摘　　要：油墨废水占印制电路板生产废水总排水量的5%左右,是一种高浓度的有机废水,化学需氧量指标值COD可达15 000 mg/L。一种可行的、有效的去除油墨废水中有机成份的方法对印制电路板生产废水总体的COD达标至关重要。本文探讨了光助Fenton（UV-Fenton）法中FeSO4.7H2O与H2O2的用量配比、pH值、紫外光光照时间和反应温度等因素对油墨废水COD处理效果的影响。The proportion of the ink wastewater in the total wastewater of the Printed Circuit Board manufacturing process is about 5%.The ink wastewater is one kind of highly concentrated organic wastewater,and the Chemical Oxygen Demand wastewater（COD） may reach 15000mg/L.A feasible and effective method for eliminating the organic ingredient of the ink wastewater is very important to the total COD of the wastewater in the Printed Circuit Board manufacturing process.This article discussed the effect of some treating factors that include the dosage ratio of FeSO4·7H2O and H2O2,the pH value,the UV light time and the reaction temperature in the UV-Fenton treatment process.
