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,CODCr质量浓度达15000mg/L。一种可行的、有效的去除油墨废水中的有机成份的方法对印制电路板生产废水总体的CODCr达标至关重要。在此探讨了光助Fenton(UV-Fenton)法中m(FeSO4·7H2O):m(H2O2)配比、pH值、反应温度和紫外光光照时间等因素对油墨废水处理CODCr效果的影响,并进行了光助Fenton法和酸化凝聚法处理油墨废水CODCr的实验比较。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 （CODCr） may reach 15 000 mg/L. A feasible and effective method for eliminating the organics of the ink wastewater is very important to the total CODCr of the wastewater in the printed circuit board manufacturing process up to the standard. This article discussed the eftect of some treating factors that included the dosage ratio of FeSO4·TH2O and H2O2, the pH value, the reaction temperature and the UV light time in the UV-Fenton treatment process. At the same time, the contrast experiments of treating CODCr of the ink wastewater in the printed circuit board manufacturing process were studied.
