摘要
使用臭氧氧化-活性炭吸附联合法处理苯酚废水,分别考察了活性炭投加量、苯酚废水溶液pH值和活性炭吸附反应时间等因素对苯酚模拟废水处理效果的影响。结果表明,室温条件下,废水溶液的pH值为9,臭氧通入时间为25 min,活性炭投加量2.5 g/L,活性炭吸附反应时间为50 min的实验条件下,初始浓度为100.0 mg/L的苯酚模拟废水经过处理,苯酚去除率为95.0%。
The combined method of ozone oxidation and activated carbon adsorption was used to treat phenol wastewater.The effects of the activated carbon dosage,activated carbon adsorption time,and pH value of phenol wastewater solution on the phenol simulated wastewater treatment efficiency were investigated.The results showed that under the experimental conditions of room temperature,wastewater solution pH value was 9,ozone admission time was 25 min,activated carbon dosage was 2.5 g/L,and activated carbon adsorption time was 50 min,the simulated wastewater with an initial concentration of phenol was 100.0 mg/L after treated,the phenol removal rate was 95.0%.
