| 英文摘要 | Arthrospira platensisis a candidate for removing nitrogen from caprolactam wastewater, but the concentrated cyclohexanone (CHN) and cyclohexanol (CHL) in the wastewater have an unknown effect onA. platensisgrowth. The aim of this study was to evaluate the feasibility ofA. platensisfor caprolactam wastewater treatment and obtain safe exposure concentrations of CHN and CHL. The biotransformation of CHN and CHL was investigated. Considering the changes of growth rate and pigment contents, the safe exposure concentrations of individual CHN and CHL were <= 800 and <= 400 mg L-1, respectively. For binary mixture, the safe exposure concentration was <= 200 + 100 mg L-1CHN + CHL. Both chemicals induced decreased trichome length at all concentrations, but trichomes were large enough to be harvested efficiently by gravity filtration using filter membranes with a pore size of 25-40 mu m under safe exposure. The nitrogen removal rate showed no difference in CHN and CHL treatment under safe exposure concentrations compared with the control, and the maximal nitrogen removal rate was 18.66 mg L-1 d(-1). Besides,A. platensiscatalyzed interconversion between CHN and CHL which preferred to convert CHN into CHL when chemicals coexisted. Results highlight the potential ofA. platensisfor the nitrogen removal from caprolactam wastewater when CHN and CHL were under the safe exposure concentrations. |
