Operational issues with the catalytic cracking flue gas desulfurization system?

Desulfurization using catalytic cracking smoke dewetting is a method that, although simple with few steps involved, is not easy to operate effectively. Fellow sailors, please share any difficulties you’ve encountered with smoke dewetting! ! !
We are unable to reduce the COD level of our saline wastewater; it remains around 400.
Is it the dehydrator that’s not working, or is it the bulging filter?
Do you use liquid ammonia or injections?
It’s been installed; we have three tanks connected in series. Previously, we used main air supply, but the COD level wouldn’t drop. Later, we switched to rotary blowers, yet the COD level still didn’t decrease.

We have no problems; no visible surface issues, it’s just that the COD level doesn’t go down. The design institute also came to take a look and couldn’t find any problems; in the end, the only conclusion they could reach was that it was overloaded.
