摘要:
为探究曝气吹脱原位控制水源水库中2-甲基异莰醇（2-MIB）和土臭素（GSM）的效能与影响因素，采用配水和水库原水开展了小试研究。结果表明，曝气头孔径、单位面积曝气量和温度是影响曝气吹脱去除嗅味物质效率的主要因素，在曝气头孔径为5 μm、曝气量为2.830 L/（min·m2）、温度为25 ℃条件下曝气48 h后，对2-MIB及GSM的削减率分别达到81.7%和84.3%。对于水库原水，曝气吹脱除了直接去除水中游离态的2-MIB外，还通过抑制藻类及放线菌等产嗅微生物的繁殖实现对水体中2-MIB的削减，与无曝气对照组相比，25 ℃下曝气吹脱对原水中2-MIB的削减率达到88.5%。初步经济性分析表明，水库原位曝气吹脱控制嗅味物质的运行成本仅为0.042元/m3，远低于水厂内应急处理。
Abstract:
To investigate the effectiveness and influencing factors of aeration stripping for the in-situ control of 2-methylisoborneol (2-MIB) and geosmin (GSM) in water source reservoirs, a bench-scale study was conducted using synthesized water and reservoir source water. The results showed that the aerator head aperture, aeration flow rate per unit area, and temperature were the primary factors influencing the efficiency of aeration stripping in removing odor-causing substances. Under conditions of a 5 μm aerator head aperture, an aeration rate of 2.830 L/(min·m2), and a temperature of 25 ℃, 48 hours of aeration resulted in reduction rates of 2-MIB and GSM by 81.7% and 84.3%, respectively. For reservoir source water, aeration not only directly removed the dissolved 2-MIB in the water but also inhibited the growth of odor-producing microorganisms, such as algae and actinomycetes, thus reducing 2-MIB in the water. Compared to the non-aeration control group, aeration at 25 ℃ achieved a reduction rate of 88.5% for 2-MIB in the raw water. Preliminary economic analysis indicated that the operational cost of in-situ aeration stripping for controlling odor substances in the reservoir was only 0.042 yuan/m3, significantly lower than the emergency treatment costs at the water treatment plant.
