Abstract
PROVIDED IS A PALM OIL MILL EFFLUENT TREATMENT APPARATUS THAT SUFFICIENTLY REDUCES A BOD COMPONENT AND AN SS COMPONENT OF PALM OIL MILL EFFLUENT. THE PALM OIL MILL EFFLUENT AFTER METHANE FERMENTATION IS INTRODUCED TO AN AERATION TANK 2 FOR BIOLOGICAL TREATMENT. THUS, AN ORGANIC MATTER IS DECOMPOSED SO THAT THE MAINLY SOLUBLE BOD COMPONENT IS REDUCED (BOD COMPONENT HAVING SS CHARACTERISTICS IS REMOVED IN PART AS WELL), AND A FLOCCULANT IS SUPPLIED TO THE BIOLOGICALLY TREATED PALM OIL MILL EFFLUENT FROM THE AERATION TANK 2 BY FLOCCULANT SUPPLY MEANS 10. THE PALM OIL MILL EFFLUENT CONTAINING THE FLOCCULANT AFTER THE SUPPLY OF THE FLOCCULANT IS EASILY SEPARATED INTO TREATED WATER AND FLOCCULATION SLUDGE BY FLOCCULATION SLUDGE TREATMENT MEANS 4, AND, SINCE THE FLOCCULATION SLUDGE IS FORMED WITH THE SS COMPONENT THAT REACTS WITH THE FLOCCULANT, THE SS COMPONENT CAN BE REDUCED IN THE TREATED WATER ALONG WITH THE SS-DERIVED BOD COMPONENT.
Microbial flora activator, anti-filamentous bacteria agent comprising said microbial flora activator as active ingredient, and method for treating waste water containing oil, fat, etc. using said microbial flora activator
