چکیده انگلیسی
Laboratorial scale experiments were conducted in order to investigate a novel system integrating microwave catalytic oxidation (MCO) and MBBR process on advanced treatment of biologically pretreated Lurgi coal gasification wastewater. Results indicated that MCO with catalyst of MOs/SAC (sewage sludge based activated carbon which loaded Mn oxides) represented high efficiencies in eliminating bio-refractory compounds by generating OHâ, O2- and holes. GC-MS analysis indicated the MCO eliminated most bio-refractory compounds and improved the BOD5/COD from 0.08 to 0.48. Meanwhile, the integrated process exhibited efficient performance of COD, BOD5, TOC, NH4+-N and TN removals at a much shorter retention time of 8Â h, with the effluent concentrations of 18.4, 2.3, 10.1, 3.2 and 10.6Â mg/L, respectively, which all met class-I criteria of the Integrated Wastewater Discharge Standard. The total operating cost was 1.6 CNY/t. The integrated system was efficient, cost-effective and ecological sustainable and could be a promising technology for engineering applications.
