| 摘 要： | 用Fe-C-H2O2协同催化氧化体系对印染工业废水的降解脱色处理进行了研究。对影响印染废水降解的几种因素如铁屑/碳粒质量比、双氧水的质量分数、废水pH等进行考察。试验结果表明,对于色度为650度和ρ（COD）为468mg·L-1的印染废水,在废水pH=4.8的情况下,当铁屑/碳粒质量比为25∶1、H2O2用量为150mg·L-1、催化反应30min时,印染废水的脱色率达98%以上,CODCr去除率可达78%。与Fe-C微电解法相比,Fe-C-H2O2协同催化氧化方法对印染废水的脱色能力和去除COD,表现出了更好的处理效果。

| Abstract: | The treatment of dye wastewater with a new catalytic reactive system of Fe/C/H2O2 was studied. The effects of the Fe/C mass ratio, the concentration of hydrogen peroxide, the pH of wastewater, and the system temperature on the deodorization and the COD removal of wastewater were researched. The experimental results shown that, under the conditions of room-temperature, the deodorization ratio and removal ratio of CODCr were 98% and 78% respectively when the mass ratio of Fe/C is 25：1, pH=4.8, the concentration of hydrogen peroxide is 150 mg·L-1, and the reaction time is 30 min as the colourity and CODCr of the wastewater is 650 and 468 mg·L-1 respectively. Compared with the system Fe/C micro-electrolysis, the treatment efficiency of dye wastewater by the new reaction system of Fe/C/H2O2 is higher. |
