In order to efficient treatment swine wastewater of chemical oxygen demand(COD) of high concentration, ammonium nitrogen (NH4+-N) of high concentration and high suspended solids (SS) , Up-flow Anaerobic Sludge Bed (UASB) were fed with piggery wastewater and investigated removal effect of COD, SS, NH4+-N, TP. The results showed that, UASB can effectively remove COD and SS in the pig farm wastewater. The corresponding removal rate was respectively 82.36% and 70%. UASB was poor on removal effect of NH4+-N and total phosphate (TP), due to the lack of anaerobic, anoxic environment. UASB is able to treatment COD and SS of piggery wastewater, but TN and TP removal efficiency need to further study.
