| Abstract: | Based on the ecology theory, through controlling the effective height of wetland substrate, promoting plant roots development and enhancing purification of biological synergy effect, following conclusions were drawn： When the depth of cinder substrate is different, the purification ability of the installment is dissimilar. When the depth is 30 cm or 40 cm, the sewage purification ability is better, simultaneously, the side of root is stronger, the total biomass of root and the ratio surface area are 101.7 g and 612.6 m2/m3 respectively. |
