The Apply of Solid Flux in The Secondary Sedimentation Tank to Biological A/O Process Enhanced by Zeolite

The theoretical basis of solid flux and the its application in the design and operation control of secondary sedimentation tank was analyzed.According to the analysis of a pilot plant test,it showed that solid flux method could be used to judge whether the running and control of the secondary sedimentation tank was right.The analysis of solid flux could be used to change the operation condition when the loading rate was changed so as to ensure the normal running of the secondary sedimentation tank.
