| 摘 要： | 以程序化方式介绍了判别水质自动监测中测量突变的原因。提出当发现某主要指标异常时，应查看相关指标的运行情况，再校准仪器，并人工同步分析样品。若测定结果的相对偏差大于5％，表明测量仪器故障；若相对偏差小于5％，应继续进行源水分析比对，以判别是仪器故障还是污染事故。通过实例分析，淮南市水质自动监测中DO测量值偏低的原因：一是取水泵安装位置不当，造成负压抽水，使水中DO溢出；二是流程太低，致使管道藻类大量繁殖，消耗了水中DO。解决方法：正确安装取水泵，并加大水泵抽水量，冲刷管道藻类。

| Abstract: | The method to judge the reason of detection result's mutation in water quality's automatic monitoring was studied. When abnormal data were found, it should check the running state, and correct instruments, and analyze samples by hand. If the relative deviation was less 5%, it should comparatively analyze source-water to determine that it was caused by pollution accident or instrument trouble. Case-study was given out. |
