Description

TECHNICAL FIELD

[0001] The utility model relates to water body purification technical field, concretely is a kind of water body bisphenol A processing device of adsorption and photocatalysis cooperation. BACKGROUND

[0002] Bisphenol A, also known as BPA, is difficult to dissolve in water, and is a kind of organic compound with very strong hydrophobicity. Bisphenol A is the main raw material for producing polycarbonate, epoxy resin and other high molecular materials, and can also be used for producing plasticizer, flame retardant antioxidant, heat stabilizer, rubber antioxidant, pesticide, paint, fuel and other fine chemical products, and the social demand is huge. According to statistics, 27 million tons of BPA-containing plastics are produced in the world every year. The production and use of bisphenol A products (plastic products, rubber products, paint and pesticide, etc.) can cause a large amount of bisphenol A to enter various water bodies through various channels. Bisphenol A can be detected in a large amount in river water, lake water, domestic sewage and influent and effluent of sewage treatment plant, and even in some drinking water. The concentration distribution shows great difference. Secondly, BPA is also a typical environmental endocrine disruptor. Even a small amount of BPA can cause animal reproductive disorder, sex organ variation, sex reversal and femaleization, leading to an increase in the incidence of human infertility, obesity, diabetes, immune function decline, heart disease, tumor and neural defect, and causing great harm to human health and ecological environment. The treatment of bisphenol in water environment has become a hot and difficult point of water environment treatment and has attracted widespread attention from the society.

[0003] At present, a small amount of bisphenol A substance has been detected in some drinking water. If it is not treated before use, it will pose a threat to human health. The conventional water treatment device is mainly used in sewage treatment plant to adsorb bisphenol A by activated carbon. However, activated carbon has a certain adsorption limit and needs to be replaced regularly. In addition, the contact area between sewage and activated carbon is short, and the treatment efficiency of bisphenol A is low. Therefore, it is particularly important to design an effective and targeted device to remove bisphenol A from water.

[0004] Photocatalysis technology is one of the most promising deep water treatment technologies, which is green, environmentally friendly and has high catalytic efficiency. Titanium dioxide photocatalyst is widely used for photocatalytic degradation of organic pollutants due to its high catalytic efficiency, stable physical and chemical properties, non-toxicity and low cost. Activated carbon has developed pore structure and high specific surface area, large adsorption capacity, strong chemical stability, insolubility in water and organic solvents, and is used as an excellent carrier for photocatalyst, which has high removal effect on organic matter.
