铁碳微电解及芬顿氧化处理某抗生素废水的研究
|
摘要
近几年,铁碳微电解和芬顿氧化法因其对有机物的强氧化性而被广泛用于抗生素废水的预处理。本文以某药业公司抗生素废水为研究对象,以CODcr去除率为评价指标,分别进行了铁碳微电解与芬顿氧化实验。实验发现:将进水p H调节为4,铁碳投加比例控制在1:1(体积比),反应停留时间保持为120min时,铁碳微电解的的去除效果最好;同样,将进水pH调节为4、FeSO4·7H2O和H2O2的投加量分别为1.05g及10m L,反应停留时间保持为120min时,芬顿氧化法的去除效果最好。
In recent years,iron carbon micro-electrolysis and fenton oxidation have been widely used in the pretreatment of antibiotic wastewater due to their strong oxidation of organic compounds.This paper took the antibiotic wastewater of a pharmaceutical company as the research object,and the removal rate of CODcr as the evaluation index,respectively carried out iron carbon micro-electrolysis and fenton oxidation experiments.The results showed that the removal rate of ferrocarbon micro-electrolysis was the best when the wastewater pH of 4,fe-c volume ratio of 1:1,reaction time of 120 min;The optimal reaction parameters of fenton oxidation were:wastewater pH of 4,reaction time of 120 min,and addition amounts of FeSO_4·7H_2O and H_2O_2 were 1.05 g and 10 mL,respectively.
