Abstract:

The studying objectivesaimed to determined the nutrients removal ability from contaminated surface water byconstructed wetland technology for agricultural irrigation. The researching model was set up with two hydraulic loadings of 500mL/min/m2 (T1) and 1500mL/min/m2 (T2) to compare the nutrientstreatment efficiency bycommon reed (Phragmites australis). Post-treatment results at Loadings 1 and 2 were quite low in the levels of N-NH4+; N-NO3-; N-NO2-; and PO43-. In particular, the studying results of Loading 1 was greater than the Loading 2 and there was a significant difference (pvalue<0.05). In Loading 1, the nutrientsremoval efficiency were 95% (TP); 54% (PO43-); 74% (TKN); and 68% (N-NH4+), respectively. Therefore, the studying model showed the compatibility with the environmentally friendly trend and meeting the demand for sustainable development
