Construction of a Landscaping-type Wetland System for Wastewater Treatment and Analysis of Plant Denitrifying Effect
景观型人工湿地污水处理系统构建及植物脱氮效应研究

A pilot landscaping-type wetland system for wastewater treatment was constructed by introduction of 15 selected ornamental plant species(including 4 terrestrial plant species).The pilot system consists of 2 sequenced treatment units and 12 sub-units,i.e.,a primary treatment unit with 4 parallel cells and a secondary treatment unit with 8 subsurface flow cells.Designed experiments were conducted in the established system to investigate the characteristics of nitrogen accumulation in different plants and the ...
