Description

Technical Field

[0001] This invention belongs to the field of bamboo wastewater utilization technology, specifically relating to a preparation containing high-temperature heat treatment spray wastewater of bamboo, its preparation method and application. Background Technology

[0002] Bamboo applications generally require high-temperature heat treatment, from bamboo charcoal production to drying or carbonizing bamboo at various temperatures. During this process, components of the bamboo are discharged as waste liquid along with the saturated steam medium used to isolate them from oxygen. This waste liquid contains a large amount of bamboo extracts and degradation products of cell wall substances such as hemicellulose and cellulose at high temperatures. It generally has a high acid buffering capacity and is rich in organic acids, phenols, and sugars, resulting in high levels of chemical oxygen demand (COD) and biological oxygen demand (BOD). Direct discharge can cause eutrophication of water systems and the accumulation of biotoxic substances. In the current environment of environmental protection, green manufacturing, and carbon neutrality, the treatment cost of bamboo processing waste liquid is increasing, leading to the transformation and closure of some small and medium-sized enterprises, thus affecting the development of the bamboo processing industry.

[0003] Directly purifying bamboo processing wastewater through multiple stages before discharge not only results in high treatment costs but also represents a significant waste of resources. Effective development and utilization of this wastewater is of great importance to the bamboo processing industry. Currently, the main method of utilization involves separating the components of the wastewater to purify phenols or organic acids for the manufacture of cosmetics, anti-inflammatory and antibacterial drugs, detergents, etc. However, this process consumes large quantities of toxic and harmful chemical reagents and suffers from problems such as low purity and low yield of the target product. Summary of the Invention

[0004] The technical problem this invention aims to solve is to address the shortcomings of the existing technology by providing a formulation containing high-temperature heat treatment spray wastewater from bamboo, its preparation method, and its application. This method comprehensively utilizes the high-temperature heat treatment spray wastewater from bamboo, combining phenolic oxidation treatment, stability improvement, and adhesion enhancement for pest and disease control, reducing pesticide usage, and simultaneously reducing the treatment cost of bamboo heat treatment spray wastewater. It transforms waste into treasure, extends the bamboo processing industry chain, brings additional profits to processing enterprises, achieves comprehensive energy utilization, and contributes to the development of pollution-free ecological agriculture.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a preparation containing high-temperature heat treatment spray waste liquid of bamboo, wherein the preparation containing high-temperature heat treatment spray waste liquid of bamboo comprises the following final contents added to the high-temperature heat treatment spray waste liquid of bamboo: potassium permanganate mass fraction 0.5% to 1.2%, sodium dodecylbenzenesulfonate 0.1 mg / L to 0.6 mg / L, trisodium citrate 0.2 mg / L to 0.5 mg / L, a mixture of Span 80 and Tween 80 mass fraction 2% to 5%, and rare earth element nitrate mass fraction 0 to 5‰, wherein the rare earth element in the rare earth element nitrate is cerium, lanthanum or neodymium.

[0006] Preferably, the mass fraction of the rare earth element nitrate is 0.15‰ to 5‰.

[0007] Preferably, the source of the bamboo high-temperature heat treatment spray waste liquid is: waste liquid containing bamboo extracts and pyrolysis products that condenses from atomized water during the bamboo high-temperature heat treatment process at a temperature >180℃.

The high-temperature heat treatment temperature is higher than 180℃, and it mainly comes from the high-temperature carbonization, carbonization treatment and dry distillation processes of bamboo.

[0025] In this embodiment, the source of the high-temperature heat treatment spray waste liquid for bamboo is as follows: atomized water is continuously introduced into the drying kiln to maintain the oxygen content in the drying kiln at <3%. Bamboo with an initial moisture content of 10% to 12% is heat-treated at a temperature of 200°C for 120 minutes. After the heat treatment is completed, the high-temperature heat treatment spray waste liquid for bamboo is obtained. The pH value of the high-temperature heat treatment spray waste liquid for bamboo is 4.0, and the total phenol content is >1.2 mg / L.
