nitrogen removal efficiencies in constructed wetlands
abstract
this thesis summarizes the usage of constructed wetlands in reducing nitrogen
loaded anthropogenic waste water, sourcing a collection of results of outside literature.
the literature used in this thesis was found from scholarly websites. the purpose of this
study was to determine the most efficiently constructed wetland design in terms of its
nitrogen content removal, and to provide further insight into the new constructed
wetland technology. in this study the term efficiency is based on the nitrogen removal
rate determined by each data variable. wetland type / design and removal mechanism
were the attribute data collected and examined, all of which was found in the results of
prior literature. the two removal mechanisms used were denitrification / nitrification
and plant assimilation. the two-wetland types used in this study were surface flow
constructed wetlands and subsurface flow constructed wetlands. a one – way anova
was completed to determine the significant difference in nitrogen between the two
removal mechanisms, as well as the significant difference between the two wetland
designs. it was determined that there is no significant difference in nitrogen removal
between the removal types and wetland designs. insight and comparison with each
constructed wetland study were allowed for the results to be accepted. two scientific
rationalizations were discussed to further accept the results found. these rationalizations
included the overall performance of nitrogen removal and the secondary variables
related to the wetland design. it was concluded that further research is needed to further
comprehend this constructed wetland technology.
