In our lives, there are many factors that can cause the indicators in the water to exceed the standard. The internal reflux can cause excessive ammonia nitrogen! What’s going on? This chapter water quality online monitor manufacturers to learn together with you!
In fact, there are two main reasons for the excessive ammonia nitrogen caused by internal reflux: 1. There is an electrical fault in the internal reflux pump (there will be a running signal when the site stops); 2. Mechanical failure (such as: impeller off) and human-caused failure (internal return pump has not tried positive and negative rotation, the site is in reverse state).
Specific analysis: internal reflux leads to excessive ammonia nitrogen can be over-attributed to organic impact, because there is no reflux of nitrification solution, resulting in A small amount of external reflux carried nitrate nitrogen in pool A, the overall anaerobic environment, carbon sources will only be hydrolyzed and acidified, but not all metabolized into carbon dioxide escape. As a result, a large amount of organic matter enters the aeration tank, resulting in the increase of ammonia nitrogen in the water!
How Should We Solve This Problem?
In fact, the problem of internal reflux is easy to be found, and it can be judged whether it is an internal reflux problem by data and trend. In the early stage, the nitrate nitrogen at the outlet of pool O increases, the nitrate nitrogen in pool A decreases to zero, and the PH decreases. There are two specific solutions:
1.Find the problem in time, how the internal reflux has caused the increase of ammonia nitrogen, check the return pump in time, stop or reduce the inlet water to suffocate, check and repair the internal return pump;
2.The nitrification system has collapsed, stop the water implosion, if there are conditions, the situation is more urgent, you can add a similar nitrogen removal system of biochemical sludge, speed up the recovery of the system.
What method is used to find ammonia nitrogen in water? This can be real-time monitoring of sewage through ammonia nitrogen online monitor, from the data can know whether ammonia nitrogen exceeds the standard!
