摘　　要：微生物在废水处理中发挥着至关重要的作用,通过生物降解和生物转化,可以有效去除废水中的有机物、氮、磷元素,以及重金属等污染物。废水处理中用到的微生物主要包括细菌、真菌和藻类,它们在不同处理系统中发挥着关键作用,如活性污泥系统、生物膜系统和废水生物稳定塘等。微生物处理效果的评估指标包括化学需氧量(COD)和生化需氧量(BOD)的去除率、氮磷去除效率,以及重金属和有毒物质的去除效率。Microorganisms play a crucial role in wastewater treatment,and can effectively remove pollutants such as organic compounds,nitrogen,phosphorus,and heavy metals from wastewater through biodegradation and biotransformation processes.The main microorganisms used include bacteria,fungi,and algae,which play a role in different treatment systems,such as the activated sludge system,the biofilm system,and the wastewater biological stabilization pond.The evaluation methods for microbial treatment effectiveness include the removal rates of chemical oxygen demand(COD)and biochemical oxygen demand(BOD),nitrogen and phosphorus removal efficiency,and the removal efficiency of heavy metals and toxic substances.
