Abstract:
Heavy metal pollution has become an increasingly serious environmental pollution problem, and it is also a key factor affecting the utilization of sewage resources. The pollutant discharge standards of urban sewage treatment plants strictly limit the maximum allowable discharge concentration of heavy metals. The related researches on heavy metals in urban sewage and their removal by microbial adsorption are reviewed. The concentration and characteristics of heavy metals in urban sewage, the migration and transformation of heavy metal ions in sewage treatment plants, the influence of different treatment processes on the removal efficiency of typical heavy metal, the influencing factors of heavy metals in treatment processes and the typical removal mechanism were reviewed. Finally, the future research on the heavy metal removal in sewage treatment plants is prospected.
