在间歇式反应器中，采用光- fenton氧化法在室温下处理纺织废水。考察了溶液初始pH （pH = 1 ~ 7）、亚铁离子浓度（0 ~ 100 mg×l）和紫外功率（0 ~ 120 W）对化学需氧量（COD）和去色的影响。结果表明，在酸性pH范围内，这一过程得到了加强。最佳条件为pH = 3, 80 mg Fe×l, 5-10 min， 60 W紫外功率，200 mg h2o2 ×l。在此条件下，COD去除率约为52%，颜色去除率约为90%。处理过程中产生少量污泥（5.8×10 kg×kg COD）。tio2等非均相光催化剂的存在加快了COD的去除率和颜色的去除率。
Treatment of textile wastewater was carried out at room temperature in a batch reactor by using the Photo-Fenton oxidation process. The effects of initial pH of the solution (pH = 1-7), ferrous ion concentration (0-100 mg×l) and UV power (0-120 W) on chemical oxygen demand (COD) and color removal were examined. The results showed that this process was enhanced at the acidic pH range. The optimum condition was found to be at pH = 3, 80 mg Fe×l, 5-10 minutes operating time, 60 W UV power and 200 mg H 2 O 2 ×l. At this condition, approximately 52% and 90% of COD and color were removed, respectively. During the treatment process, a small amount of sludge (5.8×10 kg×kg COD) was generated. The presence of heterogeneous photocatalyst such as TiO 2 in the system accelerated the removal percentage of COD and color.
