【摘要】：以某城市污水處理廠剩余污泥為原料,磷酸為活化劑,采用微波輻照活化法制備污泥活性炭,用FT-IR,DSC,ASAP 2010對其結(jié)構(gòu)進(jìn)行了表征.以甲基紫為吸附質(zhì),考察了其吸附性能.結(jié)果表明,在磷酸濃度為30%、微波輻照時(shí)間為4min、微波功率為464 W時(shí),其碘吸附值為302mg/g,比表面積為81.5m2/g.污泥活性炭對甲基紫的吸附等溫方程同時(shí)符合Langmuir和Freundlich方程,應(yīng)用假一級(jí)和假二級(jí)反應(yīng)動(dòng)力學(xué)模型對實(shí)驗(yàn)數(shù)據(jù)進(jìn)行擬合,發(fā)現(xiàn)污泥活性炭吸附甲基紫更符合假二級(jí)反應(yīng)動(dòng)力學(xué)方程.
[Abstract]:Activated sludge was prepared by microwave irradiation from excess sludge of a municipal wastewater treatment plant with phosphoric acid as activator. The structure of activated sludge was characterized by FT-IRN DSC-ASAP 2010. The adsorption properties of methyl violet were investigated. The results show that the iodine adsorption value is 302 mg / g and the specific surface area is 81.5 mg / g when the phosphoric acid concentration is 30 and the microwave irradiation time is 4 minutes and the microwave power is 464 W. The adsorption isotherm equation of methyl violet from activated carbon of sludge accords with both Langmuir and Freundlich equations. The experimental data are fitted by pseudo-first-order and pseudo-second-order reaction kinetic models. It was found that the adsorption of methyl violet by activated carbon of sludge was more in line with the kinetic equation of pseudo-secondary reaction.
