Problems solved by technology

[0002] The composition of industrial wastewater is complex, especially a large number of artificially synthesized compounds entering the environment, such substances are mainly alkanes, olefins, alicyclic hydrocarbons, aromatic hydrocarbons, and artificially synthesized organic substances, especially macromolecules, refractory, toxic and harmful Substances such as phenol, chlorophenol, cresol, nitrophenol, etc., aromatic hydrocarbons, cyanides, amines, and ammonia nitrogen enter the environment with the wastewater or solid waste discharged from the factory. Due to the complexity of the structure of these substances and the biological Unfamiliarity, it cannot be decomposed and utilized by microorganisms in a short period of time. The traditional wastewater treatment method using activated sludge to cultivate and domesticate microorganisms can no longer effectively remove these pollutants. These substances have accumulated in the environment for a long time and provide us with survival The ecological environment has caused great pollution, which has brought great harm to human physical and mental health.
[0003] At present, industrial wastewater treatment methods mainly include physical methods such as reverse osmosis, distillation, and soil irrigation; chemical methods include ion exchange, ammonia stripping, chemical precipitation, breakpoint chlorination, electrodialysis, electrochemical treatment, and catalytic cracking; biological methods include Nitrification and algae culture, however, the physical treatment effect is not good, compared with the chemical method, the biological treatment method is an effective method to control industrially polluted water bodies

Embodiment 1

[0050] Preparation of chitosan derivatives:

[0051] Dissolve chitosan in 1% acetic acid and stir until completely dissolved. Add 4-amino-2-nitrodiphenylamine-2'-formic acid according to the molar ratio of 4-amino-2-nitrodiphenylamine-2'-formic acid to chitosan as 1.38:1; then N-hydroxyl Succinimine (the molar ratio of N-hydroxysuccinimine to chitosan is 1.1:1) was dissolved in 1.5 mg / mL of EDC, then added to the above mixed solution, continued to stir until completely dissolved, then adjusted the pH to 8.5, then Stir for 24h. Then put the solution into a dialysis bag and put it into distilled water for dialysis for 3 days, during which time the distilled water was replaced. Then the dialysis bag was transferred to PEG solution to concentrate for 2 days. Then take the concentrated solution and add acetone (1:2) to precipitate the modified chitosan for 10 hours. The solution was centrifuged (15000 rpm), and the precipitated part was washed with absolute ethanol for 3 times,...

Embodiment 2

[0059] The preparation of chitosan derivative is identical with embodiment 1.

[0060] A bacterial agent for industrial sewage treatment, comprising, as main ingredients, by weight parts, 11 parts of Chryseobacterium indole-producing, 7 parts of Pseudomonas putida, 4 parts of Nitrosoma, and 4 parts of Acinetobacter ruckeri.

[0061] Nutrient ingredients, in parts by weight, include 4 parts of sodium ascorbate and 0.7 part of riboflavin.

[0062] Solid matrix, in parts by weight, 17 parts of perlite and 7 parts of chitosan derivatives.

[0063] The preparation of the bacterial agent for industrial sewage treatment was the same as in Example 1.

Embodiment 3

[0065] The preparation of chitosan derivative is identical with embodiment 1.

[0066] A bacterial agent for industrial sewage treatment, comprising, in parts by weight, 9 parts of Chryseobacterium indolegenes, 6 parts of Pseudomonas putida, 6 parts of nitrosobacter, and 5 parts of Acinetobacter ruckeri.

[0067] Nutrient ingredients, in parts by weight, include 4 parts of sodium ascorbate and 0.6 part of riboflavin.

[0068] Solid matrix, in parts by weight, 19 parts of perlite and 6 parts of chitosan derivatives.

[0069] The preparation of the bacterial agent for industrial sewage treatment was the same as in Example 1.

Abstract

The invention discloses a preparation method of an industrial sewage treatment fungicide, and relates to the technical field of water treatment. The microbial inoculum comprises the following raw material components: a main material which is compound bacteria and comprises indole-producing Chryseobacterium, Pseudomonas putida, nitrosobacteria and Acinetobacter lwoffii; the nutritional ingredients comprise caffeoyl malic acid, sodium ascorbate and riboflavin; the solid substrate comprises perlite and a chitosan derivative. After the microbial agent prepared by the invention is added, the biological enhancement effect can be remarkably improved, and the effect of removing organic pollutants such as BOD and ammonia nitrogen in sewage is enhanced; in addition, the removal effect of the bacterial agent on berberine and heavy metal ions is also remarkably enhanced. The microbial agent can be applied to biochemical treatment of livestock and poultry breeding wastewater, industrial organic wastewater, river black and odorous water, kitchen waste anaerobic digestion biogas slurry and the like, and has high application value; the method is used for treating organic wastewater and is high in treatment efficiency, good in economic benefit, convenient to operate and free of pollution.
