摘要:: 针对我国高寒牧区水源水间歇式、偶发性污染物超标问题，研发了以电-生物耦合慢滤为核心的处理技术，并将其用于处理高寒牧区融雪水，探究其对常规污染物的去除效果，同时采用三维荧光光谱分析了其对有机物的去除机理。结果表明，电-生物耦合慢滤装置在5 V电压下挂膜时间为28 d，较传统生物慢滤装置缩短了7 d；在水温为5~15 ℃、滤速为0.2 m/h、电压为10 V的工况下，电-生物耦合慢滤装置对高寒牧区融雪水中浊度、COD_Mn、NH₄⁺-N、UV₂₅₄的平均去除率分别为97.66%、61.11%、91.67%、72.94%，相比传统生物慢滤装置，COD_Mn、NH₄⁺-N、UV₂₅₄去除率分别提高了36.38%、39.63%、38.20%；电-生物耦合慢滤装置对进水中4个主要荧光峰的荧光强度分别削减了36.67%、66.22%、67.08%、69.76%，实现了对色氨酸类蛋白质、富里酸和胡敏酸类腐殖质的有效去除。

Abstract:: Aiming at the issue of intermittent and occasional pollutant exceeding standard in source water in alpine pastoral area in China, a treatment technology based on electro-biological coupling slow filtration was developed and implemented for the treatment of snowmelt water in alpine pastoral area to explore its removal efficacy on conventional pollutants, and its removal mechanism of organic matters was analyzed through three-dimensional fluorescence spectrum. The biofilm formation time of the electro- biological coupling slow filter was 28 days at a voltage of 5 V, which was 7 days shorter than that of the traditional biological slow filter. The average removal rates of turbidity, COD_Mn, NH₄+-N and UV₂₅₄ were 97.66%, 61.11%, 91.67% and 72.94%, respectively, at water temperature of 5-15 ℃, filtration speed of 0.2 m/h and voltage of 10 V. Compared with traditional biological slow filter, the removal rates of COD_Mn, NH₄⁺-N and UV₂₅₄ were elevated by 36.38%, 39.63% and 38.20%, respectively. The fluorescence intensity of the four major fluorescence peaks in the influent was decreased by 36.67%, 66.22%, 67.08%, and 69.76%, respectively, indicating that the removal of tryptophan protein, fulvic acid, and humic acid was effectively achieved by the electro?biological coupling slow filter.
