精馏系统优化调整降低含醇水COD技术研究

Optimization of rectification system to reduce COD of alcohol containing water

针对山西焦化股份有限公司甲醇厂精馏系统常压塔所排含醇水中COD偏高的实际情况,通过优化工艺指标调节和检验分析数据,使含醇水中COD明显降低,保障了外排污水达生化处理指标。

According to the actual situation of the high COD in the alcohol water of the distillation system of methanol plant in Shanxi Coking Co.,Ltd.,by optimizing the technological index and checking the analysis data,the COD in the alcohol water is obviously reduced,and the biochemical treatment index of the external sewage water is guaranteed.
