title: [Advances in the research of infiltration wetland wastewater treatment systems].
abstract: As their high purification efficiency and relatively low capital investment and treatment cost, infiltration wetland wastewater treatment systems have been popular, and are being increasingly applied in many countries. In this paper, the bed structure and filtering media, nitrogen and phosphorus removal processes and purification mechanisms, performance, current design criteria, operation and regulation mechanisms, soil clogging problem and solutions, and combination of vertical-horizontal flow wetlands treatment system and its use in different types of wastewater treatment were introduced and summarized. Finally, the future research directions of this technique were also discussed.
