摘　　要：采用臭氧-生物沸石工艺,对微污染模拟水源水进行微生物挂膜和驯化。结果表明,生物沸石柱采用接种挂膜法,在水温17～19℃,经过17 d挂膜成熟。挂膜期间COD和氨氮的去除率在到达最低点和稳定值的时间上具有同步性,挂膜成熟后COD的去除率稳定在40%左右,氨氮的去除率稳定在70%左右。在臭氧存在的条件下,微生物仍能生存,微生物经过2～3 d的驯化,在臭氧投加量为2.1 mg·L-1、接触时间10 min时,COD和氨氮的去除率均较高。The combination processes of Ozone （03） combination with biological Zeolite was used in the test of the treatment of micro-polluted water, and the start-up was studied. The results showed that： Used inoculation method, the biofilm of the biological zeolite column matured after 17 d, at a temperature of 17-19℃. During the days of film formation, COD and ammonia nitrogen removal rate reached the lowest point of the curve and stabilize with the synchronization, when biofilm Matured, the COD removal efficiency stabilized at about 40% and the ammonia nitrogen removal rate stabilized at around 70% .The cultured microbes found to be exist in the conditions of Ozone （03）. After 2-3 d of domestication of micro-organisms, the removal efficiencies of COD and ammonia nitrogen were good when the ozone dosage was 2.1 mg·L^-1 and contact time was10 min.
