General process of pollution remediation

Typical repair techniques

1.Stable curing technique

For Pb, Cr, Cd and other heavy metal contaminated sites with low thermal sensitivity, unstable toxic wastes are transformed based on physical and chemical methods Reduce the toxicity of wastes for stable solids

Features: heavy metal pollution remediation technology; High cost; The site is strong stars; Long-term monitoring is required after repair, and secondary development is limited; Short time limit for a project

2.Chemical oxidation technology

Adding chemical oxidants to the polluted environment depends on the oxidation capacity of chemical agents to decompose and destroy the structure of pollutants in the polluted environment, so that the pollutants can be degraded Or a repair technique that converts to a less toxic and less mobile substance

Features: remediation technology of organic pollution; High cost; Site adaptability; Safe and reliable after repair; Short time limit for a project

3.Thermal desorption technology

For Hg As and other volatile heavy metals and volatile organic pollutants (VOCs) contaminated sites, based on thermophysical and chemical methods, research and development of polluted Soil thermal desorption technology can reduce the content of pollutants and achieve the purpose of remediation by making pollutants volatilize or decompose directly or by heating

Features: a variety of pollution remediation technologies; The cost is high; Site adaptability; Safe and reliable after repair; Short time limit for a project

4.Gas phase extraction technology

Based on the physical method, the distribution ratio of pollution in the gas-liquid-solid phase was changed for the polluted site with better volatilization characteristics and permeability characteristics of soil layerFor example, the absorbed dissolved or free phase of pollutants into the gas phase, collection and treatment, thereby reducing the content of pollutants in the soil radio

5.Chemical leaching technology

For heavy metals (HMs), polycyclic aromatic hydrocarbons (PAHs), petroleum (TPHs) and other contaminated sites, based on chemical principles, through water or solubilization to strengthen drugsThe agent desorbs the pollutant from the soil phase, then carries on the mud water separation and the sewage treatment

Features: a variety of pollution remediation technologies; High cost; Site adaptability; Safe and reliable after repair; Short time limit for a project

6.Isolation blocking technique

Through all kinds of engineering technology means (isolation wall structure impermeable membrane structure, etc.), limit the migration of pollutants (surface migration and underground migration), cut off pollutionExposure pathways between the source and the receptor to achieve a contaminant barrier system that reduces the risk of contamination and protects the receptor

Features: various pollution remediation technologies; Low cost; Suitable for various sites: long-term testing is required after restoration, and secondary development is limited; Short time limit for a project

7.microorganism repair technology

It is suitable for remediation of soil contaminated by organic matter. Based on microbial method, pollutants can be absorbed and degraded as microbial nutrients

Characteristics: remediation technology of organic matter; Low cost; Simple operation; Safe and reliable after repair; The repair period is long; High environmental requirements


Based on the theory of plant tolerance and excessive accumulation of certain or certain chemical elements, plants and their co-existing microbial systems are used to remove pollution from the environmentpollution

Features: a variety of composite pollutant remediation technology; Low cost; Site adaptability; Safe and reliable after repair; A longer time
