混凝/水解/两级缺氧好氧工艺处理异丙胺废水

Coagulation and Sedimentation/Hydrolysis-acidification/Two-stage Anoxicaerobic Process for Treatment of Synthetic Isopropylamine Wastewater

采用混凝沉淀／水解酸化／两级缺氧好氧工艺处理异丙胺合成废水，处理规模为500m^3／d。实际运行结果表明，在实际进水COD为1500～2800mg／L、TKN为80～180mg／L的情况下，对COD的去除率能够稳定在96％以上，出水NH4^＋-N稳定在11mg／L以下，出水控制指标均能达到《污水综合排放标准》（GB8978-1996）的一级标准。

The combined process of Coagulation-sedimentation, hydrolysis-acidification and two- stage anoxic-aerobic treatment is used to treat synthetic isopropylamine wastewater, and the treatment capacity is 500 m^3/d. The practical operation shows that when the influent COD and TKN are 1 500 to 2 800 mg/L and 80 to 180 mg/L respectively, the removal efficiency of COD is more than 96% , and the effluent NH4＋ -N is less than 11 mg/L. The effluent quality meets the first class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）.
