【Abstract】 The wastewater of hexanolactam (nylon) fiber production in Shijiazhuang Synthetic Fiber manufactory is high concentrated with organic nitrogen compounds. Through theoretic analysis on the problems arisen from the exiting A/O/A/O process and on the basis of experimental research, an alternative program of ENSBR/BDAR/COR process to replace the former has been proposed. The experimental results show that the new process is high effective and stable in operation, also the effluent could be meet the wastewater discharge standard. The reconstruction has been accomplished.更多还原
