Embodiment 1

[0022] This embodiment provides a remediation reagent for soil or water organic pollution. The raw material components of the remediation reagent are calculated by weight percentage, including: dihydroxyguaiaretic acid (surfactant) 3%, monovalent potassium phosphate 2%, sea salt 2%, the balance is water.

[0023] The preparation method includes the following steps: after mixing dihydroxyguaiaretic acid (surfactant) and water, adding potassium monovalent phosphate and sea salt, then heating and boiling until a powder is formed; the mass ratio of powder to water is 3:100 Mix well to get repair reagent.

Embodiment 2

Abstract

The invention relates to a restoration reagent for organic pollutants in soil or water, and a preparation method and application method thereof. The restoration reagent comprises the following raw material components in percentage by weight: 2-4% of surfactant, 2-4% of phosphate, 2-4% of sea salt and the balance of water. The restoration reagent provided by the invention is a novel surface activity restoration agent, which has the enhancement characteristic and uses a surfactant as a base solvent. The restoration reagent has the function of dissolving and extracting organic pollutants in soil and water, and can perform a severe oxidative decomposition reaction with carbon chains of the organic pollutants; the phosphate and sea salt catalyze the chemical reaction; and on the premise of achieving the goal of in-situ restoration, the restoration reagent provides various nutrient elements to the soil and water, and thus, is especially suitable for restoring soil, water and other environmental media contaminated by organic pollutants. The restoration reagent is convenient to prepare and simple to use, and is safe and reliable.

Description

Technical field [0001] The invention relates to the technical field of environmental remediation, in particular to a remediation reagent for soil or water organic pollution, and a preparation method and use method thereof. Background technique [0002] Soil pollution has become a worldwide problem, and the pollution of organic compounds is the main type of soil pollution. According to preliminary statistics, there are at least 13-16 million hectares of arable land for pesticides and other organic pollutants in my country, which is increasing. Soil pollution can affect the decline of crop yield and quality, and can endanger human health through the food chain, and can also lead to further deterioration of the atmosphere and water environment. Therefore, the treatment of soil pollution has become urgent. [0003] Surfactant organic solvent substances can extract organic pollutants in the soil and further undergo oxidative decomposition, while inorganic salt substances catalyze the ...
