    -1-MOBILE MODULAR TREATMENT DEVICE FOR ORGANIC WASTE GAS IN
    SITE REMEDIATION Technical Field The present invention relates to waste gas treatment devices, and more specifically, to a mobile modular treatment device for organic waste gas in site remediation. Background With the acceleration of urbanization, large numbers of polluting enterprises have been moved out of the urban areas of city centers. Additionally, the relocation, shutdown or closure of industrial enterprises has left behind a large number of various kinds of complex polluted sites. Such sites typically experience substantial loss of value stemming from problems such as soil pollution, groundwater pollution, wall and equipment pollution, waste pollution and the like. A large number of polluted sites (also known as "brownfield sites") are the byproduct of industrial change and urban expansion. These polluted sites bring environmental and health risks, and hinder urban construction and local economic development. The solution is to remediate the sites. Remediation efforts are typically focused around industrial sites like petroleum, chemical, coking and so on, which are mainly caused by organic pollution. Pollutants are featured with organic solvents, such as compounds of benzene, halogenated hydrocarbons and petroleum hydrocarbons. The above-mentioned polluted sites will produce organic waste gas during the remediation process. The organic waste gas may contain not only organic pollutants in high concentrations (such as volatile organic compounds (VOCs)), but also smoke (powder), oil, acidic and malodorous substances (such as HS, SO, NOx), and have the characteristics of high temperature, high CO content, and complex composition. Summary The objective of the present invention is to provide a mobile modular treatment device for organic waste gas in site remediation, which can carry out waste gas treatment while in motion according to actual needs, which is convenient, fast and efficient. To achieve the above objective, the present invention provides the following technical
