It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. Due to the high biological density of aquaculture farms, a large number of metabolites, garbage, waste, and corrupt organisms are produced. Most of them are temporarily stored in sewage pools after being collected, which not only pollutes the surrounding environment of the aquaculture farm, but also emits unpleasant odors. It is necessary to use tailwater treatment equipment to treat the tailwater.
