摘　　要：以广州市供水安全体系中珠江航道备用水源作为对象,研究其在突发事故情况下,即西江水遭受突发事件切换使用备用水源时,高速给水曝气生物滤池(BAF)作为其生物预处理环节的联合常规处理的应急能力。结果表明,高速BAF联合常规处理具有良好的抗冲击负荷能力:切换水源48～72 h之后,预处理出水氨氮的质量浓度稳定在1～2 mg.L-1,最终砂滤池出水氨氮的质量浓度稳定≤0.5 mg.L-1;切换水源后数小时内滤池中的亚硝酸盐菌和硝酸盐菌在生长速率和转化能力上已协调稳定,反应器内硝化类细菌驯化效果良好;COD预处理平均去除率在45 h后稳定在15%～20%,砂滤池的最终出水在48 h之后<4 mg.L-1;浊度平均去除率稳定在29.9%。This article is based on the Backup water source of Zhujiang Channel of the Guangzhou water security system,and study the emergency capability of the high-speed water supply BAF as the Biological Pretreatment with the conventional ways.That is to switch the Backup water source when the water in Xijiang is caught in the emergency.The simulation of the emergency treatment of Zhujiang spare high pollution raw water test shows that the high-speed filter with the conventional ways has a good resistance to impact load capacity： after 48～72 h of switching water,Ammonia Nitrogen of the Biological Pretreatment basically reaches 1～2 mg·L-1,the Sand filter basically reaches ≤0.5 mg·L-1;switching water within hours,the nitrite bacteria and nitrates bacteria in the filter is already coordination stable in the growth rates and conversion capacities.The reactor nitrification kinds of bacteria domesticated effect is good.After 45 h,the average removal of COD is stable in 15%～20% while the average removal turbidity is 29.9%.
