Problems solved by technology

However, this material also has some disadvantages that limit its wide application. One of the disadvantages is that the reactants must be adsorbed on TiO 2 Catalytic reactions can only occur on the surface. However, in the secondary effluent of urban sewage plants, low-concentration estradiol is often accompanied by other high-conce

Example Embodiment

[0041] Example, a functionalized TiO based on molecular imprinting 2 The nanotube sewage disinfection and purification device is characterized in that the device is composed of a glass reactor (7), a quartz tube (3), an ultraviolet lamp (4), a glass baffle (5), and 17β-estradiol molecularly imprinted TiO 2 The nanotube (2), the water inlet (1), the water outlet (6) and the reflector (8) are composed. The glass reactor (7) is a rectangular parallelepiped, and its size is 200mm×150mm×50mm; in the two rectangular parallelepiped Diagonally open two semicircular holes with a diameter of 20mm respectively, and then use semicircular pipes to bond them through super glue to serve as the water inlet (1) and the water outlet (6); two 120mm×50mm glass baffles (5) are used respectively The super glue is glued on the upper and lower sides and one side of the glass reactor (7), thereby dividing the glass reactor (7) into three equal parts, and three circular holes are respectively opened on bo...

Abstract

The invention relates to a sewage sterilizing purification device based on a molecular imprinting functionalization TiO2 nanometer tube. The purification device is characterized in that the device is composed of a glass mold, a silica tube, an ultraviolet lamp, a glass baffle, the TiO2 nanometer tube of 17 beta-estradiol molecular imprinting, a water inlet and a water outlet as well as a reflector, and a water sample is treated by using the sewage sterilizing purification device based on the molecular imprinting functionalization TiO2 nanometer tube; and the degradation rate of the 17 beta-estradiol is 70% after 20 mins, the removal rate of colibacillus is lg per five after 120 mins, and the effect is ideal. The device can reconstruct the nanometer tube aiming at certain special pollutant due to the molecular imprinting action, so that the pollutant removal effect of the nanometer tube is improved, namely, the device can adjust aiming at different water quality conditions so as to remove optimal removal pollutant; and meanwhile, the device kills bacteria and pathogenic microorganisms, the device can remove part of organic substances such as incretion interfering substances, thereby achieving the dual effects of disinfection and purification.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a molecularly imprinted functionalized TiO 2 Nanotube sewage disinfection and purification device. Background technique [0002] Water is the basic element for the survival of human beings and all living things, and it is also an indispensable resource for safeguarding industry and agriculture and maintaining the health of natural ecology. The total amount of water resources remains unchanged in the natural cycle, but its water quality undergoes complex changes. Only when the water quality meets the necessary requirements can it become a usable water resource. With the increase of population, the development of industrial and agricultural production, and the increasingly serious pollution of water environment, the available water resources in many areas have been in crisis one after another, seriously restricting the development of society and economy. The water crisis...
