摘要
采用辐射分解法处理废水中的苯酚 ,分别测定了辐照时间 ,剂量率 ,苯酚起始浓度 ,溶液pH及加入H2 O2 对苯酚去除率的影响。结果表明 ,去除率随辐照时间的延长而提高 ;总剂量一定的条件下 ,低剂量率下苯酚降解完全 ;当苯酚浓度较低时 ,去除效果较好。pH为中性条件下的去除率大于酸性和碱性 ;加入一定浓度的H2 O2 可使苯酚的去除率达到 1 0 0 %。
Phenol in wastewater was decompounded by radiation, on which the effects of radiation time, dose rate, phenol original concentration, pH value, and adding H 2O 2 were observed. The result showed: decomposition rate rise as radiation was conducted. When total does was definite, phenol was decompounded entirely at lower does rate. The lower was the concentration of phenol, the easier was the decomposition. The decomposition rate was higher at pH equal 7 than at acidity and alkalescence. The existence of H 2O 2 promotes decomposition up to 100%.
