Background
The water quality monitoring is a process of monitoring and measuring the types of pollutants in the water body, the concentration and the variation trend of various pollutants and evaluating the water quality condition. The water quality monitoring is a process of monitoring and measuring the types of pollutants in the water body, the concentrations and the variation trends of various pollutants and evaluating the water quality condition. The main monitoring items of water quality monitoring can be divided into two categories, one category is the comprehensive indexes reflecting the water quality conditions, such as temperature, chroma, turbidity, pH value, conductivity, suspended matters, dissolved oxygen, chemical oxygen demand, biological oxygen demand and the like; the other is some toxic substances, such as phenol, cyanogen, arsenic, lead, chromium, cadmium, mercury, organic pesticides and the like. In order to objectively evaluate the water quality of rivers and oceans, it is sometimes necessary to measure the flow velocity and flow rate in addition to the above-mentioned monitoring items.
Spectrophotometry is a method of qualitatively and quantitatively analyzing a substance to be measured by measuring the absorbance or luminous intensity of the substance at a specific wavelength or within a certain wavelength range. In a spectrophotometer, when light of different wavelengths is continuously irradiated to a sample solution of a certain concentration, absorption intensities corresponding to the different wavelengths can be obtained. If the wavelength (λ) is plotted on the abscissa and the absorption intensity (A) on the ordinate, the absorption spectrum of the substance can be plotted. The method of analyzing a substance qualitatively and quantitatively using this curve is called spectrophotometry, and also called absorption spectroscopy. A method of measuring a colorless substance with an ultraviolet light source, which is called ultraviolet spectrophotometry; the method of measuring colored substances using a visible light source is called visible light photometry. They are based on the Lambert-Beer law, as are colorimetry. The above-mentioned ultraviolet and visible light regions are commonly used. However, the applied light region of the spectrophotometry method includes an ultraviolet light region, a visible light region and an infrared light region. An ultraviolet spectrophotometer, a visible spectrophotometer (or colorimeter), an infrared spectrophotometer, or an atomic absorption spectrophotometer.
In the prior art, the upper part of a meter is communicated with a peristaltic pump, the lower part of the meter is communicated with a multi-way valve, two light source detectors on the meter are respectively connected with a controller, and the controller controls the positive and negative rotation of the peristaltic pump to realize liquid pumping or liquid pressing. The controller controls the emitter of the light source detector to emit light source to pass through the metering glass tube, and then the light source is received by the receiver of the light source detector and sent to the controller for processing. The higher the concentricity of the emitter, the receiver and the metering glass tube of the light source detector is, the better the detection effect is. The metering device and the multi-way valve need to be connected through a conversion head, so that air leakage and dislocation are easily caused, and the metering accuracy is not facilitated.
The metering device for the water quality monitor has the advantages of compact structure, small volume, multi-way valve integration, high light source concentricity, metering preparation degree improvement and manual labor reduction.
