污泥复合生物炭的制备及其吸附性能研究

Gongye shui chuli
基于污泥的资源化利用潜力和生物质材料含碳量高的特点，以市政污泥为主要原料，通过分别掺入核桃壳、小麦秸秆和竹粉作为增碳剂，采用干混和浸渍两种方式制备出一系列复合生物炭，考察了制备方法及制备条件对所制备复合生物炭吸附性能的影响。结果表明，以核桃壳为增碳剂，将市政污泥经3 mol/L ZnCl2浸渍活化后于400 ℃炭化条件下制备得到的生物炭具有最佳吸附性能，其比表面积为336.5 m2/g，对初始质量浓度为50 mg/L的亚甲基蓝（MB）的吸附率可达到99.47%，碘吸附值为632 mg/g ...

酸改性酒糟生物炭对Cr（Ⅵ）的去除性能研究

Gongye shui chuli
利用白酒酒糟制备生物炭，采用KHCO3活化后，再利用酸溶液浸渍进行改性，制备了酸改性酒糟生物炭（H-BC）。对H-BC的制备参数（热解温度、活化剂比例、改性酸种类及浓度）进行优化，得到热解温度为700 ℃，酒糟生物炭与活化剂（KHCO3）为1∶1.5，采用0.5 mol/L硝酸改性制备的H-BC对Cr（Ⅵ）的吸附性能最优。探讨了初始pH（2.0~6.0）、初始Cr（Ⅵ）质量浓度（100~600 mg/L）、吸附时间（0~27 h）、吸附温度（20~60 ℃）、背景离子等因素对H-BC吸附Cr（Ⅵ ...
