This study was designed to explore the adsorption capacity of natural zeolite on Escherichia coli K88(E. coli K88)under different conditions as adsorption time, pH value, zeolite dosage. The result showed that zeolite had adsorption capacity for the Escherichia coli K88. The saturated adsorption capacity of zeolite was observed after 60 min. The maximum adsorption rate of E. coli K88 on zeolite reached 90%at pH value of 6 and dosage of 20 mg/mL.%研究了在不同吸附时间、pH值、沸石添加量下天然沸石对大肠杆菌K88的吸附效果。结果表明，沸石对大肠杆菌K88有一定吸附能力，沸石与细菌作用60 min后吸附达到饱和，在pH值为6、沸石添加量为20 mg/mL时吸附率最大，可达90%。
