Production of domestic soil remediation and washing equipment

China's heavy metal pollution is shifting from atmospheric and water pollution to soil pollution, and soil heavy metal pollution has entered a "concentrated and frequent period", posing a serious threat to the health of residents and the safety of agricultural products. This contaminated site was left behind after the relocation of the chemical plant. According to the preliminary investigation results, there is severe heavy metal pollution, including mercury, in the soil of the site（Hg）Cadmium（Cd）Significant enrichment, with mercury being the main pollutant with high concentration and large exceedance multiples, affecting shallow soil layers0-4 meters) causing serious pollutionThe level of risk to human health is unacceptable, and soil remediation and management work needs to be carried out.

Based on the nature and types of soil pollution on site, and feasibility analysis, it has been unanimously agreed to use ex situ soil leaching technology for remediation. butThe key technical parameters that affect the effectiveness of soil ex situ leaching and remediation mainly include:Soil fine particle content, nature and concentration of pollutants, water soil ratio, washing time, washing frequency, selection of synergists, treatment of high-efficiency washing wastewater, and reuse of chemicals. The concentration of heavy metal pollution in this site is very high, and the difficulty of remediation is beyond imagination. Therefore, we have decided to use our independently developed methodSkid mounted heavy metal soilRepair washing equipmentCarry out repairsReply. thisSkid mounted heavy metal soil remediation and leaching equipmentIt is developed by the in-depth research institute of soil ex situ leaching technology, and has the effect of "taking the essence and removing the dross". It can crush and sieve the soil into smaller parts0.25-0.075mmThe fine sand particles and the resulting wastewater can be recycled and reused, which meets the requirementsGB 8978Emission standards. The modular design of the pry assembly meets the needs of different processes and quick installation and transition. equipped5GIntelligent cloud management platform, which can be used inPCFlexible switching of multiple interfaces for remote operation on both mobile and mobile devices, and conducting comprehensive data analysis. The soil remediation of the site was successfully carried out as expected with the use of a lever mounted soil washing equipment100t/hThe amount of soil remediation has received strong recognition and high appreciation from customers.
