Study on Treatment of Waste Water of Synthetic Detergent by Ultraviolet Light/Fenton Reagent

Ultraviolet light/Fenton reagent process is used in deep treatment of waste water of synthetic scourage. The effecting factors such as the quantity of H_2O_2 and FeSO_4·7H_2O 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:Fe~(2+)44.5mg/L,H_2O_2 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.
