AiKe's senior operation and maintenance engineering team made a special trip to an energy and chemical enterprise in Shenzhen, Guangdong Province, to complete a full-process on-site free special maintenance for the in-service AK-SYFS-SD-3000 large laboratory wastewater treatment equipment, thoroughly eliminating various hidden dangers accumulated during long-term high-load operation. All operating parameters have been fully calibrated and restored to the optimal factory standards, building the core barrier for the stable and compliant disposal of 3-ton large-volume laboratory wastewater in the energy and chemical scenario along the south China coast.

The enterprise's laboratory routinely undertakes core scientific research tasks such as oil product quality testing, chemical intermediate analysis and environmental monitoring. The wastewater contains total petroleum hydrocarbons, high-concentration salts and refractory organic pollutants coexisting. Coupled with the special working conditions of high temperature and high humidity in coastal Shenzhen, this places far stricter requirements on the corrosion resistance, electrical control reliability and deep pollutant removal efficiency of the large-volume wastewater treatment system than ordinary scenarios. This targeted maintenance simultaneously completed the practical training of the enterprise's operation and maintenance personnel, greatly reducing the operational risk of subsequent long-term stable operation.

I. The High-Salt High-Toxicity Governance Dilemma of Energy and Chemical Enterprise Laboratory Wastewater

As an important cluster of China's energy and chemical industry, Shenzhen is home to an energy and chemical enterprise whose laboratory undertakes key tasks such as oil product quality testing, additive performance evaluation, chemical intermediate analysis and environmental monitoring. The 3-ton/day wastewater concentrates the high-difficulty pollution spectrum unique to the energy and chemical industry, and the governance challenge far exceeds that of conventional laboratory wastewater.

First, the organic pollutant concentration in the wastewater is extremely high and complex, with total petroleum hydrocarbons, polycyclic aromatic hydrocarbons, benzene series and various organic extraction solvents mixed together. The chemical oxygen demand (COD) is often in the high range of tens of thousands of mg/L, and some organic matter is biologically toxic or refractory, which conventional biochemical treatment systems can hardly effectively cope with under such high-load shocks. Second, oil product and chemical product testing extensively uses strong-acid digestion, solvent extraction and other pretreatment processes. The waste liquid retains high-concentration acid-base and chlorides, sulfides, resulting in a significant increase in water salinity (TDS). The high-salt environment has an obvious inhibitory effect on microbial activity, greatly increasing the operation difficulty and system fragility of the biochemical treatment section.

In addition, Shenzhen is located on the south China coast, with high temperature and humidity all year round. If the ventilation and dehumidification measures of the equipment room are insufficient, the electrical control system is easily affected by moisture and causes failures, affecting the reliability of all-weather automatic operation of the equipment. At the same time, the 3-ton/day treatment volume is already a large scale in the field of laboratory wastewater governance, placing far stricter requirements on the integrity of the treatment process chain, the synergy efficiency of each unit module and the long-term stable compliance capability of effluent than small-water-volume equipment. The performance decay of any link may lead to insufficient system treatment margin.

II. AiKe On-Site Maintenance | Empowering Shenzhen Energy and Chemical Enterprise Laboratory Wastewater Standardized Disposal

AiKe's operation and maintenance engineers went to an energy and chemical enterprise in Shenzhen, Guangdong Province to carry out on-site free special maintenance services for the AK-SYFS-SD-3000 laboratory wastewater treatment equipment. The equipment has a daily treatment capacity of 3T, building a safety barrier for the enterprise's chemical testing laboratory wastewater treatment.

The energy and chemical enterprise laboratory undertakes raw material analysis, product physical and chemical testing, environmental sample testing and other work. The wastewater contains various chemical organic solvents, heavy-metal ions, acid-base digestion waste liquid, with complex pollutant components, strong toxicity and large water-quality fluctuations, placing high requirements on the equipment's corrosion resistance and comprehensive pollutant removal capability. Shenzhen is located on the southern coast, with high air humidity. The electrical control components of the equipment are easily affected by moisture. Long-term high-load operation is prone to pipeline scaling, dosing metering deviation and sensor drift.

This maintenance comprehensively overhauled and calibrated the equipment's pretreatment unit, dosing system, online monitoring instruments and electrical control protection module, investigated hidden dangers such as pipeline blockage and component aging, restored all operating parameters to factory standards, and conducted daily operation and maintenance practical training for the enterprise's operators.

The AK-SYFS-XZH-3000 equipment operates in fully automatic integrated mode, and the effluent meets relevant national discharge standards. The original-factory on-site maintenance effectively reduces the enterprise's operation and maintenance pressure, ensures the stable compliant discharge of chemical laboratory wastewater, and helps energy and chemical enterprises achieve the coordinated development of scientific research production and ecological environmental protection.
