Description

Digital display equipment for qualitatively and quantitatively detecting heavy metal pollutants in electroplating wastewater

Technical Field

The utility model relates to a digital display equipment of heavy metal pollutant, in particular to digital display equipment of heavy metal pollutant among qualitative quantitative determination electroplating effluent belongs to environmental protection, electroplating effluent treatment, heavy metal short-term test technical field.

Background

In the process of treating electroplating wastewater, qualitative and quantitative detection is needed for main pollutants such as heavy metal copper, nickel, hexavalent chromium, cyanide and the like, common detection modes include chemical analysis, instrument analysis, biological analysis and the like, wherein a colorimetric method is often used for rapidly and quantitatively detecting the pollutants in the electroplating wastewater at present, and the spectrophotometer also takes the colorimetric method as a basic principle.

The existing colorimetric method for detecting the pollutants in the electroplating wastewater mainly has the following defects:

(1) the existing colorimetric method has the following limitations in applicability: the photoelectric colorimetry and the spectrophotometry only adopt monochromatic light with one wavelength for one substance because of one photoelectric colorimeter or spectrophotometer, and carry out absorbance or transmittance detection on one sample, only one photoelectric colorimeter/spectrophotometer detector is used for detecting one substance in one sample at the same time, and the detection applicability of one photoelectric colorimeter/spectrophotometer detector for multiple substances in one sample, one substance in multiple samples and multiple substances in multiple samples is limited;

(2) the defects of manual detection are as follows: the visual colorimetry realizes colorimetry by means of visual observation, detection data are influenced by human factors, and the problems of high uncertainty, long operation time, high labor cost, incapability of batch detection and the like exist;

(3) the 1 detector can only detect the single index of a single sample: the existing colorimetric detection method can only detect 1 index of 1 sample generally, can not realize that 1 detector can detect a plurality of samples simultaneously, and can not realize detection of different indexes of different samples, different indexes of the same sample or the same index of different samples. When various pollutants need to be detected continuously in the sewage treatment process, the method is too long in time consumption and lags behind results.

(4) The defects of instrument detection and online automatic monitoring equipment detection are as follows: a. although the detection result error of instruments such as an atomic absorption instrument is very small, if manual detection is adopted, single indexes need to be calibrated one by one and operated one by one, the consumed time and the long-acting rate are low, and the detection time and the labor cost are too high; b. on-line monitoring instruments (automatic monitoring instruments) established on the basis of a photoelectric colorimetry and a spectrophotometry are also provided, because 1 photoelectric colorimeter or spectrophotometer is required to be correspondingly configured for detecting 1 index, the same on-line monitoring instrument cannot realize the detection functions of different indexes of different samples, different indexes of the same sample or the same index of different samples, and in order to realize the on-line automatic monitoring function, the on-line monitoring instrument has high requirements on the quality of equipment parts and the service capability of operation and maintenance personnel, and the cost performance of the on-line monitoring instrument is invisibly influenced, so that the on-line monitoring instrument cannot be popularized and used in daily sewage treatment operation;

the disadvantages of manual recording of colorimetric detection results: if the sampling amount, dilution multiple, colorimetric time and detection result of the sample are manually recorded, the random error of the recorded result is large, the probability of losing the record is high, and the chart analysis of each item of detection data cannot be performed in time.
