Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biofilm reactors and relates to a biofilm reactor equipped with a high aeration structure. Background Art
[0002] Existing biofilm reactors have several drawbacks when it comes to increasing aeration rates unless they can disrupt the wastewater flow. Because biofilm reactors rely on gas-liquid contact to provide oxygen, failure to effectively disrupt the flow reduces oxygen transfer efficiency, impacting microbial metabolic activity and pollutant removal efficiency. Lack of effective disruption can slow biofilm surface renewal, leading to excessively thick biofilms, impacting the hydrodynamics within the reactor, potentially causing the formation of dead zones and reducing treatment efficiency.
[0003] The main reasons for these shortcomings are the limited oxygen transfer caused by insufficient aeration, and the lack of sufficient turbulence makes it impossible for the biofilm to renew and grow evenly. Conventional coping methods include increasing the amount of oxygen, regularly cleaning or replacing the biofilm, etc. However, these methods also have disadvantages. For example, increasing the amount of oxygen will increase energy consumption and increase operating costs; regularly cleaning or replacing the biofilm will increase the complexity and labor intensity of the operation, and will also cause discontinuity in the operation of the system, affecting the stability of the treatment effect. Therefore, there is an urgent need for a biofilm reactor equipped with a high aeration structure to solve the above problems. Utility Model Content
