| Abstract: | Objective] To obtain the optimum operating parameters of the horizontal subsurface flow constructed wetlands.Methods] This research studied the treatment effect of the horizontal subsurface-flow constructed wetlands in different conditions on low-concentration sewage in the North,investigated the relationship between the removal rate of CODCr,NH4+-N,TN and TP and the temperature,hydraulic loading.Result] When the hydraulic loading was 0.04-0.15 m3/(m2·d),high hydraulic loading in summer(0.12-0.15 m3/(m2·d)),middle hydraulic loading in autumn(0.07-0.10 m3/(m2·d)),low hydraulic loading in winter(0.04-0.06 m3/(m2·d)) were the optimum operating parameters.Conclusion]The temperature was one of the key factors on treatment effect. |
