磁性OMS-2/SBR耦合处理活性染料X-3B废水
Advanced treatment of simulated X-3B wastewater by coupling magnetic OMS-2 with SBR
摘要
Abstract
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.关键词
