Abstract

In China, soil heavy metal pollution is becoming more and more serious, and supramolecular nanomaterial adsorbents are very effective in the treatment of heavy metal pollution in acid selenium-rich soil environments. Pollution control related research is essential. The purpose of this article is to solve the problem of pollution control of heavy metals in the acid selenium-rich soil environment in southern China. By understanding the existing methods of pollution control of heavy metals in the soil environment, especially the use of supramolecular nanomaterial adsorbents to control the pollution of heavy metals in the soil Methods and related principles, and then conducted a detailed investigation and research on the application of existing supramolecular nanomaterial adsorbents in the treatment of heavy metal pollution in acid selenium-rich soil environment. The research results show that the use of supramolecular nanomaterial adsorbents to treat heavy metal pollution in acid selenium-rich soil environment is very effective. The acid selenium-rich soil treated with supramolecular nanomaterial adsorbents not only reduces the exogenous selenium fertilizer The amount of application, but also reduces the food selenium caused by the application of exogenous selenium fertilizer, safety risks and environmental selenium poisoning caused by improper application of selenium fertilizer, verified by experiments, the quality of contaminated soil treated by supramolecular nanomaterial adsorbent The index increased by 15% and the crop harvest rate increased by 20%.

摘要

在我国，土壤重金属污染日益严重，超分子纳米材料吸附剂在治理酸性富硒土壤环境中的重金属污染方面非常有效。污染控制相关的研究是必不可少的。本文旨在解决我国南方酸性富硒土壤环境中的重金属污染治理问题。通过了解现有的土壤环境重金属污染控制方法，特别是利用超分子纳米材料吸附剂控制土壤重金属污染的方法和相关原理，然后对现有的超分子纳米材料吸附剂在酸性富硒土壤环境中重金属污染治理中的应用进行了详细的调查研究。研究结果表明，利用超分子纳米材料吸附剂处理酸性富硒土壤环境中的重金属污染非常有效。超分子纳米材料吸附剂处理过的酸性富硒土壤，不仅减少了外源硒肥的施用量，还减少了外源硒肥施用造成的食物硒、硒施用不当造成的安全隐患和环境硒中毒肥料，经实验验证，
