Technical Field
The invention relates to the technical field of chemical waste liquid treatment, in particular to a method for preparing ecological fibers by using industrial waste water containing water-soluble silicon and application thereof.
Background
In the industrial production process of water-soluble silicon, the gasified silicon element component is recovered by a special method of continuously burning and moxibustion for more than 8 hours by adopting a high-temperature physical extraction method, and the harmful component is subjected to neutralization decomposition and then is rapidly cooled to form soluble crystal (SiO)3). In the rapid cooling process (commonly called as the water-excited material process), silicon crystals are combined with water, and the silicon is dissolved in water to form ionic free molecules, so that a large amount of industrial wastewater containing water-soluble silicon is generated. The industrial wastewater containing the water-soluble silicon element contains the water-soluble silicon element, and the characteristics are as follows: 1. physical properties: the soluble crystal is in a green, colorless, white, transparent or semitransparent amorphous crystal shape; dissolving in water, and preparing silicon liquid with different contents according to the application; 2. chemical characteristics: no radioactivity, no explosiveness, no toxicity and no sterility; 3. the specific gravity is 1.0; 4. ultra-strong permeability: the water-soluble silicon element has 0.4 nanometer tiny molecules, so the water-soluble silicon element can quickly permeate into plant fibers, has extremely strong permeability to the plant fibers, and quickly permeates into the plant fibers to decompose the plant fibers; 5. super-strong bactericidal property: mainly embodied in the strong instant sterilization function on escherichia coli and legionella (gram-negative bacteria). No black smelly liquid is produced during the fiber rinsing process.
Cellulose in plants is difficult to decompose, and for this reason, various physical, chemical, and biological methods are used in industrial production. However, practice proves that various different process methods have advantages and defects, the problem of unmatched process routes and technical methods in comprehensive application exists, and high unification of ecological benefits and economic benefits is difficult to realize.
Therefore, the invention selects the plasma self-oscillation effect of fully exerting the water-soluble silicon element, adopts the innovative process technology of repeatedly overlapping and activating the cellulose enzyme to decompose the fiber by a physical method and a biological method, realizes the three-free process of no pollution, no chemical additives and no production wastewater and waste materials in the whole production chain, and has highly uniform ecological benefit and economic benefit.
