[0037] In summary, the sewage treatment system for concrete production can preliminarily treat the sewage with silt for concrete production through the filter box 3 which can be moved up and down. During the treatment process, large pieces and part of the silt are filtered out through the filter box 3. After filtering, the filter box 3 is lifted to the highest point to clean the debris inside. The cleaned sewage will be sent to the inside of the silt deep treatment box 7 by the conveying pipe 8.
