城市二级处理后污水直接用作工业循环冷却水的阻垢研究

Scaling resistance study of city secondary treated sewage directly used for industrial circulating cooling water

讨论了采用碳酸盐沉积法及动态模拟试验对城市污水处理厂二级出水直接用作工业循环冷却水时,污水中的悬浮物、COD、浓缩倍率等因素对系统的结垢和药剂阻垢效率的影响。

Adopting the carbonate deposition method and the dynamic simulation test, the effect of factors such as the suspension matter, COD and concentration rate in the sewage on the scaling and the scaling resisting efficiency of the chemicals while directly using the city secondary treated sewage for the industrial circulating cooling water was discussed.
