| Abstract: | [Objective] The aim was to study the purification effect of A/O process on pollutants.[Method] Using A/O process as pretreatment of constructed wetland,the influence of the hydraulic retention time(HRT) and internal return rate on contamination removal effects were studied.[Result] The results showed that the COD removal efficiency at 15 ℃ could reach 60% when the HRT and internal return rate were 3.4 h and 1.0.[Conclusion] The effluent concentration of COD met the second standard of wastewater treatment plant effluence(GB18918-2002),so it reached the demand of post treatment using constructed wetland. |
