【摘要】 利用ClO₂氧化/粉煤灰吸附协同体系对一实际含酚废水进行了处理实验研究。结果表明,对于COD为250mg/L、浓度为30mg/L的1000mL含酚废水,当溶液的pH=5.5,ClO₂用量40mg/L,粉煤灰吸附用量2.0g,在合适的反应和吸附时间下,处理后的废水COD<100mg/L,酚浓度<0.5mg/L,达到了国家有关排放要求。本文同时对二者的协同机理进行了理论上的探讨。更多还原

【Abstract】 Experiments on treating phenol wastewater with cooperation action of ClO₂ oxidation and fly ash adsorption were carried out.Results showed that,on the conditions:pH=5.5,ClO₂=40mg/L,fly ash=2.0g,at the optimal reaction time and the adsorption time,the COD and the concentration of phenol of wastewater（original COD=250mg/L,and the concentration of phenol was 30mg/L） is less than 100mg/L and 0.5mg/L after treating,respectively,which reached the state standard of phenol wastewater discharge.Furthermore,mechanisms on cooperation action of ClO₂ and fly ash were discussed in the paper.更多还原
