Description
Technical field
This utility model relates to multi-parameter water quality on-line monitoring field, especially a kind of multi-parameter water quality on-line checking pen.
Background technology
Total dissolved solid (TDS) is defined as in water the total amount containing various dissolubility mineral saltses, TDS value represents solute impurity content in water, TDS value is the biggest, in water, solute impurity is the most, illustrate in water can the impurity content of conductive materials big, by detection total dissolved solid (TDS), the total salinity of water can be analyzed, electrode module described in the utility model predominantly detects the total solids content being dissolved in the water thus reaches to detect water quality, this module is indirectly to reflect TDS value by measurement electrical conductivity of water, the electric conductivity of water is the best, TDS value is the biggest, electrode uses the mode of direct current, directly power up and be pressed on probe the two poles of the earth, measure two interelectrode voltages, draw electrical conductivity, again by calculating the TDS value of water outlet.
COD (COD) is the leading indicator in environmental protection tests, COD and turbidity are surface water, important indicator in groundwater monitoring, when surface water is monitored, use traditional COD on-line detector of chemical colorimetry, volume is big, there is secondary pollution risk, be not suitable for earth's surface water monitoring, and can not well with turbidity, the monitoring parameter integration such as colourity, the absorption of specific wavelength ultraviolet light is followed Lambert-Beer's law by the organic contamination substrate concentration in water body, this shows that the absorbance of special wavelength light can be as the alternate parameter of Organic substance in water concentration, demarcated by specific, can be by the method to the COD in water, BDB, the indexs such as TOC detect.
nullTurbidimetry is according to international standard ISO07027 and EPA standard EPA180.1，Use 880nm light source，Utilize 90 degree of scattered light intensities to measure turbidity value，This monitoring method can accurately measure low concentration turbidity value，Traditional determination of colority uses platinum to bore colorimetry，The method uses and visually judges，Process is the most complicated，It is not suitable for on-line checking，Multiple studies have shown that，The chromatic value that the absorbance of 350nm-390nm and platinum brill colorimetry obtain has good dependency，Traditional UV double light path COD on-line detector，Typically use mercury lamp light source，The characteristics of luminescence of mercury lamp determines and 254nm spectrum can only be selected to carry out COD measurement，546nm spectrum is used to carry out determining amount，But at 254nm, measure COD，Owing to 254nm spectral absorption is excessive，Limit testing range，And 546nm is in visible light wave range，As determining amount，Can be disturbed by colourity，Affect the effect of determining amount.
