Abstract

The invention discloses a soil leaching remediation reduction system and a construction method thereof, and belongs to the technical field of soil remediation. The soil leaching remediation reductionsystem comprises a feeding primary grading unit, a high-pressure jet separation unit, a secondary grading unit, a slurry settling concentration unit, a filter pressing unit, a sewage treatment unit, adust tail gas treatment unit and an instrument electrical control unit which are connected in sequence. According to the system, the grading quantity and the equipment quantity are greatly reduced, and for soil treatment of small-sized polluted sites, the whole system can adopt modularized container equipment or skid-mounted equipment which is convenient to move, so that the on-site constructioncost can be greatly reduced, the construction period can be greatly shortened, and the remediation efficiency is improved. The system is simple and ingenious in structure, easy and convenient to operate, low in equipment investment cost, small in occupied area, particularly suitable for remediation projects of small contaminated sites, capable of achieving multi-equipment parallel operation, suitable for treatment of medium and large sites, wide in application range, good in effect and wider in application prospect.

Description

technical field

[0001] The invention relates to the technical field of soil remediation, in particular to a soil rinsing repair reduction system and a construction method thereof. Background technique

[0002] Soil washing technology is an important restoration technology in soil restoration. Soil washing removes pollutants adsorbed on and within soil particles.

[0003] In the field of soil remediation, the soil particle size is usually classified, and the specific classification is as follows: boulder particle size > 256mm; medium gravel particle size: 64-256mm; fine gravel particle size: 2-64mm; sand: 1 / 16-2mm ; Silt particle size: 1 / 516 ~ 1 / 16mm; Clay particle size: less than 1 / 512mm.

[0004] Soil washing is an in situ and ex situ remediation technique that uses clean water (usually with some chemicals added) or solvents to remove pollutants from excavated soil. Clean water mainly plays two roles in the leaching process: 1. Separating coarse particles from fine pa...
