摘要:
采用常规处理/臭氧/生物活性炭、超滤/臭氧/生物活性炭与超滤/纳滤3种不同工艺处理太湖高藻原水，通过中试比较3种工艺对水体中污染物的去除效能，并从三维荧光光谱和有机物分子质量两方面研究了不同工艺对有机物的去除机理。结果表明，超滤/臭氧/生物活性炭组合工艺对浊度、UV254、藻密度和叶绿素a的去除效果最好，平均去除率分别为99.96%、96.40%、99.39%和98.75%；超滤/纳滤组合工艺对CODMn的平均去除率最高，为92.73%；常规处理/臭氧/生物活性炭组合工艺对氨氮的平均去除率最高，为84.21%。在线混凝可有效控制膜污染，保证系统的长期稳定运行；3种工艺在污染物去除方面各有优势，但膜组合工艺的处理效果更稳定。
Abstract:
Algae-laden raw water from Taihu Lake was treated by three different combined processes (conventional treatment/O3/BAC, UF/O3/BAC and UF/NF), the removal efficiency of pollutants in water by three different processes was compared by a pilot-scale test,and the removal mechanism of organic matter was investigated through three-dimensional fluorescence spectrum and molecular weight of organic matters. UF/O3/BAC process had the highest average removal rates of turbidity, UV254, algae density and chlorophyll-a, which were 99.96%, 96.40%, 99.39% and 98.75%, respectively. UF/NF process had the highest average removal rate of CODMn(92.73%),while conventional treatment/O3/BAC process had the highest average removal rate of ammonia nitrogen (84.21%). Online coagulation could effectively control membrane fouling and ensure long-term stable operation of the system.The three processes had their own advantages in pollutants removal, but the membrane combined process was more stable.
