Abstract

The invention discloses a tubular ultraviolet light based oxidation device for removing total organic carbon (TOC) by using ozone in the technical field of water purification. The device comprises a tube, an aerator tube and two groups of quartz sleeves internally provided with an ultraviolet lamp, wherein two ends of the tube are respectively connected with a water inlet pipeline and a water outlet pipeline, and the two groups of quartz sleeves are fixedly arranged in the aerator tube and symmetrically arranged by taking the axis of the tube as a symmetrical axis. The design of the aerator sleeve in the invention introduces air (oxygen) to the surface of the ultraviolet lamp, which avoids the strong absorption of the water to 180nm-190nm ultraviolet radiation while improving the oxygen concentration of a radiation zone, and greatly improves the generation amount of photoinduced ozone; and carrier gas with pressure ensures that the ozone generated on the surface of the lamp tube can uniformly spread in pipelines within an extremely short time, thereby improving the oxidation efficiency of a reactor.

Description

technical field [0001] The invention relates to a device in the technical field of water body purification, in particular to a tube-type ultraviolet light-based ozone removal total organic carbon (TOC) oxidation device. Background technique [0002] TOC is one of the main pollution indicators of water bodies. In addition, as the concentration of trace organic pollutants such as PPCPs (pharmaceuticals and personal care products) in water bodies continues to increase, people pay more and more attention to advanced oxidation processes for TOC removal in water treatment processes. The existing advanced oxidation methods mainly include chemical dosing methods, such as adding potassium permanganate, chlorine dioxide, hydrogen peroxide and ozone, etc., but the oxidation process of potassium permanganate and chlorine dioxide will produce manganese dioxide and Chlorite ion and other secondary pollution, while the oxidation products of hydrogen peroxide and ozone have no secondary pol...
