The adsorption efficiency of nitrogen and phosphorus by in-situ remediation of modified sediment composite material

Dredged sediment can occupy a large amount of land area, resulting in waste of land resources, and high disposal costs. In response to the problem, this work calcinates and modified the sediment and compounds it with the modified water purification plant sludge, zeolite powder, and bentonite. This i...
