Matrices for fats degradation and a FOG trap apparatus equipped with the matrices

摘要

PURPOSE: Provided are a matrix for degrading FOG (Fats, Oil and Grease) and reducing COD, the matrix being applicable to domestic wastewater, and a FOG trap using the same. CONSTITUTION: The matrix comprises a base made of ceramic, polyurethane or rice bran and pseudomonas D2D3 strains (KCTC 10056BP) immobilized on to the base. The FOG trap comprises three stage-treatment sections(1,2,3) which are defined by compartments(14,22) with a plurality of perforated holes, wherein a first stage of treatment section(1) has a wastewater inlet(13) at a side thereof, a barrier(12) connected to the inlet(13) and installed at the center thereof, a first matrix box(12) having the matrix therein, onto which pseudomonas D2D3 strains are immobilized and being installed above the surface of wastewater, and a diffuser(4) installed at the bottom thereof for blowing the wastewater upward, wherein a second stage of treatment section(2) has a diffuser(4) for blowing the wastewater upward and a second matrix box(21) having the bottom abutted to the surface of the wastewater and having the matrix therein, onto which the pseudomonas D2D3 strains are immobilized, and wherein a third stage of treatment section has a diffuser(4) for blowing the wastewater upward and a third matrix box with the pseudomonas D2D3 strains therein, completely dipped into the wastewater.
