Deeply cultivate medical wastewater monitoring! The combination scheme of residual chlorine and COD in Botuo instruments has been implemented in multiple hospitals in Ningxia

June 2025, Ningxia NewsIn response to the strengthened regulatory requirements of the "Discharge Standards for Water Pollutants in Medical Institutions" (GB 18466-2020), Shanghai Botuo Instrument has customized services for five tertiary hospitals in Ningxia Hui Autonomous Region“Combination scheme of residual chlorine and COD online monitoring”To achieve full process water quality monitoring of medical wastewater treatment.

The core equipment of this plan includesCLG-2059 residual chlorine analyzerandCOD-3000 online monitoring deviceThe residual chlorine analyzer adoptselectrochemical methodThe measurement range is 0-10mg/L, supporting synchronous monitoring of free chlorine and compound chlorine in medical wastewater; The COD monitor adopts the potassium dichromate oxidation method, with a detection time of ≤ 20 minutes and an instrument stability error of ≤± 2%/24h. The two sets of equipment can automatically identify abnormalities in the disinfection process (such as sudden decrease in residual chlorine and COD exceeding the standard) through data fusion algorithms, and trigger a three-level warning mechanism.

The composition of medical wastewater is complex, and traditional manual testing is prone to data lag. "The project leader stated that after the implementation of this plan, the operation and maintenance efficiency of hospital wastewater treatment facilities has been improved by 40%, and the annual cost of environmental violations has been reduced by about 800000 yuan. At present, the medical wastewater monitoring program of Botuo Instrument has covered more than 20 provinces across the country, serving over 300 medical institutions.
