Biological contact oxidation tank and product introduction

As the habitat of microorganisms, biological filler is the carrier of biofilm, which not only affects the growth, reproduction and shedding of organisms, but also plays an important role in the properties of biofilm, oxygen utilization and hydraulic distribution conditions, and is the key factor that directly affects the treatment effect of biological contact oxidation process. Process flow: key points of design: A: anaerobic hydrolysis tank

Characteristics and origin of biological contact oxidation method

The characteristics of the biological contact oxidation method are that the aerobic biofilm method uses fillers with high porosity and large specific surface area immersed in water to provide an interface for microbial attachment and growth. It has the characteristics of activated sludge process and is different from other biofilm processes. The contact aeration method in foreign countries has evolved due to the use of high porosity filler, large specific surface filler and comprehensive

Among the influencing factors of An/O biological phosphorus removal process, influent COD/TP and BOD load of biochemical reaction system are key. The test results show that the larger the COD/TP is, the more anaerobic phosphorus release is, which is more conducive to phosphorus removal. The amount of anaerobic phosphorus release is a function of the amount of absorbed COD; Moreover, the change of influent COD/TP will not significantly affect the removal of system COD
