Antimicrobial waste residue anti-mildew agent and preparation method thereof

Abstract

The invention relates to an antibiotic waste residue anti-mildew agent and a preparation method thereof. The anti-mildew agent is a liquid anti-mildew agent, which is prepared from the following components and raw materials with mass percentage content: 1% to 20% of sulfur, hydrogen oxidized Sodium 5% to 20%, citric acid 5% to 15%, ethanol 5% to 15%, water 40% to 80%, sulfur is dissolved in sodium hydroxide, ethanol, citric acid and water to prepare liquid anti-mildew agent. Compared with the prior art, after using the anti-mildew agent for antibiotic waste residue, the problem of mildew in stacking can be overcome. The invention can be directly sprayed on the antibiotic waste residue, and has the characteristics of long mildew inhibiting time, low production cost, simple preparation process and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an antibiotic waste residue anti-mildew agent and a preparation method thereof. Background technique [0002] my country is the world's largest producer and exporter of antibiotic raw materials, producing more than 70 kinds of antibiotics, accounting for 70% of the world's total production. The raw materials used in the production of antibiotics are complicated, and the bacterial residue produced by the fermentation method contains a small amount of antibiotics, various amino acids, crude proteins, and various trace elements, which makes the antibiotic waste residue a good natural medium for microorganisms. [0003] At present, due to the lack of timely and appropriate treatment methods in the treatment, storage, and transportation of antibiotic waste residues, when the environmental conditions meet the growth needs of microorganisms, they will grow a...

Problems solved by technology

[0004] At present, the antifungal agents used in the domestic market mainly have the following problems: (1) The first category is natural antibacterial materials, including chitin, chitosan and insect antibacterial proteins extracted from animals. The sources are limited, the price is high, and there are few applications in industrial products; the second category is organic antibacterial and antifungal materials, mainly including quaternary ammonium salts, quaternary phosphonium salts, biguanides, alcohols, phenols, organic metals, and pyridines , imidazoles, etc. The biggest advantage of organic antibacterial materials is good antibacterial timeliness, but there are problems such as high toxicity, poor persistence, and drug resistance; the third category is inorganic antibacterial and antifungal materials, mainly oxide photocatalytic materials and metal Ionic metal oxide type has the advantages of broad-spectrum antibacterial, long-term effect, no drug resistance, heat resistance, etc., but the overall antibacterial timeliness of inorganic antibacterial agents is weaker than that of organic antibacterial materials, and these substances are more or less safe. Or environmental hazards, after adding, waste residue will cause secondary pollution, and the actual anti-corrosion effect is also affected by other factors

Some are restricted or even prohibited by national laws and regulations

(2) In the same formulation, the antifungal agent mainly plays an antifungal function; however, due to differences in its physical and chemical properties, it is generally necessary to add other additives to the formulation to improve its internal performance, which not only increases the production cost, but also makes production and transportation more difficult. , storage, and use processes are complicated, increasing uncontrollable risks and costs

[0005] According to patent search and literature search, there is no report related to the use of waste residue antifungal agent in China
