Abstract

The invention discloses a biological diatom water treatment agent, which comprises diatomite, flocculant, activated carbon and water treatment engineering bacteria. The content of flocculant is 20 percent to 50 percent of the mass of diatomite; the content of activated carbon is 1 percent to 5 percent of the mass of diatomite; the content of water treatment engineering bacteria is 0.1 percent to 1 percent of the mass of diatomite. On one hand, the biological diatom water treatment agent of the invention has good absorption ability for the pollutant in the water; on the other hand, the denitrification capability of the immobilized microorganism improves the deficiency of denitrification capability of the diatomite. The invention can also increase the water treatment efficiency; the invention has a compact equipment structure, easy operation and high and stable water quality.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to a diatom (silicon shell) water treatment agent containing microorganisms. Background technique [0002] At present, there are many methods for immobilization of microorganisms, including cross-linking, adsorption, covalent bonding, embedding, etc. The advantages and disadvantages are shown in the table below. [0003] performance cross-linking method Adsorption Covalent Bonding Embedding method Easy to prepare Binding force activity retention fixed cost Viability applicability stability Carrier regeneration Steric hindrance Moderate powerful Low Moderate none Small high cannot larger easy weak high Low Have Moderate Low can Small Disast...
