The invention relates to a multiphase extraction well system which comprises an extraction well pipe, a backwashing device, an automatic cleaning device, a screen box and an outer screen. A screen pipe with screen seams is arranged at the lower end of the extraction well pipe, and a gas-phase extraction pipe and a liquid-phase extraction pipe are arranged in the extraction well pipe. The backwashing device comprises a backwashing pipe arranged in the extraction well pipe. The automatic cleaning device is arranged between the extraction well pipe and the screen box and comprises a pipeline brush moving up and down. A biofilm layer is attached to the surface of the screen box, and a filler layer fills the inside of the screen box. The layer of outer screen is arranged outside the screen box,a screen vibrator is installed on the outer screen, and the screen vibrator is controlled by a vibration controller to vibrate. The invention also relates to a multiphase extraction well system installation and cleaning treatment method. The method is easy to operate and high in adaptability. The screen can be cleaned in the extraction process, so that the extraction well pipe and the screen arecleaned smoothly.
Description
technical field [0001] The invention belongs to the technical field of in-situ multi-phase extraction and restoration of polluted sites, and relates to a multi-phase extraction well system for site soil pollution control and installation and cleaning disposal methods thereof. Background technique [0002] With the development of my country's economy and the continuous optimization and adjustment of industrial structure, a large number of polluting enterprises have been relocated or eliminated, leaving behind a large amount of polluted soil and groundwater, and there are serious environmental safety hazards, especially in petroleum, chemical and pesticide polluted sites, because of Pollutants are highly volatile, which can easily cause the spread of pollutants and threaten the health of the people. There is an urgent need for a green and sustainable restoration and treatment technology. In-situ remediation technology has been widely used in the treatment and restoration of con...
