AiKe's after-sales operation and maintenance team went to Hezhou University in Guangxi, providing original free on-site special maintenance for the AK-SYFS-HW series 2-ton/day outdoor laboratory wastewater treatment equipment that had been running stably for 3 consecutive years. As an applied undergraduate university in the eastern Guangxi region, Hezhou University has long faced the challenge of wastewater treatment brought by the parallel track of teaching and research: the complex composition of multidisciplinary experimental wastewater, the high shock load formed by concentrated post-class discharge, and the hot, humid and rainy outdoor environment of the eastern Guangxi mountains, all pose multiple tests to the long-term operation of the equipment.

This maintenance carried out a full-process troubleshooting and calibration for the aging hidden dangers of three years of operation, and simultaneously conducted hands-on training for the school's part-time operation and maintenance personnel. Finally, through on-site sampling and testing, all outlet indicators were stably up to standard, effectively building a green research environmental bottom line for the university.

I. Parallel Teaching and Research, Multiple Regional Challenges in Wastewater Treatment — Analysis of Hezhou University Laboratory Wastewater Treatment Difficulties

As an important applied undergraduate university in the eastern Guangxi region, Hezhou University runs teaching experiments and scientific research practice in parallel, and its laboratory wastewater treatment has long faced multiple specific difficulties.

First, the school frequently conducts experiments in multiple disciplines such as chemistry, biology and food, generating wastewater mixed with acid-base reagents, heavy-metal salts, organic solvents and biological culture residues. The composition spans a wide range with obvious toxicity differences, making conventional single-process routes unable to achieve comprehensive purification.

Second, although the total daily discharge of 2 tons of wastewater is not large, the discharge time is concentrated after teaching experiments, showing intermittent and time-segment concentrated discharge characteristics, with high instantaneous shock load, placing high requirements on the equipment's water-volume regulation and anti-shock capability.

Third, Hezhou is located in the mountainous area of eastern Guangxi, with rainy and humid springs and hot and stuffy summers. Outdoor-installed equipment must withstand the test of high humidity and temperature differences for a long time. In addition, most laboratory operation and maintenance personnel are part-time teachers with relatively weak professional technical strength, and insufficient daily inspection and fault prediction capability further increases the difficulty of long-term stable operation.

II. AiKe Carries Out Free On-site Maintenance for Hezhou University's Laboratory Wastewater Equipment

Recently, AiKe's after-sales engineer team went to Hezhou University in Hezhou City, Guangxi Zhuang Autonomous Region, to provide free on-site maintenance for the AK-SYFS-HW series laboratory wastewater treatment equipment that has been in use for 3 years, ensuring the long-term stable compliant discharge of the university's teaching and research experimental wastewater.

The physical, chemical and biology laboratories of Hezhou University have heavy daily teaching and research tasks, and the experimental wastewater contains acid-base reagents, heavy-metal ions, organic solvents and biological culture residues, with large water-quality fluctuations. The maintenance equipment has a daily treatment capacity of 2 tons, belongs to the outdoor-adapted model, adapts to the hot, humid and rainy environment of the south, and has been running smoothly for three consecutive years, undertaking the comprehensive wastewater treatment work on campus.

On-site engineers carried out a comprehensive inspection and cleaning of the equipment's core purification modules, corrosion-resistant pipes, sedimentation and adsorption units and intelligent electronic control system, checked whether the pipes were silted or blocked, calibrated various operating parameters, and investigated aging hidden dangers brought by long-term operation. At the same time, they conducted hands-on training for the school's management personnel, explaining the key points of daily inspection. After maintenance, on-site sampling and testing showed that the outlet indicators met the relevant national wastewater discharge specifications.

With original on-site maintenance services, AiKe continuously builds an environmental defense line for university research and teaching, reduces equipment operation and maintenance risks, and supports the construction of green research on campus.
