AB  - The combination of solar irradiation and Fenton reagent have been used to enhance 
      the biodegradability (BOD(5)/COD) of chlorophenol wastewater, including 
      2-chlorophenol (2-CP), 4-chlorophenol (4-CP), and 2,4-dichlorophenol (2,4-DCP). 
      Results showed that the solar photo-Fenton process improved significantly the 
      biodegradability of chlorophenol wastewater. Basically, increasing initial 
      H(2)O(2) dosage was much more beneficial for increasing biodegradability of 
      wastewater than increasing initial Fe(2 + ) dosage. Among the conditions studied, 
      the optimum condition of increasing biodegradability of chlorophenol wastewater 
      was found with a [H(2)O(2)](0)/[Fe(2 + )](0)/[chlorophenol](0) ratio of 
      10.0/0.2/1.0, 10.0/0.3/1.0, and 10.0/0.2/1.0 for 2-CP, 4-CP, and 2,4-DCP, 
      respectively. As a result, the value of BOD(5)/COD was increased from 0 for 
      untreated solution up to 0.231, 0.248, and 0.193 for 2-CP, 4-CP, and 2,4-DCP, 
      respectively with a 15-min treatment. Under the operation of optimum conditions, 
      the oxidative state of chlorophenol wastewater could be easily controlled into a 
      higher biodegradability stage. The COD and TOC degradation efficiency could be in 
      excess of 90% on the whole as the preoxidized chlorophenol solution was treated 
      by a following batch-type biological unit. In the meanwhile, the microtoxicity of 
      wastewater reduced more than 95%.
