Embodiment 1

[0039] The present invention proposes a biopharmaceutical bacteria slag catalytic oxidation treatment system, the treatment system includes a pretreatment unit 1, a heat exchange unit 2, an oxidation matrix unit 3, a reactor 4, a separation unit 5 and a catalyst dosing unit 17, the The reactor 4 is connected to the heat exchange unit 2, the oxidation substrate unit 3 and the separation unit 5 respectively, and the pretreatment unit 1 is connected to the heat exchange unit 2, the separation unit 5 and the catalyst adding unit 17 respectively.

[0040] Described pretreatment unit 1 comprises the bacteria residue storage tank 7 that stores biopharmaceutical bacteria residue, the preprocessor 8 that is connected with described bacteria residue storage tank 7 and catalyst dosing unit 17, the solid pump that transports bacteria residue and is arranged on The agitator in the preprocessor 8 and the catalyst added by the catalyst adding unit 17 are alumina-based Cu-Fe-Mn three-way catal...

Embodiment 2

[0064] Another object of the present invention is to provide a method for treating fungus residue, which includes the following steps:

[0065] A. The biopharmaceutical slag stored in the slag storage tank 7 is injected into the preprocessor 8 with a solid pump, mixed with the liquid-phase reflux water of the separation unit 5 in the preprocessor 8, and added through the catalyst dosing unit 17 Alumina-based Cu-Fe-Mn three-way catalyst, formulated as a material with a moisture content of 90%. The bacteria residue with a water content of 75% to 85% in the bacteria residue storage tank 7 is mixed with the liquid-phase reflux water to form a material with a moisture content of 90%. The liquid-phase circulating water is acidic with a pH of 4 to 5. Under the action of acid, the biopharmaceutical slag will break down, causing some cells to dissolve and free water to increase. Moreover, due to the high temperature of the reflux water, the original slag will be obtained. warm up. Un...

Abstract

The invention relates to a catalytic oxidation system and method for treating bio-pharmaceutical fungal residues. According to the invention, high temperature and high pressure are utilized to allow the walls of cells in the fungal residues to be broken and intracellular water to be removed, so subsequent solid-liquid separation is facilitated; more importantly, the principles of hydrothermal oxidation are utilized to allow organic matters in the fungal residues to undergo liquid-phase oxidation, released heat is used for maintaining a high-temperature high-pressure environment needed in a reaction, and reacted materials are used for preheating an initial material via a high-efficiency heat exchanger, so energy consumed in transformation heat of water is reduced, and thus, energy investment is lowered, and operation cost is saved; and through addition of an alumina-based Cu-Fe-Mn three-component catalyst, catalytic oxidation efficiency is greatly improved, energy is saved and cost is reduced. The catalytic oxidation system and method provided by the invention overcomes the problems of great consumption of resources, low treatment efficiency, small decrement, great equipment-occupied area and great odor of conventional treatment processes for bio-pharmaceutical fungal residues, and realizes quantitative reduction, harmless treatment and recycling of bio-pharmaceutical fungal residues.

Description

technical field [0001] The invention relates to a biopharmaceutical fungus residue treatment system and method, in particular to a biopharmaceutical fungus residue catalytic oxidation treatment system and method. Background technique [0002] Fermentation pharmaceutical companies will produce a large amount of waste bacteria residue in the production process, the main components are the mycelium of drug-producing bacteria, unused medium, metabolites produced during the fermentation process, degradation products of the medium, and a small amount of Pharmaceutical active ingredients, etc. The moisture content of biopharmaceutical fungus residue is generally 70% to 93%, the crude protein content is 30% to 52% and the crude fat content is 2% to 20% on a dry basis. The residual culture medium, antibiotic matrix and its degradation products in the bacteria residues are potentially harmful to the ecological environment and human health, and have become the focus of environmental m...
