摘　　要：对于有浊度的现场地表水水样,氨氮水质在线自动监测仪测试数据不准,比对合格率较低,因此,需要寻找合适方法提高比对合格率。针对在线仪器进行算法补偿,结果表明经过算法升级后的监测仪比对误差都在±10%以内,能满足实际使用需求,同时由于在线仪器只需升级算法就可实现自动补偿,无需对仪器进行改造,不增加任何成本,且进行算法补偿后基本不会延长测试时间。when using the water quality automatic monitoring instrument of ammonia monitor the content of ammonia in the surface water with turbidity,the result was inaccurate and the qualified rate of comparison was low.Therefore,it is necessary to research appropriate method to improve higher qualified rate of comparison.In this paper,algorithm compensation was carried out for online instruments.The result shows that the comparison error of monitors after algorithm upgrade is within±20%,which can meet the actual using requirements.At the same time,because the online instruments can realize automatic compensation by upgrading the algorithm,so there is no need to transform the online instruments,and no additional cost The algorithm compensation basically does not extend the testing time.
