Abstract

The invention relates to the technical field of water disinfection and purification. The embodiments of the invention provide an ultraviolet oxidation water purification method and device. The methodincludes the following steps: emitting ultraviolet light of 253.7 nm used for being reacted with an oxidizing substance and ultraviolet light of 185 nm used for radiating to to-be-purified water basedon a low-voltage ultraviolet lamp so as to generate hydroxyl radicals to oxide organic matters in the to-be-purified water, wherein the low-voltage ultraviolet lamp is sealed in a quartz glass sleeveand the space between two layers of quartz glass of the quartz glass sleeve is filled with inert gas and/or nitrogen. In this way, the ultraviolet oxidation water purification method and device realize that no oxidizing substance is added in a water purification process and can ensure the radiation efficiency and water purification effect of the ultraviolet light.

Description

technical field [0001] The invention relates to the field of water disinfection and purification, in particular to an ultraviolet oxidation water purification method and device. Background technique [0002] Sewage, reclaimed water, tap water, and drinking water pass through biochemical, sand filtration, membrane filtration and other processes, and there are still problems of excessive organic matter. Biochemical degradation, electrochemistry, ozone, hydrogen peroxide, Fenton advanced oxidation and other processes are used to degrade organic matter, and some organic matter passes through these processes. The process still cannot be degraded to the requirements of relevant regulations or the cost of degradation is high, so ultraviolet advanced oxidation process is required. Among them, ultraviolet advanced oxidation refers to 253.7nm (or other similar wavelengths, generally 253.7nm is used at present, the following is abbreviated and will not be repeated) ultraviolet radiat...
