| Zusammenfassung: | The invention discloses a full-biological treatment method for high-concentration formaldehyde wastewater, and belongs to the field of biological treatment of high-concentration formaldehyde wastewater, and the treatment method comprises the following steps: firstly, treating the wastewater through a formaldehyde biological pretreatment section, and then carrying out aerobic biological treatment; in the formaldehyde biological pretreatment section, formaldehyde special degrading bacteria are added into a formaldehyde biological pretreatment tank, and the formaldehyde special degrading bacteria are immobilized on a polyurethane filler for aerobic aeration treatment; in the aerobic biological treatment, 0.1% of aerobic compound bacteria and 70% of polyurethane filler are inoculated in an aerobic reaction tank. The method for treating the high-concentration formaldehyde wastewater by combining efficient formaldehyde exclusive microorganisms and bioactive filler becomes a main solution for biological treatment of |
