| 摘 要： | 化学需氧量（CODCr）与总有机碳（TOC）指标均可用来表征废水的有机物污染程度.不过，以CODCr表征有机物污染程度一般只能反映水中部分有机物的量，而TOC能更全面地反映废水中有机物的含量.以丙烯酸生产外排废水为研究对象，分析结果表明：在一定范围内，废水中CODCr与TOC满足关系式y=1.147 4x+74.75（R2=0.955 26），回收率范围98%~115%，TOC测定结果的精密度高、可靠、准确，在一定条件下，可使用TOC来间接换算CODCr.

| Abstract: | Both chemical oxygen demand(CODCr) and total organic carbon(TOC) can be used to characterize the organic contaminant level. CODCr index, generally can only reflect a part of the content of organic compound in the evaluation of polluted wastewater, while TOC can comprehensively reflect the contents of organic compounds in wastewater. The acrylic wastewater was analyzed, the results showed that these two indicators met the relationship y=1.147 5x+74.75(R2=0.955 26). The recovery ranges were from 98%~115%, the TOC determination data were accurate, reliable and of high precision under certain conditions. TOC can be converted into CODCr indirectly. |
