Description
技术领域technical field
本发明涉及水处理技术领域，具体涉及将锌铁二元水滑石作吸附剂去除废水中的卤素离子的应用。The invention relates to the technical field of water treatment, in particular to the application of zinc-iron binary hydrotalcite as an adsorbent to remove halogen ions in waste water.
背景技术Background technique
随着我国经济的发展，我国水污染情况越来越严重。在这样的水环境情况下，人们对水污染处理技术的关注程度越来越高，COD、BOD、氮、磷、重金属等污染物的去除技术得到了极大的发展。目前除了氟化物有相应的排放标准限值外，其他的常见卤素离子并没有排放限制，对其关注度不够，相应的去除技术相对较少。但是工业废水中卤素离子很难被微生物所利用，高浓度含卤素废水如不加治理直接排入江河，会破坏水体的自然生态平衡，使水质恶化，对养殖业、淡水资源造成严重破坏，严重时甚至会污染地下水和饮用水水源。因此研究卤素离子的去除技术对生态和环境保护都很有意义。With the development of my country's economy, my country's water pollution is becoming more and more serious. In such a water environment, people pay more and more attention to water pollution treatment technology, and the removal technology of COD, BOD, nitrogen, phosphorus, heavy metals and other pollutants has been greatly developed. At present, except for fluoride, which has corresponding emission standard limits, other common halogen ions do not have emission limits, and there is not enough attention to them, and there are relatively few corresponding removal technologies. However, halogen ions in industrial wastewater are difficult to be utilized by microorganisms. If high-concentration halogen-containing wastewater is directly discharged into rivers without treatment, it will destroy the natural ecological balance of the water body, deteriorate water quality, and cause serious damage to aquaculture and fresh water resources. It may even pollute groundwater and drinking water sources. Therefore, it is very meaningful to study the removal technology of halide ions for ecological and environmental protection.
目前去除水中卤素离子的方法主要有:溶剂萃取技术、阴离子交换树脂法、复合絮凝剂絮凝处理等方法。溶剂萃取技术主要利用化合物在两种互不相溶(或微溶)的溶剂中溶解度或分配系数的不同，使化合物从一种溶剂内转移到另外一种溶剂中。通过反复多次萃取，可以将绝大部分的化合物提取出来，采用这种方法去除废水中的卤素离子成本比较高，经济上不划算。阴离子交换树脂法、复合絮凝剂絮凝处理方法本质都是通过吸附的方式除掉废水中的卤素阴离子，目前研究重点是在提高吸附材料的效费比上。At present, the methods for removing halogen ions in water mainly include: solvent extraction technology, anion exchange resin method, composite flocculant flocculation treatment and other methods. Solvent extraction technology mainly uses the difference in solubility or distribution coefficient of compounds in two immiscible (or slightly soluble) solvents to transfer compounds from one solvent to another. Most of the compounds can be extracted through repeated extractions. The cost of removing halogen ions in wastewater by this method is relatively high, and it is not economically cost-effective. The anion exchange resin method and composite flocculant flocculation treatment method essentially remove halogen anions in wastewater by adsorption. The current research focus is on improving the cost-effectiveness of adsorption materials.
层状水滑石(LDH)纳米材料是由带正电荷的主体层板(金属氢氧化物)和层间阴离子通过非共价键的相互作用组装而成的。水滑石的层状结构特点使其层间阴离子可与各种阴离子进行交换。目前用锌铁水滑石吸附去除废水中卤素离子的应用未见文献报道。Layered hydrotalcite (LDH) nanomaterials are assembled by non-covalent interactions of positively charged host laminae (metal hydroxides) and interlayer anions. The layered structure of hydrotalcite enables the interlayer anions to be exchanged with various anions. At present, the application of zinc-iron hydrotalcite to adsorb and remove halogen ions in wastewater has not been reported in the literature.

本发明的目的通过以下技术方案实现：a.吸附反应：按吸附剂与废水中所含磷酸根的质量比为(0.2-7)：1的比例，将该吸附剂加入到废水溶液中，磁力搅拌，在25℃温度下反应搅拌(0.5-2)h，滤出吸附剂，检测废水中残留的卤素离子的量；该方法适用于卤素离子的浓度为(0.1-1)M的废水水溶液。(是否还有b技术方案)The object of the present invention is achieved through the following technical solutions: a. Adsorption reaction: the mass ratio of the phosphate radical contained in the adsorbent and waste water is (0.2-7): the ratio of 1, the adsorbent is added in the waste water solution, and the magnetic force Stir, react and stir at 25° C. for (0.5-2) h, filter out the adsorbent, and detect the amount of halogen ions remaining in the wastewater; this method is suitable for aqueous wastewater solutions with a concentration of halogen ions of (0.1-1) M. (Whether there is technical solution b)
优选地，所述在卤素离子的浓度为(0.1-0.5)M的废水中，投加的锌铁比为1:1的二元水滑石，可达到吸附剂的吸附卤素离子的最大吸附量。Preferably, the binary hydrotalcite with a zinc-iron ratio of 1:1 is added to the wastewater with a halogen ion concentration of (0.1-0.5) M to achieve the maximum adsorption capacity of the adsorbent for adsorbing halogen ions.
本发明通过物理与化学作用相结合的方法，通过调节锌与铁元素的比例，实现最大程度的吸附去除废水中卤素离子。The present invention realizes maximum adsorption and removal of halogen ions in waste water by adjusting the ratio of zinc and iron elements through the method of combining physical and chemical actions.
