高含氯采油废水COD_(cr)测定质量控制方法研究

The Study on Quality Assurance Methods of monitoring COD_（cr） of Producing Wastewater with chlorine content

通过对高含氯采油废水CODcr测定过程中因稀释产生的滴定误差和高含氯采油废水现场加标回收率测定结果的分析，提出了适宜高含氯采油废水的质量控制方法，即空白试验值判断法、平行双样法和密码样控制法。

Through assessing titration error due to dilution and the monitored results of reclaim ratio of producing wastewater with chlorine content, the quality assurance methods for producing wastewater with chlorine content is recommended, including that of blank experiment value, parallel double sample and code sample.
