AiKe's original after-sales operation and maintenance team went to Beijing to provide free on-site special maintenance services for the AK-YLFS-XZH series 100 L/day medical laboratory wastewater treatment equipment that has been running smoothly for 2 years at Luhe Hospital Affiliated to Capital Medical University. As a large tertiary comprehensive hospital integrating medical care, teaching and scientific research, the wastewater of the hospital's testing and microbiology departments has dual attributes of medical and scientific research. It not only contains pathogenic microorganisms and clinical sample pollutants, but also is mixed with trace heavy metals, acid-base reagents and organic residues generated in the testing process, and the disposal standard is much higher than ordinary scenarios.

This maintenance focused on the in-depth investigation and calibration of the disinfection and inactivation unit in the medical scenario, cleaned up the hidden dangers of filter material siltation caused by two years of operation, and simultaneously conducted special operation training for the department's operation and maintenance personnel. After on-site sampling and verification, the effluent fully met the relevant requirements of the 'Discharge Standard of Water Pollutants for Medical Institutions', and effectively built a biosafety defense line for the hospital laboratory wastewater disposal.

I. Laboratory Wastewater Treatment Difficulties of Luhe Hospital Affiliated to Capital Medical University

As a large tertiary comprehensive hospital integrating medical care, teaching and scientific research, Luhe Hospital Affiliated to Capital Medical University generates wastewater from its testing, microbiology and scientific research laboratories with dual characteristics of medical and scientific research wastewater, and the treatment difficulties are particularly prominent.

First, the biosafety risk is high. The microbiology and immunology departments of the testing department involve the detection of third-class pathogenic microorganisms. The wastewater may be contaminated by patients' blood, urine and feces or infected by infectious bacteria, viruses and insect eggs and other pathogenic microorganisms, which is infectious. Once the disinfection is not thorough, it may induce diseases or cause environmental hazards. The pathogenic microorganisms in the wastewater must be strictly inactivated, and the equipment has extremely high requirements for the accuracy of disinfection and inactivation.

Second, the wastewater composition is complex and diverse. The laboratory-generated wastewater not only contains pathogenic microorganisms, but also is mixed with acid-base reagents, heavy-metal ions (heavy-metal residues such as mercury involved in testing), organic solvents and disinfectant residues. According to the 'National Hazardous Waste List', some components of such waste liquid belong to the category of hazardous waste, and the disposal standard is strict.

Third, the drainage law is extremely unstable. The hospital laboratory has a daily treatment capacity of only 100 liters, but the frequency of scientific research experiments and clinical testing fluctuates with the diagnosis and treatment needs, and the drainage shows the characteristics of strong intermittence and uncertain instantaneous shocks, which constitutes a continuous test on the small-water-volume adaptability and rapid response capability of the equipment.

II. AiKe Provides Free On-site Maintenance for Luhe Hospital Affiliated to Capital Medical University

Recently, AiKe's after-sales engineer team went to Beijing to provide free on-site maintenance services for the AK-YLFS-XZH series laboratory wastewater treatment equipment that has been in use for 2 years at Luhe Hospital Affiliated to Capital Medical University, ensuring the safe and compliant disposal of the hospital's testing laboratory wastewater.

The testing department of the hospital undertakes a large number of clinical sample testing tasks on a daily basis. The laboratory wastewater has special composition, containing acid-base reagents, trace heavy metals, organic reagents and pathogenic microorganisms. The wastewater discharge is characterized by intermittence and high requirements for the equipment's disinfection, purification and shock-resistance capabilities. The maintenance equipment has a daily treatment capacity of 100L, is small and integrated, adapts to the narrow placement space of the hospital laboratory, and has continuously disposed of the experimental wastewater generated by testing and analysis for two years.

After two years of continuous operation, the equipment has potential aging hidden dangers such as filter material siltation and electronic control parameter deviation. On-site engineers comprehensively repaired and cleaned the disinfection unit, flocculation sedimentation module, corrosion-resistant pipes and intelligent electronic control system, calibrated various operating parameters, and investigated safety hazards. At the same time, they conducted hands-on training for the hospital department personnel, explaining the key points of daily inspection and basic maintenance. After maintenance, sampling and testing showed that the outlet indicators met the relevant requirements of the 'Discharge Standard of Water Pollutants for Medical Institutions'. AiKe guards the environmental safety of medical institution laboratories with original on-site maintenance services.
