Abstract

The invention discloses a degradation treatment method for eichhornia crassipes. According to the technical scheme, a sodium chloride electrolyte solution with a low concentration is electrolyzed to prepare electrolyzed oxidizing water (EOW), the EOW is acid electrolyzed exidizing water with a high oxidation-reduction electric potential and a low concentration and can damage lignin wrapping cellulose, the lignin and cellulose are separated, hemicellulose is subjected to a hydrolysis reaction, the contact area between the hemicellulose and a reactant generated by reducing sugar in the later period is increased, and a biochemical reaction is promoted, so that the sugar rate and the anaerobic fermentation enzymolysis speed in the later period are increased; the EOW has the advantages of beingfree of toxicity, safe, environmentally friendly and the like, the harm of adopting a diluted acid solution to the environment can be avoided, and the method is friendlier to the environment.

Description

technical field [0001] The technical proposal belongs to the field of microbial fermentation engineering, and specifically relates to a degradation treatment method of water hyacinth. Background technique [0002] Water hyacinth is a vicious aquatic weed. It reproduces rapidly and often leads to obstruction of shipping, blockage of rivers, and damage to aquatic ecosystems. If it can be prevented and controlled, it can be used to degrade organic matter. Pollution of water bodies, treatment of industrial wastewater, purification of eutrophic rivers, restoration of water bodies polluted by heavy metals, etc. Through pretreatment, water hyacinth can be hydrolyzed into reducing sugar, which provides guarantee for biomass fuels such as ethanol in the development and application of biomass energy. However, because there are many hydrogen bonds between the cellulose molecules and it contains a large number of hydroxyl groups, resulting in a dense crystal structure, it is difficult ...
