[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A vertical flow sewage filtration treatment device, such as Figure 1 , Figure 2 As shown, the sewage filtration treatment device adopts a vertical flow filtration structure, which includes an integrated box body. A sedimentation area is arranged in the integrated box body. A water inlet pipe is fixedly arranged above the sedimentation area. The water inlet pipe is used to supply waste sewage. Below the sedimentation area is a sludge settling area. The bottom of the sludge settling area is a conical structure, which is used to accumulate and collect sludge in the sewage.

[0023] A sludge discharge pipe is fixedly provided at the bottom of the sludge settling area to discharge the sludge at the bottom of the sludge settling area. A water collection channel is provided on the outside of the sedimentation area. A partition is provided between the water collection channel and the sedimentation area. The upper clear liquid in the sedimentation area flows over the partition and enters the water collection channel. A filtration area is provided on the outside of the sedimentation area.

[0024] In this embodiment, the filtration area is arranged in a ring shape, and the ring array of the filtration area is arranged outside the sedimentation area.

[0025] A water receiving channel corresponding to the water collecting channel is fixed on the top of the filtration area. The water receiving channel and the water collecting channel are connected by a siphon. The water in the water collecting channel is sucked into the water receiving channel by the siphon principle. When the water in the channel is full, it will overflow into the filtration area.

[0026] A backwash collection channel is fixedly provided on the outside of the filtration area, and a backwash drainage channel is fixedly provided on the outside of the filtration area. A siphon is also connected between the backwash collection channel and the backwash drainage channel to pump the flushing wastewater in the backwash collection channel into the backwash drainage channel and discharge the flushing water.

[0027] A packing layer is fixedly provided in the filtration area, and the packing layer is used to filter impurities in the wastewater. The packing layer includes one or more of activated carbon, quartz sand, gravel, fiber balls, fruit shell filter materials, and foam filter beads. A water collection area is fixedly provided below the filtration area, and the water collection area is used to collect clean water filtered by the packing layer. A water outlet is fixedly connected to the outside of the water collection area for discharging filtered water, and a water inlet is fixedly connected to one side of the water outlet for supplying backwash water to the water collection area.

[0028] The backwash water is supplied from the water collection area, passes through the packing layer, and cleans the filter area. Then the cleaning wastewater overflows from the filter area into the backwash water collection channel. The backwash water is sucked into the backwash drainage channel through the siphon to drain the cleaning wastewater.

[0029] Each siphon tube is connected to the same vacuum system, and the operation of the siphon tube is controlled by the vacuum system.

[0030] Here’s how it works:

[0031] In this embodiment, the water inlet pipe is arranged at the center of the sedimentation area, and a splash plate is connected to the water inlet pipe, and water is evenly distributed to the pool body through the splash plate;

[0032] In this embodiment, the sewage is physically precipitated in the sedimentation area, and the supernatant is collected by the sump, and then the water is transported to the filtration area outside the sedimentation area through the siphon pipe for treatment. The precipitated particles and sludge are discharged to the subsequent sludge treatment process through the sludge discharge pipe of the sedimentation area.

[0033] The filtration area collects water through the sump, and the overflow transports raw water to the filtration area. The raw water is filtered through the filter layer, reaches the water collection area located at the bottom of the filter layer, and is sent to the water use point through a pipeline.

[0034] During backwashing, the incoming water enters the water collection area, passes through the filter head, and backwashes the filter material in the filter layer. The backwash water flows through the backwash drain trough and siphon into the backwash drain area and is discharged through the pipe.
