Breeding is played an important role in socio-econimic development. However, the development of piggery production has caused serious environmental pollution. At the present, after treatment, piggery farm wasterwater still has not met the Vietnam National Wastewater Standards. This study was aimed to evaluate Swine farm wastewater treatment post biogas using the floating platform technique with Pennisenon purpurecums - Schumach combined Biochar, flow rate: 10l per day and retention time: 6 days. The result showed that COD, TN, TP, PO43-, NH4+, NO3-treatment efficiencies are 53,59%, 62,46%, 29,69%, 33,57%, 61,51%, 33,41%, respectively. Waste water after treatment meets criteria B column QCVN 62-MT: 2016 / BTNMT on COD, TN.
