Enhanced nitrification and denitrification in combined subsurface flow constructed wetland system
Name: Somanat Somprasert
keyword:
Combined constructed wetland
Abstract:
This study was performed to investigate a way to increase the system efficiencies by
evlaluating the reaction rate coefficients which are suitable for a tropical climate, as
in Thailand. The reaction rates of the COD degradation (kcoo), nitrification (kNitri),
and denitrification (kDenitri) were evaluated using a lab-scale compact-combined
constructed wetland system. Four concrete tanks, 0.5 x 1.0 x 1.0 m3 vegetated with
Cyperus flabelliformis Rottb., were used as lab-scale reactors. The effluent from the
biogas digester of pig farm wastewater was fed intermittently every 4 hours. The
hydraulic loading rates (HLRs) were varied at six rates 4, 6, 8, 10, 12, 16, and 20
cmd-I with 100% effluent recirculation to evaluate the reaction rate coefficients. The
COD and the nitrogen removal efficiencies were in the range of 72-87% and 67 to
94%, respectively. The nitrogen accumulation in plant tissue was in the range from
0.17 to 2.07 gNd-l. The plants in vertical flow bed should be cut every two or three
months to increase the nitrogen uptake rates. The reaction rate coefficients were
evaluated based on the dispersion model. The kcoo, kNitri and kDenitri were 0.33, 0.10
and 1.63 d-I for the horizontal flow bed and 1.09, 1.22, and 2.48 d-I for the vertical
flow bed. It was found that the system which fed to the vertical flow bed followed by
the horizontal flow bed (V-H system) enhances the nitrogen removal efficiency in a
combined constructed wetland system. The wastewater should be released
intermittently to increase the DO concentration in the beds.
