Biological treatment method for dimethylformamide wastewater

The invention discloses a biological treatment method for dimethyl formamide (DMF) wastewater, and belongs to the field of biological treatment of high-concentration DMF wastewater. According to the treatment method, wastewater is sequentially subjected to activation and culture of DMF exclusive solid strains and wastewater treatment, the process is easy to operate and efficient in reaction, DMF can be degraded and finally oxidized into NH3 and CO2, and DMF is degraded. The wastewater with the inlet DMF concentration of 10000 mg/L or below can be treated, professional biodegradation can be carried out, and the DMF degradation efficiency is higher than 99.5%. According to the method, a common biological method is upgraded and enhanced, and the application range of biological treatment of the DMF wastewater is widened. 本发明公开了一种二甲基甲酰胺废水生物处理方法，属于生物方法处理高浓度二甲基甲酰胺（DMF）废水领域。所述的处理方法中废水依次经过DMF专属固体菌种激活及培养→废水处理，该工艺操作简单、反应高效，可将DMF降解，最终氧化为NH3和CO2，DMF得到降解。可处理进水DMF浓度10000mg/L以下废水，能够进行专业生物降解，DMF降解效率高于99.5%。本发明的方法是对普通生物法的升级加强，
