Abstract

The release of excessive amounts of phosphorus into water bodies causes growth of algae, eutrophication, death of fish and plants, reduction in water quality, depletion of dissolved oxygen, and other serious environmental problems. Technology with high-efficiency treatments is used to alleviate eutrophication in aquatic ecosystems caused by the release of excessive amounts of phosphorus. Amongst the chemical, physical and biological methods used for removing phosphates from water, adsorption technology has proven to be effective even at low concentrations. Even though different adsorbents have been developed with excellent properties, many shortcomings were observed. The first aim of this review is to provide facts on novel adsorbents (including biochar, carbonaceous adsorbent, zeolites, calcium silicate hydrate, and metal oxides) used for phosphate removal. Second, various adsorbents applied for phosphate removal have been compared. Third, based on the aforementioned criteria, the best adsorbents are proposed and this is the key novelty of this review work. Moreover, future aspects and challenges regarding nitrate and phosphate removal are presented.

吸附法高效除磷

向水体中释放过量的磷会导致藻类生长、富营养化、鱼类和植物死亡、水质下降、溶解氧耗尽和其他严重的环境问题。高效处理技术用于缓解因过量磷释放而导致的水生生态系统富营养化。在用于去除水中磷酸盐的化学、物理和生物方法中，吸附技术已被证明即使在低浓度下也是有效的。尽管已经开发出具有优异性能的不同吸附剂，但仍观察到许多缺点。这篇综述的第一个目的是提供用于磷酸盐去除的新型吸附剂（包括生物炭、碳质吸附剂、沸石、硅酸钙水合物和金属氧化物）的事实。其次，对各种用于磷酸盐去除的吸附剂进行了比较。第三，基于上述标准，提出了最佳吸附剂，这是本综述工作的关键新颖性。此外，还介绍了硝酸盐和磷酸盐去除的未来方面和挑战。
