UV/H*O* advanced oxidized water treatment equipment and treatment method

Abstract

The invention relates to a UV / H2O2 advanced oxidized water treatment equipment and a treatment method. The UV / H2O2 advanced oxidized water treatment equipment comprises a H2O2 adding device and a reactor, wherein the H2O2 adding device is formed by a dosing tank, a flowmeter and an ejector which are orderly connected; and the reactor comprises a shell, an ultraviolet lamp arranged on an axis line inside the shell, and an annular glass tube which surrounds outside the ultraviolet lamp and is communicated with a water inlet and a water outlet of the shell. The water treatment method comprises the following steps that: a H2O2 solution is pre-prepared and placed into the dosing tank, and H2O2 is continuously added into the solution through the siphon of the ejector and the mixture is mixed; and raw water added with the H2O2 flows into the reactor from a water outlet of the ejector through the water inlet of the shell of the reactor, and flows from the bottom up along the annular glass tube under the irradiation of the ultraviolet lamp. The treatment equipment and the treatment method can realize the automatic adding of the H2O2, can effectively prolong the irradiated time of water by ultraviolet rays, have simple process operation, only need to regularly supplement the H2O2 solution, and are suitable for the deep treatment of the water of municipal water distribution networks of cities.

Description

technical field [0001] The present invention relates to a UV / H 2 o 2 The advanced oxidation water treatment equipment and treatment method belong to the technical field of water treatment equipment. Background technique [0002] With the continuous development of modern industry, waste water containing a large amount of toxic, harmful and biodegradable pollutants is discharged into the environment, causing serious pollution of water quality. Conventional water treatment processes such as coagulation, sedimentation, filtration, and disinfection traditionally adopted by water plants have been difficult to cope with the complex water quality of water sources. The water quality problems of the effluent from the water plant are concentrated in the aspects of odor, many disinfection by-products, poor chemical stability and biological stability of the water quality, especially when the factory water is transported to the user through a complex and huge pipe network system Due to...

AI Technical Summary

Problems solved by technology

But in UV / H 2 o 2 process, H 2 o 2 The photolysis efficiency is low, so it is necessary to add a high concentration of H 2 o 2

But from a toxicological point of view, high concentrations of H 2 o 2 is not feasible

And H 2 o 2 The reaction with chlorine is rapid, so the excess H 2 o 2 It is necessary to remove by biological filtration, which also increases the processing cost to a certain extent
