摘要和关键词

摘要: 傍河区域是地表水与地下水相互作用的关键带,为解决该交互带内氮污染修复问题,文章融合缓释氧材料和液态碳源的作用,通过构建室内矩形槽试验,分析缓释氧材料和碳源梯级修复傍河地下水氮污染效果与机制。结果表明,缓释氧材料和碳源的激发作用可以显著增强傍河区微生物的硝化和反硝化作用,溶解氧质量浓度可以增大5倍,氨氮和硝酸盐氮的去除率分别达到91%、94%,且硝化反应和反硝化反应主要集中在各自反应区域的前1/4至1/3段,验证了采用融合缓释氧材料和液态碳源开展梯级修复方法处理傍河地下水氮污染的可行性和有效性。

Abstract and Keywords

Abstract: The riverside area is a key zone where surface water and groundwater interact. In order to solve the problem of nitrogen pollution remediation in this interaction zone, this paper combined the effects of slow-release oxygen materials and liquid carbon sources, and analyzed the effect and mechanisms of slow-release oxygen materials and carbon sources on the cascade remediation of riverside groundwater nitrogen pollution by constructing an indoor rectangular slot experiment. The results show that the activation of slow-release oxygen materials and carbon sources can significantly enhance the nitrification and denitrification of microorganisms in riverside area. The concentration of dissolved oxygen can be increased by five times, and the removal rates of ammonia nitrogen and nitrate nitrogen can reach 91% and 94%, respectively. In addition, the nitrification and denitrification reactions are mainly concentrated in the first 1/4 to 1/3 of their respective reaction zones. The results indicate the feasibility and effectiveness of the cascade remediation of riverside groundwater nitrogen pollution using slow-release oxygen materials and liquid carbon sources.

Keywords: riverside groundwater; nitrogen pollution remediation; slow-release oxygen materials; liquid carbon sources
