However, the residual chlorine concentration meter cannot directly measure BrO-, NHCl, NH 2 Cl, NH2Br, etc. can only calculate the TRO content through the calculation relationship, but this calculation relationship cannot be established in fresh water and seawater media at the same time
The electrode method adopts the principle of electrochemistry, the cost is high, the electrode diaphragm is easily damaged and polluted, the service life is short, and the equipment maintenance is cumbersome; however, the online analyzer for residual oxides (TRO) in water based on the DPD method is not affected, and can Accurate, simple and rapid determination of TRO content

Abstract
The invention relates to an on-line analyzer for TRO (total residual oxidants) in water. The on-line analyzer mainly comprises a water sample tank, a glass cuvette, an illumination detection device, a reagent blending device, a reagent storage device group and an analysis control device, wherein the water sample tank is sequentially connected with the glass cuvette and the reagent blending device through pipelines; the illumination detection device is mounted on the side wall of the glass cuvette; a reagent inlet is formed in the reagent blending device, and a stop valve bank is mounted at the reagent inlet; a sampling valve is mounted between the water sample tank and the glass cuvette; a reagent pump is mounted between the glass cuvette and the reagent blending device; the analysis control device comprises a central controller and a control module. The analysis control device is used for continuous diagnosis, the content of TRO in water can be measured directly, accurately, conveniently and quickly, high pollution cost and pollution caused in an electrode method are avoided, equipment maintenance is simplified, and the on-line analyzer has a good industrial effect.
Description
technical field [0001] The invention relates to the field of detection of residual oxides in the water treatment process, in particular to an online analyzer for residual oxides in water, which is suitable for water treatment fields such as tap water, municipal and industrial wastewater, desalinated seawater, electrolyzed seawater, and ship ballast water. Detection of residual oxides in water quality. Background technique [0002] Today, with the rapid development of the global economy, while human beings continue to achieve rapid development, the impact on the environment is also increasing, and it is also increasing the difficulty of environmental governance. At the same time, the application of various oxidants and fungicides is also increasing. It is becoming more and more widespread, but it is also a double-edged sword. For example, a certain amount of residual chlorine is maintained in tap water to ensure the safety of microbial indicators in drinking water, but excee...
