At present, the problem of soil pollution is getting more and more attenti.
In this context, on the morning of June 16, 2022, the online seminar on heavy metal contaminated soil treatment hosted by ACI Environmental Protection, Thermo Fisher Scientific, and Environmental Protection Online was launched on ti.
The seminar invited outstanding experts in the industry to set up sample sit.

Heavy metal pollution site treatment technology and engineering cases from the world's top 500 companies China Minmetals and China Metallurgical backbone subsidiary - China ENFI Engineering Technology .
, L.
Hao Jianqing, director of the Soil Remediation Office of the Ecological Environment Division, carried out the heavy metal pollution site treatment technology and engineering case shari.
Director Hao introduced the commonly used heavy metal remediation technologies and the treatment strategies of heavy metal contaminated plots, which can be removed from the soil and changed its fo.
Then he introduced the solidification/stabilization technology, soil leaching technology, electric remediation technology, and biotechnology in deta.
7 common technologies including restoration, cement kiln co-processing technology and risk management and control technolo.
Regarding the actual case, Director Hao shared the contaminated soil remediation project at the original site of the heavy steel iron-making plant and the soil pollution of the Nanning Jiangnan Center project in Guang.
At the same time, considering factors such as project implementation conditions and social conditions, two restoration modes of in-situ ex-situ restoration, ex-situ treatment or disposal are select.
After determining the technical route, Director Hao introduced the main contents of the 16 projects in detail in the design of the project pl.
The soil pollution of the Jiangnan Center Project in Nanning, Guangxi, and ENFI is responsible for the construction drawing desi.
According to Director Hao, in the design, the main focus is on environmental protection (soil remediation), with multi-professional cooperation; the treatment process is the main functional unit, and multiple units are connected and matched; the temporary construction is mainly used, and various forms of construction assistan.
Then one by one, the various professional fields and applications that need to be involved in the construction design are introduc.
How is direct push technology applied in the investigation and restoration of heavy metal contaminated sites? Wang Qingwei, deputy general manager of Nanjing Yirun Environmental Technology .
, L.
, introduced the application of direct push technology in the investigation and restoration of heavy metal contaminated sit.
According to .
Wang, the direct-push technology refers to the direct-push drilling rig that penetrates the drill pipe with the built-in sampler and sensor into the formation by means of propulsion, shock or vibration, so as to quickly collect representative soil, soil gas and groundwater sampl.
Or the general term for the technology that obtains relevant data through the equipped testing instrumen.
.
Wang introduced Nanjing Yirun's EP1000 series of portable, crawler-type direct push drilling rigs, EP2000 series crawler-type direct push drilling rigs, EP4000C crawler-type direct push drilling rigs and EP3080 workstations, and their applications in soil survey and sampli.
Regarding the application of direct-push technology in soil remediation, .
Wang believes that the application of direct-push technology in the remediation of heavy metal contaminated sites belongs to in-situ remediati.
Different direct-push drilling equipment can be used to remediate heavy metal-contaminated soil by in-situ injection of microorganisms, activated carbon, e.
function with groundwat.
Case Analysis and Thinking of Heavy Metal Pollution Remediation Zhou Hong, director of the Technology Department of the Restoration Division of Yongqing Environmental Protection .
, L.
, shared the case analysis and thinking of heavy metal pollution remediati.
After a brief introduction to the heavy metal restoration technology, Minister Zhou analyzed the case of an electroplating plant in Jiangsu, a project in Hebei, e.
, as well as their treatment proce.
The Hebei project adopted mildly polluted soil (resource utilization) + moderately polluted soil (in Ex-situ solidification stabilization + in-situ ex-situ chemical oxidation + barrier landfill) + arsenic heavily polluted soil (qualified unit treatment) sche.
Minister Zhou believes that heavy metal pollutants have strong heterogeneity on a small scale (especially topsoi.
During the investigation process, the error generated by the sampling point is far greater than the total error generated by the sample preparation and analysis, and the field tone specification requires For 20*20 or even 10*10-units, one discrete point per unit is routinely used, which will lead to a big difference between the survey results and the subsequent repair wor.
In addition, the current new normative trend has put forward new requirements for the investigation process, and the third-party supervision is separated from the collection and measurement, so the representativeness of the data will become a difficult point to be solved in the investigation proce.
In areas with high economic benefits, the corresponding processing back-ends are fully matched, and the corresponding policies are highly matched, which can quickly form the downstream end of heavy metal processing; but for areas with low economic benefits, the back-end is missing, and there are very few corresponding receiving en.
How to deal with it? To achieve the goal of reducing the total amount? Minister Zhou suggested that from the risk assessment stage, multi-party demonstration of risk management and control strategi.
