Description

Technical Field

[0001] The utility model relates to the technical field of heavy metal ion detection, in particular to a real-time detection device for heavy metal ions in sewage. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater is of various types and complex composition, containing various heavy metals. Direct discharge not only pollutes the environment, but also has great harm to human health. Therefore, it is necessary to take corresponding purification measures to dispose of it. However, in order to facilitate the treatment of heavy metal wastewater, it is often necessary to detect heavy metals in wastewater.

[0003] The existing patent (application number 201610414857.7) discloses a fiber optic sensing device for heavy metal ion detection, including: a light source module, a wavelength division multiplexer, a first fiber optic coupler, a transmission fiber optic, a second fiber optic coupler, a detection fiber optic, a signal demodulation device, a wireless transmission device, and a host computer. It is used to monitor heavy metal ions in water on-site and in real time by combining quantum dots with optical fibers on the detection fiber optic. It combines metal nanoparticle enhanced fluorescence technology with optical fibers and quantum dots to detect a variety of heavy metal ions; it is used to send the heavy metal ions detected by the signal modulation device to the host computer in real time by setting a wireless transmission device and a host computer, which is convenient for management personnel to view and monitor.

[0004] The above patent forms a stable fluorescent fiber optic probe by combining quantum dots with optical fibers on the detection optical fiber, which can be used for on-site and real-time monitoring of heavy metal ions in water. The metal nanoparticle enhanced fluorescence technology is combined with optical fibers and quantum dots to detect a variety of heavy metal ions with high sensitivity and accuracy. However, the fluorescent fiber optic probe directly penetrates into the sewage for detection, which is not only susceptible to scratches and collisions from large particles of impurities in the sewage, affecting its service life; in addition, the fluorescent fiber optic probe is not well stored after use, which makes it inconvenient to carry.
