The project was Highway Toll Station's sewage treatment projects in Qinghai province and its flow was 3.0 m^3/h. Immobilized microorganism technology and biological membrane technology integration were used in the project and the device was buried integrated processor. The standard of effluent wastewater achieved two level emission standards of "Integrated Wastewater Effluent Standard" (GB8978-1996). At the same time, it had advantages of stable and reliable operation, low operation cost, simple management, less sludge, unoccupied floor, etc., in addition, it was worth to be widely applied in similar circumstances.%本工程是青海省菜高速公路收费站流量为3．0m^3／h的生活污水处理工程。采用的处理工艺是微生物吲定化技术与，扛物膜技术相结合的工艺，所用装置为地埋式一体化处理器。处理效果达到了《污水综合排放标准》（GB8978．1996）二级排放标准，同时具有运行可靠稳定、运行费用低、管理简单、所产污泥少、不占用地等优点，值得在相似情况下推广应用。
