摘　　要：为了进一步了解p H值、Fe2+与H2O2投加量、反应时间与反应温度等因素对Fenton体系的影响机理,试验采用Fenton法,以养猪场与屠宰场废水为处理对象,进行了色度去除影响因素优化试验。结果表明:处理100 m L废水,养猪场废水色度去除最佳p H值、Fe2+与H2O2投加量、反应时间与反应温度分别为3,2.8×10-4mol Fe SO4/(倍·L)与1.4×10-1mol H2O2/(倍·L)、90 min、25℃,屠宰场为5,9.0×10-6mol Fe SO4/(倍·L)与6.0×10-3mol H2O2/(倍·L)、90 min、20℃,此时两种废水最佳色度去除率分别为77%与98%。To further know the influencing mechanisms of pH value, the dosing of Fe2＋ and H2 02 , reaction time, temperature and other factors on Fenton system, the wastewater from pig farm and slaughterhouse was treated to optimize the influencing factors on chroma removal using Fen- ton method. The results showed that the optimum pH values of chroma removal, the dosing of Fe2 ＋ and H2 02 , and the reaction time with reaction temperatures for the wastewater from pig farm and slaughterhouse when treating 100 mL wastewater were 3 and 5, 2.8 x 10 -4 mol FeSO4 and 1.4 x 10 - 1 mol H2 02 （ degree ·L）, 90 rain with 25 ℃ and 90 min with 20℃, respectively. At this moment the optimum chroma removal rates of two kinds of wastewater were 77% and 98% respectively.
