区域地表水TOC与COD_(Cr)及COD_(Mn)相关性研究

Research on the Relative Characteristics between TOC,COD_(Cr) and COD_(Mn) on Regional Surface Water

针对本地区地表水有机污染物的特点,采用国家标准方法对区域地表水中的总有机碳(TOC)、化学需氧量(CODCr)和高锰酸盐指数(CODMn)进行监测,对TOC测定值与CODCr和CODMn测定值分别进行线性回归,研究地表水中TOC与CODCr及CODMn的相关性。TOC分析仪测定快捷、高效,可在本区域河流突发性环境事故应急监测时,由TOC测定值快速估算CODCr和CODMn的数值,为应急事故的迅速、准确处置提供技术支撑。

Specially focusing on characteristics of organic pollution of this regional, using national standard method, total TOC, CODcr and CODMn in the surface water was inspected, respectively. CODcr and CODMn linear regression analysis was carried out in terms of TOC measured result. The relative characteristics of TOC, CODcr and CODMo were analyzed Because TOC analyzer was highly efficient and effective in measuring local fiver enviormental accidents and emergencies, CODcr and CODMn number gencies. gauged by TOC analyzer provided faster, and more accurate technical support for emer-
