摘要
采用凝胶法制备负载TiO_2改性粉煤灰,将其作为光催化剂投加到实验室卫生填埋场模型产生的垃圾渗滤液中,在紫外光源照射下,分析探讨了负载条件、渗滤液体系pH、光照时间、负载TiO_2改性粉煤灰投加量对渗滤液中污染物去除效率的影响.结果表明:在温度范围20℃~30℃、光照120min、pH=2、500℃焙烧的负载TiO_2的2mol/L盐酸改性粉煤灰光催化剂的投加量为30g/L时,渗滤液体系中污染物的去除率较高.
The sol-gel preparation of supported TiO2 modified fly ash,the as a photocatalyst,investment and added to the laboratory of sanitary landfill garbage generated by the model infiltration filtrate, under the irradiation of UV light and analysis study load conditions, the leachate pH, illumination time,supported Ti2 modified fly ash dosage on effects of leachate pollutant removal efficiency. Research shows that in the room temperature range of 20℃ to 30℃ ,irradiation time within 120 min, pH-2,supported TiO2 modified fly ash using acid concentration in 2 mol/L, 500℃ roasted supported TiO2 modified fly ash catalyst of dosage in 30g/L,landfill leachate system of pollutants removal rate is higher.
