UV/O3/H2O2 advanced oxidation reactor and process

Abstract

The invention discloses a UV / O3 / H2O2 advanced oxidation reactor and process. The UV / O3 / H2O2 advanced oxidation reactor comprises a water inlet pipe, a water outlet pipe, an ultraviolet reactor, an H2O2 adding facility and an O3 adding facility, wherein the ultraviolet reactor adopts a down-inlet up-outlet prancing type structure; a plurality of ultraviolet lamp groups are embedded in the ultraviolet reactor; the ultraviolet lamp groups and a partition plate are arranged at a certain angle; the water inlet pipe is connected with a water inlet formed in the lower part of the ultraviolet reactor;the water outlet pipe is connected with a water outlet is formed in the upper part of the ultraviolet reactor; a connection pipeline of the water inlet pipe is provided with the H2O2 adding facilityand the O3 adding facility; after raw water is pressurized, H2O2 with a certain concentration is added through the H2O2 adding facility, and ozone which is prepared by an ozone generator and has a certain concentration is added through a water injector and then enters into the ultraviolet reactor. According to the UV / O3 / H2O2 advanced oxidation reactor and the process disclosed by the invention, separate and united operations of three advanced oxidation ways including UV / O3, O3 / H2O2 and UV / H2O2 can be realized, the oxidation efficiency is improved, and a technological operation is more flexible.

Description

technical field [0001] The present invention relates to a kind of can realize UV / O 3 / H 2 o 2 The invention relates to a reaction system of an advanced oxidation mode, which belongs to the technical field of feed water treatment. Background technique [0002] With the development of social economy and the gradual improvement of people's living standards, people's requirements for water quality are getting higher and higher. The traditional water treatment process mainly removes suspended solids, colloids, bacteria, etc. in water, but is not effective in removing dissolved organic matter in water. Advanced Oxidation Process (AOPs) has been paid attention to as a advanced treatment technology for drinking water. UV / O 3 , O 3 / H 2 o 2 and UV / H 2 o 2 The three advanced oxidation processes can produce highly oxidizing hydroxyl radicals ( OH). Through the strong oxidizing properties of OH, organic pollutants can be quickly and thoroughly oxidized, and the odor substances...

AI Technical Summary

Problems solved by technology

Usually ozone oxidation needs to set up an ozone contact tank, its hydraulic retention time is generally not less than 15min, the water depth is about 7m, the utilization rate of ozone is low, and bromate is easy to be produced

At the same time, there is a lack of relevant technology and research in the design of the ultraviolet reactor and the layout of the ultraviolet lamp. At present, the common ultraviolet reactor is mostly cylindrical, and the hydraulic retention time is relatively short.
