应用于近海口水体的氨氮在线分析仪开发

Development of on-line Ammonia-nitrogen Analyzer for Inshore Estuaries Waters

对于近海口的水样,由于盐度、硬度、浊度等因素的影响导致普通的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。本文针对此问题构建一台逐出氨氮在线分析仪完美的解决了近海口水样中氨氮测试的干扰问题,结果表明逐出氨氮分析仪比对误差都在±10%以内,能满足实际使用需求。

For the water samples from the inshore estuary, due to the influence of salinity, hardness, turbidity and other factors, the test data of the ordinary on-line automatic monitoring instrument for ammonia water quality are not accurate, and the passing rate of the comparison is low. Therefore, it is necessary to find a suitable method to improve the pass rate of comparison. In order to solve this problem, a on-line analyzer for ammonia expulsion is constructed in this paper, which solves the interference problem of ammonia test in the water samples from the inshore estuary.
