This paper provides a comprehensive overview of the adsorption efficiency, mechanism, and modified materials of attapulgite (AT) in removing phosphorus from fresh water. It also explores the potential of using AT as a filler in constructed wetlands (CWs) to enhance phosphorus removal from mariculture wastewater. Additionally, the sources and pathways of nutrients leading to eutrophication of coastal waters are summarized, along with the contribution of mariculture to coastal eutrophication and the application prospects and existing challenges of CWs in treating mariculture wastewater. The paper also identifies the initial problems and possible solutions when using AT as a filler in CWs for phosphorus removal from mariculture wastewater, and proposes future research directions.
Recently, attapulgite (AT) as an adsorbent to remove phosphorus from eutrophic water and sediment have progressively become a burgeoning research field. Herein, an in-depth overview of the adsorption efficiency, mechanism and modified materials of AT on phosphorus in fresh water is presented. The prospect using AT as the filler of constructed wetlands (CWs) to enhance phosphorus removement from mariculture wastewater are prospected. Meanwhile, the sources and pathways of nutrients causing eutrophication of coastal waters are summarized. The contribution of input nutrients from mariculture to eutrophication of coastal waters is clarified, and the application prospect and existing problems of CWs in treating mariculture wastewater are discussed. Moreover, the paper points out the problems and solutions that need to be solved first when AT is used as the filler of CWs to remove phosphorus from mariculture wastewater. The outlooks of future research directions are also proposed.
