摘要
随着污水处理厂出水标准的提高,基于生物载体的污水处理工艺逐渐得到广泛应用。概述了生物载体应用于污水处理的相关研究进展,总结了生物载体比表面积大、孔隙率高、生物亲和性好的共同特性,梳理了生物载体在不同污水处理工艺的应用效果和作用机制。在此基础上,综述了微细粉末载体、硫自养脱氮等新型生物载体强化污水处理最新研究进展,并探讨了生物载体强化污水处理性能的优化机理,包括提高生物量、强化传质过程、生物膜微环境、富集功能微生物等机制。通过对生物载体在污水处理最新研究进展进行分析讨论,以期为新型高效生物载体的开发与应用提供参考。
With the improvement of effluent standards of sewage treatment plants,sewage treatment processes based on biological carriers have gradually been widely used.The related research progress of biological carrier applied to sewage treatment is summarized.The biological carriers are characterized by large specific surface area,high porosity,and good biocompatibility.The application effect and mechanism of biological carrier in different sewage treatment processes are sorted out.On this basis,the latest research progress of new biological carriers such as fine powder carriers and sulfur autotrophic denitrification to enhance wastewater treatment are reviewed.The optimization mechanism of biological carriers to enhance wastewater treatment performance is discussed,including increasing biomass,enhancing mass transfer processes,Mechanisms of biofilm micro-environment and enrichment of functional microorganisms.Through the analysis and discussion of the latest research progress of biological carriers in sewage treatment,this study hopes to provide a reference for the development and application of new high-efficiency biological carriers.
