| 摘 要： | 针对原水污染严重的实际情况,开展了以臭氧、高锰酸钾和粉末活性炭的组合预氧化工艺强化生物活性炭滤池去除嗅味、CODMn、氨氮等的生产性试验.当原水的CODMn和氨氮浓度分别为7.0、3.0 mg/L时,出水浓度分别为3.0、0.5 mg/L,且出水无嗅味.同时试验结果还表明,对CODMn的去除主要发生在预氧化过程中,生物活性炭滤池主要靠生物吸附和活性炭吸附去除CODMn.

| Abstract: | As raw water is terribly polluted,a full-scale experiment was carried out.The removals of odor,COD_(Mn) and ammonia nitrogen were enhanced by the process of combined preoxidation in biofiltration,which contains ozone,potassium permanganate and powdered activated carbon(PAC).When the concentrations of the COD_(Mn) and ammonia nitrogen in raw water are 7.0 mg/L and 3.0 mg/L respectively,their concentrations in treated water are 3.0 mg/L and 0.5 mg/L,respectively.At the same time,the results also show that COD_(Mn) is removed mainly in the progress of preoxidation,while the removal of COD_(Mn) in biofiltration depends on the adsorption of biological activated carbon. |
