The experimental models were operated with 2 hydraulic loadings of 500mL/min/m 2 (T1) and 1500mL/min/m 2 (T2). The reed grass ( Phragmites australis ) was selected for the studying process. The surface water resource was removed from the pollutant components (TSS, BOD 5 , COD) and harmful microorganisms (fecal coliform) which aim to protect the water quality and aquatic ecosystems. The results showed the treatment effectiveness of loading of 500mL/min/m 2 is higher than the loading of 1500mL/min/m 2 , especially in the reed planting trial. In particular, the treatment efficiency of pollutants such as TSS, BOD 5 , COD reached a high rate of 85%, 90%, and 87%, respectively. In addition, ANOVA statistical analysis showed the effectiveness of water quality parameters belong to two loadings were statistically significant (P<0.05). Thus, the surface water pollutant removal by subsurface vertical flow constructed wetland technology could be contributed to promoting the sustainable agricultural development. Keywords: Constructed wetland, removal, surface water, Phragmites australis , pollution. References : [1] Z. ElZein, A. Abdou, I.A.
