Reinforcement treatment of bisphenol waste water

Abstract

A fortified treatment of bisphenol waste water is carried out by adding ª‰-cyclodextrin into waste-water containing bisphenol substances in proportion of 5:1í½10:1, forming stable clathrate compound, and light degrading at normal temperature and pressure with ultraviolet light as light source. It can improve bisphenol substance light degradation efficiency by 40-60% and reaction speed ratio 2.3-11.0 times. It is cheap, simple and has no secondary pollution.

Description

technical field [0001] The invention relates to a selective strengthening treatment method for wastewater containing bisphenols. Background technique [0002] Bisphenols are the main chemical raw materials for the production of polycarbonate, epoxy resin, phenolic resin, polyacrylate and tooth sealant, etc., and have a wide range of applications in chemical industry, light industry, electronics, electromechanical, instrumentation, construction industry and food industry They can enter the environment through various channels during production and use. However, this is a typical type of environmental endocrine disruptors. After entering the human body and animals, they can cause dysfunction, such as reproductive disorders, developmental abnormalities, and certain immune disorders. Diseases of the system and nervous system have attracted great attention from academia and the public in recent years. Therefore, it is of great practical significance to human beings to deal with s...

[0002] Bisphenols are the main chemical raw materials for the production of polycarbonate, epoxy resin, phenolic resin, polyacrylate and tooth sealant, etc., and have a wide range of applications in chemical industry, light industry, electronics, electromechanical, instrumentation, construction industry and food industry They can enter the environment through various channels during production and use. However, this is a typical type of environmental endocrine disruptors. After entering the human body and animals, they can cause dysfunction, such as reproductive disorders, developmental abnormalities, and certain immune disorders. Diseases of the system and nervous system have attracted great attention from academia and the public in recent years. Therefore, it is of great practical significance to human beings to deal with such substances reasonably and safely. At present, the traditional methods for dealing with such substances are: chemical Oxidation method, electrochemical oxidation method, physical adsorption method, biodegradation and other methods, and these methods have certain problems in terms of processing time, efficiency and cost. For example, biological methods mainly use the metabolism of microorganisms, so the processing time is long , and the degradation efficiency is not high, the treatment cost of chemical oxidation and electrochemical oxidation is relatively high, and the physical adsorption method can only transfer pollutants from one state to another state, but cannot fundamentally solve the treatment problem of such substances. Therefore, an efficient, simple, economical and safe treatment method is needed, and the photochemical method developed in recent years provides a good solution for the treatment of toxic and harmful refractory persistent organic substances in the environment.
