摘　　要：研究了水热辅助Fenton试剂氧化法对中和沉淀-气浮工艺处理后的显影废水的深度处理效果和影响因素。结果表明，在最佳反应条件下，当进水CODcr为300—400mg／L时，处理出水COD。〈60mg／L，达到《污水综合排放标准》（GB8978--1996）～级标准要求。在实验条件下，最佳反应参数为：初始pH为2．5，反应温度为110℃,FeS047H20投加质量浓度为3．6g／L，30％H202投加质量浓度为3．3—3．7g，L，反应时间为1-2h。水热辅助Fenton试剂氧化法的CODc1。去除率可汰Rs．2％．The advanced treatment efficiency and influencing factors of hydrothermal-assisted Fenton reagent oxidation method on the development wastewater pretreated by neutral precipitation-flotation process have been investigated. The results show that under the optimum condition,i.e, when the influent CODcr is 300-400 mg/L,the effluent CODcr is less than 60 mg/L,meeting the requirements of the first grade Comprehensive Standard of Wastewater Discharge （GB 8978--1996）. Under the experiment conditions, the optimal operating parameters are as follows ： initial pH is 2.5, reaction temperature 110℃, FeSO4＂ 7H2O dosage 3.6 g/L, 30%H2O2 dosage 3.3-3.7 g/L, and reaction time 1-2 h. The removing rate of CODcr by hydrothermal-assisted Fenton reagent oxidation method reaches 85.2%.
