20 mg/L ammonia nitrogen,5~40 ng/L GSM,and 15~50 ng/L 2-MIB,the GAC–sand filters removed more than 50%of ammonia nitrogen and nearly completely eliminated both GSM and 2-MIB.
