Title:
WATER TREATMENT AGENT USED IN PERFUME PRODUCTION PROCESS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/045594
Kind Code:
A1
Abstract:
The present invention relates to a water treatment agent used in a perfume production process and a preparation method therefor, which belong to the technical field of water treatment agents. The water treatment agent is prepared by the following steps: mixing iron-based montmorillonite and deionized water, then adding modified cyclodextrin, and stirring and reacting same for 24 h to obtain a water treatment agent used in a perfume production process. Since synthetic perfume wastewater contains a large amount of organic matter that is difficult to degrade and that has a toxic effect on microorganisms and also lacks nutrient element phosphorus, treating such wastewater by directly using a biochemical process is extremely ineffective and sometimes even impossible to operate. By means of chemical oxidation, a lot of organic matter that is toxic, harmful and difficult to degrade in the wastewater can be converted into micro-toxic, non-toxic and easily-degradable substances.
