Abstract: The study aims to assess the applying effectiveness of constructed wetland technology for polluted surface water treatment. The experimental models were operated with 2 hydraulic loadings of 500mL/min/m2 (T1) and 1500mL/min/m2 (T2). The reed grass (Phragmites australis) was selected for the studying process. The surface water resource was removed from the pollutant components (TSS, BOD5, 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/m2 is higher than the loading of 1500mL/min/m2, especially in the reed planting trial. In particular, the treatment efficiency of pollutants such as TSS, BOD5, 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.
