Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a high-efficiency carbon source dosing device for municipal wastewater treatment plants. Background Technology

[0002] In wastewater treatment systems, microorganisms are the primary biological group responsible for treating wastewater. Microorganisms require carbon sources to sustain their life activities and growth. If the wastewater lacks sufficient organic matter as a carbon source, microbial growth will be limited, affecting the efficiency of the entire treatment system. In such cases, it is necessary to artificially add organic matter as a carbon source. Furthermore, nitrification and denitrification are crucial steps in nitrogen removal. Nitrification converts ammonia nitrogen into nitrate, while denitrification reduces nitrate to nitrogen gas, thus reducing the nitrogen content in the water. Nitrifying bacteria are autotrophic bacteria that primarily utilize inorganic carbon sources (such as CO2 and HCO3-), while denitrifying bacteria require organic carbon sources (such as ethanol and methanol) to provide electron donors to complete the denitrification process.

[0003] Currently, in municipal wastewater treatment, carbon source dosing devices generally suffer from problems such as uneven mixing of reagents, inability to dynamically adjust the dosage in real time, and insufficient spray coverage area. This results in low denitrification efficiency and serious waste of reagents. Traditional devices often rely on manual experience to adjust the dosage, which is difficult to adapt to fluctuations in the total nitrogen concentration of the influent. This can lead to insufficient carbon source dosing causing excessive total nitrogen in the effluent, or excessive dosing causing secondary pollution. Utility Model Content

[0014] As a further optimization scheme of the utility model, one end of the metering pump is connected with the rotating joint, the other end of the metering pump extends into the storage bin, and an overflow partition plate is arranged between the storage bin and the stirring bin.
