使用催化 曝气微电解 工艺对石 油炼厂延 迟焦 化装 置高 浓度 生产 废水 处理 进行 了现 场 小试研究。 重点考察 了微电 解的作用 和 影响 因素 ，并 结合 电 导率、氧化 还 原电 位（ Ｏ Ｒ Ｐ） 的变 化 特 点对处理机 理进行了 探讨，为 中试设计 及运行 提供了较 为完整 的参数。 结果表 明：对 Ｓ２ － 及 Ｃ Ｏ Ｄ Ｃｒ 总去除率分 别可达 ９０ ％ 和６８ ％ 以上，并 大幅提 高了可生 化性，该 工艺 对炼 厂高 浓度 废水 具有 良好 处理效果
The catalytic aeration-micro-electrolysis process was used to conduct a small-scale pilot study on the treatment of high-concentration wastewater from delayed coking units in petroleum refineries. The effects and influencing factors of micro-electrolysis were investigated emphatically. Combining with the characteristics of conductivity and redox potential (O R P), the treatment mechanism was discussed, which provided more complete parameters for pilot plant design and operation. The results showed that the total removal rates of S2 - and C O D Cr were up to 90% and 68%, respectively, and the biodegradability was greatly improved. The process has a good treatment effect on high concentration wastewater from refinery
