Abstract

The invention relates to a preparation method of a bioactive filler with biological wax embedded microorganisms, which is characterized by comprising the following steps of: placing a filler in a culture solution for biofilm culturing to generate a filler containing microorganisms; putting biological wax into a container, heating to 100-120 DEG C, adding a modifier, and cooling to 40-50 DEG C at 50-150rap / min to obtain modified biological wax with the melting point of 55-62 DEG C; coating the surface of the filler containing microorganisms with the biological wax modified at 40-50 DEG C with the coating thickness of 0.5-2 mm, and obtaining a bioactive filler after the modified biological wax is cooled and solidified on the surface of the filler containing microorganisms; forming a plurality of small holes in the surface of the bioactive filler so as to ensure the oxygen demand of internal microorganisms; and cutting the bioactive filler into required shapes according to requirements.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a biologically active filler for embedding microorganisms in biological wax, a preparation method and application thereof. Background technique [0002] Sewage treatment is one of the important issues facing environmental protection. With the continuous enhancement of human activities and the development of urban industry, a large amount of sewage is discharged, which has caused serious water pollution of rivers and lakes. At present, in the field of sewage treatment, biochemical treatment methods are widely used, most of which use biofilm technology. [0003] In the wastewater biofilm treatment process, the filled filler is the core part. Filler is the place where biofilm lives and the carrier of biofilm, which affects the growth, reproduction, shedding, shape and spatial structure of microorganisms, and also has the function of intercepting suspended matter. It can be seen that ...
