Abstract

The invention provides a multi-stage type soil in-situ aeration system. The multi-stage type soil in-situ aeration system comprises an automatic control device and an aeration device. The automatic control device comprises a programmable logic controller (PLC), a transmitter, a frequency converter, a baroceptor, a lifting device and an aeration machine, wherein the PLC is connected with one end of the transmitter, one end of the lifting device and one end of frequency converter, the other end of the transmitter is connected with the baroceptor, the other end of the lifting device is connected with the aeration device, the other end of the frequency converter is connected with one end of the aeration machine, and the other end of the aeration machine is connected with a gas injection pipe of the aeration device. The aeration device comprises a first sealing device, a second sealing device, the gas injection pipe and an aeration pipe, wherein the upper end of the first sealing device is connected with the lifting device, the gas injection pipe is sleeved with the first sealing device, the upper end of the gas injection pipe is connected with one end of the aeration machine through a pipeline, the upper end of the aeration pipe is connected with the lower end of the gas injection pipe, and the lower end of the aeration pipe is connected with the second sealing device; both the first sealing device and the second sealing device are arranged in an aeration well, and a sealed space is formed through the first sealing device, the second sealing device and the wall of the aeration well; the baroceptor penetrates through the first sealing device through a connecting line and is arranged in the sealed space.

Description

technical field [0001] The invention relates to the field of soil pollution restoration, in particular to a multi-stage soil in-situ aeration system. Background technique [0002] Soil aeration technology (AirSparging, AS) is an in-situ remediation technology for dealing with volatile organic pollutants in soil. Due to its advantages of low cost, high efficiency and in-situ construction, it is widely used in soil with small molecular weight. , Remediation of volatile organic pollutants. AS technology injects compressed air into the soil, and during the upward movement of the gas, volatile organic pollutants enter the gas phase from the soil, and then the air containing pollutants is treated through the gas phase extraction system, so as to achieve the purpose of removing pollutants. In addition, the injected air accelerates the removal of pollutants through aerobic biodegradation. [0003] However, through laboratory research and site engineering applications, it is found ...
