Description

Technical Field

[0001] The utility model relates to the technical field of denitrification filter tanks, in particular to an integrated carbon source dosing device for a denitrification filter tank process. Background Art

[0002] As the country's attention to water pollution continues to increase, sewage treatment plant discharge standards have gradually been raised to the Class A standard in the "Pollutant Discharge Standards for Urban Wastewater Treatment Plants." Since my country's urban sewage generally has a low carbon-nitrogen ratio, to control the total nitrogen content in the effluent to meet the standard, and considering factors such as the investment, progress, and effectiveness of the upgrade, the post-deep bed denitrification filter process is widely used in Class A upgrades. The operation of deep bed denitrification filters primarily relies on an external carbon source to control the denitrification reaction and ensure that the total nitrogen content in the effluent meets the standard. The activity of the biofilm within the denitrification filter is the core factor in the denitrification reaction, and this activity requires an external carbon source to maintain.

[0003] The Chinese patent (authorization announcement number: CN 217709019 U, authorization announcement date: 2022.11.01) proposes a denitrification filter carbon source dosing device. By setting up a stirring component, the component can improve the mixing efficiency of the carbon source and water, so that the carbon source solution and the water body are mixed more evenly. At the same time, by installing a scraper at the lower end of the first stirring rod, the solid carbon source deposited at the bottom of the dissolution tank can be stirred to prevent the problem of incomplete dissolution of the solid carbon source.

[0004] When the above device is in use, the cleaning component can only drive the second stirring rod to rotate, and the second stirring rod cannot rotate around the inner wall of the dissolution box for cleaning. In addition, the carbon source dosing device of the denitrification filter is not uniform when adding the carbon source, which easily affects the reaction rate of denitrification. In order to solve the problem of thorough cleaning of the inner wall of the dissolution box and improve the uniformity of the carbon source addition of the device, we propose an integrated carbon source dosing device for the denitrification filter process.
