Problems solved by technology

However, there are obvious deficiencies in the natural attenuation monitoring technology. A considerable number of monitoring wells need to be built, and the continuous tracking and monitoring takes a long time. Long-term monitoring needs to bear high detection costs
In addition, the natural attenuation monitoring technology is still monitoring on "points", which is not accurate enough to describe the spatial distribution of underground pollution halos, and it is not accurate to grasp the trend of its migration and diffusion

[0074] Risk control of soil and groundwater pollution in a heavy metal-organic compound polluted site

[0075] The original use of the site was chemical plants, small factories, etc. The historical production situation is complicated, and the site covers an area of ​​7685.85m 2 , Carry out on-site survey and data collection within 500m of the site and surrounding environment. The site began to build factories and produce after 1990. Early chemical plants may have problems such as irregular production management and lax environmental protection supervision. During the production process, the site may be affected. Water and soil environment pollution. After the chemical plant stopped production in 2006, the original plant was transformed into a garment factory, a cement additive production plant, a plastic product processing plant, and a water pump assembly processing plant. At the beginning of 2017, the factory buildings on the site were demolished and the land leveling was co...

[0109]Risk control of soil and groundwater pollution in an organic polluted site

[0110] The chemical plant covers an area of ​​about 24 acres and was built around 1991. It mainly deals in coatings, chemical solvents, benzyl chloride, chemical additives, trimethoxyaldehyde benzaldehyde, reagents, industrial alcohol, and paoin water. At the end of 2016, the site was demolished and reclaimed into agricultural land. Before the site survey was carried out, all the buildings and floors in the site were demolished, the construction waste had been completely removed, and the land had been leveled. The historical data of the factory area is unknown, and the original layout of the factory area cannot be determined during the on-site survey.

[0111] Invent a soil and groundwater risk management and control method that combines non-destructive scanning detection technology and monitoring natural attenuation, and complete the site pollution investigation and soil and groundwater pollut...

Abstract

The invention discloses a polluted site soil groundwater pollution risk management and control technical method. The method comprises the following steps: 1) carrying out site analysis and survey; 2) carrying out first-time full-field lossless scanning detection, identifying and delineating a pollution halo; 3) arranging soil and underground water monitoring points in a targeted manner; 4) carrying out full-field lossless scanning detection irregularly, 5) comparing lossless scanning detection results, 6) carrying out natural attenuation monitoring on soil and underground water pollutants, 7) adjusting the arrangement and sampling frequency of the soil and groundwater monitoring points according to the nondestructive scanning detection result; and 8) accurately tracking the pollution degree and drift range of the field pollution halo by combining the multiple full-field nondestructive scanning detection results and the soil and groundwater monitoring data. According to the invention, lossless scanning detection and natural attenuation monitoring are combined to be applied to tracking detection and early warning of the soil and underground water pollution halo of the polluted site, the precision is high, the cost is low, the interference is small, the omnibearing real-time pollution risk management and control of the site can be realized, and the coping efficiency and precision of diffusion and migration of the pollution halo are obviously improved.

Description

technical field [0001] The invention belongs to the field of environmental monitoring and engineering technology, and relates to a risk management and control method for soil and groundwater pollution in polluted sites that are not in a hurry to develop (idle) polluted sites that combine non-destructive environmental geophysical exploration and monitoring natural attenuation, and especially relate to a method that is aimed at not in a hurry to develop (idle) polluted sites. Develop (idle) contaminated site soil and groundwater pollution risk management and control technology methods that combine full-field non-destructive scanning detection and monitored natural attenuation. Background technique [0002] With the successive promulgation of the national "Soil Pollution Prevention and Control Action Plan", "Soil Pollution Prevention and Control Law", "Contaminated Land Soil Environment Management Measures", "Water Pollution Prevention and Control Action Plan", "Groundwater Poll...
