The wastewater treatment of scientific research and testing laboratories in Northeast China has long faced multiple regional problems such as low-temperature climate, water-quality fluctuations and weak operation and maintenance. The Liaoning Testing Institute located in Shenyang, Liaoning, as a local comprehensive third-party testing institution, carries out material physical and chemical analysis, environmental sample testing and other businesses on a daily basis. The experimental wastewater contains trace heavy metals, acid-base waste liquid and organic reagents. Batch testing leads to large water-quality concentration fluctuations, and pollutant exceeding standards easily occurs under small-water-volume working conditions.

At the same time, Shenyang has long and severe winters. The low-temperature environment easily causes pipe freezing and reduces reagent activity, putting strict requirements on the cold resistance and stability of wastewater treatment equipment. In addition, the institution has no full-time operation and maintenance personnel, and the equipment needs to take into account the characteristics of easy operation, unattended operation and high adaptability. In order to thoroughly solve the problem of compliant discharge of laboratory wastewater, the institute newly introduced AiKe AK-SYFS-PJ series 100 L/day integrated laboratory wastewater treatment equipment. Relying on the targeted on-site installation and commissioning scheme and localized delivery service, AiKe precisely adapts to the low-temperature working conditions of Northeast China and the intermittent drainage and limited space of testing institutions, and helps scientific research and testing work achieve green compliance and efficient stable operation with professional installation, commissioning and hands-on training.

I. Analysis of Laboratory Wastewater Treatment Difficulties

The Liaoning Testing Institute located in Shenyang, Liaoning, as a local comprehensive third-party testing institution, undertakes material physical and chemical analysis, environmental sample testing and other businesses on a daily basis. Its laboratory wastewater treatment has distinct northeastern regional and industry-specific difficulties.
First, the testing business covers multi-category samples, and the wastewater is mixed with trace heavy-metal residues, acid-base digestion waste liquid and a small amount of organic reagents. The water quality fluctuates greatly among different testing batches. Under the small water volume of 100 L/day, the pollutant concentration is prone to periodic spikes, and conventional simple treatment equipment can hardly achieve stable and precise purification.

Second, Shenyang has long and cold winters. The equipment is installed in a semi-open auxiliary room of the laboratory. The low-temperature environment easily affects the reagent activity and pipe circulation, and puts special requirements on the low-temperature adaptability and pipe anti-freezing design of the newly installed equipment.
Third, the testing personnel in the institute have heavy tasks and no dedicated environmental operation and maintenance post. After the new equipment is put in place, the operation connection needs to be completed quickly to avoid small faults accumulating due to unfamiliarity with the equipment logic, affecting the compliance of daily testing business wastewater discharge.

II. Efficient Response, Professional Delivery — AiKe Engineers Go to Liaoning Testing Institute to Complete New Equipment Service

AiKe's engineering technical team rushed to Shenyang City, Liaoning Province, to complete the on-site installation, commissioning and delivery training of the newly installed AK-SYFS-PJ series laboratory wastewater treatment equipment for Liaoning Testing Institute, providing strong support for the compliant disposal of wastewater in scientific research and testing laboratories in Northeast China with efficient and professional services.

As an important regional testing and scientific research institution, Liaoning Testing Institute undertakes a large number of sample composition analysis and physical and chemical performance testing experiments on a daily basis. The experimental process generates mixed wastewater containing acid-base reagents, trace heavy-metal ions and organic solvents. Due to frequent laboratory operations, strong intermittent drainage and limited installation space, the equipment has clear requirements for compactness, automation and ready-to-use capability.

In view of the above situation, AiKe engineers combined with the on-site conditions to efficiently complete equipment positioning, pipe connection and circuit access, debugged the core treatment units item by item, and ensured the success of the water-pass commissioning of the equipment at one time. The equipment has a daily treatment capacity of 100 liters, adopts an integrated design, occupies less than 2 square meters, operates fully automatically without dedicated attendance, and can fully adapt to the actual situation of intermittent drainage and limited space of the institute's laboratory. After the equipment operated stably, engineers conducted on-site sampling and testing, and all outlet indicators met the relevant national wastewater discharge standards.

During the delivery process, the engineers also systematically conducted hands-on training for laboratory management personnel on daily operation procedures, basic inspection points and simple fault identification, helping users quickly master the equipment use skills. AiKe's standardized on-site installation service enables users to truly realize 'ready to use upon installation, safe discharge'.
