Connection, biologic packing material is suspended in one-level filter tank and two grades of filter tanks, and the dividing plate upper end between two grades of filter tanks and three-level filter tank is fixed
Biologic packing material grid, micropore bushing is fixed in the lateral cross section of three-level filter tank, and three-level filter tank is divided into upper and lower two parts.
The blast aerator that the utility model is related to includes air blower and aerator, and aerator is arranged on first-level filtering
Pond and two grades of filter tanks bottom, air blower are connected with aerator, and the box side top near one-level filter tank is fixedly installed into water
Mouthful, the box side bottom near three-level filter tank is fixedly installed delivery port, water inlet and delivery port by pipeline respectively with water inlet
Pump is connected with water pump is gone out.
The biologic packing material that the utility model is related to accounts for one-level filter tank and two grades the four of filter tank volume for suspended biological filler
2/1 mono- to three, preferably 1/3rd.
Compared with prior art, the utility model has advantages below：(1) biochemical reaction path is extended, is effectively reduced
Harmful substance in water, such as organic matter and ammonia nitrogen；(2) more than 5mg/L is reached by the dissolved oxygen amount in the Posterior circle water of three-level filter tank,
Fish normal need is substantially met, the oxygenation capacity to follow-up culturing pool is reduced.
Brief description of the drawings：
The BAF principle schematic diagram. that Fig. 1 is related to for the utility model.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description：
Embodiment 1：
As shown in figure 1, the BAF that the present embodiment is related to includes casing 1, one-level filter tank 2,3, two grades of filters of dividing plate
