Abstract

The invention discloses a biofilm carrier as well as a reaction system and application thereof. The biofilm carrier comprises a plastic casing and polyurethane sponge; the plastic casing is provided with a plurality of penetrating alternating holes; and the polyurethane sponge is fixed in the alternating holes. The biofilm carrier adopts a plastic and sponge combined way, so that the density of the carrier is closer to the density of water, the defect that after traditional polyurethane sponge is enriched with microorganisms, the traditional polyurethane sponge is easily deposited at the bottom of a reactor at low aeration rate is avoided, and the carrier can move more sufficiently in the reactor, so that the mass transfer effect is good, and the adsorption and the degradation of the microorganisms to pollutants are facilitated.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to the technical field of biological treatment of wastewater (sewage), in particular to a biofilm carrier and its reaction system and application. Background technique [0002] Sulfonamides (SAs) refer to a class of drugs with p-aminobenzenesulfonamide structure; among them, sulfonamide antibiotics are synthetic high-efficiency broad-spectrum antibacterial drugs, which are widely used in agriculture, aquaculture, animal husbandry and human disease treatment Among them, it is the first class of chemotherapeutic drugs used for the prevention and treatment of bacterial infections in humans. According to the survey of the World Health Organization, the utilization rate of antibiotics in hospitalized patients in my country is as high as 80%, far higher than the international level of 30%, and sulfonamide antibiotics are also widely used in animal husbandry in my country. Af...
