The study found that the overall content of some heavy metals in the soil exceeds the standard, and the impact on the environment cannot be ignored.
The proportions of heavy metals in the soil have different impacts on the surrounding environment and ecosystems. The related heavy metal elements contained in the soil refer to certain ions, molecules or other combinations of these elements. The physical and chemical form in which it exists. For example, mercury can have different chemical states such as elemental mercury, inorganic mercury, and organic mercury; iron can exist in divalent, trivalent, and elemental forms.
The form and specific distribution of heavy metals in the soil are affected by abiotic and biological processes, including: adsorption, sedimentation, and precipitation on the surface of minerals, through the dissolution and release of minerals, and the interaction with microorganisms and plants. effect.
Therefore, it can be seen that in the soil, the form of heavy metals determines the degree of harm, as well as the situation of migration and transformation.
The skid-mounted soil washing equipment developed by Desen Environmental has participated in many different types of soil remediation projects. For example, the 100 t/h Changsha Chromium Salt Plant chromium pollution overall treatment project, the Guangzhou Shipbuilding Heavy Metal Soil Pollution Remediation Project, the Hangzhou Iron and Steel Contaminated Soil Remediation Project, the Maanshan Iron and Steel Contaminated Soil Remediation Project, etc. The entire technological process is divided into seven modules, which have the functions of crushing and feeding, scrubbing, hydraulic screening, synergistic washing, cyclone dehydration, concentrated filtration and other functions, without changing the original use of the soil, and can well achieve the construction land standard.
The specific advantages are as follows:
(1) Wide range of applications: It can be used for cleaning and repairing various polluted sites such as chemical smelters, organic polluted sites, former sites of gas stations, and heavy metal polluted sites;
(2) Supporting capacity range: It can meet the requirements of multi-capacity projects, and realize the PLC intelligent control of the whole process from material feeding measurement, scrubbing classification, multi-stage cleaning, to mud filter pressing;
(3) The whole set of cleaning system is highly expandable: it can be flexibly deployed, increased or decreased according to the repair process of the project, and the overall system runs efficiently;
(4) The whole set of equipment has good series connection, high operating efficiency, and higher comprehensive project processing efficiency;
(5) Flexible transfer, fast installation, saving project costs, and avoiding the risk of secondary transfer pollution of contaminated soil.
(6) Water-saving and energy-saving benefits are obvious. The cleaning water can be recycled; variable frequency drive is used in many places, and the energy consumption is low.
The remediation of heavy metal-contaminated soil is very important. Only by ensuring that the soil can be restored can the level of ecological environment protection and people's quality of life be improved to the greatest extent. Skid-mounted soil washing equipment is a well-deserved first choice.
