Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a denitrification biological rapid filter. Background Art

[0002] A denitrifying biological rapid filter is a wastewater treatment facility. Its working principle is as follows: Denitrifying biological rapid filters primarily utilize microorganisms attached to filter media to perform denitrification. In an oxygen-deficient environment, denitrifying bacteria use organic matter as electron donors to reduce nitrate and nitrite nitrogen in wastewater to nitrogen gas, thereby achieving denitrification. Wastewater treatment refers to the process of purifying wastewater containing pollutants through a series of treatment processes to meet environmental discharge standards or reuse requirements. Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life. The primary goal of wastewater treatment is to ensure that wastewater meets water quality requirements for discharge into a water body or reuse. Physical, chemical, and biological methods are used to remove pollutants from the water, including organic matter, pathogenic pollutants, and plant nutrients. With the development of society, rapid filters are used when wastewater needs to be treated.

[0004] When workers need to treat wastewater, they input the wastewater into the rapid filter tank so that the rapid filter tank can treat the wastewater. However, the newly input wastewater will carry a large amount of floating objects, and too many floating objects will cause the pipes and grilles to be blocked, resulting in a reduction in the water supply capacity of the rapid filter tank, which in turn leads to a reduction in the filtration efficiency of the rapid filter tank.
