| Abstract: | In this study, the combined process of high-rate activated sludge (HiCAS)-vertical subsurface flow constructed wetland (VSFCW) was used to treat wastewater, containing aerobic biochemical tank (28 L) and constructed wetland (65 cm×65 cm×40 cm). The wastewater treatment performance and resource recovery potential of the combined process were evaluated under the conditions of hydraulic retention time (HRT) of 1 h, sludge retention time (SRT) of 0.2 d, hydraulic loading of 4.08 m3·(m2·d)−1, sludge loading of 0.973 kg·(kg·d)−1, continuous jet aeration (12 L·min−1) and (30±2) ℃. The results showed that when the average initial concentrations of COD, ammonia nitrogen and total phosphorus were 306.16, 30.24 and 5.32 mg·L−1, respectively, the average COD removal efficiency by HiCAS was 38.6%, and each kilogram oxygen-demanding organics removal (as COD) produced 0.85 kg dry sludge, indicating high organic carbon enrichment and digestion capacity potential. Meanwhile, the HiCAS-VSFCW system had significant effects on the removal of COD, ammonia nitrogen, total nitrogen, total phosphorus, with the average removal efficiencies of 83.7%, 68.3%, 76.1% and 86.5%, respectively. The concentrations of COD, total nitrogen and total phosphorus in effluent could meet the first class A standards of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (the ammonia nitrogen reached the secondary standard). At the same time, nutrients such as nitrogen and phosphorus ensured the rapid growth of water spinach in VSFCW. During the experiment, the fresh weight of each Ipomoea aquatica increased by 25.62 g on average, and the average plant growth was 20.6 cm, which has a great potential for resource recovery. |
