Description

一种三氧化二铁催化处理有机污染物的方法
技术领域
本发明属于污水处理领域，一种三氧化二铁催化处理有机污染物的方法，可应用于生活污水深度处理及工业废水处理。
背景技术
目前废水处理最常用的生物法对可生化性差、相对分子质量从几千到几万的物质处理较困难，而化学氧化可将其直接矿化或通过氧化作用提高该类污染物的可生化性，同时还对环境类激素等微量有害化学物质的处理方面有很大的优势。化学氧化法是利用化学氧化剂的强氧化性，将废水中的无机物和有机物彻底氧化成无毒的小分子物质或气体，从而达到处理的目的。常见的化学氧化剂为O3、H2O2、ClO2、和K2FeO4等，这些氧化剂通常情况下都是强氧化剂，在溶液中可以氧化多种有机污染物。然而，却仍然存在氧化能力不强且有选择性等缺点，难以满足要求。
三氧化二铁等由于价廉易得，且具有较稳定的物理化学性质，受到研究者的广泛关注。传统的三氧化二铁催化需要辅以双氧水、臭氧等氧化性物质以达到催化降解有机污染物的目的。氧化剂消耗较大，降解速度慢，不能满足工业降解要求。
发明内容
本发明的目的是为克服现有技术中三氧化二铁处理污染物的不足，提供一种三氧化二铁催化处理有机污染物的方法。
为此，本发明提供了以下技术方案，一种三氧化二铁催化处理有机污染物的方法，依次包括如下步骤：
向1L待处理的水中加入0.1～0.5mL甲酸，再加入0.3～1g三氧化二铁，搅拌30～45min，沉淀分离，即可将待处理水中的有机物去除。
该方法利用甲酸与三氧化二铁反应，迅速产生高活性物质，实现对水中有机物的快速去除，相比三氧化二铁吸附或在其他氧化性物质帮助下处理污染物，这种去除的速度快而且不需要消耗氧化性物质。
与现有的水处理氧化方法相比，具有以下优越性：(1)本发明所使用的催化剂三氧化二铁，是安全稳定的固体试剂，运输方便且价格低廉，不需要额外的处理单元。(2)催化剂可以回收并重复利用，甲酸生成二氧化碳溢出，无二次污染。(3)该反应条件温和，无需调节pH值。
具体实施方式
下面结合实施例来详细说明本发明，但本发明并不仅限于此。
实施例1
向1L浓度为20mg/L亚甲基蓝溶液中加入0.1mL甲酸，再加入0.3g三氧化二铁，搅拌45min，沉淀分离，亚甲基蓝的去除率为97.5％，三氧化二铁可以重复利用。在相同条件下，如果不加入甲酸，有机物的去除率为5.2％。
实施例2
向1L浓度为20mg/L罗丹明B溶液中加入0.5mL甲酸，再加入1g三氧化二铁，搅拌30min，沉淀分离，亚甲基蓝的去除率为96.8％，三氧化二铁可以重复利用。在相同条件下，如果不加入甲酸，有机物的去除率为4.1％。
实施例3
向1L浓度为25mg/L金橙II溶液中加入0.2mL甲酸，再加入0.5g三氧化二铁，搅拌35min，沉淀分离，金橙II的去除率为96.9％，三氧化二铁可以重复利用。在相同条件下，如果不加入甲酸，有机物的去除率为5.6％。
