Resourceful treatment method for N-methyl pyrrolidone production wastewater

The invention provides a resourceful treatment method for N-methyl pyrrolidone production wastewater. The resourceful treatment method comprises the following steps: separating methylamine in the wastewater through steam stripping and recycling the methylamine for production; steam stripping water is treated by the SBR reaction unit, the ABR reaction unit and the A/O reaction unit to reduce various organic matters in the wastewater; carrying out flocculent precipitation on biochemical effluent, and carrying out advanced treatment by using an O3/H2O2 advanced oxidation process; deeply oxidized effluent is subjected to UF and RO treatment, and RO fresh water is reused for enterprises; evaporating the concentrated solution to recover a byproduct sodium sulfate; a small amount of mother liquor is dried and then subjected to outsourcing treatment. Methylamine and sodium sulfate substances in the wastewater can be separated and purified, and resource utilization of the wastewater is achieved. 本发明提供了一种N-甲基吡咯烷酮生产废水资源
