摘要:
在通过形成复合锰氧化物去除地下水中氨氮和锰的工艺中，针对非循环系统中生成复合锰氧化物的需水量巨大、生产成本高的问题，将非循环系统改为循环水定期更新系统和循环水持续更新系统，对比循环系统和非循环系统形成的复合锰氧化物对氨氮和锰的去除效果以及滤料膜的增长规律。结果表明，循环水定期更新系统的除锰能力最强，3种不同系统均能够有效去除氨氮；循环水定期更新系统中的成熟滤料去除氨氮和锰时有一段适应期；投加高锰酸钾阶段和成熟滤料去除氨氮与锰时，循环水定期更新系统中滤料膜负载量增长得最快。
Abstract:
In the process of removing ammonia nitrogen and manganese from groundwater by forming composite manganese oxides, the non-circulating system was replaced with the circulating water regular renewal system and continuous renewal system, to address the significant water demand and high production costs associated with generating composite manganese oxides in non-circulating system. This study compared the efficacy of composite manganese oxides in removing ammonia nitrogen and manganese in both circulating and non-circulating systems, as well as the dynamics of oxide film growth. The circulating water regular renewal system exhibited the highest capacity for manganese removal, while all three systems demonstrated effective ammonia nitrogen removal capabilities. An adaptation period occurred when ammonia nitrogen and manganese was removed by the mature filter media in the circulating water renewal system. During the stages of adding potassium permanganate and removing ammonia nitrogen and manganese with mature filter media, the oxide film load on filter media of the circulating water regular renewal system exhibited the most rapid increase.
