Biological Fluidized Bed Treatment Of Pharmaceutical Wastewater

Biological Running Bed is a new kind of wastewater treatment with high efficiency, It can be applied to all kinds of biological wasterwater. A lot of research work on Pharmaceutical wastewater was conducted to find out the most suitable time parameter of treatment, PH , loads on different carrieres (the carrieres in the first stage are X-I and X-2 , that in the second stage is Y) and more efficient anaerobiosis-aerobics process. The removal efficiencies of COD~ in the first stage without preprocessor,with preprecossor, are respectively above 91% (averagely 92.86%) , above 94% (averagely 95.07%) ; The removal efficiency of CC)Da in the second stage is above 94.5%( averagely 95.4%). On this basis, a comparison was made between SBR and Biological Running Bed on the ability of CODCr removal from Kunnung Pharmaceutical wastewater, FlIRT . The study results showed the latter is more efficient, shorter and more resistant. Otherwise, this paper not only discusses the relative of BOLl)5 and CODa , character of wastewater and the possibilities of Biology, but also describes the law of microbial action , builds the kinetic models of biochemical reaction with assistance of computer. The paper finally discusses the action of PFS which can prove the quality of out-water. Biological Running Bed has its special features. its application to Pharmaceutical wastewater states clearly that this process is ideal and has many virtues such as less-room, high efficiency strong shock resistance.
