[0027] Refer to Figure 1 , for the long fiber bundle packing component, both ends of a number of long fiber bundles 2 are respectively suspended on an upper support 1 and a lower support 4. The upper support 1 and the lower support 4 are meshes, the planar shapes of the upper support 1 and the lower support 4 are square, and the upper support 1 and the lower support 4 are installed on a bracket 3 to form a hexahedral packing component. The bracket 3 is a cube frame.
[0028] Refer to Figure 2 , for the long fiber bundle packing component, both ends of a number of long fiber bundles 2 are respectively suspended on an upper support 1 and a lower support 4. The upper support 1 and the lower support 4 are meshes, the planar shapes of the upper support 1 and the lower support 4 are square, and the upper support 1 and the lower support 4 are installed on a bracket 3 to form a hexahedral packing component. The bracket 3 is a cube frame. A protective net 9 is arranged around the long fiber packing component.
[0029] Refer to Figure 3 , Figure 4 , for the short fiber bundle packing component, a number of short fiber bundles 21 are loaded inside a cube container to form a packing component. The upper surface 11, the lower surface 41 and the other four surfaces of the cube container are all meshes 9, and the twelve edges of the cube container are a cube frame 31.
[0030] Refer to Figure 5, the long fiber bundle packing component suspends the two ends of several long fiber bundles 2 on the upper support 1 and the lower support 4 respectively. The upper support 1 and the lower support 4 are gratings, and the planar shapes of the upper support 1 and the lower support 4 are square. The upper support 1 and the lower support 4 are installed on the bracket 3 to form a hexahedral packing component. An aeration device 6 and a scrubbing air distribution device 7 are arranged below the lower support 4. The bracket 3 is a cube frame. A cloth 51 surrounds the packing component.
[0031] See Figure 6 , put several clean water modules into the water of the storage tank 60, support them on the bottom of the storage tank 60 through the support frame 8, or suspend them in the storage tank 60 through floating barrels, and connect the air sources of the aeration device 6 and the scrubbing air distribution device 7.
[0032] Working principle: The initial rainwater or the overflow sewage on rainy days enters the storage tank 60 through the water inlet pipe 61. During operation, microorganisms are cultivated on the packing of the clean water module (long fiber bundle 2 packing or short fiber bundle 21 packing). The air is sent into the packing component through the aeration device 6. The water to be treated in the storage tank enters the clean water module from the bottom under the air-lift action and passes through the clean water module from bottom to top. Substances such as organic matter, ammonia nitrogen, nitrate nitrogen, and phosphorus in the water are decomposed and removed by the microorganisms growing on the packing (long fiber bundle 2 packing or short fiber bundle 21 packing) of the clean water module to obtain purification. When the clean water module needs air scrubbing, the scrubbing air enters the lower part of the clean water module through the scrubbing air distribution device 7 and performs air scrubbing on the packing (long fiber bundle 2 or short fiber bundle 21) from bottom to top to peel off the mud on the surface of the packing and the excess biofilm. The water in the storage tank that has been purified to meet the discharge standard is discharged into the nearby river through the water outlet pipe 62.
[0033] See Figure 7 , put several clean water modules partially immersed into the water of the storage tank, support them on the bottom of the storage tank through the support frame 8, or suspend them in the storage tank through floating barrels, and connect the air sources of the aeration device 6 and the scrubbing air distribution device 7. A spray water distribution device 72 is arranged above the clean water module, and the spray water distribution device 72 is connected to a lift pump 71 arranged at the bottom of the storage tank through a pipeline 73.
[0034] Working principle: During operation, microorganisms are cultivated on the packing in the water purification module (long fiber bundle 2 packing or short fiber bundle 21 packing). Air is sent into the water purification module through the aeration device 6. The water in the storage and regulation pool to be treated is sprayed on the packing through the lifting pump 71, pipeline 73 and spray water distribution device 72. The air dissolves in the water along with the spray water flow, and substances such as organic matter, ammonia nitrogen, nitrate nitrogen, and phosphorus in the water are decomposed and removed by the microorganisms growing on the packing (long fiber bundle 2 packing or short fiber bundle 21 packing) in the water purification module to achieve purification. After the water in the storage and regulation pool is purified for a period of time and the water quality reaches the discharge standard to the water body, the drainage pump is started to drain the water in the storage and regulation pool, waiting to receive the initial rainwater of the next rain. When the water purification module needs air scrubbing, the scrubbing air enters the lower part of the water purification module through the scrubbing air distribution device 7 and performs air scrubbing on the packing (long fiber bundle 2 or short fiber bundle 21) from bottom to top to strip the surface mud and excess biofilm on the packing.
