Problems solved by technology
[0006] Aiming at the deficiencies of the prior art, the present invention provides a device for quickly treating heavy metal ions in soil with auxiliary chelating agent and cooperative power supply, which solves the problem that the existing soil treatment device has a single structure, and the processing efficiency of heavy metal ions is relatively poor, and the price is expensive, and the processing It takes a long time. When the existing devices deal with heavy metal ions, the treatment method is single. It is difficult to separate heavy metal ions from the soil, and the heavy metal ions are unstable and inconvenient to precipitate. As a result, after the treatment of the soil, the content of heavy metal ions in the soil remains bigger problem

The invention discloses a device for rapidly treating heavy metal ions in soil with auxiliary chelating agent and synergistic power supply. A motor is fixedly connected to the top of the purifier, a transmission shaft is fixedly connected to the output end of the motor, a dispersing rake is fixedly connected to the bottom end of the transmission shaft, and a first hydraulic pressure is fixedly connected to both sides of the inner top of the purification tank close to the motor. The invention relates to the technical field of soil heavy metal ion treatment. The auxiliary chelating agent and the device for fast treatment of heavy metal ions in soil with power supply are equipped with various soil treatment methods to work together. Through two sets of electrodes, the soil liquid can be electrically treated, and the heavy metal ions in the soil liquid can be adsorbed. At the same time, by adding The chelating agent can increase the stability of heavy metal ions and facilitate the separation of heavy metal ions and soil.
Description
technical field [0001] The invention relates to the technical field of soil heavy metal ion treatment, in particular to a device for fast treatment of soil heavy metal ions with auxiliary chelating agent and synergistic power supply. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium, and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanide, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge and manure. If it exceeds the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, inhibit the activity of microorganisms, and gradually accumulate harmful substances or their decomposit...
