This type of device mainly converts nitrate nitrogen and organic nitrogen in wastewater into harmless nitrogen gas through biological treatment methods, thereby achieving the purpose of purifying water quality. High-nitrogen wastewater will cause eutrophication of water bodies, promote excessive reproduction of algae in the water, and cause ecological and environmental problems such as hypoxia in water bodies and fish deaths. By removing total nitrogen from wastewater, the occurrence of eutrophication of water bodies can be effectively prevented and the ecological environment can be protected.

[0003] The pre-filter device of the existing total nitrogen removal device for wastewater treatment was not designed to fully consider the problem of filter blockage during long-term operation.

In addition, when replacing the filter material, the operating process is unreasonable.

[0004] Therefore, it is necessary to invent a total nitrogen removal device for wastewater treatment to solve the above problems. Utility Model Content

[0031] The total nitrogen removal device for wastewater treatment provided by the utility model works as follows when in use:

[0032] First, install the base 1 at the desired position, and then fix the treatment box 2 on the upper end of the base 1. According to the source of the wastewater, connect the No. 1 water inlet 3 and the No. 2 water inlet 31 to the corresponding wastewater source. Next, install the No. 1 filter box 4 and the No. 2 filter box 41 on the lower front side of the base 1, corresponding to the No. 1 water inlet 3 and the No. 2 water inlet 31, and then the wastewater is transported to the No. 1 water inlet 3 and the No. 2 water inlet 31 through the two front ends of the delivery pipe 10 through the two connecting pipes 6, and the wastewater passing through the two connecting pipes 6 is filtered again through the No. 1 filter box 4 and the No. 2 filter box 41. During the filtration process, the particulate matter is intercepted by the filter screen, and the filtered clean water enters the treatment box 2 for the next step of treatment.

[0033] After these particles are intercepted by the filter, they will remain in the sedimentation pipe 8 below the connecting pipe 6. Therefore, the foreign particles in the sedimentation pipe 8 of the two connecting pipes 6 can be cleaned regularly.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
