An integrated and comprehensive soil in situ joint restoration equipment

Abstract

The invention discloses an integrated and comprehensive soil in-situ combined restoration equipment, which belongs to the technical field of soil restoration. The equipment mainly includes loading / unloading machine, heating oven, conveyor belt, vacuum pump, pulverizer, mixer, solid medicament dosing tank, Venturi delivery pump, ultrasonic atomizer, peristaltic pump, liquid medicament storage tank, Launderer, activated carbon adsorption purification tank, electromagnetic mud discharge valve and absorbent storage tank. The whole set of restoration equipment adopts a modular design, which can be flexibly matched and combined according to the different types of soil pollution to be repaired, so as to reduce costs. The whole set of equipment can also be installed on a trailer to realize mobile operation. The equipment of the present invention has various repair functions such as thermal desorption treatment, chemical oxidation / reduction, chemical leaching, etc., and can realize in situ joint repair of soil containing organic pollutants and heavy metal compound pollution, with high repair efficiency and wide range , No harmful gas emissions, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of soil remediation technology, specifically, it is a comprehensive soil in-situ joint repair equipment integrating heat treatment, chemical oxidation / reduction, and chemical leaching technology, which can realize the treatment of organic pollutants and heavy metal pollutants. heterotopic joint remediation of soil. Background technique [0002] Soil is one of the main resources that human beings rely on for survival. In my country, with the acceleration of industrialization, urbanization, and rural intensification in the past 20 years, the problem of soil pollution has become increasingly prominent, and the area of ​​soil polluted to varying degrees is constantly expanding. , posing a threat to the strategic goal of building a well-off society in an all-round way and realizing sustainable development. The main causes of soil pollution are the irrational development of mineral resources and their smelting discharge, lo...

Problems solved by technology

However, the complexity of site pollution, such as many types of pollutants, complex pollution, and complex and different soil structures, brings great challenges to site pollution remediation. A single remediation method is often limited by the characteristics of site pollution, so the development of a combination of multiple The integrated solution of restoration technology breaks through the limitations of a single restoration technology, and is an important development direction for future site restoration and related professional equipment
