摘　　要：我国许多地区水域普遍受到了微污染,通常表现为水体氨氮浓度升高水中有机污染增多、溶解氧下降、藻类滋生等。当该类水体作为市政供水水源时.采用常规水处理工艺难以达到饮用水水质要求,增加生物预处理是一个必要的措施。生物接触氧化是一种简便易行的工艺,广泛应用于污水处理给水预处理。通过对生物接触氧化工艺原理及影响因素进行介绍,调研了生物接触氧化工艺在市政给水处理方面的应用情况,着重考察了代表性工程案例的设计参数及对污染物的去除效果,分析了该工艺在应用过程中需注意的主要问题,对生物接触氧化工艺在给水预处理方面的未来研究热点进行展望。Waters in many areas are generally micro-polluted,usually manifested as increased ammonia nitrogen concentration and organic pollution in the water body,decreased dissolved oxygen,and algae growth.It's necessary to increase biological pretreat-ment as conventional water treatment processes can't meet the drinking water quality requirements,when micro-polluted water is used as a municipal water supply source.Biological contact oxidation process is simple and easy to implement,and is widely used in sewage treatment and water supply pretreatment.Principle and influencing factors of the biological contact oxidation process were in-troduced,the application of the process in municipal water supply was also investigated.This essay also described the design parame-ters and the removal efficiency of representative engineering cases using biological contact oxidation process,and summarized the main issues that need to be pay attention to.At last,the further future research hotspots of the biological contact oxidation process was given.
