Technical question: By how much can COD be reduced?

This post was last edited by hesonchang214 on 2011-6-18 at 16:42. For ammonia stripping using a single-tower side stream, the COD of the inlet water is 6000 mg/L. So to what level can the COD of the treated wastewater generally be reduced? Please give me some advice, fellow sailors!
It works fine within 1500, and it’s very stable.
Could you please explain this from the aspects of operation and process flow? At our company, the pressure at the top of the tower is around 0.35 MPa; due to this low pressure, the temperature at the bottom of the tower also doesn’t rise. Additionally, the instrument shows that the amount of ammonia gas being produced is 50 cubic meters per hour.
Reply to 3# daiqijun0000: Please introduce the parameters for incoming water and those for purified water
For the influent water, we only test for COD; we haven’t carried out tests for other parameters yet! As for the effluent water, the test results are as follows: SS: 200, sulfides: 50, volatile phenols: 30, petroleum substances: 50. All values are in mg/l
DDDDDDDDDDDD
It specifically depends on the components that generate COD, namely light and heavy components
