Problems solved by technology

[0010] These methods have their own advantages and disadvantages, and most of them are used for water pollution control, but not many are used for large-scale soil pollution control, because the cost is too high, there is secondary pollution, and at the same time, it is not clear enough

Abstract

The invention provides a technology for removing residual antibiotics / pesticides in oil in situ and remediating soil and application, and belongs to the field of environmental protection. The technology comprises the following steps: adding FeCl2 to the soil polluted by antibiotics and organic pesticides; irradiating with ultraviolet rays; then adding proper amount of hydrogen peroxide / ozone water; and stirring to completely oxidize and decompose all antibiotics and / or organic pesticides. With the adoption of the technology, all antibiotics and / or organic pesticides are completely oxidized and decomposed, so that secondary pollution is avoided, and the pollution and harm of antibiotics and pesticides to the soil can be removed; the environment and the ecological system can be protected; and the human sustainable development is kept.

Description

technical field [0001] The invention belongs to the field of environmental protection, and particularly relates to an in-situ elimination and restoration technology and application of soil residual antibiotics and pesticides. Background technique [0002] Soil pollution, especially chemical plants, oil refineries, petrochemicals, gas stations, organic waste landfills and other places, organic pollution caused by various petroleum products, organic chemical monomers, intermediate products and end products, as well as papermaking Organic pollution caused by factories, food factories, fine chemical factories, liquefied gas factories, dye factories, pesticide factories, etc. is becoming more and more serious in our country. The main organic pollutants in the soil are pesticides, chloral, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, petroleum, methane, etc., among which pesticides are the most important organic pollutants. [0003] Organic pollutants in soil main...
