  • 摘要: 采用两级絮凝-活性炭吸附法处理实验室无机废水,研究了该方法对重金属、硫化物、挥发酚、苯胺和浊度等的处理效果。结果表明,在絮凝温度、搅拌、曝气及污水pH值调节范围一定的情况下,硫酸亚铁(FeSO4·7H2O)与聚合氯化铝(PAC)结合的二级絮凝方法能有效地降低污水中的重金属和硫化物等污染物。二级絮凝处理中,使用聚合氯化铝(PAC)对一级絮凝中去除效果不好的Cr6+的去除效果显著,去除率达到90％以上;活性炭对苯胺和硫化物的去除效果最佳,去除率都在90％以上。同时,该方法还有效降低了废水的浊度和色度。因此,是一种快速、低成本和工艺简单的处理实验室废水的有效途径。
    Abstract: In this study, the technologic method of two-stage flocculation and active carbon absorption were applied to treat inorganic wastewater from laboratory, and the its treatment efficiencies for the heavy metals,sulfide,volatile phenol,aniline and turbidity were investigated. The results showed that the method of two-stage flocculation combined with Ferrous sulfate (FeSO4·7H2O) and polymerization aluminium (PAC) effectively reduced the content of pollutants such as heavy metals, sulfides, etc., in the sewage under a certain conditions of flocculating temperature, stirring, aeration and pH. Removal efficiency of Cr6+ in the secondary flocculation processing used polymerization aluminium (PAC) was apparently better than in the primary flocculation, and the removal rate was over 90%. The removal efficiencies of aniline and sulfide were best in the treatment of adsorption by activated carbon, the removal rate achieved more than 90%. Additionally, this treatment method effectively reduced the wastewater’s turbidity and chromaticity. Therefore, the method of two-stage of flocculation and active carbon absorption to treat inorganic laboratorial wastewater is an effective way with the characteristics of rapid, low cost and simple.
