Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and more specifically to a biological activated carbon adsorption device in the process of wastewater treatment. Background Art

[0002] The biological activated carbon method is a wastewater biological treatment process that uses activated carbon as a carrier to form a biofilm on the carbon surface during the wastewater treatment process, resulting in a synergistic effect of activated carbon adsorption and microbial oxidation and decomposition of organic matter. This method significantly improves the removal rate of organic matter in wastewater. The adsorption of activated carbon provides abundant attachment space and nutrient sources for microorganisms, while the metabolic activities of microorganisms further promote the degradation of organic matter. The synergistic effect of the two enables more efficient removal of organic matter in wastewater. Due to the adsorption of activated carbon, toxic substances in wastewater can be adsorbed, reducing the burden on microorganisms.

[0003] In the prior art, biochar is mostly installed inside a sewage discharge pipe during installation. The sewage passes through the biochar during its flow to filter the sewage. However, when the biochar needs to be replaced due to weakened use effect or saturation, it is deeply hidden inside the pipe, making the replacement operation extremely complicated and difficult, greatly increasing the difficulty and cost of maintenance work. For this reason, we propose a biological activated carbon adsorption device for wastewater treatment. Utility Model Content
