preparation example Construction

[0025] The preparation method of the active bacteria growth-promoting nutritional additive is as follows:

[0026] (1) Take Trichoderma and inoculate it on a PDA plate according to the inoculum amount of 2~5%, culture it at 25~30°C for 3~6 days, take the mycelium and wash it with sterile water. After washing, the mass ratio is 1~3: 9~15 was added to a sodium chloride solution with a mass fraction of 0.9%, and diluted to 10 -6 For the dilution level, take the diluted liquid and inoculate it into the nutrient culture medium at an inoculation amount of 2-5%, and cultivate it at 25-30°C and 180r / min for 1-3 days to obtain a culture;

[0027] (2) Take rice straw and add it to sugar factory filter mud according to the mass ratio of 3~5:2~4 to obtain a mixture, take the mixture, take the mixture according to the mass ratio of 1~3:4~6, add magnetized water to mix, and sterilize at 115°C After 30 minutes, the sterilized product was obtained, and the culture was inoculated into the ste...

Abstract

The invention discloses a biostimulant used for papermaking wastewater and a preparation method thereof and belongs to the field of papermaking wastewater biochemical treatment. In the invention, ricestraw and filter sludge from sugar refinery are used as raw materials for being decomposed to generate active components, that can promote microorganisms to grow in a relatively bad environment quickly to a large amount and form excellent zoogloea, thereby increasing the degradation efficiency on organic pollutants by the microorganisms; with nickel chloride hexahydrate water solution being a rawmaterial, pollutant degradation is directly carried out to increase efficiency; by compounding xylanase and pectase, during the treatment process, some refractory macromolecular organics can be degraded, thus increasing the treatment effectively of the biochemical system; by adding Ruminococcus flavefaciens and Rhodopseudomonas palustris to the biostimulant, activity competition among bacteria floras in the papermaking wastewater is enhanced, so that a more advantageous papermaking wastewater treatment bacteria can be formed during the growth of the bacteria floras. The biostimulant solves the problem of low efficiency of the papermaking wastewater treatment with biostimulants in the prior art.

Description

technical field [0001] The invention relates to the technical field of biochemical treatment of papermaking wastewater, in particular to a biological growth promoter for papermaking wastewater and a preparation method thereof. Background technique [0002] With the development of industry and agriculture and the continuous increase of population, whether it is urban sewage, industrial sewage or agricultural nutrient-rich sewage, the technological development of sewage treatment has been put on the agenda. The amount of sewage has increased sharply, and it is common for sewage to be directly discharged into rivers without treatment, resulting in a decrease in the carrying capacity of surface water bodies, and the pollution problem has become increasingly prominent, seriously restricting the economic development of cities and industries, and threatening people's health. In recent years, the major progress and development in the field of water treatment have focused on the biof...
