The utility model provides movable integrated equipment for recycling domestic sewage in a highway construction period. The sewage treatment system consists of a septic tank, a grating well, a regulating tank, an anoxic tank, a contact oxidation tank, a sedimentation tank, a middle water tank, a double-medium filtering device, a disinfection tank, a control cabinet, a clean water tank, a toilet and a container shell, construction personnel at a highway construction site generate domestic sewage in a toilet of the integrated equipment; drainage into septic tank through sewer pipe, carrying outpreliminary precipitation and decomposition treatment; sewage flowing through grid well, intercepting solid matter, the sewage enters the regulating tank, is subjected to secondary biochemical treatment through the anoxic tank and the contact oxidation tank to realize removal of pollutants such as organic matters and ammonia nitrogen, then flows into the sedimentation tank to be clarified throughsedimentation, is treated through advanced treatment links such as filtration and disinfection, is discharged into the clean water tank and is recycled for flushing toilets, so that water resources are recycled, and the sewage is prevented from being discharged. The sewage treatment system is integrated in the container, so that convenient transportation can be realized.
