pH对渐变流曝气生物滤池处理城市污水的影响

摘要

考察自制渐变流曝气生物滤池中pH对其处理城市污水中的化学需氧量、氨氮、总磷的影响效果。pH为5～9时，中性环境下对三种污染物的去除率最高，强碱或强酸都不利于去除这三种污染物。%The influence of pH on the self-producing gradient flow BAF in treating CODCr,NH3-N,TP in urban wastewater was investigated.When the pH is 5 ~9,the neutral environment is the best for the three pollutant removal,acid or alkali is not conducive to remove these three pollutants.
