英文摘要 | Enhancing the treatment efficiency of livestock wastewater by effluent recirculation is investigated in a pilot-scale vertical-flow constructed wetland. The wetland system is composed of downflow and upflow stages, on which narrow-leaf Phragmites communis and common reed Phragmites typhia are planted, respectively; each stage has a dimension of 4 m2 (2 m × 2 m). Wastewater from the facultative pond is fed into the system intermittently at a flow rate of 0.4 m3 /d. Recirculation rates of 0, 25%, 50%, 100% and 150% are adopted to evaluate the effect of the recirculation rate on pollutants removal. This shows that with effluent recirculation the average removal efficiencies of NH |
