Abstract

The invention provides a bio-membrane reactor based on a hollow conical activated carbon fiber packing. The bio-membrane reactor comprises a hollow cylindrical reactor, a central supporting axis, a hollow conical magnetic activated carbon filer packing and a packing support; the central supporting axis is positioned on a central axis inside a hollow cylindrical reactor casing and penetrates through the center of the hollow conical magnetic activated carbon filer packing; the packing support is arranged inside the hollow conical magnetic activated carbon filer packing and comprises a plurality of support rods with identical length. According to the bio-membrane reactor provided by the invention, the packing is prepared from activated carbon fibers and is designed into hollow conical shapes, so the problems of poor microbial adhesion property, easiness in entanglement and the like are solved; stables magnetic particles are contained in pores of the hollow conical magnetic activated carbon filer packing, can enhance the activity of microbes in the bio-membrane reactor and enables the capability of the microbes for degrading pollutants to be improved, so that the degradation efficiency of the bio-membrane reactor for the pollutants is improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a biofilm reactor, in particular to a biofilm reactor based on a hollow conical activated carbon fiber filler. Background technique [0002] The filler of the biofilm reactor is the carrier for the attachment and growth of microorganisms, and is the core of the biofilm process. Researchers have made many achievements in the research of biological fillers, and the treatment of sewage with the developed biological fillers has also achieved good pollutant removal effects. These achievements have a great impact on the development of biofilm reactor fillers. However, some fillers still have certain defects. For example, organic carriers represented by polyethylene and polypropylene and inorganic carriers represented by ceramsite often have problems such as poor microbial adhesion, easy clogging and entanglement during use. Based on this, some researchers began to try to use degr...
