Soil restoration looks forward to "Green Sustainable Technology"

Green Sustainable Rehabilitation philosophy requires the concept of uphold the green, from the perspective of environmental protection and human health, choose the best repair techniques and programs. As to what kind of technology is green repair technology, the consensus of the industry is that the impact on the environment can be minimized, and the design and implementation of energy saving and carbon reduction and expanded recovery implant repair technologies such as phytoremediation, bioremediation, soil remediation Re-use or physical and chemical biological joint repair techniques. Since the "Soil Pollution Prevention and Control Action Plan" (Article 10) was released in the past year, the state is accelerating the formulation of laws, regulations and standards. "Well, after the NPC deliberations, the newly revised" Soil Pollution Prevention Law "may be faster than we expected a little time to come out." In the recently held China Sustainable Rehabilitation Conference, Ministry of Environmental Protection Nanjing Environmental Science Research Researcher Lin Yu lock said. Soil remediation policies frequently introduced, the market demand, but also led to the development of related industries. It is predicted that the soil remediation industry will become one of the largest segments of environmental protection in the "13th Five-Year Plan" period with a market potential of up to 4.6 trillion yuan. Due to the long-term environmental management, the soil remediation industry is expected to continue its long-term growth. To this end, many related businesses want to take the opportunity to make a big deal in the field of soil remediation. According to the actual situation of soil remediation in our country, mastering advanced soil remediation technology and site investigation and testing technology has become an entrance for enterprises to enter the field of soil remediation. Full green life-cycle sustainable restoration Remediation technology is a common focus in the repair industry, but a comprehensive, systematic and realistic remediation program is even more important. Our time to get involved in soil remediation is still very short. The concept of "green sustainable restoration" is also introduced from abroad. The so-called green sustainable restoration, the United States Environmental Protection Agency (EPA) gives the definition is: a remediation behavior that takes into account all the environmental effects of rehabilitative behavior can maximize environmental benefits. "In many contaminated plots need to be repaired, the limited resources available, so from top-level design to project implementation must optimize the allocation of resources, the most effective use of money, the most need to divert risk removed." Tsinghua University Houde Yi, an associate professor at the University, said of the core of green sustainable restoration. Houde Yi emphasized that the decision-making process based on the whole life cycle is extremely important for green sustainable restoration. "In the field of remediation, the traditional decision-making process is mainly focused on repairing the site itself and trying to reduce the concentration of pollutants." The new sustainable remediation is more and more considered the impact of repairing the site. For example, the use of repair reagents in the production process Caused by the environmental impact of landfill will be contaminated soil transported to the venue on the traffic, the long-term impact of landfill. He said that at present, there are still some problems in the field survey of many projects in our country, leading to over-repair problems in the repair programs. "Over-repairing often leads to a more extensive restoration because of the lack of precision in site surveys, and there are some areas that are contaminated but not found." In this regard, he suggested that the contaminated sites be accurately repaired, to avoid over-repair.
