Problems solved by technology

Although the current biological filter material can be used for sewage treatment, there are also problems such as high preparation temperature, hard shells on the surface of the filter material, which are not conducive to the growth of microorganisms, or poor biocompatibility, poor sewage decolorization effect, or specific surface area. Disadvantages such as small size, low porosity, and short service life

Abstract

The invention discloses a composite biological filter material comprising neodymium ferrite nanowires and belongs to the technical field of biological sewage treatment. The composite biological filter material comprising the neodymium ferrite nanowires comprises components in percentage by mass as follows: 40%-50% of the neodymium ferrite nanowires, 6%-15% of polymethylmethacrylate, 5%-9% of polyethylene glycol, 1%-5% of polyvinylpyrrolidone, 8%-16% of clay and 25%-35% of water. The spherical biological filter material with the rough surface is prepared from the neodymium ferrite nanowires used as a main raw material, has the characteristics of large specific surface area, high porosity, high adsorption capacity, good chemical and thermal stability, high sewage decoloration and degradation capacity, capability of facilitating formation and growth of biological films and the like, and has the good application prospect in the technical field of biological sewage treatment.

Description

Technical field [0001] The invention belongs to the technical field of sewage biological treatment, and specifically relates to a neodymium ferrite nanowire composite biological filter material for sewage treatment. Background technique [0002] The biological aerated filter is an important equipment for sewage treatment, and the biological filter is the key material of the biological aerated filter, which determines the decontamination efficiency of the biological aerated filter. In the process of use, the biological filter material forms a biofilm in the filter tank, which can filter the suspended solid pollutants in the water. The organic pollutants in the sewage are degraded by the aerobic metabolism of microorganisms on the surface of the filter material, so the biological filter material is sewage treatment One of the important research content. [0003] Inorganic biological filter material is a commonly used biological filter material, and a variety of inorganic biological ...
