Embodiment 1
[0044] A net cage type biological filler sewage treatment device, comprising a net cage, the net cage is a mesh structure, the net cage includes a side wall, a partition, a top cover and the bottom of the net cage, the bottom of the net cage is provided with a chassis, the top cover and the side wall Flexible connection, a packing area is formed between the side wall, the chassis and the top cover, and the packing area is used to accommodate the packing with microorganisms in various shapes, properties and states; in this embodiment, the side wall is provided with 8 bosses, and the bottom plate There is one clamping piece, and the partition is set on the boss. In this embodiment, the partition is used to divide the packing area into upper and lower layers; different layers can accommodate a variety of packing, and the packing can be in a piled state, a suspended state or The combined state arrangement of stacking and suspension, such as Figure 1-4 as shown, figure 1 , figu...
Embodiment 2
[0049] A cage-type biological filler sewage treatment device, its structure is as described in Embodiment 1, the difference is that the chassis is provided with 4 clamping parts, the partition is arranged in the clamping part, the clamping part is a concave part, and the partition Located in the recess of the clamping piece, the clamping piece is used to fix the partition. In this embodiment, the partition is used to divide the filling area into two areas, such as Figure 5 As shown, different zones can accommodate various kinds of fillers. For the pattern of internal and external partitions as in this embodiment, it is generally not necessary to do upper and lower layering, otherwise the stability of the internal partition is not high.
Embodiment 3
[0051] A kind of cage-type biological filler sewage treatment device, its structure is as described in embodiment 1, the difference is that a high-density polyethylene circular handle with an inner diameter of 8 cm is respectively provided at the top of the side wall along the four corners, so as to facilitate the netting. Placement and movement of tanks in the sewage system.
