摘 要: 采用弹性填料曝气生物膜法对污染的河道水体进行处理的实验研究,结果表明,在2m/h的流速、水温为16℃~18℃、气水比为1:1的条件下,采用弹性填料的生物膜处理系统运转正常,不易发生堵塞或系统短流,系统此时的水力停留时间为3.5h左右,污水中的COD和NH3-N去除率稳定,其均值分别为49.4%和19.1%. The experiment study of polluted water in river with the biofilm process using elastic filling and micropore Aerator has been done with the research results which shows the biofilm treatment system with elastic filling operate smoothly and the system wouldn't be stopped up under the condition of temperature of 16℃-18℃ ,water speed of 2m/h,gas and water ratio 1 :1,at this time the HRT of the system is about 3.5 h, the average removal rate of COD and NH3--N in wastewater are 49.4%和19.1% in average.
