What is the reason for the excessive ammonia nitrogen in the sewage plant？

Reason

1. The ammonia nitrogen concentration in the raw water exceeds the process design value

2. The more common temperature, nutrient ratio, pH value, etc. will affect the reproduction of bacteria

3. The factory-related sewage treatment equipment is aging, and the facility maintenance needs to be updated

4. Insufficient residence time for sewage reaction

Solution

1. Control the time that the sewage stays in the biochemical tank

2. Regularly update the activity of sludge and remove inactivated sludge

3. Large enough equipment scale and sufficient load capacity

4. The aeration system must have sufficient aeration volume

5. Control the corresponding nutrient ratio, pH value, temperature, etc.
