摘　　要：采用高锰酸钾预氧化-缺氧/好氧生物铁法处理维生素B1厂乙酰嘧啶生产段实际废水,实验结果表明该组合工艺对嘧啶生产废水具有良好的处理效果：预氧化将嘧啶废水中大分子难降解乙酰嘧啶几乎全部转化为具有饱和碳氢键的小分子有机物,使乙酰嘧啶去除率达90%以上,且COD去除率在40%以上,BOD5/COD由0.17-0.23提高至0.35-0.44。通过与后续A/O生物铁工艺相结合,使COD、TN和氨氮总去除率分别达到93.3%、81.7%和78.6%,出水pH为6.6-7.5。Potassium permanganate preoxidation-anoxic/aerobic bio-ferric process was established to treat the acetyl primidine wastewater of vitamin B1 production plant.Preferable effects were acquired from the combinatorial process： almost all the refractory acetyl pyrimidine were converted into small molecule organics,which contained saturated carbon-hydrogen bond only after the preoxidation pretreatment;the removal efficiency of acetyl pyrimidine was above 90%,and COD removal efficiency was above 40%;BOD5/COD enhanced from 0.17～0.23 to 0.35～0.44.The results got from the process which combined pretreatment with biological treatment were as follows： total removal efficiency of COD,TN and NH＋4-N was 93.3%,81.7% and 78.6%,respectively,and effluent pH value was 6.6～7.5.
