摘要
污水回用中氨氮去除有许多方法。当经处理的城市污水回用于工业循环冷却水系统时 ,利用冷却塔的曝气作用 ,控制pH7.0~8.0,污水含氨氮20~50mg/L,浓缩倍数为2的条件下 ,可使循环水的氨氮浓度<1mg/L。
There are many ways for the removal of NH3_N in the reusing wastwater.When treated municipal wastewater is reused for industrial circulating cooling water system,it is possible to make NH3_N concentration in the circulating water < 1 mg/L by using the aerating function of cooling tower to control the pH value between 7.0 and 8.0, the NH3_N concentration in the wastewater at 20~50 mg/L and the concentration times at 2.
