Description

Technical Field

[0001] The present invention relates to the technical field of industrial wastewater pollutant detection, and in particular to a method and device for rapid detection of industrial wastewater pollutants. Background Art

[0002] Industrial wastewater pollutants refer to various suspended solids contained in wastewater, sewage and waste liquid generated in the industrial production process.

[0003] Currently, the detection of industrial wastewater pollutants is typically done chemically. These methods often require the addition of solvents to the wastewater for mixing, such as the addition of a specific color developer in spectrophotometry, followed by absorbance measurement using a spectrophotometer. Consequently, existing methods for detecting industrial wastewater pollutants are cumbersome and incapable of rapid detection, resulting in limitations. Therefore, a method and device for rapid detection of industrial wastewater pollutants are invented. Summary of the Invention

[0004] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0005] A method for rapid detection of industrial wastewater pollutants comprises the following specific steps:

[0006] Step 1: Place industrial wastewater in the test cylinder. Then, the weight of the industrial wastewater is recorded by the weight sensor. After recording, the wastewater will flow out through the first hard pipe. At this time, the pollutants in the industrial wastewater will be retained in the test cylinder due to the filter. During this process, the stepper motor will rotate the crossbar to be able to use the brush wire to knock away the pollutants attached to the filter, so as to prevent the pollutants from clogging the filter.

[0007] Step 2: The sealing plate is closed on the top of the detection cylinder by the first cylinder. Then, hot air is released into the detection cylinder by the fan and the electric heating wire to dry the residual wastewater on the detection cylinder and the pollutants. After drying, the sealing plate is restored to its original position. Then, the weight of the pollutants is recorded by the weight sensor. At this point, the pollutant concentration in the industrial wastewater can be obtained.

[0008] Step 3: The servo motor drives the movable rod to rotate the rotating shaft until the detection cylinder is on the left and the first hard tube is facing upward. After that, the second hard tube is inserted into the first hard tube through the second cylinder. Then, the water in the water tank is pumped into the detection cylinder. At this point, the inner cavity of the detection cylinder can be flushed, and the flushed water will fall on the water collecting tank.
