In the global industrialization wave, the oil industry's rapid development has been shadowed by the spread of oil-contaminated soil. Pollutants like petroleum hydrocarbons and heavy metals erode soil structure, disrupt ecological balance, and even threaten human health through food chains. As traditional remediation methods show limitations, Desen Environment's oil-contaminated soil washing equipment has emerged as a "game-changer" through its breakthrough technology.
Precision Targeting: Perfect Synergy of Solvents and Processes
The core advantage of Desen's washing equipment lies in its precision in oil contamination stripping. Using 特制 (specialized) chemical/biochemical solvents, these molecular "nanotech agents" penetrate micron-scale pores between soil particles. In a dynamic environment driven by gravity and hydraulic pressure, the solvents undergo directional adsorption and dissolution reactions with petroleum pollutants. For viscous heavy oil contamination, active components in the solvents reduce viscosity, "loosening" it from soil surfaces; for light oil, solvents quickly encapsulate oil molecules to form a stable dissolved system. This "targeted therapy" washing process—optimized through hundreds of lab simulations and field tests—maintains high removal efficiency against various petroleum pollutants.
Intelligent Brain: 5G and PLC Build a Smart Hub
The equipment's 5G intelligent modules and PLC control system revolutionize soil remediation operations. This smart system acts as the "neural network," monitoring over 200 core parameters 24/7—from washing liquid pH and internal pressure fluctuations to real-time soil flow. The material metering system ensures ≤0.5% precision, guaranteeing accurate dosing of every reagent. Through a remote monitoring platform, technicians use big data analysis to predict equipment status, detecting potential faults 48 hours in advance. For complex contamination scenarios, parameters can be adjusted remotely to maintain optimal efficiency.
Flexible Adaptability: Modular Design for Complex Scenarios
The integrated modular design gives Desen equipment "Transformer-like" adaptability. Composed of pretreatment, high-power scrubbing, intelligent sorting, and resource recycling modules, they connect via standardized interfaces. In large oil extraction sites, the feeding module can be expanded to increase soil processing; for chemical parks with heavy metal-oil composite contamination, the sorting module separates soil by particle size for targeted treatment. Mobile units access mountainous oil depots, avoiding secondary pollution from long-distance soil transportation. Compared to traditional equipment, Desen's on-site assembly time is reduced by 60%, significantly shortening project kick-off cycles.
Proven Performance: From Northwest Oilfields to Middle Eastern Deserts
1. Ningxia Changqing Oilfield Project
Facing 3-meter-deep soil with up to 15,000mg/kg petroleum hydrocarbons and heavy metal exceedances, Desen's equipment used a "hierarchical treatment + deep purification" strategy:
Cyclone sorting separated sandy soil to rapidly reduce pollutant 总量 (total volume).
Multi-stage washing with biological enhancement degraded persistent organics.
Final results: ≥92% petroleum hydrocarbon removal, heavy metal washing below national standards, and a 25% shorter remediation cycle than expected.
2. Abu Dhabi, UAE Project
Confronting calcium-rich sand and -5°C to 50°C desert temperatures, the team developed a "step-scrubbing + thermal desorption" process:
High-temperature steam assisted oil stripping.
Phase-change material temperature control maintained optimal component conditions.
Outcomes: 93.7% petroleum hydrocarbon removal, 88% sludge dewatering, restoring contaminated desert soil to ecological usability—setting an international remediation benchmark.
Green Closed Loop: Dual Breakthroughs in Environmental Protection and Economy
Desen's equipment implements a "zero discharge, full recycling" philosophy:
Wastewater treatment uses "MBR membrane bioreactor + advanced oxidation," achieving ≥95% COD removal; treated water is recycled for washing.
Exhaust gases pass through activated carbon adsorption-catalytic combustion, with ≥99% harmful gas removal.
Resource recycling extracts oil from oily sludge for refining. In one chemical site project, 1,200 tons of crude oil were recovered, generating over ¥8 million in economic benefits—truly realizing "remediate soil, create value."
As soil remediation enters an era of refinement and intelligence, Desen Environment's oil-contaminated soil washing equipment writes a new chapter in pollution governance through technological innovation and ecological responsibility. Whether for vast oilfields, industrial sites, or special geological areas, Desen provides customized solutions. Committed to safeguarding soil health and reshaping ecological futures, Desen welcomes partnerships to build a solid foundation for our green planet.
