A/O生物转盘工艺处理氨氮废水

Treatment of Ammonia Nitrogen Wastewaterwith A/O system and Lasting RotatingBiological Contactor Process

研究了A/O系统后接生物转盘工艺,对低CODCr和高氨氮的石化厂废水的处理效果。结果表明,当碳氮比为3.8时,对 CODCr和氨氮均有良好的去除效果,在进水CODCr浓度为1048.70mg/L,氨氮浓度为275.16mg/L时,COD。去除率达93.26％,氨氮去 除率达94.7％。

The removal effect of low concentrated CODCr and high concentrated ammonia nitrogen wastewater has been studied through experiments with A/O system and Lasting Rotating Biological Contactor (RBC). The result showed that this method has a good ability to remove CODCr and NH3-N, while the ratio of C/N reached 3.8. when the concentration of CODCr in the influent was 1048.70mg/1, and of NH3-N was 275.16mg/l, the removal rate of CODCr was 93.26 %, and of NH3-N could reach 94.73%.
