DO对CAST工艺中主要污染物去除的影响

Impact of DO on the Removal of Major Pollutants in CAST Process

主要介绍了CAST工艺的特点,DO对CAST池主要污染物去除的影响。提高CAST池内DO浓度有利于COD和氨氮的去除,但过高的DO不利于脱氮除磷。选择恰当的DO浓度,既节能,又提高了污水处理效果。

Introduces the characteristics of the CAST process, and the impact of DO on the ：removal of major pollutants in CAST pool. Improving the DO concentration in CAST pool favors the ＇removal of COD and ammonia nitrogen, but DO with much too high concentration is not conducive to remove nitrogen and phosphorus. Select the appropriate concentration of DO not only can save energy, but also can improve the sewage treatment effect.
