摘要：In previous studies, an integrated process (flocculation, struvite precipitation, Chlorella vulgaris and bacteria co-treatment) was shown to be a potentially effective treatment for anaerobically digested swine manure (ADSM). In this study, the biological treatment ( Chlorella vulgaris and bacteria) of this integrated process was scaled up to improve the operating conditions and implemented in an open vertical runway treatment system. With continuous analysis and improvement of natural conditions, equipment and environmental factors, the effect of biomass accumulation, and pollutant removal of the system, were significantly improved. After 7 days of treatment, the biomass accumulation in the system reached 2.06±0.11 g/L, and the removal rates of COD, NH 4+ -N, TN and TP reached 75.7%, 99.3%, 79.7% and 76.9%, respectively, in the second 100 L batch. Gradual scaling-up process could optimize operating conditions and improve system performance, and this integrated treatment process will become practical in treating ADSM. ? 2022, The Authors.
