Ammonia nitrogen degradation bacteria for industrial wastewater treatment

What is the reason why ammonia nitrogen in waste water does not fall but rise?  The main points are as follows:  

1. The organic nitrogen in the wastewater generates a large amount of ammonia nitrogen through ammonification, which leads to the situation that the ammonia nitrogen of the wastewater after the biochemical pond does not decrease but increases.  

2. The concentration of nitrifying bacteria in the wastewater is too low, and the ammonia nitrogen index into the biochemical pool is high, resulting in the limited function of the aerobic pool for nitrification reaction, and the ammonia nitrogen index can not be reduced in the sedimentation pool.  

3. The wastewater entering the aerobic pool contains harmful substances or inert substances, which inhibits the growth of the original nitrifying bacteria and microorganisms in the pool, leading to the unsatisfactory nitrification reaction effect.  

4. The PH value in the aerobic pool is too high or too low. Generally, the PH value of the aerobic pool is better between 7-9. The whole nitrification reaction needs to be carried out in an alkaline environment.  

5. The growth of microorganisms in sewage also has strict requirements on the environment. The temperature of nitrifying bacteria is between 10-40 degrees, and the temperature of 25-30 is better for the rapid propagation of nitrifying bacteria.  If the temperature in the water is too low, the active enzymes of the bacteria in the water will be reduced, so the activity of the bacteria will be low, and the processing capacity will be reduced.  

6, the influence of dissolved oxygen in the aerobic pool, the dissolved oxygen in the aerobic pool is the value of 2-4mg/L, if it is too low, there will be an anaerobic aerobic pool, not nitrification, denitrification is carried out.  The ammonia nitrogen in the water will not fall down.
