摘要

摘要: 有机废物制备生物炭技术近年来已在多领域成为研究热点。以市政污泥(MS)为原料通过热解制备生物炭(MS-BC),利用红外扫描光谱(FT-IR)、扫描电子显微镜(SEM)、能谱分析(EDS)和比表面积分析(BET)对MS-BC进行表征,并将其用于吸附去除四环素,考察了制备条件和操作条件对MS-BC吸附四环素性能的影响。研究结果表明:高温热解制备的MS-BC1000孔隙结构发达,比表面积大,可提供较多的吸附位点,吸附性能良好。当投加量(m_(MS-BC))为0.3 g,吸附时间(t)为4 h,吸附温度(T)为25 ℃,振荡频率(v)为200 r/min,初始pH值为6,初始浓度(C₀)为50 mg/L时,四环素去除率可达到98.5%左右,Langmuir吸附等温模型和Lagergren准二级动力学方程可以较好地拟合四环素在MS-BC的吸附行为,以单分子层化学吸附为主,通过键的极性相互作用和π-π 相互作用吸附到MS-BC表面,最大吸附量可达到333.3 mg/g。该成果可为市政污泥的资源化利用和四环素抗生素废水的处理提供理论依据。

Abstract: In recent years, the preparation of biochar from organic waste has become a research hotspot in many fields. In this paper, biochar (MS-BC) was prepared from municipal sludge (MS) by pyrolysis, and then characterized by FT-IR, SEM, EDS, and BET. The effect of preparation and operation conditions of MS-BC on its adsorption of tetracycline was investigated. The result showed that, the MS-BC1000 prepared by high-temperature pyrolysis has developed a pore structure with a large specific surface area, and can provide abundant adsorption sites and excellent adsorption performance. The removal rate of tetracycline by MS-BC 1000 was about 98.5%, at the MS-BC dosage of 0.3 g, the adsorption time of 4 h, adsorption temperature (T) of 25 ℃, the oscillation frequency (V) of 200 r/min, the initial pH of 6, and the initial tetracycline concentration (c₀) of 50 mg/L. Langmuir adsorption isotherm and Lagergren’s quasi-second-order kinetic equation can better explain the adsorption behavior of tetracycline on MS-BC, mainly due to the monolayer adsorption by polar interaction and π-π interaction. The maximum adsorption capacity was 333.3 mg/g. The findings provide a theoretical basis for the reuse of municipal sludge and the treatment of tetracycline antibiotic wastewater.
