Taking an organic irrigation soil thermal desorption restoration project in Shanghai as an example,the process flow,construction plan and equipment composition of the construction reactor thermal desorption technology are introduced in detail,as well as the application of temperature,natural gas consumption,wastewater treatment and other applications during open-air thermal desorption operation.The results show that after natural gas is heated for 34 days,the temperature of the soil pile can reach above 150 ℃,which can realize efficient irrigation of chlorobenzene and aniline organic solutions in the soil.The amount of natural gas per 1 m3 of contaminated soil is about 30.6 m3,using"pollutant+adsorption"thermal desorption process treatment exhaust gas and"oxidation+coagulation"process treatment can achieve exhaust gas and wastewater reaching specimens.
