Abstract
There are many deficiencies of COD index in evaluation of organic pollution wastewater,while TOC can better reflect the content of organic compounds in wastewater. The high-salinity organic chemical wastewater was pretreated by the process of multi-stage adsorption with activated carbon,and the correlation between COD and TOC in wastewater,adsorption effluent and regeneration fluid was analyzed. The results showed that:COD and TOC met the relationship COD=56.537 7+0.967 04TOC;During the process of adsorption,COD and TOC were still linearly related,but independent regression equations should be established for different stages;The precision of TOC determination was better than that of COD,and the recoveries ranges from 98.59% to 110.69%;According to the linear regression equations,TOC determination data could be used for COD prediction with accurate,reliable and good-precision results.关键词
