Process for Enhancement of Fluidized Bed Biofilm Treatment Efficiency through Bio-Agglomeration Treatment

摘要

The present invention relates to a process for enhancing the treatment efficiency of highly degradable high concentration wastewater.;It is difficult to expect good treatment efficiency in a method where the high concentration of degradable wastewater is supplied only to the aeration tank, as in the conventional activated sludge method, so that decomposition by microorganisms is mostly performed in the aeration tank. In order to increase the decomposition efficiency of such a high concentration, hardly degradable wastewater, it is a process that enables the biological treatment of the return sludge in the semi-collecting tank.;The biggest feature of the present invention is that the decomposition by microorganisms is performed in only one place of aeration tank in the conventional method, and in the present invention, since it is made in two places of the sump tank and the fluidized bed biofilm method, it is possible to increase the treatment efficiency of high concentration hardly degradable wastewater. In addition, it is possible to increase the treatment efficiency without using a separate site or cost because it uses the existing collection tank.
