炼油化工污水中溶解性难生物降解COD的测定研究

摘要

In this paper,based on the evaluation of aerobic biodegradability of organic compounds in aqueous medium,one optimized,simple and operational indirect measurement method is brought to test the recalcitrant COD in wastewater. Using the above method,some petrochemical wastewater was sampled and the recalcitrant COD was analyzed,the result was used for the design reference and basis of the tertiary treatment process.%基于含水介质中有机物生物降解性评定方法，提出了一种优化、简单、易操作的间接测定污水中溶解性难生物降解COD的方法。并对某石化污水中溶解性难生物降解COD进行了测定分析，实验结果为该石化污水深度处理工艺的选择提供了设计依据和基础。
