The invention discloses a composite microbial preparation and its use in sewage treatment, belonging to the technical field of microbial preparations. The composite microbial preparation comprises: at least one microorganism, the microorganism contains at least one nitrifying bacteria; and at least one fiber-iron complex. The above-mentioned fibrous iron complex is a fibrous iron (III) complex. The composite microbial preparation of the invention can not only deeply remove COD, BOD 5 , ammonia nitrogen and TP in sewage at a suitable temperature, but also can effectively remove COD, BOD 5 , ammonia nitrogen and TP in sewage under low temperature conditions. The invention also discloses the use of the composite microbial preparation in any one of the following uses: use in sewage denitrification and/or dephosphorization; use in sewage deodorization and/or landfill leachate deodorization; use in increasing sewage transparency Use; use in the preparation of sewage treatment agents. Sewage is industrial sewage, urban sewage, rural sewage, landfill leachate or perishable waste fermented sewage. |
