摘要:
采用混凝法分别联合芬顿(Fenton)和O3氧化法深度处理焦化废水的生化尾水。通过单因素实验分析,分别研究聚合硫酸铝铁(PAFC)、H2O2以及O3的投加量对化学耗氧量(COD)、总氮(TN)以及苯酚处理效果的影响,并通过紫外-可见光吸收光谱(UV-Vis)分析废水中有机污染物的降解机制。结果表明:当PAFC投加量为2 000 mg/L时,混凝法对COD、TN以及苯酚的去除率分别为10.19%、2.36%以及2.13%; 当H2O2投加量为0.07%时,Fenton强化混凝法对COD、TN以及苯酚的去除率分别为81.08%、22.49%以及95.84%; 当O3投加量为1 000 mg/L时,O3强化混凝法对COD、TN以及苯酚的去除率分别达到82.63%、30.29%以及100%,对废水起到了良好的净化效果。
Abstract:
Advanced processing of biochemical tail water for coking wastewater using coagulation combined with Fenton or O3 was investigated. Effects of PAFC dosage, H2O2 dosage, and O3 dosage on chemical oxygen demand(COD), total nitrogen(TN), and phenol treatment effects were studied by single factor experiments, and the mechanism of organic pollutants degradation in wastewater was revealed by UV-Vis. The experimental results indicated that when the PAFC dosage was 2 000 mg/L, the removal rates of COD, TN and phenol by the coagulation method were 10.19%, 2.36% and 2.13% respectively; when the dosage of H2O2 was 0.07%, the removal rates of COD, TN and phenol by Fenton enhanced coagulation method were 81.08%, 22.49% and 95.84% respectively; when the dosage of O3 was 1 000 mg/L, the removal efficiency of COD, TN and phenol by O3 enhanced coagulation method were 82.63%, 30.29% and 100% respectively, which greatly improved the biodegradability of wastewater.
