含四氢呋喃化工废水处理工程实例

Engineering Example of Treatment of Chemical Wastewater Containing Tetrahydrofuran

采用"预处理芬顿反应池—UASB池—兼氧池—好氧池—二沉池"工艺处理四氢呋喃废水。考虑了废水处理的影响因素。运行结果表明:此工艺能够有效去除含四氢呋喃废水;废水处理系统进水COD:15000 mg/L,系统出水COD:142 mg/L,COD去除率为99%,排放指标低于企业要求的接管标准。

Tetrahydrofuran wastewater was treated by pretreatment Fenton reaction tank UASB facultative aerobic tank secondary sedimentation tank. The influence factors of wastewater treatment are considered. The running results show that: his process can effectively remove the wastewater containing tetrahydrofuran;Influent of wastewater treatment system COD:15000 mg/L, COD of system effluent: 142 mg/L, The COD removal rate is 99 %, The emission index is lower than the takeover standard required by the enterprise.
