Nitrogen Removal from Contaminated Water by Two Aquatic Plants

Abstract:

Two aquatic macrophytes (Monochoria korsakowii and Alisma plantago-aquatica) were grown in monoculture to test the relative growth rate(RGR) and abilities of removing total nitrogen(TN) by the manipulative indoor experiment. A nutrient treatment consisted of two levels of nitrogen[ low (14 mg L-1 N) and high (56 mg L-1 N) ]of nutrient solution. Result revealed that the RGR of the species was significantly different, however nutrients had no significant affect on the RGR. The results showed that TN in wastewater were significantly higher from unvegetated microcosms compared to vegetated. M. korsakowii was shown to be best removal effect with the removal rates of 94.9% and 77.0% at low and high concentrations of TN.
