Characteristics of biofilm and its rapid start-up mode; The relationship between biological oxidation function and filtration function; The shedding law of biofilm during backwashing; Further broaden the application scope of biological aerated filter, and study how to combine it with other processes in advanced water treatment, micro-pollution source water treatment, refractory organic matter treatment, low-temperature sewage nitrification and low-temperature micro-pollution water treatment.
The research on the core medium filter material of biological aerated filter will also promote the application scope of this process in China. Both BIOSTYR and Biofor have strong functions, but there are still some problems in their wide application in China, such as patent problems and large investment, which also hinder their wide application in China.
Therefore, the research and localization of special filter materials will be the key to the wide application of biological aerated filter in China.
