摘　　要：采用Fenton氧化—吹脱法进行了兰炭废水预处理试验研究,分别考察了COD、色度和氨氮的去除效果及其影响因素。结果表明,处理100 mL的兰炭废水时,Fenton氧化的最佳工艺条件为:30%的H2O2投加量为40 mL、n(H2O2)∶n(Fe2+)=20、pH=6;吹脱除氨的最佳工艺条件为:温度为60℃、pH=11;在此条件下,Fenton氧化—吹脱法对COD、色度和氨氮的去除率分别达到了95.72%、95%和88%,废水的可生化性提高了4～5倍。The research on Fenton oxidation combined with ammonia stripping for semi-coking wastewater pretreatment has been studied.The influential factors and removal efficiencies of COD,chroma and ammonia-nitrogen are investigated.When the water sample volumn is 100 mL,the results show that the optimal conditions of Fenton oxidation are as follows： the dosage of H2O2 is 40 mL,n（H2O2）∶n（Fe2＋）=20,and pH=6.Ammonia stripping technical conditions are： temperature=60 ℃,and pH=11.Under these conditions,the removal rates of COD,chroma and ammonia-nitrogen can reach 95.72%,95% and 88%,respectively.The biodegradability is improved by 4 to 5 times.
