摘　　要：沼液成分复杂,比较难处理。Fenton试剂法可以在反应中产生活性极强的羟基自由基,能无选择性地矿化有机污染物。采用Fenton试剂催化降解沼液,分别研究在不同pH值、不同催化剂投加量、不同H_(2)O_(2)投加量、不同Fe^(2+)投加量及不同反应时间等实验条件下对沼液降解效果的影响,确定Fenton试剂催化降解沼液的最佳反应条件。实验结果标明:当pH值为3时,H_(2)O_(2)的浓度为15 mL/L,Fe^(2+)的浓度为130 mg/L,反应时间控制在2 h,为催化降解沼液的最佳运行条件,沼液中的COD去除效果最好。The Fenton reagent method can produce hydroxyl radical with strong activity in the reaction.It can indiscriminately mineralize organic pollutants to produce carbon dioxide.Biogas slurry is difficult to be treated because of its poor biodegradability,high concentration of NH3-N and complex composition.This paper studied the effects of Fenton reagent on biogas slurry degradation in different pH values,different dosage of Fe^(2+),different dosage of H_(2)O_(2)and different reaction time.The experimental results showed that when the pH value was 3,the concentration of H_(2)O_(2)was 15 mL/L,the concentration of Fe^(2+)was 130 mg/L,and the reaction time was controlled at 2 h.For the optimal operation conditions of catalytic degradation of biogas slurry,the COD removal effect in biogas slurry was the best.
