- 摘要:
- 针对原水中2-甲基异莰醇（2-MIB）和土臭素（GSM）两种典型嗅味物质带来的饮用水水质问题，采用新型吸附剂开展了2-MIB和GSM的强化去除应用研究，探究了吸附剂加料方式（湿法或干法）、投加量、腐殖酸浓度对2-MIB和GSM去除效果的影响，并验证了实际应用效果。结果表明，新型吸附剂湿法加料方式对2-MIB和GSM的去除效果更好；随着吸附剂投加量的增加，对2-MIB和GSM的去除率均呈现增加趋势，当投加量超过10.0 mg/L时，对两种污染物的去除率均超过80%；水中腐殖酸等有机物浓度对2-MIB和GSM的去除效果有一定影响，但整体上可控。在辽宁某净水厂原水GSM浓度高达400~600 ng/L时进行了应急处理，并取得了理想效果。
- Abstract:
- A novel adsorbent was applied to enhance the removal of two typical odor?causing compounds including 2-methylisoborneol (2-MIB) and geosmin (GSM) to address drinking water quality issues arising from these two substances in raw water. The influence of key operational parameters, including adsorbent dosing method (wet vs. dry), dosage, and humic acid concentration, on the removal efficiency of 2-MIB and GSM was systematically investigated, and the practical applicability of the approach was experimentally validated. The wet dosing method employing the novel adsorbent demonstrated a more effective removal performance for 2-MIB and GSM. As the adsorbent dosage increased, the removal efficiencies of both compounds exhibited a consistent upward trend. When the dosage exceeded 10.0 mg/L, the removal efficiencies for both compounds surpassed 80%. The presence of organic compounds in water, such as humic acid, exerted a moderate influence on the removal efficiency of 2-MIB and GSM; however, this interference remained generally within acceptable limits. Emergency treatment measures were implemented upon detecting a GSM concentration in the raw water of a water purification plant in Liaoning Province ranging from 400 ng/L to 600 ng/L, resulting in favorable outcomes.
