Scientific research on rare-metal new materials belongs to the high-end technology field. The wastewater generated in the experimental testing process has special composition and extremely high treatment difficulty, and is the focus and difficulty of environmental compliance management of high-end scientific research institutions. The National Innovation Center for Advanced Rare Metal Materials located in Xi'an, Shaanxi, as a national-level material R&D and pilot-testing core platform, carries out rare-metal physical and chemical analysis, performance testing and new material R&D on a daily basis. The wastewater is rich in rare-metal ions such as lithium, cobalt and titanium, strongly acidic digestion liquid and organic extractants, with complex pollutants and large concentration fluctuations.

In addition, regional environmental supervision is strict, and heavy-metal experimental waste liquid is classified as hazardous waste management, putting forward a zero-tolerance high standard for the purification accuracy and operation stability of wastewater treatment equipment. In order to thoroughly solve the problem of scientific research wastewater treatment and avoid environmental risks, the center newly introduced AiKe AK-SYFS-PJ series 1000 L/day integrated laboratory wastewater treatment equipment. The equipment adapts to the intermittent high-frequency drainage conditions of scientific research, and can efficiently treat complex rare-metal wastewater relying on an intelligent and precise control system. AiKe's engineer team went to the site to complete the full set of new installation, commissioning and technical delivery, and built a green compliance barrier for the national high-end material scientific research with professional equipment and standardized services.

I. Laboratory Wastewater Treatment Difficulties of the National Innovation Center for Advanced Rare Metal Materials

Located in Xi'an, Shaanxi, the National Innovation Center for Advanced Rare Metal Materials, as a national rare-metal material R&D and pilot-testing platform, faces industry-level challenges in laboratory wastewater treatment that far exceed ordinary scientific research institutions.

First, the wastewater components are extremely special. The center focuses on rare-metal and advanced material composition analysis, metallurgical performance testing and new material development. The wastewater generated during experiments contains rare-metal ions such as lithium, cobalt, titanium, lanthanum and cerium, as well as complex components such as strongly acidic digestion liquid and organic extractants. The pollutant concentration fluctuates sharply, and the requirements for the precise purification capability of the treatment equipment are much higher than general scenarios.

Second, the pressure of environmental compliance is prominent. Environmental supervision in Xi'an is increasingly strict. The laboratory-generated waste liquid containing heavy metals and hazardous characteristics is included in the HW49 category management of the 'National Hazardous Waste List'. Any substandard treatment or illegal discharge will face severe accountability, which puts forward zero-tolerance requirements for the stability and reliability of wastewater treatment equipment.

Third, the newly installed equipment must adapt to multi-dimensional matching needs. The center's daily treatment capacity reaches 1000 liters, belonging to a larger model of the PJ series. It must adapt to site conditions, meet the strict regulations that the pilot-test wastewater be comprehensively treated and not discharged externally, and at the same time the fully automatic operation mode needs to effectively respond to the realistic working conditions of high-frequency and intermittent experimental drainage, ensuring that scientific research progress and environmental compliance advance simultaneously.

II. AiKe Completes On-site New Installation of Equipment at Xi'an Rare-Metal Innovation Center

Recently, AiKe's engineering technical team rushed to the National Innovation Center for Advanced Rare Metal Materials in Xi'an, Shaanxi Province, to complete the on-site new installation, commissioning and technical delivery of the AK-SYFS-PJ series laboratory wastewater treatment equipment, building a compliant defense line for the wastewater discharge of rare-metal scientific research experiments.

The innovation center focuses on rare-metal new material R&D, physical and chemical analysis, performance testing and other core scientific research tasks. The experiment generates a large amount of comprehensive wastewater containing heavy metals, acid-base digestion liquid, inorganic salts and a small amount of organic solvents. The pollutant components are complex, and the equipment has high requirements for purification treatment capability. The newly installed equipment has a daily treatment capacity of 1000L, an integrated design, small footprint, and adopts a fully automatic operation mode, which can match the intermittent drainage conditions of scientific research laboratories.

After arriving at the site, the engineers completed equipment positioning, pipe connection and circuit layout, verified multiple purification treatment units item by item, carried out water-pass commissioning, and finely calibrated various operating parameters to ensure stable operation of the whole machine. At the same time, they conducted hands-on training for scientific research staff, explaining the equipment operation process and daily inspection points. After on-site sampling and testing, the outlet indicators met the relevant national wastewater discharge standards. AiKe's standardized on-site new installation and delivery service helps the rare-metal material scientific research project proceed in an orderly and green manner.

III. Introduction to AiKe AK-SYFS-PJ Series Laboratory Wastewater Treatment Equipment

AiKe's popular-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 the failure rate; the program reserves an upgrade interface, with a simple, direct, and visual interface.

AK-SYFS-PJ wastewater (sewage) treatment system features PLC fully-automatic control and a manual-interface human-intervention system. When the system fails during operation, manual enabling is performed. The upper part of the manual interface controls chemical treatment, while the lower part controls the operation of each process. Manual mode is used by AiKe engineers during commissioning and fault conditions, forcibly enabling a certain link of the system and adding fault-alarm prompt bars, making system faults clear at a glance and maintenance more direct and simple. It meets the relevant requirements in the national standards 《Integrated Wastewater Discharge Standard》(GB8978-1996), 《Water Pollutant Discharge Standard for Medical Organizations》(GB18466-2016), and 《Water Quality Standard for Sewage Discharged into Urban Sewers》(GB/T 31962-2015).
