Do macrophytes play a role in constructed treatment wetlands

摘要: The larger aquatic plants growing in wetlands are usually called macrophytes. These include vascular plants, mosses and some algae. presence or absence of macrophytes is one the characteristics used to define wetlands, as such an indispensable component these ecosystems. As most important removal processes constructed treatment based on physical microbial processes, role has been questioned. This paper summarizes how influence wetlands. The functions relation wastewater effects gives rise to. stabilise surface beds, provide good conditions for filtration, prevent vertical flow systems from clogging, insulate against frost during winter, a huge area attached growth. Contrary earlier belief, growth does not increase hydraulic conductivity substrate soil-based subsurface wetlands. metabolism affects different extents depending type wetland. Plant uptake nutrients only quantitative importance low-loaded (surface systems). Macrophyte mediated transfer oxygen rhizosphere by leakage roots increases aerobic degradation organic matter nitrification. have additional site-specific values providing habitat wildlife making aesthetically pleasing.
