For a third-party environmental-testing institution, laboratory wastewater treatment is both the basic norm of internal operation and an industry bottom line tied to corporate credibility. An environmental-protection company in Pinghu, Zhejiang undertakes daily physical/chemical analysis and pollutant screening of water and soil samples from surrounding enterprises, generating about 1.5 tons of high-difficulty wastewater (heavy-metal chelated waste liquid, organic solvents, acid-base reagents). Facing dual pressures — highly uncertain wastewater composition and stringent discharge compliance under direct environmental supervision — the company relies on AiKe AK-SYFS-HW for all-weather stable operation.

In response to these stringent requirements, the enterprise introduced AiKe AK-SYFS-HW series outdoor weather-resistant laboratory wastewater treatment equipment two years ago, realizing all-weather stable operation with modular integrated process and fully automatic intelligent control. On the occasion of the second anniversary of the equipment's commissioning, AiKe's after-sales team went to Pinghu to carry out in-depth maintenance, safeguarding the compliance bottom line of this environmental-protection benchmark enterprise with professional services.

I. Analysis of Laboratory Wastewater Treatment Difficulties

As a local third-party environmental-testing service institution in Pinghu City, Zhejiang, this environmental-protection company undertakes the physical and chemical analysis and pollutant screening of water and soil samples from surrounding enterprises on a daily basis, and its laboratory wastewater treatment has difficulties distinct from ordinary colleges and universities.
First, the wastewater composition is complex and highly uncertain. The daily testing process generates a variety of high-difficulty treatment components such as acid-base reagents, heavy-metal chelated waste liquid, organic extraction solvents and trace persistent pollutant residues. The pollutant types and concentration of different batches fluctuate greatly, and conventional fixed-process equipment can hardly continuously adapt.

Second, the testing business operates at full capacity all year round, and there is no obvious off-season for wastewater discharge. The daily treatment volume of 1.5 tons is continuously and stably output, and the equipment is in a high-load continuous operation state for a long time, which puts extremely high requirements on the wear resistance and corrosion resistance of core components.
Third, the enterprise itself is mainly engaged in environmental protection, and its internal wastewater discharge compliance standard is stricter than that of ordinary units. Located in Pinghu Industrial Park and directly supervised by the environmental protection department, once the equipment operation fluctuates, it may trigger compliance risks, and the timeliness and professionalism of operation and maintenance are required to be much higher than ordinary scenarios.

II. AiKe Goes to Pinghu City to Provide Free On-site Maintenance for the Environmental-Protection Enterprise

AiKe's after-sales engineer team came to Pinghu City, Jiaxing City, Zhejiang Province, to provide free on-site maintenance services for the AK-SYFS-HW series laboratory wastewater treatment equipment that has been in use for 2 years by the environmental-protection company in Zhejiang, ensuring the stable and compliant discharge of the testing laboratory wastewater.

The laboratory of this environmental-protection company undertakes businesses such as environmental sample testing and pollutant analysis. The experimental wastewater has complex composition, containing acid-base reagents, heavy-metal ions and various organic pollutants, with large water-quality fluctuations. The maintenance equipment has a daily treatment capacity of 1.5 tons, belongs to the outdoor weather-resistant model, adapts to the rainy and humid climate of the Jiangnan region, and has continuously undertaken the comprehensive wastewater disposal tasks of the laboratory for two years.

On-site engineers carried out a comprehensive inspection and cleaning of the equipment's core purification units, corrosion-resistant pipes, sedimentation and adsorption modules and PLC intelligent electronic control system, dredged pipe deposits, calibrated operating parameters, and investigated the component aging hidden dangers brought by the humid environment. At the same time, they provided hands-on guidance to the enterprise operators and popularized the key points of daily inspection and maintenance. After maintenance, on-site sampling and verification showed that all outlet indicators met the relevant national wastewater discharge standards.

With original on-site maintenance services, AiKe helps environmental-testing enterprises build an environmental bottom line and escorts the green operation of third-party testing laboratories.
