Abstract
Using plant material as an additional carbon source is an economical and effective way to enhance nitrogen removal in wetlands. In this study, the reed straw was crushed and then added to the middle layer of the vertical down-flow wetland to investigate the effect of reed straw dosing on the removal of various forms of nitrogen from micro polluted waters in wetlands. The results showed that the addition of reed straw increased the content of organic matter in the wetland and significantly improved the removal of NO3−-N and NO2−-N from the wetland. When the dosage of reed straw was 16.7 g/kg, the wetland nitrogen removal effect was best, the removal rates of NH4+-N and NO3−-N reached 85.72% and 87.10%, and there was no accumulation of NO2−-N. The addition of reed straw decreased the NO3−-N content and nitrification rate in the substrate and increased the NH4+-N content and denitrification rate. Adding cheap reed straw can provide organic carbon for wetlands and greatly improve the removal of NO3−-N.
