  • 摘要: 采用正交实验对催化剂NiO/γ-Al2O3的制备条件进行优化,并探讨臭氧催化氧化法对于印染废水的深度处理效能。结果表明,最优的催化剂制备条件为:浸渍液浓度为3%、浸渍时间为4h、灼烧温度为450℃、灼烧时间为3h。臭氧催化氧化反应15min时,COD浓度由84.22mg/L降低至50.00mg/L以下;氨氮浓度由10.88mg/L降低至5.01mg/L;色度去除率达到69%,明显高于单纯臭氧氧化的反应效率。
    Abstract: The preparation method of NiO/γ-Al2O3 as catalyst was optimized through orthogonal test and the advanced treatment efficiency of dyeing wastewater through catalytic ozonation process was also discussed. Results showed that the optimal catalyst preparation conditions are: impregnating solution concentration of 3%, immersion time of 4 h, burning temperature of 450℃ and burning time of 3 h. When kept ozone oxidation of 15 min, COD concentration decreased from 84.22 mg/L to 50.00 mg/L, the NH3-N concentration decreased from 10.88 mg/L to 5.01 mg/L, and the chromaticity removal rate reached to 69%, which showed higher reaction efficiency than that of single ozone oxidation process.
