Description

Resource utilization method of glucosamine production waste residue and application thereof
Technical Field
The invention relates to the technical field of glucosamine, in particular to a resource utilization method of glucosamine production waste residues and application thereof.
Background
Glucosamine is an intermediate for synthesizing articular cartilage and synovial fluid molecules, is an important participant of human metabolism, and currently, China has become the largest world-wide glucosamine producing country. Currently, the method for preparing glucosamine by a microbial fermentation method is a method commonly used by enterprises, and mainly comprises the steps of inoculating microorganisms to a culture medium, carrying out large-scale culture and proliferation by taking glucose as a raw material, carrying out microbial metabolism to generate glucosamine, filtering a fermentation liquid to remove microbial cells, and then carrying out processes of decolorization, purification, concentration, freeze-drying and the like on a filtrate to prepare a glucosamine finished product. Although the microbial fermentation method has the advantages of high conversion efficiency, stable product quality, low production cost and the like, the method has the problem that a large amount of filtered thallus waste residues are difficult to treat, enterprises generally produce a large amount of wet thallus every 1 ton of glucosamine produced by the enterprises, and a large amount of thallus waste residues are usually discarded, buried or burned as garbage every year, so that not only is environmental pollution easily caused, but also resource waste is caused.
Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme.
Firstly, a resource utilization method of glucosamine production waste residue is disclosed, which comprises the following steps:

Further, in the step (1), the thallus waste residue is dried at the temperature of 90-115 ℃ to constant weight, and then is crushed and sieved by a 200-300-mesh sieve, so that thallus waste residue powder is obtained. And the wet thallus is hardened into a whole after passing through the back plate, is made into powder through drying, is convenient to mix with other raw materials, and has higher water content.
Optionally, in the step (2), the particle size of the calcium carbonate powder and the MXene material powder is 150-200 meshes.
Further, in the step (2), the ratio of the thallus waste residue powder to the calcium carbonate powder to the MXene material powder in parts by weight is 1.5-1.8: 0.2-0.35 parts: 0.3 to 0.38 portion. The three are premixed and then subjected to wet granulation, so that precursor particles with thallus waste residue powder as a continuous framework and calcium carbonate powder and MXene material powder as uniformly dispersed phases can be obtained, and a foundation is laid for preparing the adsorbent with a special microstructure and components.
Further, in the step (2), before wet granulation, water accounting for 20-25% of the total mass of the thallus waste residue powder, the calcium carbonate powder and the MXene material powder is added to moisten the powder, or water in corresponding proportion is added according to specific needs to bond the powder, so that wet granulation is performed conveniently.

The high-efficiency adsorbent prepared by the invention not only contains micropores generated by the carbonization of the thallus waste residue, but also has micropores left by the removal of calcium carbonate powder in the subsequent acid leaching treatment, and the aperture of the micropores is generally larger than that of the micropores generated by the carbonization of the thallus waste residue, namely, the calcium carbonate powder is used as an activating agent of a porous carbon skeleton in the adsorbent and can also be used as a pore-forming agent. The adsorbent can utilize the micropores with small pore diameters generated by the carbonization of the thallus waste residues to adsorb pigment in fermentation liquor, hydrolysate for preparing glucosamine or chloride ions in the hydrolysate, and the micropores with large pore diameters left by removing residual calcium carbonate are convenient for the entry of the fermentation liquor or the hydrolysate, thereby improving the efficient adsorption of the pigment and the chloride ions. Meanwhile, the MXene material is added to remarkably promote the adsorption of chloride ions and the like in the hydrolysate, and the MXene material is of a layered structure with accordion-shaped microscopic characteristics and has huge surface area and abundant surface functional groups, so that the MXene material can quickly adsorb and contain chloride ions, the chloride ions are stably adsorbed in the MXene material, and the MXene material is helpful for more thoroughly removing the chloride ions in the hydrolysate. When the desorption is needed, the adsorbent is boiled by using clean water to separate chloride ions from the adsorbent, and the adsorbent can be recycled after being dried.
