Zusammenfassung:The invention relates to the technical field of sewage treatment, and discloses a sewage treatment system and method for separating solid-phase pollutants in sewage, and the method comprises the following steps: S1, introducing the sewage into a filter cartridge for filtering; s2, the filtered sewage is sequentially injected into precipitation cavities below for precipitation, when the sewage enters the corresponding precipitation cavities through mounting pipes, propeller blades are driven to drive rotating ring plates to control opening and closing of discharging assemblies, and chemicals are added into the precipitation cavities; and S3, the sewage injected into the precipitation cavity drives the floating block to block the mounting pipe, then the sewage in the precipitation cavity is subjected to standing precipitation, and finally water is discharged. According to the treatment method, the treatment box can treat the sewage without shutdown, solid-phase pollutants with large particle sizes in the sewage
