Our factory uses the Carrousel oxidation ditch process. Sometimes the ammonia nitrogen level in the water exiting the device is even higher than that in the incoming water; the TP level in the incoming water is around 2.5 mg/L, while it is only about 0.2 mg/L in the outgoing water, with 3 aeration units operating at full capacity. No cause could be found; what’s going on?
What changes have occurred in total nitrogen? What is the specific operating situation like?
Recommended answer: It may be that the wastewater contains a high amount of nitrogen-containing organic compounds, the reaction time is insufficient, and the ammonification rate of organic nitrogen is higher than the nitrification rate of ammonia nitrogen. Additionally, there might not be enough phosphorus, which affects the efficiency of removing ammonia nitrogen through assimilation processes
