摘要
文章采用改进A^2O工艺（辅助化学磷回收）进行脱氮除磷和污泥减量的实验研究。实验结果表明，在进水COD质量浓度为150-180mg／L时COD、氨氮和总磷的去除率分别达到90％、97．9％、91．6％，结合化学磷回收后污泥产量减少约为10％～25％，并可进行磷的回收，实现磷的可持续发展，大大提高了污水处理厂的运行效益。
This paper conducts the nitrogen and phosphorus removal and sludge reduction by adopting the improved A^2O process combined with phosphorus recovery by the chemical process. The experimental study demonstrates that the removal efficiency of COD, NH4^ ＋ and TP reached 90%, 97.9%, and 91.6% respectively, the amount of sludge was reduced 10%-25%, and phosphorus was recovered by the chemical process when the mass concentration of COD of the intake is between 150 mg/L and 180 mg/L. The results indicate that sustainable development of phosphorus is achieved by phosphorus recovery, which greatly enhances the operation benefit of wastewater treatment plants.
