Analysis of the removal of BOD5, COD and suspended solids in subsurface flow constructed wetland in Latvia

Keywords: constructed wetlands, subsurface flow, BOD, COD, suspended solids
Abstract:

This study aims to evaluate the performance of subsurface flow constructed wetland in Latvia which was
established to receive storm water from surface runoff from a farmjard in agricultural area. As a part of this
study, subsurface horizontal flow wetlands was monitored, in order to evaluate the changes in the efficiency
of treatment depending on biological factors. The efficiency of horizontal subsurface flow constructed wetland
was evaluated by comparing the concentration of total suspended solids (TSS), biochemical oxygen
demand (BOD5) and chemical oxygen (COD) at inlet and outlet of the wetland depending on temperature and
pH. Since June 2014, water quality monitoring in a research site in the farm “Mezaciruli”, Zaļenieku parish,
Jelgava region has been carried out to treat the point source agricultural runoff from the impermeable pavements.
The analysis of the data obtained in the monitoring allows to draw conclusions about the influence of
certain factors in the subsurface flow constructed wetlands under the climate and environmental conditions
in Latvia.
