摘要:
针对天津市引滦水中2-甲基异莰醇（2-MIB）超标引起的水源水嗅味问题，开展了常规混凝沉淀、氧化、粉末活性炭（PAC）吸附以及预氧化联合PAC强化混凝沉淀工艺去除引滦水中2-MIB的研究。结果表明，混凝沉淀、氧化、PAC吸附对不同形态的2-MIB有不同的作用效果，但这3种单一技术并不能有效去除水中的2-MIB；NaClO/KMnO4/O3+PAC+混凝沉淀组合工艺对引滦水中的2-MIB均有较好的去除效果，其中O3+PAC+混凝沉淀组合工艺的处理效果最佳。另外，结合现场实际情况，开展了NaClO与PAC联用技术的实际应用研究，发现NaClO+PAC+PAC（PAC分两点投加）对2-MIB有很好的去除效果，保证了天津市冬季引滦供水安全运行，可以为后续应对引滦水中2-MIB污染提供借鉴。
Abstract:
The conventional coagulation-sedimentation, oxidation, powdered activated carbon (PAC) adsorption and pre-oxidation combined with PAC enhanced coagulation-sedimentation were employed for the removal of 2-methylisoborneol (2-MIB) in water from Luanhe Diversion Project in Tianjin, so as to solve the odor problem caused by excessive 2-MIB in water. Coagulation-sedimentation, oxidation and PAC adsorption showed different removal effect for different forms of 2-MIB, but 2-MIB could not be effectively removed by these three single technologies. The NaClO/KMnO4/O3+PAC+coagulation-sedimentation combined process demonstrated good removal effect for 2-MIB in water from Luanhe Diversion Project, among which the O3+PAC+coagulation-sedimentation process was the best. Combined with the field situation, the NaClO and PAC combined process was employed in practical application, and the NaClO+PAC+PAC process (PAC was added in two positions) demonstrated a good performance for removal of 2-MIB in water from Luanhe Diversion Project, which ensured the safe operation of water supply in winter of Tianjin, and provided reference for dealing with 2-MIB pollution in water from Luanhe Diversion Project.
