摘 要：
以碱性大红模拟废水为对象,采用Fe~(2+)和Fe~(3+)作为催化剂与H_2O_2构成芬顿体系进行了Fenton氧化反应,考查了pH值、反应时间、Fenton试剂配比与用量等影响因子对色度处理效果的影响。结果表明:最佳处理条件为:初始pH=3、C(Fe~(2+))∶C(H_2O_2)=1∶5或C(Fe~(3+))∶C(H_2O_2)=1∶5、反应时间为30 min。当碱性大红模拟废水浓度为1000 mg/L,初始H_2O_2浓度为5 mmol/L时,最佳条件下Fe~(2+)、Fe~(3+)芬顿体系的脱色率去除效率分别为92.30%、95.68%。对比了Fe~(2+)和Fe~(3+)作为催化剂进行Fenton氧化反应的处理效果。说明Fe~(3+)作为催化剂与Fe~(2+)效果相近。

摘 要：
Alkaline bright red simulated wastewater was taken as an object; Fe~(2+) and Fe~(3+) were used as catalysts to form Fenton oxidation system with H_2O_2; and the influence factors such as pH, reaction time, Fenton reagent proportion and dosage on chromaticity treatment effect were investigated. The results showed that the optimal treatment conditions were: initial pH=3, C(Fe~(2+))∶C(H_2O_2)=1∶5 or C(Fe~(3+))∶C(H_2O_2)=1∶5, and the reaction time was 30 min. When the concentration of simulated alkaline red wastewater is 1000 mg/L and the initial H_2O_2 concentration is 5 mmol/L, the decoloration rate of Fe~(2+) and Fe~(3+)Fenton systems under the optimal conditions is 92.30% and 95.68% respectively. The effects of Fe~(2+) and Fe~(3+) as catalysts for Fenton oxidation were compared, and the results showed that the effect of Fe~(3+) was similar to Fe~(2+) as catalyst.
