Title: Study on the Biofilm Formation Process of Biofilter in a Closed Seawater Recirculating Aquaculture System
Abstract: A simulation recirculating seawater aquaculture system was established,and experiments on the inoculation and operation of the biofilter were conducted to explore the formation process of biofilm on the surface of support packing in biofilter.The changes of fixed biomass concentration and removal efficiency of ammonia and nitrite were examined.Results indicated that the periodicity of the process was 30—35 days and could be divided into 4 stages: the incubating period,the growing period,the stabilizing period and the falling period.The natural plant packing and high influent ammonia concentration were favorable for the formation process of biofilm.
