The application of sludge ceramsites in water treatment
The hazards of sludge,the status quo of treatment and disposal,and the preparation process of sludge ceramsites were summarized.The application and mechanism of sludge ceramsites in the adsorption of nitrogen,phosphorus,heavy metals,organic matter and turbidity removal are systematically reviewed,so as to provide a reference for sludge ceramsites in the field of sewage treatment.The limitations of sludge ceramsites in water purification are analyzed,and its future development direction is prospected.
