摘要
针对高浓度难降解ABS废水,采用微波-活性炭-Fenton法进行处理。试验探讨了活性炭投加量、微波辐照时间、微波功率、pH值、H2O2投加量以及Fe2+与H2O2物质的量比等因素对COD和浊度去除率的影响,并将微波-活性炭-Fenton法与Fenton法、单独微波法、活性炭吸附法和微波-Fenton法进行比较。结果表明:在室温条件下,采用微波-活性炭-Fenton法处理100 mL的ABS废水,最优条件为:pH值为3、H2O2投加量为2.4 mL、Fe2+与H2O2物质的量比为1∶15、活性炭投加量为1.0 g、微波功率为600 W、辐照时间为180 s,此时COD去除率达到90.7%。对比试验表明,微波-活性炭-Fenton法对ABS废水具有更优的处理效果。
As ABS wastewater is characterized by high concentration and hard degradability,microwave-activated carbon-Fenton process was adopted for its treatment.The influence of activated carbon dosage,time and power of microwave irradiation,pH value,H2O2 dosage,Fe2+/H2O2 mass ratio and some other factors on COD and turbidity removal,were investigated through tests,and then,the comparison among microwave-activated carbon-Fenton combined process,Fenton process,single microwave process,activated carbon adsorption and microwave-Fenton process were carried out.The results showed that:using microwave-activated carbon-Fenton process to treat 100 mL of ABS wastewater at room temperature,the optimal condition was as follows:the pH value was 3,the H2O2 dosage was 2.4 mL,the mass ratio of Fe2+to H2O2 was 1∶15,the activated carbon dosage was 1.0 g,the microwave power was 600 W,the irradiation time was 180 s,the removal rate of COD reached 90.7%.The comparative test indicated that,microwave-activated carbon-Fenton process had better treatment efficiency on ABS wastewater.
