Abstract

The invention discloses a preparation method of immobilized microbial filler, and belongs to the technical field of sewage treatment. The preparation method comprises the following steps: first, sodium alginate and polyvinyl alcohol are dissolved in water to prepare a sodium alginate-polyvinyl alcohol solution; then a microbial bacteria solution and zeolite are mixed evenly and then added into thesodium alginate-polyvinyl alcohol solution, full stirring and even mixing are conducted, and thus a sodium alginate-polyvinyl alcohol mixed solution containing microorganisms is obtained; and then biological filler is soaked in a mixed solution containing the microorganisms to enable the surface of the filler to be evenly covered with the mixed solution containing the microorganisms, and then thefiller is taken out, finally soaked in a boric acid-calcium chloride aqueous solution for 12-24 h, washed by normal saline and air-dried, and thus the microbial filler is obtained. The preparation method is easy to operate, the problem that the natural biofilm culturing time of the biological filler in a water body is long is effectively solved, and the degradation efficiency of the biological filler to pollutants is improved.

Description

technical field [0001] The invention relates to a preparation method of filler, in particular to a preparation method of immobilized microbial filler, which belongs to the technical field of sewage treatment. Background technique [0002] Immobilized microorganism technology is to immobilize microorganisms in the carrier by means of adsorption, cross-linking or embedding, so that it has a higher concentration of biomass and biological activity in the reaction area, and at the same time it is beneficial for microorganisms to resist unfavorable environments, thereby improving the microbial life. Reaction efficiency, shorten reaction time, this technology is widely used in medicine, food, chemical industry and other fields. At present, in the field of water body treatment, the particles immobilized with microorganisms are usually directly splashed into the river for use. Using this method, the microorganisms are easy to sink into the river bottom, thereby greatly reducing the t...
