用微电解-Fenton试剂催化氧化组合工艺对Fischer-Tropsch合成废水进行预处理,研究探讨该处理过程中各种反应条件和工艺参数对处理效果的影响.结果表明:在微电解铁炭体积比1:1 ,进水pH为3.0,反应时间120 min的条件下,对F-T合成废水中COD_(Cr)的去除率达到39.2%;微电解后出水经Fenton试剂进一步氧化,在pH为3,H_2O_2的投加量为 30 mL/L,反应时间为 90 min时,其COD_(Cr)的去除率可达69.4%.ρ(BOD_5)/ρ(COD_(Cr))可从0.06提高到0.32,有效地提高了废水的可生化性.

The waste water from Fischer-Tropsch synthesis was pretreated through the combined method of Microelectrolysis-Fenton reagent catalytic oxidation. Then the effects of various reaction conditions and process parameters on treatment efficiency were investigated. The results suggest that: the COD_(Cr) removal rate reached 39. 2% when iron and charcoal volume ratio in mi-croelectrolysis was 1:1, pH of influent was 3.0 and reaction time was 120min; the effluent after micoelectrolysis was further oxidized by Fenton, the removal rate of COD_(Cr) could reach approximately 69.4% when pH, dosing quantity of H_2O_2 and reaction time was 3.0, 30 mL/L and 90 min, respectively. The BOD_5/COD_(Cr) value was improved from 0.06 to 0.32, and the biodegrad-ability also got improved effectively.
