Description
Technical Field
The invention relates to the field of water quality detection, in particular to a multi-parameter water quality detector and a detection method thereof.
Background
For water quality detection, various parameters are usually required to be detected, such as COD, BOD, ammonia nitrogen, total phosphorus, total nitrogen, temperature, pH value, conductivity, dissolved oxygen, turbidity and other conventional characteristic parameters in water. COD defines chemical oxygen demand, which is the amount of oxidant required for the oxidative decomposition of reducing substances in water under certain stringent conditions, expressed in mg/L of oxygen, and reflects the degree of pollution of the water by the reducing substances. BOD (Biochemical Oxygen demand): biochemical oxygen demand orBiochemical oxygen consumption is a comprehensive indicator of the content of aerobic pollutants such as organic matters in water. It shows that the organic matters in the water are oxidized and decomposed by the action of microorganisms, so that the total amount of dissolved oxygen in the water is consumed during mineralization or gasification. Ammonia nitrogen refers to free ammonia (NH) in water3) And ammonium ion (NH)4 +) Nitrogen in the form present. The nitrogen content of the animal organic matter is generally higher than that of the plant organic matter. The total phosphorus is the result of the determination after various forms of phosphorus are converted into orthophosphate by digestion of a water sample, and is measured by the mg of phosphorus contained in each liter of water sample. The pH value represents the degree of acidity or alkalinity of the aqueous solution. Conductivity is a tensor, which is the ability of a solution to conduct current in a digital representation in water quality testing. The content of dissolved oxygen in water has close relation with the partial pressure of oxygen in air and the temperature of water, and the amount of dissolved oxygen in water is an index for measuring the self-purification capacity of water. Turbidity is the degree of obstruction that occurs when suspended matter in water passes through to light.
The detection of parameters such as COD, BOD, ammonia nitrogen, total phosphorus, total nitrogen and the like can be carried out by a spectrophotometer, and the conditions of the absorption or emission spectrum wavelength, intensity, polarization state and the like of substance molecules under different conditions have inherent relation with the structural characteristics of the substance. Different substances differ in their molecular structure, corresponding to different absorption and emission spectra; when the concentration of the same substance is different, the absorption intensity at the same absorption peak position is different. Therefore, the concentration of a substance in water can be determined by detecting the degree of absorption of the substance in water to light of a particular wavelength. In the water quality detection, corresponding reagents are required to be dripped and then pretreated, and at the moment, water quality samples and the reagents need to be measured accurately and quantitatively, so that a more accurate detection result can be obtained. In addition, a water quality detector can only detect one characteristic parameter of a water sample at present, so that a plurality of water quality detectors are needed for detecting a plurality of characteristic parameters of water quality.
