The invention discloses a titania photocatalytic digestion device and its preparation method, falling into technical field of environment protection. The device includes titania-coated quartz glass sheets I and II with their titania-coated regions corresponding to each other. The quartz glass sheet I is mounted with a seal ring and matched with the quartz glass sheet II, to form a flow passage between their corresponding titania-coated regions. The inventive titania photocatalytic digestion device can improve ultraviolet light receiving intensity, increase contact area between waste water and titania, shorten photocatalytic digestion time, and improve photocatalytic digestion efficiency.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a TiO 2 Photocatalytic digestion device and preparation method thereof. Background technique [0002] At present, the eutrophication of water body has attracted people's attention. The deterioration of water quality caused by it seriously affects people's production and life. Phosphorus wastewater mainly comes from domestic sewage. Phosphorus in domestic sewage can exist in the form of organic phosphorus and inorganic phosphorus. This kind of phosphorus in different forms increases the difficulty of treatment. The methods to deal with these phosphorus-containing substances mainly include chemical oxidation and incineration and other methods, but these two methods exist to varying degrees or have low efficiency, cannot completely detoxify pollutants, and are prone to secondary pollution; or have a narrow range of use and are only suitable for specific pollutants;...
