摘要
分析了引起含油废水CODCr测值偏低的原因主要为取样误差 ,并通过实验验证其影响是巨大的。提出了通过加入表面活性剂AEO -9改善废水均值程度 ,提高分析结果准确性的解决办法。
The reason of lower COD Cr value lies in sampling error and the impact is obvious through experiment test.The solving ways are pointed out by adding surface activity agent Aeo-9,and also more accurant analytical rusult will be gained.
