【摘要】 采用紫外光辅以Fenton试剂对合成洗涤剂废水进行深度处理。通过试验 ,讨论了H2 O2 、FeSO4·7H2 O的量、pH值、紫外光波长、光照时间的影响 ,选定了最佳条件 :Fe2 + 浓度为 4 4 .5mg/L ,H2 O2 浓度为 16 5 6mg/L ,溶液的pH值为 3,紫外光波长范围 2 4 0～ 30 0nm。并进一步做了循环式流动态试验 ,为合成洗剂废水的深度处理提供了依据。更多还原

【Abstract】 Ultraviolet light/Fenton reagent process is used in deep treatment of waste water of synthetic scourage. The effecting factors such as the quantity of H₂O₂ and FeSO₄·7H₂O used,pH value,the wavelength of ultraviolet light ,the irradiation time with ultraviolet light etc. obtained through experiment are discussed. The optimal operation conditions are selected as follows:Fe²⁺44.5mg/L,H₂O₂ 1656mg/L , pH value 3 and the wavelength of ultraviolet light 240～300nm. Dynamic experiments of circulating flow is carried out so as to provide the scientific basis of deep treatment of waste water of synthetic detergent.更多还原
