Piggery wastewater includes a lot of hardly degradable pollutants, which are not well removed during treatment plants. In our study, a multi-stage wastewater treatment system was introduced, which contains liquid-solid separation, anaerobic fermentation, aerobic treatment, functional material filtration and oxidation processes. In RPAFR, the readily biodegradable organic matter was degraded, and the removal efficiency of COD and BOD5reached 80%; but nitrogen and phosphorus could not be removed effectively. When MEOD and MFMI were operated to treat digested effluent, nitrogen and phosphorus were effectively removed. The removal of three kinds of antibiotics (FQs, SMs and TCs) in piggery wastewater treatment plants were detected, and for most antibiotics, more than 90% compounds were eliminated, but only few of them were totally removed in wastewater of final effluent. The weather also influenced the removal efficiency of DC, CIP and SMZ, which were better in autumn than spring, however, the whole trend of antibiotics elimination were similar in different weather. Different kinds of antibiotics residues in final effluent enhanced the ecological risk of environmental waters and human health.
