Abstract:

With the continuous development of the number and scale of urban sewage treatment plants, treatment and resource utilization of sewage sludge have become a hot issue in the field of environmental protection. The preparation of magnetic nanoparticles/sludge composite for the treatment of pollutants in the water environment was one of the important directions of sludge recycling, which could achieve the dual purpose of sludge resource utilization and environmental remediation. The preparation methods, the experimental methods of adsorption, the main factors affecting the adsorption capacity of magnetic nanoparticles/sludge composite and the adsorption mechanism were summarized. The future development and research direction of magnetic nanoparticles/sludge composite as adsorbent were prospected.

Key words: sewage sludge, magnetic nanoparticles, composite, adsorption
