Difficult point.Firstly, anaerobic ammonia oxidizing bacteria is Density dependence type Pseudomonas, activity can be just shown when population density is higher.And anaerobism ammonia
Oxidation bacteria multiplication rate is slower, and the period in epoch was up to 11 days；It will appear the more difficult enrichment of Pseudomonas in process operation and activity be lower
The problem of.Secondly, taking place mostly in nitrite oxidizing bacteria there are nitrite substrate competition phenomenon in integral system and detesting
Between anaerobic ammonium oxidation bacterium.Therefore, sludge loss and nitrite oxidizing bacteria increased activity can lead to integrated short distance nitration-and detest
Anaerobic ammonium oxidation technique is difficult to realize.
