Desen soil remediation equipment: helping the "battle to protect clean land"

With the deepening of the "Action Plan for Soil Pollution Prevention and Control", the "Battle for Clean Soil" has risen to a strategic priority for the construction of national ecological civilization. The 2025 Government Work Report clearly proposed "coordinated promotion of carbon reduction, pollution reduction and green growth", requiring higher standards to ensure soil environmental safety. Data show that there are more than 300,000 industrial polluted plots in my country, with a total amount of polluted soil exceeding 2 billion cubic meters, and the demand for governance continues to rise. Against this background, Zhengzhou Desen Environment relies on its independent innovation technology system to build a matrix of pollution control equipment covering heavy metals, organic matter, petroleum hydrocarbons and other types, providing scientific and technological support for protecting land safety.
Desen Environment focuses on technical breakthroughs in the field of soil remediation, and develops solutions that are both efficient, economical and eco-friendly for industry pain points.
Technological innovation: solving the problem of complex pollution control
Facing the problem of heavy metal and organic compound pollution, which accounts for up to 65% of chemical and mining plots, Desen Environment's independently developed integrated soil washing system achieves precise governance through the three-level collaborative process of "physical screening-chemical washing-water circulation". The system uses chelation enhancement technology to make the removal rate of heavy metals such as lead and cadmium exceed 95%. The intelligent dosing system can increase the degradation rate of polychlorinated biphenyls to more than 90%. The modular design supports rapid transfer operations, and the daily processing capacity of a single machine reaches 240 tons. In a lead-zinc mine remediation project in Hunan, this technology completed the remediation of 26,000 cubic meters of contaminated soil in just 45 days, saving more than 8 million yuan in external transportation and disposal costs. The soil indicators after remediation fully met the safety standards for industrial land, providing an efficient and economical one-stop solution for the remediation of complex contaminated plots.
Petroleum pollution resource utilization: thermal washing technology opens a new chapter in remediation
Desen Environment has innovatively launched a sludge contaminated soil thermal washing system for petroleum hydrocarbon pollution scenarios in oil fields and refining areas, and achieved precise temperature control and resource regeneration through graded heating and waste heat recovery technology. This technology can reduce energy consumption by 40%, waste heat utilization rate of 85%, waste oil recovery rate of more than 92%, and recycled oil products can be directly reused in the industrial fuel chain; after remediation, the total petroleum hydrocarbon (TPH) content in the soil is stably lower than 1000mg/kg, meeting the standards for industrial land. In the practice of Changqing Oilfield governance, the equipment has treated 120,000 cubic meters of oily soil, recovered 4,300 tons of crude oil, and generated revenue of more than 20 million yuan, successfully verifying the closed-loop model of "pollution control-resource recovery-economic value-added", and providing a new paradigm of high efficiency and low carbon for the restoration of oil-contaminated land.
Land is the carrier of civilization inheritance and the foundation of sustainable development. With the mission of "reducing pollution to zero and regenerating land", Desen Environment is providing solutions with both environmental and economic benefits for the "Battle for the Defense of Clean Land" through continuous technological innovation and scenario-based practice. Driven by policy and market demand, Desen Environment will continue to deepen its efforts in the field of soil remediation, build a strong ecological security barrier with the power of science and technology, and leave a solid mark in the journey of building a beautiful China.
