The release of endogenous phosphorus (P) from sediments is the main cause lake eutrophication, even after successful control exogenous P. Among others, iron-bound P a major source P, and it necessary to reduce concentration by enhancing iron–phosphorus binding. Iron (Fe)-modified biochar adsorption an effective widely used method for fixing in sediments. In this paper, modification method, mechanism, application effect Fe-modified are reviewed. It found that most methods realized through physicochemical pathway. Therefore, prospect biological pathway presented. particular, possible iron-oxidizing bacteria (IOB) promoting binding modifications discussed. potential effects additions on microbial communities water also future research, emphasis should be placed mechanism analysis simulated polluted environments before large-scale use, ensure economic practicability sustainability applications.

Combining Multiple Remediation Techniques Is Effective for the Remediation of Eutrophic Flowing Water

Water, Journal Year: 2024, Volume and Issue: 16(6), P. 858 - 858

Dredging, adsorbent inactivation, and phytoremediation are commonly used to control internal nitrogen phosphorus sediment loads in eutrophic still-water ecosystems, such as lakes ponds. However, the effectiveness of these remediation techniques has not been verified for rivers, lakes, reservoirs with large disturbances. In this study, a calcium-loaded clay granular (CRB) was prepared an alternative commercial adsorbents, experiment conducted on ecological restoration effects both dredging single treatments well combined flowing water. The enhancement effect above investigated. results indicated that CRB inactivation treatment reduced turbidity water by 63% 80%, respectively increased total permanganate index (CODMn) 25% 101% before phytoremediation, compared group. There were no significant differences nutrient indexes between group, but enhanced treatment. Compared treatment, CODMn decreased 13% 15%, respectively. Phytoremediation significantly improved treatments, individually combination. Additionally, there notable growth rates submerged plants contents different speciation among plant species. Selecting suitable species is recommended when implementing methods. This study highlights combination multiple effective provide guide
