In this paper, a novel patent intermittent aeration vertical flow constructed wetland (IA-VFCW) was developed, and the influences of salinity on the microbial community of IA-VFCW were investigated. The experimental results showed that bacterial communities at the genus level were transited along with the salinity varied from 0‰ to 20‰. Ferritrophicum and Psychrobacter show an increasing tendency and the maximum abundance was 14.8% and 9.8%, respectively. As salt concentration was increased, Cyanobacteria was gradually disappeared. A total of 8 samples were carried out by microbiology, ten different genera were associated with the removal of nitrogen which included as follows: Halomonas , Thiobacillus , Cyanobacteria , Denitratisoma , Arcobacter , Acinetobacter , Sulfurimonas , Nitrosomonas , Dechloromonas and Hydrogenophaga .
