为了深度处理印染废水,将基于硫酸根自由基的高级氧化法与序批式活性污泥法(SBR)相耦合;采用磁性氧化锰八面体分子筛(OMS-2)作为活化过硫酸氢钾(PMS)的催化剂,结果表明:当X-3B初始浓度为50 mg·L-1时,PMS=0.25 g· L-1、磁性OMS-2=0.25 g-L-1,4h之内去除率可达93.66％.磁性OMS-2/PMS的浓度对SBR系统处理效果影响明显,低浓度磁性OMS-2/PMS(低于0.5g·L-1)对SBR系统处理效果具有促进作用,高浓度OMS-2/PMS(大于或等于0.5g·L-1)则会抑制SBR系统处理效果;此外,低浓度磁性OMS-2/PMS能提升SBR系统的缓冲能力.“,”For advanced treatment of dye wastewater,the sulfate radical based advanced oxidation process coupled with the sequencing batch reactor activated sludge process (SBR) was studied.The magnetic manganese oxide octahedral molecular sieve (OMS-2)was prepared as the catalyst for potassium peroxymonosulfate(PMS) activation.The results showed that,when the concentrations of X-3B,PMS and magnetic OMS-2 were 50 mg · L-1,0.25 g· L-1 and 0.25 g· L-1,respectively,the removal of X-3B reached 93.66％ within 4 h.The efficiency of SBR was strongly influenced by the magnetic OMS-2/PMS,which increased at low magnetic OMS-2/PMS concentrations (lower than 0.5 g · L-1),but decreased at high concentrations (equal or greater than 0.5 g · L-1).Besides,the buffer capacity of SBR could be promoted by low concentration of magnetic OMS-2/PMS.
