The invention discloses an ex-situ efficient skid-mounted leaching system for refined deep remediation of contaminated soil, and relates to the technical field of contaminated soil deep remediation equipment. The system comprises a roller mud making machine, a high-pressure spraying unit, a screening unit, an air floatation unit, a concentration tank, a water treatment unit, a belt filter press and a continuous soil bioremediation reactor, wherein the roller mud making machine is communicated to the screening unit, the high-pressure spraying unit is arranged in the screening unit, the screening unit is communicated to the air flotation unit, the air floatation unit is communicated to the concentration tank, the concentration tank is communicated to the water treatment unit, sludge concentrated in the concentration tank enters the belt filter press, the water outlet of the belt filter press is communicated to the water treatment unit, and the continuous soil bioremediation reactor is arranged at the side end of the belt filter press. According to the system, all water is treated by the sewage treatment unit and then recycled, so that secondary pollution is avoided while the operation cost is saved.
Description
technical field [0001] The invention relates to the technical field of deep restoration equipment for polluted soil, in particular to an off-site high-efficiency skid-mounted leaching system for refined deep restoration of polluted soil. Background technique [0002] The ectopic soil leaching remediation technology uses the eluent to combine with the pollutants in the soil, and achieves the goal of treating polluted soil through chemical or biological actions such as desorption, chelation, degradation, oxidation / reduction, dissolution or fixation of the eluent. Purpose. Ectopic soil leaching is a reduction process in which coarse particles are sieved and washed, and fine particles are enriched. Therefore, the refinement of sieving and grading and the full elution of pollutants are very important. Soil leaching technology is widely used, and the relevant technologies on the market are roughly the same at present, but the treatment scale is small, the process route is relativ...
