摘要：

Iron-carbon filler is added to the short-cut nitrification and denitrification biological reactor (A/O/A) to evaluate the pollutant removal effect. The results show that under the condition of pH=7.8-8.7 and DO=3-5mg/L in oxic unit, the nitrite could be accumulated quickly and the rate of accumulation could reach more than 45%. Meantime, the average removal rate of NH4(+)-N, COD, TP could reach 92%, 88.6% and 90.5% respectively under steady working condition. By comparison, without adding iron-carbon filler, the average removal rate of NH4(+)-N, COD, TP are 86.3%, 79.5% and 80.1% respectively. This technology indicates new directions for urban wastewater nitrogen and phosphorus removal process.
