Abstract

The invention relates to a preparation method of a nano titanium dioxide material for cleaning a water body, which comprises the following steps: S1, first nitrogen enters a vaporizer through a first pipeline and is mixed with titanium tetrachloride to form a first mixture, and the first mixture is conveyed to a first reactor through second nitrogen conveyed by an inner pipe of a second pipeline; s2, the preheated oxygen enters a first reactor through an outer pipe of a second pipeline, meanwhile, third nitrogen is injected into the first reactor through a third pipeline to cool the reaction process, and nanometer titanium dioxide is formed; s3, injecting the activated carbon into a second reactor through a first feed port; s4, injecting the nano titanium dioxide generated in the step S4 into a second reactor through a second feed port, and stirring with activated carbon to form a second mixture; s5, filtering the second mixture, drying, and roasting to form supported nano titanium dioxide; and step S6, repeating the steps S4-S5 until qualified supported nano titanium dioxide is produced. According to the invention, all parts are controlled by the central control unit to produce qualified nano titanium dioxide.

Description

technical field [0001] The invention relates to the field of nano-titanium dioxide, in particular to a method for preparing a nano-titanium dioxide material used for cleaning water bodies. Background technique [0002] Nano-titanium dioxide material is a functional nanomaterial that has developed rapidly in recent years. In addition to the unique surface effect, small size effect, quantum effect and macroscopic quantum tunneling effect of nanomaterials, it has been confirmed to have excellent photocatalytic activity, Multiple properties such as chemical stability, thermal stability, superhydrophilicity, non-migration and non-toxicity. [0003] At present, the toxic and harmful substances in sewage still have the problem that they cannot be removed and are difficult to degrade. The current water treatment processes such as coagulation, sedimentation, and biological oxidation, as well as purification technologies such as activated carbon adsorption and membrane treatment, are ...
