Ultrasonic atomization high-voltage discharging and ozone-ultraviolet combined oxidization digestion device

Abstract

The invention provides an ultraviolet atomization high-voltage discharging and ozone-ultraviolet combined oxidization digestion device, comprising an ultrasonic atomization reaction chamber, a high voltage discharging reaction chamber, an ozone generator and three quartz spiral tubes internally provided with ultraviolet lamps, which are connected with each other through a peristaltic pump, a circulating air pump and pipelines. The method gets rid of shortcomings of the traditional analysis method of a laboratory without consuming chemical oxidizing agents, thereby having the advantages of convenient operation, simple and smart apparatus, simplified process and low cost, and realizing on-line continuous oxidization digestion, and being particularly suitable for water treatment of environmental water quality in an on-line continuous detection system.

Description

technical field [0001] The invention relates to a water sample oxidation and digestion device for on-line monitoring of water quality, in particular to an ultrasonic atomization high-voltage discharge combined with ozone ultraviolet oxidation and digestion device. Background technique [0002] The eutrophication of lakes and reservoirs is becoming more and more serious, which is closely related to the nitrogen and phosphorus content in the water. Excessive nitrogen and phosphorus content in water bodies will cause abnormal reproduction and growth of various aquatic plants. Large-scale cyanobacteria outbreaks have occurred in Taihu Lake, Chaohu Lake and other places. [0003] At present, the detection of the content of nitrogen, phosphorus and other substances in water samples mainly adopts the method of manual analysis in the laboratory: firstly, some oxidation and digestion method is selected to digest the organic matter, and the elements to be detected in various valence s...

AI Technical Summary

Problems solved by technology

The disadvantage is that the power consumption and electrode metal consumption are large when dealing with a large amount of wastewater, and the separated sediment is not easy to process and utilize.

At the same time, it will also produce metal cation interference in the solution, which is difficult to apply to water quality detection

[0013] In recent years, there have also been some new water quality analysis and testing equipment designed and manufactured using automation technology. They only add automation means to traditional laboratory analysis methods, such as automatic sampling, automatic sampling and analysis, etc. The core is still the traditional laboratory method, which requires regular addition of chemical reagents, is susceptible to interference, has poor stability, and cannot really be separated from manual work to achieve real-time online oxidation digestion
