摘要
在硝基苯类、苯胺类废水处理过程中,污水处理生化系统使用反硝化菌种,可以提高生化系统的反硝化速率,达到提高总氮去除量的目的.结果表明,当生化系统受到高浓总氮污水冲击时,通过投加反硝化菌种以及调整相关工艺,14 d 左右即可将出水总氮由约450 mg/L 降至200 mg/L以下,达到客户的要求.
Abstract
In the process of treating nitrobenzenes and anilines wastewater,the use of denitrifying bacteria in the sewage treatment biochemical system can improve the denitrification rate of the biochemical system and achieve the goal of increasing total nitrogen removal.The results show that when the biochemical system is impacted by high concentration total nitrogen wastewater,by adding denitrifying bacteria and adjusting relevant processes,the total nitrogen in the effluent can be reduced from about 450 mg/L to below 200 mg/L in about 14 days,meeting the customer's requirements.
