摘　　要：介绍了针对外排氨氮标准不断提升,炼油含盐废水处理装置出水氨氮控制难度增加,在一段时期常出现波动情况,投加硝化菌进行生物增效处理达标的生产试验。对试验过程和试验前后含盐污水处理装置进、出水数据进行分析,对照出水pH值与硝化系统的关系,找到了出水氨氮异常升高主要是污水处理系统碱度降低引起的根本原因。证明了投加硝化菌进行生物增效的方法可作为恢复污水生化系统快速建立硝化系统,恢复氨氮去除能力的有效应急手段。With the continuous upgrading of criteria for effluent ammonia nitrogen,it is more difficult to control ammonia nitrogen in the effluent of refinery saline wastewater treatment unit,and fluctuation often occurs during a period of time.This paper introduced the production test of adding nitrifying bacteria to achieve the standard of biological synergistic treatment.Based on the analysis of the data of the inlet and outlet water of the saline wastewater treatment system during the test,before and after the test,the paper compared the relationship between the pH of the outlet water and the nitrification system.It found out that the abnormal increase of the effluent ammonia nitrogen was mainly caused by the decrease of the alkalinity of the wastewater treatment system.It was proved that the method of adding nitrifying bacteria for biological synergism can be used as an effective emergency measure to restore the biochemical system of wastewater,establish the nitrifying system quickly and restore the ammonia nitrogen removal capacity.
