摘要: ABSTRACTThe aim of the study is to assess efficiency a novel bioremediation system namely baffled duckweed pond (BDWP) for treatment agricultural drainage water containing pharmaceuticals at different hydraulic retention times (HRTs). The removal efficiencies acetaminophen (ACT), amoxicillin (AMX), and ampicillin (AMP) increased from 69.3 ± 8.6 87.3 3.5%, 52.9 9.4 82.9 5.2%, 55.3 7.9 90.6 2.8% increasing HRT 6 8 days, respectively. However, ACT, AMX, AMP were slightly improved 8 12 days. Diclofenac (DFC) amounted 56.6 11.6, 55.7 11.9, 28.3 12.9% an HRTs 12, 8, 6 days, results showed no relationship between uptake/absorption fractions BOD5/chemical oxygen demand (COD) ratio except ACT where R2 was 0.84. effect COD/N on slight....
