Abstract
The invention discloses a soil restoration agent and a method for restoring organic contaminated soil or mercury contaminated soil. The soil restoration agent comprises a ferrous chloride solution with the pH being 4-5 and the mass concentration being 3-5%. The method for restoring organic contaminated soil or mercury contaminated soil comprises the following steps that to-be-restored organic contaminated soil or mercury contaminated soil is taken; the soil restoration agent is prepared; the soil restoration agent is added into the to-be-restored organic contaminated soil or mercury contaminated soil, mixing and stirring are conducted, and a mixture is obtained; and the mixture is arranged in a microwave reactor for reaction, and restored soil is obtained. The soil restoration agent and the restoration method which are provided by the invention and used for restoring organic contaminated soil or mercury contaminated soil efficiently restore soil and are high in desorption efficiency.
Description
technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation agent and a method for remediating organic-polluted or mercury-contaminated soil. Background technique [0002] Nearly three decades of economic growth, industrialization and urbanization have brought great material wealth to China and improved people's living standards. However, energy consumption and industrial and agricultural production activities have seriously damaged China's ecological environment. Air pollution, water pollution, soil and groundwater pollution are always threatening people's health and restricting the further sustainable development of China's economy. [0003] Mercury pollution is highly toxic, persistent, and easily accumulated by plants into the food chain, causing acute or chronic poisoning to humans, which has attracted widespread attention at home and abroad. In recent years, my country has strengthened the control of mer...
