[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] like figure 1 Shown: a system for domestic sewage treatment through a biological filter wall, including a grid pool 1, a sewage collection pool 2, a biological filter wall 3, and a filter pool 4. After the domestic sewage enters the grid pool 1, solid pollutants are filtered out through the grid, and then flows into the sewage collection pool 2, and the treated sewage is deposited and filtered through the sewage collection pool 2, and is sent to the water spray pipe on the biological filter wall 3 through a water pump Inside, the sewage is evenly arranged along the small holes inside the annular water spray pipe, relying on its own gravity, and falls into the biological filter wall 3, after being absorbed by plants and biologically filtered, it falls into the filter pool 4 under the biological filter wall 3, and is filtered The sewage in the pool 4 is...
