  • 摘要: 采用絮凝法与电絮凝法对低浓度放射性含铀废水的处理进行了对比研究。结果表明:絮凝法除铀的主要影响因素是pH和絮凝剂投加量,在pH为7.0、PAC投加量为300 mg·L-1、搅拌速度为45 r·min-1的条件下,铀去除率达97.94%；电絮凝法除铀的主要影响因素是pH和电流密度,在pH为5.0、电流密度2.4 mA·cm-2、通电时间24 min的条件下,铀去除率达99.11%；电絮凝法除铀动力学特征符合一级动力学模型,在不同pH条件下的线性相关系数均大于0.91。絮凝法和电絮凝法水处理成本分别为0.61元·t-1和0.45元·t-1,絮体产生量分别为258 g·t-1和171.5 g·t-1。采用絮凝法和电絮凝法均可实现废水中铀的高效去除,但电絮凝除铀工艺较传统絮凝法具有易自动化控制、处理成本低、絮体产生量低等优点,具有较好的推广应用前景。
    Abstract: The purification of uranium (Ⅵ) containing wastewater with the low uranium concentration using flocculation and electrocoagulation process was investigated in this study. The results showed that solution pH, the additive dosage of flocculant were the main factors affecting the removal of uranium with flocculation method. At the experimental conditions of solution pH 7.0,dosage of PAC 300 mg·L-1, stirring speed 45 r·min-1, the uranium removal efficiency was 97.94%. As for uranium removal with electrocoagulation process, solution pH and applied current density would significantly affect the uranium removal efficiency. At the experimental conditions of solution pH 5.0,current density 2.4 mA·cm-2 the uranium removal efficiency could reach 99.11% within 24 min bulk electrolysis. The uranium removal from water with electrocoagulation process followed the first-order kinetics mode, the correlation coefficients at different pH conditions were greater than 0.91. The treatment costs and the amount of generated flocs of wastewater with flocculation and electrocoagulation were 0.61 yuan·t-1 and 258 g·t-1, 0.45 yuan·t-1 and 171.5 g·t-1, respectively. Using flocculation and electrocoagulation method would both realize the efficient removal of uranium from uranium polluted wastewater, but compared to the traditional flocculation process, uranium removal with electrocoagulation process has the advantages of easy automation, low treatment cost, low floc yield, so it has a good prospect of popularization and application.
