摘　　要：针对我国西北地区集雨窖水污染现状,在对粗滤/生物慢滤水质净化技术进行系统的实验室研究、技术优化及集成的基础上,将该技术在西北干旱村镇地区进行了工程化应用。结果表明,粗滤/生物慢滤水质净化技术能有效处理集雨窖水,对常见的污染物指标均有很好的去除效果。在粗滤/慢滤设备滤速为0.2 m/h的情况下,生物膜的生长周期为40 d左右。生物膜形成后,平均出水浊度、COD Mn、氨氮分别为0.8 NTU、2.5 mg/L、0.47 mg/L,平均去除率分别为90%、34%、31%,出水水质满足国家饮用水水质标准的要求。该技术无需投加任何药剂、操作管理方便,适用于西北干旱村镇地区集雨窖水的水质安全处理。Due to the current water pollution situation in rainwater harvesting pits in northwest China, a rough and slow filtration process was applied in arid rural parts of this area following research, technology optimization and integration. The results showed that this process could effectively remove common pollutants from water in rainwater harvesting pits. When the filtering velocity of the process was controlled at 0.2 m/h, the biofilm growth period was about 40 d. After biofilm formation, the average turbidity, CODM, and ammonia nitrogen in the effluent were 0.8 NTU, 2.5 mg/L and 0.47 mg/L, and the average removal rates were 90% , 34% and 31% respectively, meeting the requirements of national drinking water standards. Due to no need for chemicals and convenient operation and management, this water treatment process was applicable in rainwater harvesting pits in arid rural areas of northwest China.
