提出了一种新的除氟方法，即铝铁床除氟，对该方法的除氟性能进行了试探性研究，比较了不同停留时间对除氟效果的影响，实验结果表明，在EBCT＝8 h时，氟的去除率最大，可达到77.1%，但随着反应时间的增长，去除率随之下降，简单的水力冲洗对铝铁床的除氟性能有一定的再生作用。%The paper introduces the new method for removing fluorine method,the aluminum iron berth,undertakes the investigative research on its removing fluorine performance,compares the different dwell time on the removing fluorine effect,proves by the experiment result that the re-moval ratio is the highest,77. 1%,when EBCT is 8 h,however,the ratio falls along with increasing reaction time,and hydraulic clearing has certain regeneration role in the removing fluorine performance.
