摘　　要：近年来,MBBR工艺在污水厂提标改造工程中有较多运用。辽宁省朝阳市净源污水厂中水回用工程将悬浮链式曝气生物池改造为MBBR池,有效提高了氨氮和TN去除率,使得出水水质由一级B标准提高至一级A标准。归纳总结了该生物池改造的设计参数及要点,可供相关工程参考。In recent years, MBBR process has been widely applied in upgrading projects of wastewater treatment plant. In the Jingyuan wastewater recycling and reuse project in Chaoyang City, Liaoning Province, the suspended chain aeration tank was changed to MBBR tank in order to promote the effluent water quality. As a result, the ammonia nitrogen and TN removal efficiency have been improved greatly, and the effluent quality was enhanced from class B to class A of the first level. The design parameters and key points were discussed in detail, which could be used as reference for other similar projects.
