Research shows that corn can repair heavy metal contaminated soil

(Reporter Liu Rongfang’s correspondent Liu Huiyan’s photography report) The corn can be used to repair soil contaminated by heavy metals! Yesterday, the latest research jointly completed by South China University of Technology and other organizations won the first prize of the Guangdong Provincial Science and Technology Award. It is reported that the use of economic crop corn for heavy metal - organic compound remediation of soil technology technology has been carried out in a vegetable base in Baiyun District, Guangzhou City, heavy metal contaminated soil repair demonstration, repair effect is good.

Let contaminated soil "production-side repair"

Due to the pollution of waste water, waste gas and solid waste, and the application of chemical fertilizers, pesticides and sludge, heavy metals have accumulated in agricultural soil in the suburbs of the Pearl River Delta. The content of heavy metals in the soil is generally high, and soil pollution has become The bottleneck that restricts the healthy and sustainable development of modern agriculture.

The project “Study on the Environmental Chemical Behavior and Remediation Mechanism of Pollutants in Soil” completed by the South China University of Technology and other institutes focused on the release of heavy metals and pollutants from the release, migration and conversion of heavy metals and organic pollutants in the soil. The environmental chemical behavior of the removal process and the study of its repair mechanism, and the cultivation of soils contaminated by heavy metals and organic pollutants, can be used to develop a corn that uses the economic crop corn to perform "side-to-side repair" of heavy metals-organic matter contaminated soil. Repair technology.

According to reports, the results of this research have applied for 16 invention patents, and a remediation demonstration of heavy metal-contaminated soils has been carried out at a vegetable base in Baiyun District, Guangzhou City, with good results.

The Beijiang Levee can prevent floods in a hundred years

The Beijiang Levee is one of the seven major insurance levees around the country and is the most important embankment in Guangdong Province. The “Research and Application of Key Technologies for Upgrading Standards for the Beijiang Levee Reinforcement Project” completed by the Beijiang River Basin Authority of Guangdong Province has innovated the idea of ​​water management, and solved the pervasive seepage of the permeable foundation, the dangerous section of the dangerous sewers, and the vibration of the sluice. Water hidden project construction quality difficult to control and other major issues, and thus won the first prize of the Guangdong Provincial Science and Technology Award.

It is reported that after the construction of standards for reinforcement, the flood control standards for the Beijiang Levee have been increased from the original 50-year-one-flood flood to the 100-year-prevention flood, the Pearl River Delta more than 20 million, and the more than 100 million acres of arable land. Baiyun International Airport, Jingguang Railway, The important traffic lifelines such as the Wuhan-Guangzhou high-speed railway and the Beijing-Zhuhai Expressway have benefited from this.
