The COD level of the incoming water is over 9,000; after passing through the anaerobic tank, it drops to around 400, and after the aerobic treatment process, it remains at over 200. How can this value be reduced to 100? We don’t have any equipment for secondary wastewater treatment – please give me some suggestions, thank you! Settling ratio 26
The sludge concentration is low. Add more activated sludge and see
When COD is at this level, it becomes very difficult to further reduce it, and the treatment costs will inevitably remain high. Therefore, it is more cost-effective to choose a method that requires moderate investment and low operating costs. I have seen industrial cases in the coal chemical industry where COD was reduced from 200–300 to below 60, with moderate treatment costs and investment. If you’re interested, please leave your contact information so we can discuss this further and learn from each other*
