The use of modified coal gangue for the remediation and ...

The excessive discharge of nitrogen and phosphorus and the release of sediment lead to the overgrowth of algae and other aquatic plants, a lack of oxygen in water bodies, and, ultimately, the eutrophication of water bodies (van Dael et al. 2020; B. Li et al. 2019a, b).In some lakes, some nitrogen elements are reduced to nitrogen or nitrous oxide with denitrification and leave the water body.
