The invention belongs to the technical field of unsymmetrical dimethylhydrazine waste gas treatment, and particularly relates to an unsymmetrical dimethylhydrazine production tail gas solid waste treatment method which comprises the following steps: S1, arranging a purification system and a monitoring instrument on a waste gas discharge pipeline; and S2, monitoring the content and concentration of waste gas and unsymmetrical dimethylhydrazine generated during unsymmetrical dimethylhydrazine production. S3, carrying out separation and filtration treatment on the waste gas by adopting a membrane separation technology according to the monitoring data; and S4, carrying out secondary monitoring on the waste gas and unsymmetrical dimethylhydrazine separated and filtered in the S3, and judging whether adsorption purification is completed or not. According to the invention, the unsymmetrical dimethylhydrazine and the waste gas generated by the unsymmetrical dimethylhydrazine can be effectively purified by utilizing a dual purification mode of combining a membrane separation technology with an activated carbon adsorption method.
