Technical service for contaminated soil microbial remediation

Technical Principle:

The technique utilizing four types of microbial soil remediation materials, including bio-crude oil-degrading microbial agents, the technology integrates crude oil-degrading microbial agents with immobilized microbial treatment techniques to reduce oil contents in oil and ensure effective remediation.

Microbial Remediation Process:
Microbial agent cultivation → Soil pretreatment → Microbial agent application → Mixing and turning → Backfilling and ecological restoration.

Microbial Assisted Phytoremediation Combined Process:
Microbial agent cultivation + Plant selection → Soil pretreatment →Microbial agent application → Mixing and turning → Backfilling → Plant cultivation → Field management.

Technical Parameters:

Soil contamination concentration: Oil content < 5%

Soil particle size: < 40 mm

pH value: Neutral, preferably 7–8

Temperature: 15–40°C

Moisture content: 20–30%

Oxygen content: 2–4%

Post-Remediation Effect:
Soil oil content < 0.45%

Technical Advantages:
Simple operation; low cost; high effectiveness; no risk of secondary pollution; environmentally friendly.
