摘要
Abstract
VOCs(volatile organic compounds)waste gas was simulated using cooking oil fumes,and the waste gas was treated using a combined condensation-Fenton oxidation process.After gas-liquid separation,the gas was separately treated by the waste gas treatment system and the waste water treatment system.The waste gas,after being condensed,was adsorbed by secondary activated carbon and then discharged.The waste water generated by condensation was first oxidized by Fenton's reagent,and then discharged through a sand filter and activated carbon filtration.The optimal process conditions for both the waste gas treatment system and the waste water treatment system were determined.Under the conditions of an inlet air flow rate of 160 mL/L,a condensation temperature of-10℃,and an inlet air temperature of 150℃,the removal rate of oil fumes after condensation is 87.99%.When the equipment is connected to liquid nitrogen for condensation,the removal rate of oil fumes increases to 97.41%.Under the conditions of pH 3.0,ferrous sulfate dosage of 0.13 g/L,mass fraction 30%hydrogen peroxide dosage of 0.15 mL/L,reaction time of 50 min,PAC(polyaluminium chloride)dosage of 250 mg/L,and PAM(polyacrylamide)dosage of 2 mg/L,the lowest effluent COD(chemical oxygen demand)reaches 42 mg/L,which is lower than the first-class standard for comprehensive wastewater discharge,and the COD removal rate reaches 73.32%.关键词
