Detailed Product Description
Anaerobic Biological System
Biological nitrogen removal is the application of nitrification and denitrification. Nitrification is a reaction in which ammonia nitrogen is oxidized to nitrite and nitrate by aerobic bacteria under aerobic conditions. Denitrification is the use of NO2-N and NO3-N produced by the digestive reaction in the absence of oxygen to replace the oxygen for the oxidative decomposition of organic matter, and the reduction of N in NO2-N and NO3-N to nitrogen evolution. Complete the denitrification task.
There are many methods for biological nitrogen removal in China, but the application of wastewater is the most economical and effective A/O internal circulation process, such as grid well + oil separation + flotation air flotation + reaction precipitation + ammonia nitrogen stripping + UASB anaerobic reactor + Level 1 A/O biochemical treatment + secondary A/O biochemical treatment + MBR.
