Embodiment 1

[0015] Embodiment 1: The preparation method of the biocatalytic composite packing of the present embodiment is as follows: carry out batching according to certain weight percentage, and wherein ultrahigh molecular weight polyethylene is 60%, activated carbon is 32%, iron powder is 5%, manganese powder is 3% ; After uniformly mixing the above ingredients, mold them in a special mold, and bake them in a temperature-programmed furnace at a temperature of 520°C to finally make porous balls with a diameter of 70mm and a density of 0.934g / cm 3 .

[0016] The fluidized bed biocatalytic composite filler prepared by the method of the present invention has been put into use in the sewage treatment project of the acrylic fiber chemical plant of Fushun Petrochemical, and has achieved good results in the treatment of typical refractory acrylic fiber wastewater. The COD of its influent is 260mg / L, effluent COD<50mg / L, reaching the national standard.

Abstract

The invention discloses a process for preparing bio-catalytic combined filling for biological fluidized bed, wherein the fluidized bed biological combination filling comprises (by mass percent) activated charcoal 30-35%, super macromolecular polyethylene 56-64%, iron 4-6%, manganese 2-3%. The filling is prepared through compression molding and sintering, wherein the sintering temperature being 500-560 deg. C.

Description

technical field [0001] The invention relates to a preparation method of a novel biocatalyzed composite filler for a biological fluidized bed in a sewage treatment process, and belongs to the technical field of a biological fluidized bed process for wastewater treatment. Background technique [0002] The fluidized bed biological treatment of wastewater is developed after the fluidized bed technology is widely used in the chemical industry. Biological fluidized bed technology is to make the matrix in the wastewater contact with the fluidized and uniformly dispersed biofilm in the bed to degrade and remove it, and the biofilm phase grows and fixes on the carrier of a certain composition and shape. The research and application of biological fluidized bed sewage treatment began in the United States in the late 1970s. In the middle and late 1980s, biological fluidized bed treatment of urban sewage and industrial wastewater began to be promoted in engineering. Biological fluidized...
