Example Embodiment

[0027] Example: as attached figure 1 , 2 , 3, 4, and 5, an MBBR high-standard sewage treatment system includes a filter tank, an anaerobic tank, an anoxic tank, an aerobic tank, and a sedimentation tank in turn, characterized in that: the sludge is discharged below the sedimentation tank A sludge return pipe is arranged between the inlet and the water inlet of the anaerobic tank, and the sludge return pipe is provided with a pipe body closing unit for adjusting the sludge flow rate.

[0028] The pipe body closing unit includes a mounting plate 1, a closing slot 2 provided on the mounting plate 1, which is provided on the two side walls of the closing slot 2 and used for the sludge return pipe The pipe holes 3 passing through are respectively provided on the two mounting posts 4 at the positions on both sides of the inner bottom surface of the closing slot 2, and both ends are slotted and clamped on the two mounting posts 4 and used The closing plate unit 5 for pressing and closing t

Abstract

The invention belongs to the technical field of sewage disposal and particularly relates to an MBBR high-standard sewage disposal system and process. The effect of flexible and controllable outward reflux of sludge in an MBBR process is achieved by arranging a pipe body closing unit comprising a mounting plate, a groove for closing, a pipe hole, mounting columns, a closing plate unit, a magnetic attraction unit and a jacking column unit on a sludge reflux pipe. The system has the advantages that an outward reflux adjusting and controlling structure for sludge from a sedimentation tank to an anaerobic tank is reasonable and effective, the opening and closing operation of the pipe body closing unit is simple and convenient, the closing and clamping amplitude is great during step-by-step clamping adjustment of the magnetic attraction unit and stepless clamping adjustment of the jacking column unit, a good outward reflux effect of sludge is achieved, and the sewage disposal effect of the overall MBBR process is great so that the requirement for quasi-IV water on the ground surface can be met after sewage disposal.
