摘要：
结合稠油污水处理试验工艺对COD构成进行了分析,将CCl4萃余物视为表观化学药剂,提出稠油污水COD主要由石油类和表观化学药剂二者构成,后者主要包括石油中可溶于水的有机物和油田开发添加的各种可溶性有机物。采用水解酸化-接触氧化工艺的COD去除结果表明,表观化学药剂虽具有一定的生物降解性,但其贡献的COD比例随流程而逐渐增大。生化处理后,低成本的COD去除技术应是关注的重点。

Abstract:
Combined with the treatment experiments of thick oil-bearing wastewater,COD composition has been analyzed,and CCL4 extraction residues are regarded as apparent chemical agents.It is brought forward that the COD of thick oil-bearing wastewater mainly consists of oils and apparent chemical agents.The apparent chemical agents mainly consist of water soluble organics in petroleum and various kinds of soluble organics which was added in oilfield development.The COD removing results obtained by hydrolysis acidification-contact oxidation process show that although the apparent chemical agents have certain biodegradability,the contributed COD ratio increases gradually with the process.After the degradation,close attention should be paid to low cost COD removing technology.
