土壤因子对阿特拉津吸附动力学及其污染土壤微生物修复的影响

除草剂阿特拉津已经对中国北方农田土壤产生了较高的污染风险，对其有效的原位修复已成为研究热点。微生物修复技术因具备高效、廉价、生态友好等优势，利用其进行阿特拉津污染土壤的原位修复逐渐受到广泛关注。本文从土壤成分、酸碱度、物理结构、养分水平等方面，分别详尽的阐述了土壤因子对阿特拉津的吸附-解吸动力学、功能微生物的增殖与活力的影响。同时，也为今后增强微生物原位修复效果提出了一些可行的建议和方案。总之，本文可为污染土壤生物修复方式的因地制宜选择与推广奠定理论基础，也为进一步强化微生物原位修复污染土壤的效果提供理论指导。

Effects of Soil Factors on Atrazine Adsorption Kinetics and Microbial Remediation of Contaminated Soil

The herbicide atrazine has caused high pollution risk to farmland soil in north China, and the effective in-situ remediation of atrazine pollution has become a research hotspot. Due to the advantages of high efficiency, low cost and being environment-friendly, microbial remediation technology has received widespread attention to remediate atrazine contaminated soil in-situ. In this paper, the effects of soil factors on the kinetics of atrazine adsorption-desorption, as well as the proliferation and vitality of functional microorganisms were summarized from the aspects of soil texture, pH, physical structure, nutrient level and so on. Meanwhile, some feasible suggestions and schemes were proposed to enhance the results of in-situ microbial remediation in the future. In conclusion, this paper can lay a foundation for the selection of bioremediation measures for contaminated soil according to local conditions, and provide theoretical guidance for strengthening microbial remediation of contaminated soil in-situ.
