Guangxi farmland restoration project
2019-04-18
Project introduction :
Located in Guangxi, the Lancang River is a first-class tributary of the Hongshui River. It originates from Houba Mountain in the southeast of Danxian County, southwest of Guangxi Province. It flows from the northwest to the southeast through the counties and cities of Nandan, Hechi and Du'an, and is located in Baiwang Township, Du'an County. Injected into the Red River. The source zone of the Lancang River Basin is a large-scale tin-polymetallic ore field in China's famous Dachang orefield. Over the years, unreasonable mine development has led to serious heavy metal pollution along the banks of the Lancang River. The area of contaminated cultivated land along the bank of the Lancang River is 386 hm2, of which the total abandoned area is more than 20 hm2.
The farmland along the Lancang River is mainly contaminated by heavy metals such as As, Pd, Cd and Zn, especially As arsenic is the most serious. Heavy metal pollution in the soil has led to a large number of crops that have been reduced or even rejected, resulting in pollution of the surrounding atmosphere and water environment. It is highly likely that the enrichment of food chains will endanger human health and cause chronic diseases and cancer.
Our company has achieved food safety standards for the repair and restoration of about 70 acres of heavy metal contaminated farmland in a certain area of the Lancang River Basin. The soil environment has been improved and the yield has increased significantly.
Repair target:
Using humic acid as a curing agent for in-situ solidification/stabilization technology, the contaminated soil is stabilized, the migration of pollutants is reduced, the potential health risks to the human body are eliminated, and the acceptance criteria are met, which guarantees the The site is safe to use.
