Treatment of arsenic-containing soil
Thread Content
How to quickly treat soil containing arsenic, which is an environmentally friendly process and can solve the problem of soil remediation. Thanks!
For the treatment of contaminated soil, the most common method in China at present is incineration, which can treat a variety of pollutants.； As for a specific element, a solvent elution process can be developed. Organic solvents or aqueous solutions of surfactants can be used. ； Regarding arsenic, remember that there is a hyperaccumulator plant "centipede grass", which is good at enriching it.
Reply 2# holmes8519 Thank you! consult: For arsenic-containing soil, why not use incineration? Or what are the advantages and disadvantages of burning soil containing arsenic?
Generally, this can be done by first oxidizing chlorine (hypochlorous acid) into priceless arsenic, which makes it soluble, and then leaching, and then processing the eluent.
It’s not that the incineration method is not possible. In fact, the main domestic technology at present is incineration. The soil treated by this method will fix the arsenic in the soil, thus achieving the purpose of restoration. Advantages of incineration method: Fast and widely applicable, it can be used for both organic pollution and heavy metal pollution. Disadvantages: The cost is high and it is an ex-situ treatment technology. The surface structure is damaged and soil functions are lost. These pros and cons are my humble opinion, please correct me if there is anything wrong! Thanks! In addition, I would like to recommend a blog. It is not my blog, but I also found it online. http://blog.sina.com.cn/s/articlelist_1728215443_0_1.html Hope it helps you
