Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment: see figure 1 ,

[0033] A complete set of equipment for ectopic leaching and repairing of soil, including a wet screening mechanism, a spiral grading mechanism, a leaching and repairing mechanism, a wastewater treatment mechanism, and a wastewater recycling mechanism arranged in sequence. The cleaning and repairing mechanism separates coarse gravel, fine gravel and clean soil to form soil ectopic leaching and repairing process. The wastewater output from the spiral classification and leaching and repairing mechanism is separated into sludge and treated water by the wastewater treatment mechanism, and the treated water passes through the wastewater The recycling mechanism is sent to the wet screening mechanism or / and the spiral classification and rinsing repair mechanism to form waste water recycling.

[0034] The polluted soil to be treated is trans...

Abstract

The invention provides soil ectopic leaching restoring complete equipment, belongs to the technical field of site contamination repairing, and solves the problems that existing leaching equipment is generally poor in soil texture applicability, single in repairable pollutant, numerous and jumbled in leaching equipment system, high in operation intensity, large in water consumption and drainage quantity and the like. The equipment comprises a wet-type screening mechanism, a spiral classifying mechanism, a leaching restoring mechanism, a waste water treatment mechanism and a waste water recycling mechanism which are arranged successively, and polluted soil is separated from the spiral classifying mechanism and the leaching restoring mechanism via the wet-type screening mechanism to obtain coarse gravels, fine gravels and clean soil so as to implement a soil ectopic leaching restoring process. The soil ectopic leaching restoring complete equipment is suitable for restoring of heavy metal and / or organic polluted soil and ectopic leaching restoring of soil with different grain diameters, and has the advantages of wide application range, good decrement effect, stable repairing effect, simplicity and convenience in operation and running, small water consumption, high waste water recycling rate and the like.

Description

technical field [0001] The invention belongs to the technical field of site pollution remediation, in particular to a complete set of equipment for ectopic leaching and remediation of soil. Background technique [0002] Soil is the basic environmental element that constitutes the natural ecosystem, and it is also the material basis for the survival and development of human beings. With the intensification of the impact of human activities on the natural environment, pollutants generated in the production and life of people may enter the soil through various channels and exceed the capacity of the soil to accommodate and purify, resulting in soil natural dysfunction and deterioration of soil quality. In turn, it may have serious adverse effects on nearby humans and the surrounding environment. Therefore, it is necessary to adopt reasonable technical means to remediate contaminated soil, so as to effectively control the human health and ecological environment risks caused by ...
