Embodiment 1

[0014] Example 1: Test of the influence of antagonistic bacteria and dispersants on the formation of deposits

[0015] Experimental procedure

[0016] Centrifuge 1mL of each strain isolated from the sludge cultured in NB liquid culture medium for 21-24 hours at 15000rpm for 1min, remove the supernatant, add 1mL of sterile water to resuspend all the test strains, and then inoculate into 100mL Erlenmeyer flask with sterilized white water and 3g LBKP slurry. Afterwards, different dispersants were added to the above treatment respectively, and cultured in a 40°C, 70rpm shaking incubator. After 3hrs of fully mixed culture, 3mL of the antagonistic bacteria C5 Streptomyces bikiniensis (Streptomyces bikiniensis) that had been cultured for 24h were added. Bacterial liquid, about 107 / ml, and cultured in 40°C, 70rpm shaking incubator, observed and recorded the amount of precipitation after 7 days.

[0017] The whole experiment was divided into six treatments,

[0018] There are two c...

Embodiment 2

[0048] Embodiment two: Follow-up test of regular addition of antagonistic antibiotics

[0049] Experimental procedure

[0050]Centrifuge 1 mL of each strain isolated from the sludge cultured in NB liquid culture medium for 21-24 hours at 15,000 rpm for 1 min, remove the supernatant, add 1 mL of sterile water to resuspend all the test strains, and then inoculate into 100 mL of the sterilized Bacterial white water and 3g LBKP slurry in the conical flask, mix well and culture in 40°C, 70rpm shaking incubator, after 3hr, add 3mL of antagonistic bacteria C5 cultured for 24h, about 107 / ml, Also cultured in a 40°C, 70rpm shaking incubator, observed and recorded the amount of Deposit produced every 7 days, and added antagonistic bacteria C5 again at the same time, observed and recorded the final result after 14 days.

[0051] The whole experiment was divided into four treatments:

[0052] There are two comparison groups:

[0053] 1: A control group that was only inoculated with a...

Abstract

The method of reducing produced bacterial mud for papermaking process includes the following steps: adding a kind of dispersant into the bacterial mud and mixing fully and culturing; and adding one antagonist into the mixed liquid of the bacterial mud and the dispersant and mixing fully and culturing to reach the aim of reducing produced bacterial mud.

Description

(1) Technical field [0001] The invention relates to a method and a mixture for reducing the generation of bacteria slime, especially a method and a mixture for reducing the generation of bacteria slime in the papermaking process by using the characteristics of a dispersant and the antibacterial and sterilizing ability of beneficial microorganisms. (2) Background technology [0002] In the papermaking process, waste paper pulp is mostly recycled, but because the starch components and coatings in waste paper provide a very good source of nutrition, it is considered to be the main source of pollution for microorganisms, including bacteria and fungi. In addition, in order to reduce the waste of water resources, the paper mill adopts a closed water circulation system, which also provides favorable conditions for the growth of various microorganisms, such as temperature, pH value, and nutrients. Therefore, the microbial phase is further strengthened. The diversity and the growth o...
