Abstract

A preparation method of embedding immobilized effective microorganism gel pellets relates to a microbial cell immobilization method for saprobe denitrification, specifically to a method taking polyvinyl alcohol and sodium alginate as the embedding agent, calcium chloride and boric acid as a cross linker and shell powder as additives to embed the effective microorganism. The invention provides a preparation method of embedding immobilized effective microorganism gel pellets which can not only effectively resolve the defects in the preparation and use process of the gel pellet, but also can effectively improve the biological denitrification effect by taking the effective microorganism as embedding thalli. The method includes: mixing uniformly the embedded agents and additives, dissolving in water, completely dissolving and mixing uniformly and then cooling to below 40 DEG C, mixing with the centrifuged effective microorganism concentrated bacterium liquor, stirring, and then adding into the cross-linker to form the gel pellets.

Description

technical field

[0001] The invention relates to a microbial cell immobilization method for biological denitrification of sewage, in particular to a method using polyvinyl alcohol and sodium alginate as embedding agents, calcium chloride and boric acid as crosslinking agents, and shell powder as embedding agents. Additives, the method of embedding effective microorganisms (Effective Microorganisms, referred to as EM). Background technique

[0002] Microbe embedding and immobilization technology is a relatively new technology in the field of wastewater biological treatment. It encloses microorganisms in natural polymer polysaccharides or synthetic polymer gels, thereby immobilizing microorganisms. Compared with the ordinary activated sludge method, the embedding and immobilization technology has the following advantages: preventing microbial loss, high microbial concentration in the reactor, anti-toxin and impact load, good settling performance, and conducive to solid-liquid s...
