In biomedical R&D, laboratory wastewater treatment is a 'precision battle' of accuracy and safety rather than a volume game. A Wuhan tech firm focused on biomedical and new-material R&D generates only 50 L of wastewater daily, yet its mix of bioactive residues, organic synthesis intermediates and low-concentration acid-base buffers demands highly accurate inactivation and purification; any negligence may break compliance. With flexible project rhythms, discharge is irregular — sometimes none for days, then multiple batches centrally. This 'pulsed' discharge continuously tests the standby adaptability and instantaneous response of small-volume equipment.

Wuhan has high temperature and humidity in summer, and the equipment has been operating continuously for three years in a small corner of the R&D area. Hidden dangers such as pipe aging and sensor parameter deviation have gradually accumulated, while the core team of the enterprise focuses on R&D and lacks full-time operation and maintenance force, making it difficult to predict the equipment status.

Facing these challenges, the enterprise introduced AiKe AK-YLFS-XZH series micro small wastewater treatment system three years ago, continuously guarding the compliant discharge of every drop of wastewater in the limited space with fully automatic intelligent control and compact design.

I. Analysis of Laboratory Wastewater Treatment Difficulties

This technology company in Wuhan focuses on biomedical-related R&D business. The laboratory generates only 50L of extremely small-volume wastewater per day, but faces disposal difficulties far exceeding the conventional small-water-volume scenario.
First, the wastewater generated by R&D experiments is mixed with trace bioactive residues, organic synthesis intermediates and low-concentration acid-base buffer solution. The pollutant components are fine and some are bioactive. Conventional simple neutralization devices cannot achieve complete inactivation and deep purification, and a slight omission is difficult to meet the standards.
Second, the R&D project advancement rhythm is flexible, and wastewater discharge is completely adjusted according to the experiment progress without a fixed rule. Sometimes there is no wastewater output for several consecutive days, and sometimes multiple batches of different types of waste liquid are discharged centrally in a single day, which puts extremely high requirements on the standby adaptability and instantaneous treatment response speed of small-water-volume equipment.
Third, Wuhan has high temperature and humidity in summer, and the equipment is placed in a narrow space at the corner of the R&D area with limited ventilation. After 3 years of continuous use, hidden aging of pipes and electronic control components is prone to occur. However, the core team of the enterprise is concentrated in R&D posts and has no full-time operation and maintenance personnel, making it difficult to predict the potential operation hazards of small-water-volume equipment in advance, and prone to discharge compliance risks caused by small failures.

II. AiKe Goes to Wuhan Technology Enterprise for Free On-site Maintenance

Recently, AiKe's after-sales engineer team went to a technology company in Wuhan, Hubei Province, to provide free on-site maintenance services for the AK-YLFS-XZH series laboratory wastewater treatment equipment that has been in use for 3 years, ensuring the continuous and stable compliant discharge of the enterprise's R&D laboratory wastewater.

The enterprise mainly carries out new-material R&D and sample analysis and testing work. The laboratory produces wastewater containing acid-base reagents, trace heavy metals and organic waste liquid. The drainage frequency is scattered, belonging to the small-water-volume intermittent discharge condition. The maintenance equipment has a daily treatment capacity of 50L, is small and compact, adapts to the limited placement space of the enterprise laboratory, and has continuously undertaken R&D experimental wastewater treatment tasks for three years. The air humidity in Wuhan is high, and after long-term operation, the equipment is prone to aging hidden dangers such as filter material siltation and sensor parameter deviation.

On-site engineers comprehensively cleaned and repaired the core treatment units such as micro-electrolysis, oxidation adsorption and flocculation sedimentation of the equipment, checked the corrosion-resistant pipes, dosing pumps and PLC electronic control system, calibrated the water-quality sensing parameters, and investigated line safety hazards. At the same time, they provided hands-on guidance to the enterprise technicians, explaining the daily inspection points and simple fault identification methods. After maintenance, sampling and verification showed that all outlet indicators met the relevant national wastewater discharge standards. AiKe relies on the original on-site maintenance service to build an environmental compliance barrier for the enterprise's R&D work.

III. AiKe AK-YLFS-XZH Series Laboratory Wastewater Treatment Equipment Introduction

AiKe micro-type comprehensive wastewater (sewage) treatment system adopts the all-new AiKe sewage system V1 to precisely control the system, improving response time and accuracy while reducing failure rate; the program reserves upgrade interfaces, and the interface is simple, direct, and visual.

AK-YLFS-XZH wastewater (sewage) treatment system features PLC fully automatic control and a manual interface for human intervention; when the system fails, the operator can force-enable it. The upper half of the manual interface controls chemical treatment, and the lower half controls the operation of each process. Manual mode is used by AiKe engineers during commissioning and fault handling, allowing a certain link of the system to be forcibly enabled, adding fault alarm prompts so that system faults are clear at a glance and maintenance is more direct and simple. it meets the relevant requirements of the national Integrated Wastewater Discharge Standard (GB8978-1996), Discharge Standard of Water Pollutants for Medical Organizations (GB18466-2016), and Water Quality Standard for Wastewater Discharged into Urban Sewers (GB/T 31962-2015).
