Problems solved by technology

In the fluidized bed wastewater treatment equipment described in this document, the filler is directly put into the fluidized bed reaction tank. Once the system breaks down, it is very difficult to remove the filler and maintain the system.
The filler in this equipment can only adopt the suspension mode, in order to maintain the suspension of the filler, it is necessary to provide sufficient aeration intensity at any time
In addition, this equipment cannot control the movement area of ​​the filler in the reaction tank, which can easily cause a large amount of filler to accumulate at the water outlet, reduce the water treatment efficiency, and cause system blockage, so the use is very limited

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 packing 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.

Abstract

The invention relates to a net cage type biological filler sewage treatment device and a working method and application thereof, and belongs to the field of biological sewage treatment. The device comprises a net cage of a net structure. The net cage comprises a side wall, partition plates, a top cover and a net cage bottom. The net cage bottom is provided with a bottom plate, the top cover is movably connected with the side wall, the side wall is provided with at least one boss, the bottom plate is provided with at least one clamping part, the partition plates are arranged on the bosses or arranged in the clamping parts, and a filler zone is formed among the side wall, the bottom plate and the top cover and contains various kinds of filler. The filler zone can be divided into multiple upper and lower layers or multiple inner and outer zones through the partition plates as needed, different layers or different zones contain various kinds of filler, and the filler can be arranged in a stacked state or a suspended state or a stacked and suspended combination state and is high in combination freedom degree. According to the technical scheme, the problem of non-uniform distribution of filler in a sewage treatment tank is solved, and the device can contain various kinds of filler and can be conveniently installed without extra supports, flexibly stored at various sites and conveniently moved.

Description

Technical field: [0001] The invention relates to a cage-type biological filler sewage treatment device and its working method and application, belonging to the field of sewage biological treatment. Background technique: [0002] Sewage biological treatment is a treatment method that uses the life activities of microorganisms to degrade dissolved or colloidal pollutants in sewage, thereby purifying sewage. It is one of the most widely used methods in modern sewage treatment. [0003] According to the state of microorganisms in the sewage treatment tank, sewage biological treatment can be divided into two categories: suspended growth process and fixed growth process. At present, the most widely used activated sludge process is a typical suspension growth process. In this process, microorganisms are suspended in water, sludge bulking and sludge loss are prone to occur, and it is difficult to recover microorganisms from effluent water for reuse. The fixed growth process uses im...
