Study on Dealing With High Concentrated Ammonia Nitrogen Wastewater by Blow-off Method

Based on the experiment of dealing with high concentrated ammonia nitrogen wastewater by blow-off method, the effect factors such as temperature, pH value, air/liquid volume ratio, initial wastewater concentration are analyzed. The result shows that removal rate of ammonia nitrogen can be above 99.31% in the optimum process conditions. At the same time, the effects of different acid absorption of blow-off gas were compared to find the most suitable acid absorption liquid.
