Description

Technical Field

[0001] The utility model relates to the technical field of bottom filter bricks, in particular to a bottom filter brick structure of a denitrifying deep bed filter tank. Background Technique

[0002] Denitrification, also known as nitrogen removal, refers to the biochemical process in which bacteria reduce the nitrogen in nitrate to nitrogen gas through a series of intermediate products. The bacteria participating in this process are collectively called denitrifying bacteria. Under anaerobic conditions, denitrifying bacteria use nitrate as an electron acceptor to complete respiration to obtain energy. Denitrification is often used in the treatment and purification of ammonia nitrogen in sewage.

[0003] In related technologies, through retrieval, a solution of a deep bed denitrifying filter tank (publication number: CN206666221U) is found. When in use, quartz sand is used as the membrane medium for denitrifying microorganisms. The filter tank can ensure that the effluent SS is lower than 5mg / L, and the sewage purification effect is good. Using a sand layer as the solid filter material, its high-load characteristic greatly extends the filtration cycle and reduces the number of backwashes. The filter tank uses air-water combination for backwashing, with good backwashing effect, and the backwash water can be recycled to save resources. During the denitrification process, since nitrate nitrogen is continuously reduced to nitrogen gas, a large amount of nitrogen gas will accumulate in the filter tank. The nitrogen gas will cause the sewage to bypass between the media, which enhances the contact between microorganisms and water and further improves the purification efficiency.

[0004] In the above, the filter brick layer and the filter material layer are used to filter sewage, and the filter material layer is placed on the top of the filter brick layer. However, the filter material layer in the above is not fixed. Therefore, when filtering sewage, the sewage may wash away the materials inside the filter material layer, resulting in the sewage being unable to be filtered from the surface of the filter material layer, which is very inconvenient to use. In view of this, we introduce a bottom filter brick structure of a denitrifying deep bed filter tank. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bottom filter brick structure of a denitrifying deep bed filter tank to solve the problems raised in the above background technique.

[0009] The base surface water seepage layer is arranged inside the filter brick and above the filter layer. The setting of the base surface water seepage layer can filter sewage. A fixing mechanism is arranged inside the base surface water seepage layer. The rotating disc of the fixing mechanism drives the rotating column and the fixing block to rotate, so that the fixing block rotates into the filter brick to form a fixation.

[0010] Preferably, the fixing mechanism includes a positioning rod connected to the bottom of the rotating disc. The positioning rod is fixedly arranged with the rotating disc.

The bottom of the rotating column extends to the outside of the positioning block. The fixing block is connected to one side of the rotating column. The fixing block is fixedly arranged with the rotating column. A fixing groove for inserting the fixing block is formed in the inner side wall of the filter brick. The fixing groove is integrally formed with the filter brick. After the fixing block is inserted into the fixing groove, fixation can be achieved.

[0011] Preferably, honeycomb openings are equidistantly arranged on the surface of the honeycomb reinforcement layer. A sponge block is connected inside the honeycomb opening. The size of the sponge block is the same as that of the honeycomb opening. Thus, the sponge block can be replaced. The setting of the sponge block can filter sewage.

Finally, the base surface water seepage layer is installed on the top of the sand filter layer and inside the filter brick. The rotating disc is used to drive the positioning rod, the rotating column and the fixing block to rotate, so that the fixing block rotates from one side at the bottom of the base surface water seepage layer to the other side, and the fixing block rotates into the fixing groove inside the filter brick, thereby completing the fixation of the base surface water seepage layer, and further completing the installation and fixation of the honeycomb reinforcement layer, the filter layer and the base surface water seepage layer, and thus facilitating the use;

[0014] By using the combined use of the base water seepage layer, sand filtration layer, filtration layer, honeycomb reinforcement layer, sponge block and filter brick, the sewage inside the denitrifying deep bed filter can be filtered, so that the sewage can be filtered more cleanly. At the same time, when the base water seepage layer, sand filtration layer, filtration layer, honeycomb reinforcement layer and sponge block cannot filter, reverse the operation of the turntable, which can drive the fixed block to disengage from the fixed slot, and then replace the base water seepage layer, sand filtration layer, filtration layer, honeycomb reinforcement layer and sponge block, making it more convenient to use.
