      2,4-dichlorophenol degradation.

AB  - The effect of the photo-Fenton process on biodegradability enhancement of 100 mg 
      x L(-1) aqueous 2,4-dichlorophenol (2,4-DCP) solution has been investigated. An 
      initial concentration of 65 mg x L(-1) H2O2 and 10 mg x L(-1) Fe (II) during 35 
      minutes of irradiation time was sufficient for total 2,4-DCP removal. At these 
      working conditions, biodegradability, measured as BODS/COD ratio, was increased 
      from 0 for the original solution up to 0.15. Biological oxidation of photo-Fenton 
      pre-treated solutions was performed in a sequencing batch reactor (SBR). After 32 
      days of start-up, the reactor was fed with different pre-treated solutions and 
      cycle duration was reduced progressively. TOC removal efficiencies in the SBR 
      went from 30 up to 70%.
