Description
技术领域technical field
本发明属于有机污染土壤修复技术领域，具体涉及采用高铁酸钾协同过氧化钙降解土壤洗脱液中六六六的方法。The invention belongs to the technical field of remediation of organic polluted soil, and specifically relates to a method for degrading BHC in soil eluent by using potassium ferrate and calcium peroxide.
背景研究Background Study
随着我国经济的快速发展和工业布局的调整，大量农药厂关停或搬迁，遗留下来的污染场地问题逐渐暴露在大众视野中并得到广泛重视。其中有机氯农药(OCPs)因其具有长期残留性、生物蓄积性、迁移性和高毒性而成为土壤污染场地修复的重点研究对象。OCPs主要六六六(HCH)、滴滴涕(DDT)和六氯苯(HCB)，其中六六六学名六氯环己烷(HCH)，因其高毒性于20世纪60年代末被列入《斯德哥尔摩公约》中的十二大禁药中，其毒性主要是对人体神经系统有较强的危害性，其遗留下的污染场地成为修复重灾区。With the rapid development of my country's economy and the adjustment of industrial layout, a large number of pesticide factories have been shut down or relocated, and the leftover problem of polluted sites has gradually been exposed to the public's vision and received extensive attention. Among them, organochlorine pesticides (OCPs) have become the key research objects of soil contaminated site remediation because of their long-term residue, bioaccumulation, mobility and high toxicity. OCPs are mainly hexachlorocyclohexane (HCH), DDT (DDT) and hexachlorobenzene (HCB), among which the scientific name of HCH is hexachlorocyclohexane (HCH). Among the twelve banned drugs in the Convention, their toxicity is mainly harmful to the human nervous system, and the contaminated sites left by them have become the hardest hit areas for restoration.
目前已有较多的修复有机污染土壤的方法，其中包括：热脱附、气提法和化学氧化法等。但热脱附的产物需要严格控制排放和后处理，成本相对较高；有机氯农药难挥发，因此气提法修复效率较低；化学氧化法具有降解效率高、速度快等优点，成为降解土壤有机污染物的重要方法之一，广泛应用于中度和重度有机氯污染土壤的修复。常用的化学氧化剂有芬顿试剂、臭氧、高锰酸钾、活化过硫酸盐和高铁酸钾等。其中高铁酸钾具有极高的氧化性和选择性，且分解产物主要是Fe(Ⅲ)，不产生二次污染，因此成为环境修复研究和应用的热点。At present, there are many methods for remediating organic polluted soil, including: thermal desorption, gas stripping and chemical oxidation. However, the products of thermal desorption require strict control of discharge and post-treatment, and the cost is relatively high; organochlorine pesticides are difficult to volatilize, so the repair efficiency of air stripping method is low; chemical oxidation method has the advantages of high degradation efficiency and fast speed, and has become a degradable soil One of the important methods for organic pollutants, it is widely used in the remediation of moderately and severely organochlorine-contaminated soils. Commonly used chemical oxidants include Fenton's reagent, ozone, potassium permanganate, activated persulfate, and potassium ferrate. Among them, potassium ferrate has extremely high oxidation and selectivity, and the decomposition product is mainly Fe(Ⅲ), which does not produce secondary pollution, so it has become a hot spot in the research and application of environmental remediation.
近期一些学者的研究表明，过氧化钙具有较强的氧化有机污染物的能力，这是由于过氧化钙可以通过反应产生过氧化氢，过氧化氢可以在过渡金属元素的催化作用下形成类芬顿试剂，产生氧化性较强的·OH，为有机污染物的化学氧化降解创造了条件。过氧化钙与过氧化氢相比，容易贮存和运输，安全性较好，且其释放过氧化氢的速率可控，因此在类芬顿反应中试剂利用率较高。然而，高铁酸钾和过氧化钙在有机土壤修复的应用还很少得到报道，技术上也存在一些困难，主要是因为六六六在土壤中主要吸附于腐殖质上，使得氧化剂与六六六的接触效率相对较低，因此应用化学氧化法修复有机污染土壤存在传质效率差的问题，采用其它氧化剂也存在同样的问题。有学者研究表明，采用表面活性剂可以有效洗脱土壤中的六六六，使得六六六增溶于表面活性剂的胶束中，但表面活性剂只是实现了六六六的解吸，并未使其降解，其生态毒性仍然存在。Recent studies by some scholars have shown that calcium peroxide has a strong ability to oxidize organic pollutants. This is because calcium peroxide can produce hydrogen peroxide through the reaction, and hydrogen peroxide can form phenoids under the catalysis of transition metal elements. Ton reagent produces strong oxidizing OH, which creates conditions for the chemical oxidation degradation of organic pollutants. Compared with hydrogen peroxide, calcium peroxide is easier to store and transport, and has better safety, and its release rate of hydrogen peroxide is controllable, so the utilization rate of reagents in Fenton-like reactions is higher. However, the application of potassium ferrate and calcium peroxide in organic soil remediation has rarely been reported, and there are some technical difficulties, mainly because 666 is mainly adsorbed on humus in soil, which makes the oxidant and 666 The contact efficiency is relatively low, so there is a problem of poor mass transfer efficiency in the application of chemical oxidation to remediate organic contaminated soil, and the same problem exists in the use of other oxidants. Some scholars have shown that the use of surfactants can effectively elute BHC in the soil, so that BCH can be solubilized in the micelles of the surfactant, but the surfactant only realizes the desorption of BCH, and does not Make it degrade, its ecotoxicity still exists.
结合洗脱和化学氧化的优点，可以采用表面活性剂实现土壤六六六的解吸，使其从土壤胶体吸附状态转为游离态，进入土壤洗脱液中，再采用高铁酸钾和过氧化钙协同来降解六六六，从而实现六六六污染土壤的快速高效修复。Combining the advantages of elution and chemical oxidation, the desorption of soil HCH can be achieved by using surfactants, so that it can change from the soil colloidal adsorption state to the free state, enter the soil eluent, and then use potassium ferrate and calcium peroxide to synergize To degrade 666, so as to realize the rapid and efficient restoration of 666-contaminated soil.
经申请人多年研究，本发明公开了一种利用高铁酸钾协同过氧化钙降解土壤中六六六的方法，能够快速高效修复六六六污染土壤。After many years of research by the applicant, the present invention discloses a method for degrading BCH in soil by using potassium ferrate in cooperation with calcium peroxide, which can quickly and efficiently restore BCH-contaminated soil.
