On the vast land of Xinjiang, energy exploration and testing are an important cornerstone supporting the national resource strategy, and laboratory wastewater treatment is an environmental checkpoint that cannot be ignored on this front. An energy company in Xinjiang has long undertaken core businesses such as oil and gas sample analysis and mineral composition testing. The laboratory generates only 50 liters of wastewater per day. Although the volume is small, it has the characteristics of high viscosity and high mineralization due to the mixture of oil and gas organic residues, trace heavy-metal ions and high-saline-alkali digestion waste liquid. Ordinary small-water-volume equipment is prone to pipe siltation and incomplete purification.

What is more tricky is that the plant is located in the remote suburbs. The winter is long and severe, and the equipment is placed in a semi-open experimental auxiliary room. The low temperature not only greatly reduces the reagent activity, but also may cause the risk of pipe freezing; while the surrounding operation and maintenance outlets are scarce, and the core components have gradually shown natural aging hidden dangers after three years of operation. Once a sudden failure occurs, technical support is difficult to arrive in time. Facing these compound challenges specific to the northwest cold region, the enterprise introduced AiKe AK-YLFS-XZH series micro small wastewater treatment system three years ago, and continuously guarded the compliant discharge of every drop of wastewater in the extreme environment with integrated compact design, fully automatic intelligent control and multiple safety protections. Recently, AiKe's after-sales engineers traveled thousands of kilometers to the site to carry out in-depth maintenance for this frontier 'veteran'.

I. Analysis of Laboratory Wastewater Treatment Difficulties

This energy enterprise located in Xinjiang undertakes core businesses such as physical and chemical analysis of energy exploration samples, oil product performance testing and environmental monitoring on a daily basis. The small-volume laboratory wastewater of only 50L per day faces multiple disposal difficulties specific to the northwest cold region.
First, the testing wastewater components are special, mixed with oil and gas organic residues, trace heavy-metal ions and high-saline-alkali digestion waste liquid. Some components have high viscosity and high mineralization. Ordinary small-water-volume treatment equipment is prone to pipe siltation and incomplete purification.
Second, the winter in Xinjiang is long and severe. The equipment is placed in a semi-open experimental auxiliary room of the plant. The low-temperature environment will greatly reduce the reagent activity and is prone to cause pipe freezing risk, putting extremely high requirements on the equipment's low-temperature adaptability and pipe anti-freezing design.

Third, the plant is located in the remote suburbs, far from the urban operation and maintenance outlets. The equipment has been in use for 3 years, and the core components have natural aging hidden dangers. However, the plant has few full-time environmental operation and maintenance personnel. Once the equipment fails suddenly, it is difficult to obtain technical support in the first time, and the requirements for the long-term operation stability and fault self-tolerance of the equipment are strict.

II. AiKe Goes to Xinjiang Energy Enterprise for Free On-site Maintenance of Laboratory Wastewater Equipment

Recently, AiKe's after-sales engineer team rushed to the Xinjiang Uygur Autonomous Region 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 at an energy company in Xinjiang, ensuring the compliant discharge of energy-testing laboratory wastewater.

The energy company's laboratory mainly carries out physical and chemical testing and analysis of oil, gas and mineral samples. The experimental wastewater contains acid-base digestion reagents, trace heavy-metal ions and organic solvents, and the discharge is intermittent. The maintenance equipment has a daily treatment capacity of 50L, is an integrated model, occupies a small footprint, adapts to the narrow placement environment of the laboratory, and has been operating continuously for three years, undertaking the laboratory testing wastewater treatment work. Xinjiang has large temperature differences between day and night and a dry climate, and the equipment is prone to problems such as filter material hardening and sensor drift after long-term operation.

On-site engineers disassembled and cleaned the core treatment units such as flocculation sedimentation and oxidation adsorption, checked the pipes, dosing components and intelligent electronic control system, calibrated operating parameters, and comprehensively investigated the equipment aging hidden dangers brought by the temperature difference. At the same time, they conducted on-site training for the enterprise operators, explaining the inspection and maintenance points of the equipment in the plateau arid environment. After maintenance, sampling and testing showed that the outlet indicators met the national wastewater discharge standards. AiKe builds an environmental compliance defense line for the scientific research and testing of border energy enterprises with professional original maintenance services.
