【摘要】 重金属污染成为日益严重的环境污染问题，也是影响污水资源化利用的关键因素，城镇污水处理厂污染物排放标准严格限制了重金属的最高允许排放浓度。对城镇污水厂处理污水中的重金属和微生物吸附去除重金属等相关研究进行整理，阐述了城镇污水中的重金属浓度和特性、重金属离子在污水处理厂的迁移转化、不同处理工艺对典型重金属的去除效能以及影响因素和典型去除机理，并对未来污水厂去除重金属研究进行了展望。更多还原

【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.更多还原
