Problems solved by technology

[0003] Although a variety of detection methods and equipment for monitoring the quality of water have been successfully developed, due to too many types of pollutants in water, such as various microorganisms, viruses, bacteria, fungi, protozoa, algae, and various heavy metals soluble in water Salt, other water-soluble salts, various water-soluble organic compounds and volatile organic compounds, various suspended particles, nitrogen element substances, phosphorus element substances, radioactive substances, etc., can only judge the quality of water after completing many tests, and the speed is slow , and high cost

Embodiment 1

[0034] What this embodiment adopts is qualified water calibration method, such as figure 1As shown, the water storage tank 51 storing pure water with a resistivity of 18MΩ*cm (25°C) is used as the water source and qualified water, and the other sample water tank 52 is a water sample for adjusting the water quality and calibrating the monitor, 18MΩ *cm of pure water is prepared by adding corresponding pollutants. The two kinds of water can pass through a tee 5, and the pure water and sample water are sent to another storage tank through the water quality online monitor with a peristaltic pump, that is, two of the three-way 5 Two ports are respectively connected to the pure water storage tank 51 and the sample water tank 52, and the other port is connected to the online water quality monitor. When the water quality on-line monitor is calibrated, only pure water is transported in the pipeline 1, and the electric field induction area 3 uses a contact conductivity electrode, such a...

Embodiment 2

[0041] This embodiment is mainly used to verify the linear relationship between the concentration of pollutants in water and the data obtained by detection. Its method adopts the same parameters as in Embodiment 1 and the selection and use of samples, such as Figure 4 As shown, the figure shows the relationship between the total number of bacterial colonies in water and the measured absorbance, such as Figure 5 As shown, the figure shows the relationship between the concentration of sodium in water and the absorbance. It can be seen that there is a linear relationship between the concentration of pollutants in the water and the absorbance in the two figures, so that the online water quality monitor can monitor water quality better and faster.

Embodiment 3

[0043] This embodiment adopts qualified water comparison method to monitor. The water in the pure water storage tank with a resistivity of 18MΩ*cm (25°C) is used as the pure water for washing the test pipeline, and the water sample in the sample water tank is prepared by adding corresponding pollutants into pure water with a resistivity of 18MΩ*cm , transferred to a water storage tank with a peristaltic pump. The sample water tank and the pure water storage tank are also connected to the online monitor through a tee. The full-featured online water quality monitor of this embodiment is provided with a comparison pool 4, which is located in the UV-visible light sensing area 2, and is also located between the UV-visible light source 22 and the UV-visible light sensor 21. Every time the sample water is changed, at least 18MΩ*cm pure water is used in pipeline 1 to run alone for 15 minutes to ensure that the two tests do not interfere with each other. Pure water was used as a refe...

Abstract

A fully-functional online water quality monitor comprises a pipeline. The water inlet end of the pipeline is connected to an external water pipe, the pipeline is provided with an electric field inducing area and an ultraviolet visible light sensing area along the water flow direction, the electric field inducing area comprises a positive plate and a negative plate which are arranged in the pipeline parallelly and oppositely and extend along the water flow direction, and the ultraviolet visible light sensing area comprises an ultraviolet visible light sensor and an ultraviolet visible light source which are arranged on the outer side of the pipeline oppositely. The fully-functional online water quality monitor is capable of monitoring change of various pollutants in water accurately and rapidly and alarming in real time, and is simple in structure, easy to implement, low in cost, accurate in measurement and alarming and capable of measuring various pollutants in water simultaneously, so that fully-functional rapid monitoring is achieved.

Description

technical field [0001] The invention relates to a water quality monitoring instrument. Background technique [0002] The quality of water, especially the quality of tap water and purified water prepared by various equipment, is closely related to human's daily life and physical health. Due to various reasons such as industrial pollution, agricultural pollution, natural disasters, aging pipelines, human negligence, etc., pollutants will be introduced into tap water. Purified water, whether prepared by filtration, electrodialyser, ion exchanger, reverse osmosis, distillation, or other appropriate processing methods, will suffer from contamination of filter materials, power failure, saturation or aging of ion exchange resins, membrane Aging or deformation, pollution of distillation channels, human negligence, and other reasons lead to the impurity of pure water. Therefore, while continuously improving tap water and pure water purification technology and strengthening manageme...
