摘　　要：经反渗透系统处理后的脱盐水,化学需氧量(COD)有时需要进一步处理,因为有机物含量较低,无法依靠生物处理去除,所以研究针对脱盐水的有效处理技术非常重要。本文研究了絮凝、芬顿(Fenton)和Fenton-絮凝三种不同高级氧化工艺在不同条件(剂量、时间)下,对脱盐水的COD和总无机碳(IC)的氧化去除作用。结果表明,反应时间为2 h的传统Fenton工艺的出水COD最低(32.4 mg/L),COD去除率最高,该研究有望提供一种处理脱盐水的有效方法。The desalted water treated by the reverse osmosis system sometimes requires further treatment in terms of chemical oxygen demand(COD)removal due to its low organic content,which cannot be removed by biological treatment.Therefore,it is crucial to study effective technologies for desalted water treatment.This paper investigates the oxidation and removal effects of COD and total inorganic carbon(IC)in desalted water under different conditions(dosage,time)using three different advanced oxidation processes:flocculation,Fenton,and Fenton-flocculation.The results show that the traditional Fenton process with a reaction time of 2 hours has the lowest COD value in the outlet water(32.4 mg/L)and the highest COD removal rate.This study is expected to provide an effective way for treating desalted water.
