China Environmental Science, 2016,36(12)：3601~3609 Abstract ：Zeolite trickling filter (ZTF) was developed to treat domestic wastewater. Biofilm colonization and the effects of hydraulic loading rate (HLR) on the treatment of domestic wastewater by the ZTF were investigated. In biofilm colonization stage, the influent was set as the “continuous manner”, and after 26d, COD and ammonia removal efficiencies reached 85% and 68%, even more, respectively, moreover, relative deviation of the two adjacent test results of COD and ammonia were less than 10% in this period, indicated that the biofilm colonization was success and the ZTF reached a stable operation state. The ZTF e
