The R&D experimental wastewater of the new material industry has complex components and high treatment difficulty, which is the focus and difficulty of industrial environmental protection control. A new material enterprise located in Beihai City, Guangxi, deeply cultivates the R&D and testing of polymer materials and functional composite materials. The experiment produces an average of 1000 L of laboratory wastewater per day. The industry-specific pollution characteristics superimposed with the special coastal climate make wastewater governance face multiple technical problems.

The enterprise's R&D wastewater is a typical composite polluted water body, mixed with refractory organic solvents, polymer intermediates, heavy-metal ions and nano suspended particles. The COD concentration is high and biodegradability is poor. Moreover, the experiment project iterates quickly and the water quality fluctuates strongly, which is difficult for conventional treatment equipment to stably adapt to. At the same time, Beihai is located on the coast of the Beibu Gulf, with high temperature, high humidity and salt fog enrichment all year round, which easily causes the electrical control of the equipment to be damp, the body to corrode and the pipeline to scale, seriously affecting the operation stability of the equipment. To thoroughly solve the operation and maintenance pain points of coastal working conditions and overcome the new material wastewater governance problem, and ensure the long-term stable compliant discharge of the enterprise's experimental wastewater, AiKe's operation and maintenance engineers made a special trip to the site to provide a full-range free special maintenance service for the enterprise's AK-SYFS-SD-1000 laboratory wastewater treatment equipment.

I. The Composite Pollution and Process Adaptation Problem of New Material Enterprise Laboratory Wastewater Treatment

A new material enterprise in Beihai City, Guangxi Zhuang Autonomous Region focuses on the R&D and testing of new polymer materials, functional composite materials and electronic chemicals. Its 1000 L/day laboratory wastewater carries the complex pollution challenges unique to the new material industry, and the treatment difficulty far exceeds that of ordinary industrial laboratories.

First, the organic pollutants in the wastewater present the coexistence of 'high concentration' and 'diversification'-various monomers, initiators, crosslinking agents and organic solvents remaining in polymer synthesis experiments are mixed with plasticizers, flame retardants and other additives used in material performance testing. The chemical oxygen demand (COD) concentration can be as high as tens of thousands of mg/L, and some polymer intermediates have biological inhibition or refractory characteristics, which conventional biochemical treatment systems can hardly establish stable degradation efficiency. At the same time, new material R&D involves a variety of precious metal catalysts and functional fillers. The waste liquid may contain heavy-metal ions such as silver, palladium, copper and chromium and nanoparticles, forming a 'high-concentration organic matter-heavy metal-suspended particles' trinity composite pollution system, which places extremely strict requirements on the combination integrity of the treatment process chain.

In addition, Beihai is located on the south China coast, with a subtropical marine monsoon climate, warm and humid all year round, and relative humidity is often high. The electrical control system of the equipment faces severe moisture and corrosion tests. Coupled with the high salt fog content in the coastal air, it puts extra pressure on the corrosion resistance of the metal structural parts of the equipment. The new material industry has fast product iteration and frequent experiment project changes. The wastewater quality shows obvious stage drift with the adjustment of R&D direction, which further aggravates the difficulty of process adaptation and dynamic optimization of operating parameters of the treatment system, and becomes the core technical bottleneck restricting the enterprise's environmental compliance.

II. AiKe AK-SYFS-SD-1000 Completes Free On-Site Maintenance for Beihai Enterprise

AiKe's operation and maintenance engineering team rushed to a new material enterprise in Tieshangang District, Beihai City, Guangxi Zhuang Autonomous Region, and completed a full-process on-site free special maintenance for the AK-SYFS-SD-1000 laboratory wastewater treatment equipment in operation on site, thoroughly eliminating the wear and tear hidden dangers generated by long-term operation of the equipment under the high-humidity and high-salt environment of the Beibu Gulf, and building a compliance defense line for the laboratory wastewater disposal in the new material R&D scenario.

The enterprise is located in the Beibu Gulf new material industry cluster belt. The laboratory routinely undertakes core work such as new material component analysis and R&D sample physical and chemical testing. The 1000 L/day wastewater mixes high-concentration salts, heavy-metal residues and refractory organic pollutants, with large water-quality fluctuations and high treatment difficulty. Coupled with the special working conditions of high temperature and high humidity along the Beihai coast, after long-term operation, problems such as pipeline scaling, dosing deviation and electrical control components being damp are prone to occur. This maintenance targeted the completion of pipeline dredging and cleaning, heavy-metal capture system calibration, online monitoring instrument calibration, whole-machine moisture-proof safety inspection and other full-link operations, and all operating parameters have been fully restored to factory standards.

At present, the equipment effluent stably meets relevant national discharge standards. The original-factory on-site maintenance greatly reduces the operation and maintenance pressure of new material enterprises, and builds a long-term reliable closed-loop governance system for laboratory wastewater in the coastal industrial scenario of the Beibu Gulf.
