摘要：N，N一二甲基甲酰胺(DMF)是合成革生產(chǎn)中一種常用有機溶劑，但DMF具有一定的毒性，難生物降解。綜述了回收及處理合成革廠廢水中DMF的方法，包括蒸餾、吸附、萃取、生物降解、堿性水解等，分析了各種方法的優(yōu)缺點。針對目前合成革生產(chǎn)企業(yè)配料間廢樹脂料桶的無序管理和污染物的無組織排放，通過對污染物排放量的分析，對廢樹脂料桶的環(huán)境管理及DMF回收作了一些探索性的工作。認為通過科學有效的管理，可對樹脂料桶的DMF和樹脂皮進行有效回收處理，分析了回收帶來的經(jīng)濟效益。并展望了合成革廠DMF廢水回收及處理工業(yè)化應用的研究方向。

Recovery and disposal Synthetic Leather Plant residue of DMF
 
Abstract:N, N 12 dimethylformamide (DMF) is a commonly used synthetic leather production of organic solvents, but the DMF has some toxicity, biodegradable. Summary of the recovery and processing of synthetic leather factory in the DMF method of waste water, including distillation, adsorption, extraction, biodegradation, alkaline hydrolysis.And so, of the advantages and disadvantages of each method. Synthetic leather manufacturers for ingredients now spent resin bucket of disorder between the management and disorganized discharge of pollutants, through the analysis of emissions, waste resin bucket on environmental management and recycling DMF made some exploratory work. That through scientific and effective management, can the DMF and the resin resin barrel is effectively recycled paper analyzes the economic benefits of recycling. And the prospect of synthetic leather factory DMF wastewater recycling and treatment of industrial application of research.
