Soil remediation agent for treating heavy metal pollution and production method of soil remediation agent

Abstract

The invention belongs to the technical field of soil remediation, and in particular relates to a soil remediation agent for treating heavy metal pollution and a production method of the soil remediation agent. The soil remediation agent consists of the following raw materials in percentage by weight: 35 to 65 percent of active molasses yeast waste water chelate powder, 5 to 20 percent of silicon dioxide, 5 to 15 percent of calcium oxide, 1 to 10 percent of magnesium oxide, 0.3 to 10 percent of ammonium persulfate, 5 to 28 percent of humic acid and derivatives thereof, 0.1 to 15 percent of microcapsule inoculants, 0.1 to 5 percent of a macromolecular water-retaining agent, 0.1 to 5 percent of a heavy metal passivant, 1 to 5 percent of auxiliary agents and 1 to 45 percent of inorganic mixed fertilizer. Compared with the prior art, the soil remediation agent provided by the invention has the advantages that the organic waste liquid of yeast industry serves as one of the main raw material, so the environmental pollution caused by the organic waste liquid is reduced and the cost of the soil remediation agent is reduced; precipitation and biological action are combined, so a good effect of treating the heavy metal pollution is achieved; the main components also comprise organic fertilizer and inorganic fertilizer, so the heavy metal pollution can be effectively treated, production and income of crops are increased, continuous cropping resistance of the crops is achieved, and potential application and popularization values are achieved.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a soil remediation agent for controlling metal pollution and a production method thereof. Background technique [0002] According to the "National Soil Pollution Survey Bulletin" jointly issued by the Ministry of Environmental Protection and the Ministry of Land and Resources, the rate of heavy metals in the national soil exceeding the standard is 16.1%, and the proportions of slightly, lightly, moderately and heavily polluted sites are 11.2%, 2.3%, and 10%, respectively. 1.5% and 1.1%. From the perspective of pollution distribution, the soil pollution in the south is heavier than that in the north. The soil pollution problem in some areas such as the Yangtze River Delta, the Pearl River Delta, and the old industrial base in Northeast China is more prominent. At present, the poor quality rate of cultivated land in my country is 27.9%. Unlike the treatment o...
