Organic contaminated soil management and control treatment system and application thereof

Abstract

The invention belongs to the technical field of organic contaminated soil in-situ management and control and safety guarantee, and particularly relates to an organic contaminated soil management and control disposal system and application thereof. Comprising a negative-pressure air guide layer, a power operation room and at least one group of negative-pressure air guide system, wherein the negative-pressure air guide layer is arranged at the bottom of a to-be-built building at the upper part of the site; the negative pressure air guide system comprises a negative pressure power system and a negative pressure air guide pipe network system; the negative pressure air guide pipe network system is laid in the negative pressure air guide layer; the negative pressure power system is arranged in the power operation chamber, connected with the negative pressure gas guide pipe network system and used for providing negative pressure power, and volatile and semi-volatile pollution gas entering the negative pressure gas guide layer is forcibly extracted and guided out through the negative pressure gas guide pipe network system. According to the invention, gaseous pollutants from lower-layer soil in sucked indoor air and gaseous pollutants from lower-layer soil in sucked outdoor air are eliminated, and human health risks in the proposed building are eliminated.

Description

technical field [0001] The invention belongs to the technical field of in-situ control and safety assurance of organic polluted soil, and in particular relates to a control and disposal system for organic polluted soil and its application. Background technique [0002] The vigorous development of the petrochemical industry has effectively promoted my country's economy and modernization. However, since the petrochemical industry involves the production and processing of various organic compounds, problems such as leakage and omission will inevitably occur during the operation process, especially in the early stages of industrial development. There are also erroneous disposal operations such as random dumping and accumulation of waste, which has caused soil pollution problems such as volatile, semi-volatile and petroleum hydrocarbons in the production site. With the continuous acceleration of the urbanization process in our country, the form of every inch of land in the city ha...

AI Technical Summary

Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to provide a control and disposal system for organic polluted soil and its application to solve the threat of secondary exposure of potential pollutants in the site after the control and disposal of the existing technology, so as to ensure the elimination of inhaled indoor air. Neutralize gaseous pollutants from subsoil and eliminate inhalation of gaseous pollutants from subsoil in outdoor air to ensure the elimination of human health risks in proposed buildings
