采用铁碳—芬顿组合工艺处理含氯酚模拟废水,对比铁碳—芬顿工艺与单一芬顿在相同进出水条件下芬顿药剂的消耗量,以及最优加药条件下铁泥的产生量,考察铁碳对芬顿在药剂消耗量和铁泥产生量上的改进效果。结果显示:在进水COD为200mg/L,氯酚为50mg/L的条件下,以COD≤60mg/L,氯酚的去除率≥99.9%为处理目标,铁碳—芬顿组合工艺与单一芬顿相比,H2O2的用量减少25%,FeSO4·7H2O的用量减少50%,产生的铁泥量减少约17%,降低了芬顿药剂和铁泥处置的成本。
The iron-carbon-Fenton combination process was applied to treat chlorophenol simulated wastewater. The consumption of Fenton’s reagent under the same inlet and outlet water conditions and iron sludge generation under the optimal dosing conditions were compared between Fe-Fenton process and single Fenton process The effect of iron and carbon on Fenton’s dosage and iron sludge production was investigated. The results showed that under the conditions of influent COD of 200mg / L and chlorophenol of 50mg / L, COD ≤ 60mg / L and removal rate of chlorophenols ≥99.9%, the combination of iron carbon-Fenton process and single Compared to Fenton, the use of H2O2 was reduced by 25%, the amount of FeSO4 · 7H2O was reduced by 50% and the amount of iron sludge produced was reduced by about 17%, reducing the cost of Fenton’s agent and iron sludge disposal.
