摘要
研究了炼油废水生化出水的CODCr和CODMn的相关性,获得了CODCr与CODMn的一元线性回归方程。利用二者的线性关系,对轻度污染的废水和特征污染物相对稳定的水体,采用CODMn测定,既缩短了分析周期、减少二次污染、降低分析成本,又能保证分析结果的准确性,具有较强的实用性。
The relativity of chemical oxygen demand （CODer） and permanganate index（COil）of biochemical treated refinery effluent was studied, and their equation of linear regression was gained. By utilizing of the linear relationship between them, both the light pollution wastewater and the characteristics of a relatively stable body of water pollutants were determined by the method of CODMn. It not only reduced cycle time and secondary pollution, decreased the cost of analysis, but also ensured the accuracy of analysis results with a strong practicability.
