Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Example 1

[0018] like Figures 1-3 As shown, a packing assembly includes a base 1 and a packing unit 3. The base 1 has a corresponding supporting force, and a support rod 2 is mounted on the base 1. Multiple packing units 3 are arranged vertically and intermittently on the support rod 2, and a passage for water to pass through is formed between the upper and lower packing units 3, so that the water can fully contact and react with the packing inside the packing unit 3.

[0019] The packing unit 3 includes a shell 4, which forms an internal receiving chamber. An installation pipe 5 is provided in the middle of the receiving chamber. The support rod 2 can move through the installation pipe 5 and has corresponding sliding damping between it and the inner wall of the installation pipe 5. The upper and lower ends of the shell 4 are open and are respectively equipped with an upper cover 8 and a lower cover 9. The upper cover 8 and the lower cover 9 can open the upper and lower ends of the shell 4 to facilitate the opening of the activated sludge (e.g., denitrification sludge). The support rod 2 is inserted into the installation pipe 5 and extends out of the installation pipe 5, so that the corresponding shell 4 is assembled on the support rod 2. The specific position fixing and installation method are existing technologies and will not be described in detail here.

[0020] The upper cover 8 and the lower cover 9 are respectively opened with outlet 7 and inlet 6. Inlet 6 and outlet 7 are staggered. When multiple shells 4 are arranged vertically, and adjacent shells 4 are arranged vertically, sewage enters from the inlet of shell 4 in sequence and is discharged from the outlet. After passing through multiple shells 4, it reacts with activated sludge, extending the contact path between sewage and activated sludge, so that sewage is discharged from the packing area along a predetermined path. Example 2

[0021] Based on the above embodiments, such as Figures 1-4As shown, the present application also proposes a denitrification reactor, which comprises a shell 10, the packing unit 3 proposed in the above embodiments and an internal circulation unit; the shell 10 has a corresponding accommodation space inside, and a water inlet pipe 11 and a water outlet pipe 12 are connected to the corresponding positions of the lower part and the upper part of the side wall, respectively; an upper cover 13 is arranged at the top end; the water inlet pipe 11 is arranged at the lower part of the side wall of the shell 10 and is connected to a water distribution system to inject sewage into the reactor from the lower part; and the water outlet pipe 12 is arranged at the upper part of the side wall of the shell 10 to discharge the treated sewage. The denitrification reactor is also provided with three separators and other necessary functional components of the denitrification reactor, which are prior art and will not be described herein.

[0022] The packing unit 3 is erected in the shell 10 through the support rod 2 on the base 1, the shell 4 of the packing unit 3 is filled with activated sludge, and a plurality of packing units 3 are arranged in layers to form a plurality of packing layers. When the sewage passes through, it enters the packing unit 3 from the inlet 6 of the shell 4 of the packing unit 3, fully contacts and reacts with the sludge, and is discharged from the outlet 7 of the shell 4 of the packing unit 3. The sewage sequentially passes through a plurality of inlets 6 and outlets 7 to pass through the packing layers from a specific path. In this process, the contact path of the sewage and the activated sludge is prolonged, so that the sewage and the activated sludge are fully contacted.

[0023] In addition, it should be noted that a metal screen with a certain mesh density is arranged at the inlet 6 and the outlet 7. After a reaction stage is completed, the partition (metal screen, water-permeable plate with holes, etc.) can be cleaned (flushed) or replaced to avoid blockage of the inlet 6 and the outlet 7.

[0024] In some preferred embodiments, the packing unit 3 is arranged between the water inlet and the water outlet of the shell 10; the internal circulation unit comprises a pump body 14 arranged outside the shell 10 and water pipes one 15 and two 16 connected to the pump body 14; the water pipes one 15 and two 16 are connected to the liquid inlet end and the liquid outlet end of the pump body 14, respectively; and the water pipes one 15 and two 16 are located above and below the packing unit 3, respectively. After the sewage enters the reactor, the pump body 14 of the internal circulation unit is driven to pump the sewage passing through the packing unit 3 from above the packing unit 3 to below the packing unit 3, so that the sewage is treated again by the packing unit 3 to improve the efficiency of sewage treatment.

[0025] Further, a water distributor 17 is arranged at the lower part of the shell 10. The water distributor 17 is connected to the water inlet pipe 11 and is located below the packing unit 3. Preferably, the water distributor 17 can be located on both sides of the support rod 2. The water distributor 17 distributes water from below the packing unit 3, and the sewage enters the packing layers formed by the packing unit 3 from below.

[0026] It should be noted that when the denitrification reactor is applied to domestication or cultivation of activated sludge, the seed sludge can be inoculated into the shell 4 of the filler unit 3, the sewage enters the filler layer from below through the water distribution system, and passes through a predetermined reaction path, so that the sewage and the seed sludge are in full contact, providing nutrients for the cultivation of bacteria in the seed sludge, increasing the path of the sewage and the seed sludge, and improving the efficiency of the domestication of the seed sludge.

[0027] Specific use is as follows: place the device in a suitable working position, install the filler unit 3, fill the filler unit 3 with fillers such as activated sludge or composite fillers, etc., for contacting sewage and purifying the sewage. The water inlet pipe 11 is connected to the sewage supply system, and the sewage is injected into the reactor from the water inlet pipe 11 below the filler unit 3, and the sewage passes through the filler unit 3 along a specific path and fully contacts the activated sludge, starts the inner circulating unit pump body 14, and makes the water in the upper and lower parts of the filler unit 3 repeatedly pass through the filler unit 3, so that the filler and the sewage are more fully reacted, and the efficiency and effect of the sewage treatment are improved.
