Soil repair technology

  • Sludge treatment technology
  • Soil Thermal Repair Technology

Introduction to the process:
The waste water recovery system with the sound field strengthening as the main process was developed for the floor oil sludge, the bottom oil sludge and the odd color environment. Under the synergistic effect of the sound field, the oil in the sludge was removed efficiently, and the treated oil content could reach 1 % Below (industry standard <2%).

Technical characteristics:
Energy consumption, less investment, low cost
Winter can work
Public auxiliary requirements are low, no need for external gas
The process of no waste water, waste secondary pollution
Equipment automation, modular
Pharmacy green, no pollution

Technical principle:QCUW multidimensional sound field enhancement from multiple dimensions of the dimension, the rapid separation of oil and mud particles.
QCUW system integrates multi-dimensional sound field, decentralized mode adjustable, microscopic vibration violent, stubborn combination of oil and mud peeling interface more.
The rapidly separated oil droplets in the QCUW multidimensional sound field enhancement system are adsorbed to the surface by the microbubble interface generated by the system, and the sediment remains in the water level, thus ensuring complete separation and reducing the secondary re-aggregation process.

Typical process:

Introduction to the process:
Soil thermal repair technology is designed for soils that are contaminated with organic matter or low boiling point heavy metals, such as chemical-contaminated soils in the chemical plant, oily sludge in the petrochemical industry, and low-boiling heavy metal (mercury) contaminated soils. Through the heating of contaminated soil, so that pollution sources (organic matter, crude oil, low boiling point heavy metals, etc.) into a gaseous, and thus out of the soil, to achieve the separation of pollutants.

Technical characteristics:Pyrolysis desorption technology has a quick effect, the repair effect is complete and so on; Applicable to a wide range of petrochemical industry can be used for oil sludge, crude oil contaminated soil, oil-based drilling debris and other contaminated soil repair can also be used for chemical plant organic pollution Land restoration.

Process flow:

Introduction to the process:Taking the oil sludge treatment in the petrochemical industry as an example, the oil-contaminated soil is sieved through the pretreatment unit to reach a certain particle size and transported to the pyrolysis desorption unit through the feeding system. In the pyrolysis desorption unit, the contaminated soil is heated to 450 ℃ -650 ℃. The oil in the soil volatilizes and cleaves, leaves the soil into the gas phase and enters the capture unit with the carrier gas flow. The contaminants are captured and separated into the separation unit for separation of the oil and the collector. The separation of the collector recovery trap system continues to be used. Non-condensable gas is rich in low boiling point hydrocarbons, after purification treatment into the pyrolysis desorption unit of the combustion chamber, the incineration instead of part of the fuel. After the heat treatment of the soil after the dust and dust after the qualified soil.
