摘要
在好氧曝气条件下进行硝化反应时,由于没有厌氧区的形成,也没有外加碱度,这使得在反应过程中pH下降,造成硝化反应的不完全,出水氨氮值变高。通过研究进出水前后pH的变化与氨氮去除效率的相关关系,可以利用pH的变化值预测氨氮的去除效率,及时发现系统中硝化反应的不完全,同时研究反应器内长期呈酸性情况下的污水处理效果。
In the aerobic conditions,the nitrification,due to the formation of anaerobic zone,no inherent alkalinity,makes the reaction process in the pH drop,resulting in incomplete nitrification reaction.The effluent ammonia nitrogen value becomes high.The removal efficiency of ammonia nitrogen can be predicted by using the change of pH value by studying the correlation between pH value changes and ammonia nitrogen removal efficiency before and after the reaction.The nitrification reaction is not complete in the system has been found immediately.At the same time,sewage treatment effect in the case of long-term acidity in the reactor has been studied.
