BIOLOGICAL TREATING TECHNOLOGY TO REMOVE PHENOLS IN FCCU EFFLUENT
@@Baesd on the survey in 1997 fiscal year, we have been making a further survey and study together with 中国石油(Petro China) at Liaohe Refinery since 1998 fiscal year, aiming at the transfer of Japanese waste water treating technologies to China. Scope is as follows: （1） Demonstration of a new waste water treating technology, a kind of biological treating methods (Fluidized bed biological treatment), to eliminate phenols in FCCU effluent. （2） Recommendation of eliminating pollutant and reducing total effluent by improving the operation. 1 Fluidized bed biological treatment1.1 What is fluidized bed biological treatment Fluidized bed biological treatment is the process to treat waste water as follows: (1) To put biologically inert granular matters (fluidized carrier) into an aeration tank; (2) Homogeneously and entirely to fluidize the particles in the tank to form highly active biofilm on the surface of each particle; (3) To contact organic substances with these microorganisms to purify the waste water. The surface area of the particle per unit volume is about ten times as large as that in conventional biofilm treatment process. In addition, no blockade of the filler (carrier) may be caused. Accordingly, volumetric loading of the aeration tank can be improved to attain highly efficient treatment.
