Abstract

The invention belongs to the technical field of soil remediation, and specifically relates to a method for periodic compound repair of arsenic-contaminated soil, which mainly includes the following steps: transplanting centipede grass to form and prepare a repair layer, and at the same time, electrochemically repair the soil, and harvest after a period of repair Centipede Grass is tested, and according to the test results, it is judged that the repair is completed or the electrochemical repair is performed again or the natural repair is carried out. In the method of the present invention, each step is closely connected, and the cycle mode is judged according to the detection value, so as to avoid unnecessary waste of time and cost; the repair device and equipment are compactly arranged, and the pH of the soil and the electrode chamber is adjusted in real time, and the acid and alkali are adjusted by the automatic control device The ratio of the liquid storage tank is high in stability and flexibility. The cycle mode can be changed according to the test results, and the arsenic is completely repaired, and the final repair can reach more than 98%.

Description

Technical field [0001] The present invention is a soil repair technology field, which involves a periodic compound repair method of a arsenic pollution soil. Background technique [0002] my country is one of the countries with severe arsenic pollution. In addition to chemical and agricultural production, arsenic pollution is also a large amount of arsenic from the Japanese invasion of China after World War II.Arsenic is a carcinogenic and teratogenic element. Pollution water and soil can cause huge threats to human and ecological environment. Therefore, my country has carried out various types of arsenic removal research earlier. [0003] The restoration technology of commonly used arsenic pollution soil mainly includes the following: [0004] 1. Stability and solidification method: First analyze the pollution level of pollution substances, and then match the targeted treatment of pharmaceuticals, mix the soil contaminated with arsenic with 10 ~ 30%, add mixed water in the mixer...
