摘　　要：大量含氮含磷工业废水排入水体,造成水体富营养化,水质恶化,威胁生态系统稳定性。因此总氮总磷含量的测定具有重要的现实意义,其测量的准确与否,直接影响到排放监测数据的可靠性、工业废水的处理能力和控制指标实施效果。本文通过紫外分光光度法对工业废水中总磷总氮联合测定方法进行验证,使其过程便捷快速高效,其结果具有可行性和准确性。A large amount of industrial wastewater containing nitrogen and phosphorus is discharged into water,resulting in eutrophication of the water body,deteriorate the water quality and threat the ecosystem stability.Therefore,the determination of total nitrogen and total phosphorus content has important practical significance.The accuracy of the measurement directly affects the reliability of emission monitoring data and the treatment capacity of industrial wastewater and the implementation effect of control indicators.In this paper,the combined determination of total phosphorus and total nitrogen in industrial wastewater by ultraviolet spectrophotometry was validated to make the process convenient,fast and efficient,and the results are feasible and accurate.
