Residual chloride ion sensor-In the past two years, the emergence of a new type of coronavirus has severely disrupted people's lives. During the anti-epidemic process. Hospitals in various regions also produced a large amount of medical wastewater.
In order to ensure that the wastewater discharged by medical treatment meets safety indicators. The use of chlorine-containing disinfectants for disinfection treatment is a common and effective method in the treatment of medical wastewater.
At the same time, the control of disinfectants and the detection of residual chlorine content in the water environment are also very important in the process of medical wastewater disinfection treatment.
At this time, we can use the residual chlorine sensor in the water quality sensor to perform medical wastewater treatment. Water quality monitoring of residual chlorine content.
The state stipulates that if the medical wastewater disinfected with chlorine-containing disinfectants. Is to be directly discharged into nearby surface water or sea areas. Water quality monitoring is also required.
The total residual chlorine content in the medical wastewater should be less than 0.5mg/L. The disinfection process using residual chlorine disinfectants has also been clearly stipulated. The total residual chlorine content at the outlet of the contact pool for wastewater treatment of medical structures for patients with infectious diseases and tuberculosis is 6.5-10 mg/L.
For comprehensive medical institutions and For other medical structures, the discharge standard for the total residual chlorine at the outlet of the contact pool is 3-10 mg/L and the standard for the total residual chlorine at the outlet of the pretreatment disinfection contact pool is 2-8 mg/L.
Introduction of Residual Chloride Ion Sensor:
The residual chlorine sensor is a water quality sensor used to monitor the concentration of residual chlorine ions in water. The detection process is that the residual chlorine molecules in the measured aqueous solution pass through the selective penetration of the residual chlorine sensor to reach the cathode surface of the sensor.
When a polarization potential is applied. The residual chlorine molecules undergo a reduction reaction on the electrode surface of the water quality sensor. At the same time, the anode will undergo oxidation reaction to complete the entire oxidation-reduction reaction process.
The reaction process generates electric current, and the magnitude of the electric current generated is proportional to the residual chlorine content in the water. And the residual chlorine content is calculated by detecting the magnitude of the current.
