摘要
采用生物沸石预处理器,对微污染水源水中污染物的去除有较好的效果.经长期运行测试,该反应器在最佳滤速为8 m/h时,对氨氮平均去除率为92.4%,对亚硝酸盐氮的平均去除率为 90%,对有机物的(CODMn)平均去除率为30.4%.
A pollutant removal of good effect was studied in micropolluted water source by using pretreatment reactor of biological zeolite. After a longterm operation,it was obtained that the average removal efficiency of NH_3-N was 92.4%,while 90% for NO^-_2-N,and 30.4% for organic compounds COD_(Mn) if the reactor was at the optimal filtering velocity of 8 m/h.
