MLSS SBRSBR with improved MLSS precipitation efficiency

摘要

The purpose of the present invention is to provide a sequencing batch reactor (SBR) having enhanced precipitation efficiency of mixed liquor suspended solids (MLSS), in which inflowing water flowing into an upper part of a BR reaction tank and falling energy of MLSS are reduced, the MLSS are evenly diffused inward the reaction tank, at the same time, flow rate energy inside the reaction tank is reduced again, the MLSS are evenly diffused over the whole cross section of the reaction tank, and high concentration of MLSS are discharged after being efficiently precipitated on the bottom surface by enhancing bio-coherence. To this end, the SBR having enhanced precipitation efficiency of MLSS comprises: the BR reaction tank; a refining means; a plurality of diffusion means; an overlapping means; a discharge unit for each; a perforated pipe for each; a plurality of parallel sludge scrapers; a drawing means; an MLSS supply unit; and a discharge means. Accordingly, precipitation efficiency in the SBR reaction tank can be maximized, thereby providing excellent drawing efficiency and, in particular, maximizing reaction efficiency in a bio-reaction tank.
