Chlorine dioxide detection device of tap water quality

Abstract

The invention relates to a chlorine dioxide detection device of tap water quality. Structurally, the chlorine dioxide detection device comprises six units: water injection drive unit, a chlorine dioxide detection unit, an LED constant current source circuit unit, a magnetic agitation unit, a reagent injection drive unit, and a microprocessor control unit, wherein the microprocessor control unit isconnected with the water injection drive unit, the chlorine dioxide detection unit, the LED constant current source circuit unit, the magnetic agitation unit, and the reagent injection drive unit, the microprocessor control unit is used for controlling the whole system to work and completing wireless uploading of detection data. The chlorine dioxide detection device based on an illumination principle can be installed at the end of a water pipe network, and the microprocessor control unit circularly detects light absorption amount of illuminated liquid so as to detect residual chlorine dioxidein to-be-tested water online, and can realize constant online detection.

Description

technical field [0001] The invention belongs to the field of tap water quality evaluation, is applied to the detection of tap water quality, and particularly relates to a tap water quality chlorine dioxide detection device. Background technique [0002] Liquid chlorine disinfection of tap water is a tap water treatment technology widely used in my country at present, but it is inevitable that liquid chlorine disinfection of drinking water will produce carcinogenic and mutagenic substances. [0003] In order to control these harmful substances and improve the chemical safety of drinking water, many countries in the world have introduced ozone and chlorine dioxide water treatment technologies. Ozone treatment technology has small residues, but the cost is relatively high. At present, my country cannot fully promote ozone disinfection. Chlorine dioxide water treatment technology is currently the best choice for tap water disinfection in my country in terms of oxidation and sta...

AI Technical Summary

Problems solved by technology

[0004] At this stage, due to the process and cost of tap water production in my country, in the process of chlorine dioxide water treatment, it is inevitable that there will be problems such as excessive chlorine dioxide content, which will affect the quality of tap water.

As far as my country’s current routine testing methods for chlorine dioxide in tap water quality are concerned, it is mainly a third-party sample inspection of tap water plants, which cannot achieve real-time online and long-term continuous testing.
