Description

Technical Field

[0001] The utility model belongs to the field of sewage denitrification and denitrification, and particularly relates to a sewage denitrification and denitrification device. Background Art

[0002] Nitrogen-containing wastewater discharged during industrial production, nitrogen fertilizers applied in agriculture are washed into rivers and lakes with rainwater, and domestic sewage discharged into water bodies can cause increasingly serious pollution to the environment, which has attracted widespread attention. Denitrification is also called denitrification. This process refers to the biochemical process in which bacteria reduce nitrogen in nitrates to nitrogen gas through a series of intermediates. Under aerobic conditions, nitrifying bacteria in sewage are used to convert nitrogen-containing substances into nitrates, and then under anaerobic conditions, denitrifying bacteria in sewage are used to reduce nitrates to gaseous nitrogen. Through this process, the effect of sewage purification can be achieved.

[0003] According to a Chinese patent with the announcement number "CN216890311U", a new denitrification and denitrification device is disclosed, including a sewage pool, an aeration component is fixedly connected to the outer side of the sewage pool, an arc-shaped installation groove is opened on the inner bottom surface of the sewage pool, the output end of the aeration component penetrates the inner wall surface of the sewage pool and is fixedly connected to the arc-shaped installation groove opened in the sewage pool, the inner wall surface of the sewage pool is fixedly connected to the separation component, the upper end surface of the sewage pool is fixedly connected to the delivery component, the aeration component includes an air pump, the air pump is fixedly connected to the outer side surface of the sewage pool, the output end of the air pump is fixedly connected to the aeration pipes evenly distributed, and the outer side surface of the aeration pipe is opened with evenly distributed release holes. The new denitrification and denitrification device solves the problem that the denitrification bacteria and sewage of the traditional denitrification and denitrification device cannot be quickly and fully integrated, and the new denitrification and denitrification device solves the problem that the traditional denitrification and denitrification device does not have a liquid and solid separation device to facilitate water extraction;

[0004] It can be seen from the above structure that the utility model is provided with an aeration component and a separation component. When the new denitrification and denitrification device is working, the sewage is put into the interior of the sewage pool, and then the air pump releases oxygen from the release hole through the aeration pipe to aerate the sewage. After the sewage is aerated and precipitated, the first motor drives the screw to rotate, and the rotation of the screw drives the separation filter plate to move downward in the sewage pool. The separation filter plate moves downward to squeeze the precipitated solids on the bottom layer, and then the upper water body can be extracted. This structure solves the problem that the traditional denitrification and denitrification device does not have a liquid and solid separation device to facilitate the extraction of water. According to the above structure, it can be seen that the impurities in the sewage are mainly filtered through the aeration component and the separation component, and the filtering through the above aeration component and the separation component makes the filtering effect poor, and the impurities filtered out cannot be conveniently discharged, thereby reducing the practicality of the device, and the above sewage denitrification and denitrification device has a poor denitrification reaction effect on the sewage, affecting the sewage treatment effect.
