摘要:
采用离子交换树脂(强酸型阳离子交换树脂、强碱型阴离子交换树脂)研究实验室含汞废水的处理方法,讨论了废水pH、氯离子、EDTA共存状态下对离子态汞去除作用的影响,得出:(1)氯离子的存在会抑制强酸型阳离子交换树脂对废水中汞离子的吸附作用,会改善强碱性阴离子交换树脂对汞离子的吸附作用;(2)EDTA能与汞离子结合形成稳定的配合物,在pH 6~10的情况下,配合物能被强酸型阳离子交换树脂彻底吸附,出水中的总汞浓度远低于废水中汞的排放标准限值;(3)当模拟废水中EDTA与氯离子共存时,EDTA能与汞离子优先结合形成配合物,该配合物能被强酸型阳离子交换树脂彻底吸附,出水中的总汞浓度远低于废水中汞的排放标准限值;(4)废水中汞的最佳去除方法为:将废水的pH调节至6~10,在足量的EDTA存在下,采用强酸型阳离子交换树脂可以完全去除废水中的汞,从而实现出水的达标排放.
Abstract:
Ion exchange resin(strong acid cation exchange resin and strong base type anionexchange resin)was used to study the treatment method of mercury-containing wastewater inlaboratory, and the impact factors of pH, chloride ion,EDTA were discussed, and some conclusions were drawn as follows.(1)The presence of chloride ions inhibits theadsorption of mercury ions in wastewater by strong acid cation exchange resin, however, theadsorption of mercury ions by strongly basic anion exchange resins is improved.(2)EDTA cancombine with mercury ions to form a stable complex.At pH 6-10, the complex can be completelyadsorbed by strong acid cation exchange resin.The total mercury concentration in the effluentis much lower than the mercury discharge standard limit in wastewater.(3)When EDTA andchloride ions co-exist in simulated wastewater, EDTA can preferentially combine with mercuryions to form a complex.This complex can be completely adsorbed by strong acid cation exchangeresin.The total mercury concentration in the effluent is much lower than the mercurydischarge standard value in wastewater.(4)The best way to remove mercury from wastewater isto adjust the pH of the wastewater to 6-10.In the presence of a sufficient amount of EDTA,the use of strong acid cation exchange resin can completely remove the mercury from thewastewater and achieve effluent discharge standards.
