This paper discussed the feasibility and advantage of the removal efficiency of low concentration sewage using three Stable Surface Flow Wetlands (SSFW) with bamboo splint and palm silk as substrates. Under the same hydraulic loading, the result of experiment indicated that the removal rate of COD,TP, TN were 73.97%, 61.42%, 28.98% respectively in SSFW with a bamboo splint substrate, and the corresponding removal rate of SSFW with a palm silk substrate were 78.37%, 69.42%, 24.4%; while substrate without a bamboo splint and a palm silk were 66.61%, 58.71%, 22.23%. The above information demonstrates that the removal efficiency of TN with a bamboo splint is better while the removal efficiency of COD and TP with palm silk is better. Bamboo splint and palm silk have their own advantages when they are applied to SSFW as substrate, which provide theoretical basis for the selection and matching of substrate.
