N-methyl-2-pyrrolidone (NMP) was selected as the sole carbon and nitrogen source, and a strain NCSL-HH10 that could efficiently degrade NMP was isolated from the cleaning wastewater of lithium-ion battery cathode slurry mixer. 16S rDNA sequencing and phylogenetic affiliation analysis showed that this strain belonged to Burkholderia contaminans. The results showed that 100% NMP removal and 94.3% TOC removal could be obtained in 1500mg/L NMP wastewater within 48h using this strain. Such a high mineralization degree indicated that the strain possessed a relatively complete NMP degradation pathway. In addition, the strain could completely degrade NMP with a concentration as high as 15000mg/L, which displayed the highest NMP degradation concentration with a high mineralization degree (63.2%) compared to the publicly available literatures. Finally, 10000mg/L NMP wastewater was treated by Burkholderia contaminans NCSL-HH10 and activated sludge under open environment, respectively. It was found that 95.7% NMP and 76.5% TOC were removed within 60h by NCSL-HH10, which was significantly higher than activated sludge (only 39.0% NMP and 30.2% TOC were removed within 84h).
