Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mixed activated carbon circulation device for sewage treatment. Background Art

[0002] In sewage treatment, after the primary treatment, the sewage needs to be treated by a mechanical sand filter for secondary treatment to improve the water quality. Because the mechanical sand filter can effectively remove suspended matter, organic matter, colloids, silt, etc. in the water, sand filters are widely used in water treatment. The filter materials used in the mechanical sand filter are usually: activated carbon, quartz sand, manganese sand, etc. in granular form. Because the filter material is small in size, it is generally scattered in the filter cap in the filter. The filter material often flows due to the impact of the water flow and causes loss. In the process of use, due to the adsorption of the filter material, it is usually necessary to replace the new filter material after a period of use to avoid secondary pollution of the filtered water quality. The replaced filter material is often buried after being judged to have no adsorption according to human experience, resulting in a waste of resources. In order to solve the above problems, we propose a mixed activated carbon circulation device for sewage treatment. Summary of the invention
