What is the reason for the low COD removal rate in AB process of industrial sewage treatment? Are there any third-party companies in Hubei?

(1) Wastewater with too high pH value will definitely affect the activated sludge.

(2) If (2) the 2)PH value exceeds 10, the inflow time will be less than 4 hours, and the impact will not be too great. After more than 4 hours, the therapeutic effect plummeted. If it lasts for more than 2 days, the activated sludge will basically disintegrate.

(3) If the initial PH value is abnormal in a short time, it can be buffered by increasing the reflux ratio to win the impact resistance time.

(4) If it is to be stable for a long time, it is necessary to add a physical and chemical section to prevent abnormal fluctuation of PH value.

Wuhan Green's environmental protection technology is not bad. You can learn more about it, I hope it will help you.
