| 1 | 活性氧化铝除氟研究显示文摘针对目前活性氧化铝饮水除氟中存在的问题,进行了生产性试验研究,通过采用原水投加CO_2气体降低pH值、小颗粒活性氧化铝、大流量短历时的NaOH循环再生法等新技术,提高了活性氧化铝的吸附容量和处理水的能力,克服滤料板结和假疲劳,除氟效果稳定可靠,水质好,再生时间短,用药省,降低了基建投资和运转费用。 | North China Municipal Engineering Design Institute A full-scale plant was set up for studying the existing problems on the fluoride removal from drinking water by activated alumina. Some new methods was adopted,such as the addition of CO2to reduce water pH value,the use of small-sized activated alumina,and the employment of a cyclic regeneration at large flow rate with NaOH as regenerant,which result in the improvement of adsorption capacity of activated alumina and treatment capacity, the elimination of the hardening of filtration materials and false fatigue,stable and reliable effectiveness,good quality in water,short regeneration time,small consumption of regenerant. And then the capital and openational costs were reduced. | 1989 | 中国给水排水1989，5，3： | 5 |
