A treatability study of industrial wastewater containing chlorinated nitroaromatic compounds (CNACs) by a catalytic ozonation process (COP) with a modified Mn/Co ceramic catalyst and an aerobic sequencing batch reactor (SBR) was investigated.A preliminary attempt to treat the diluted wastewater with a single SBR resulted in ineffective removal of the color,ammonia,total organic carbon (TOC) and chemical oxygen demand (COD).Next,COP was applied as a pretreatment in order to obtain a bio-compatible wastewater for SBR treatment in a second step.The effectiveness of the COP pretreatment was assessed by evaluating wastewater biodegradability enhancement (the ratio of biology oxygen demand after 5 d (BOD5) to COD),as well as monitoring the evolution of TOC,carbon oxidation state (COS),average oxidation state (AOS),color,and major pollutant concentrations with reaction time.In the COP,the catalyst preserved its catalytic properties even after 70 reuse cycles,exhibiting good durability and stability.The performance of SBR to treat COP effluent was also examined.At an organic loading rate of 2.0 kg COD/(m3·d),with hydraulic retention time (HRT)=10 h and temperature (30±2) °C,the average removal efficiencies of NH3-N,COD,BOD5,TOC,and color in a coupled COP/SBR process were about 80%,95.8%,93.8%,97.6% and 99.3%,respectively,with average effluent concentrations of 10 mg/L,128 mg/L,27.5 mg/L,25.0 mg/L,and 20 multiples,respectively,which were all consistent with the national standards for secondary discharge of industrial wastewater into a public sewerage system (GB 8978-1996).The results indicated that the coupling of COP with a biological process was proved to be a technically and economically effective method for treating industrial wastewater containing recalcitrant CNACs.  相似文献
