The degradation of nonylphenol ethoxylates( NPEO),with a concentration of 6. 25 ~ 12. 5 mg·L-1in the simulated ,alkaline, denim ,dyeing wastewater,,was investigated. The results of anaerobic batch experiment showed that the total concentration of NP and short-chain NPEO( NP( 1 ~ 3) EO)was around 500 ~ 900 μg·L-1although the removal efficiency of total NPEO was more than 50%.
