Preparation method of industrial sewage treatment fungicide

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.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a preparation method of an industrial sewage treatment bacterial agent. Background technique [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 m...

[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
