摘要
采用连续动态试验,以铁炭复合材料为反应介质,对含铜黄连素制药废水进行处理,考察了复合材料的基本特征及其对含铜黄连素废水的处理效率。结果表明,对进水pH为2.3～3.0,初始Cu2+浓度约为410mg/L,初始黄连素浓度约为35mg/L的含铜制药废水,当水力停留时间(HRT)为1.0h时,出水中黄连素浓度低于1.0mg/L,Cu2+浓度低于0.5mg/L。该复合材料经再生后可重复用于含铜废水处理,并可保证出水效果。扫描电镜(SEM-EDS)显示,再生后的复合材料表面结构及Fe-Cu两种元素所占比例与废水处理前铁炭复合材料基本一致。UV-vis光谱结果表明,铁炭复合材料可有效去除废水中黄连素等污染物。
Fe/C composite materials were used to treat the pharmaceutical wastewater containing copper through a continuous reactor. The characters of Fe/C composite materials and the performance to berberine wastewater containing copper were investigated in details. The results showed that the berberine and Cu^2＋ concentrations in effluent were reduced from 35 and 410 mg/L to lower than 1.0 and 0.5 mg/L respectively under the conditions of hydraulic retention time of 1.0 h and the initial pH of 2.3-3.0. The Fe/C composite material could be regenerated and reused for treatment of wastewater containing copper and the effluent effect could be guaranteed. The X-ray energy dispersive spectroscopy （EDS） results showed that the surface structure of the regenerated composite materials and the proportion of Fe-Cu elements were consistent with those of the raw composite material before wastewater treatment. The UV-vis results showed that berberine could be effectively removed by iron-carbon composite materials.
