This study set three folds stable surface flow wetlands (FSSFWs) with the substrate depth of 15cm, 20cm and 25cm, and compared the removal efficiencies of COD, TN, TP, NH3-N and SS of every FSSFW. The results showed that the removal efficiency of FSSFWs increased gradually with deepening the depth of the substrate. The content of the organic matter in the distribution zone was higher than the follow-up zones. The substrates contained calcium and aluminum oxides which might form phosphate attached to the substrate, as a result of raising the content of P in the sludge. The results indicated that the substrate depth had a positive influence on the removal efficiency of FSSFWs.
