METHOD AND SYSTEM USING MICRO/NANO BUBBLES FOR IN SITU REMEDIATION OF GROUNDWATER

摘要

A method using micro/nano bubbles for in situ remediation of groundwater. An injection well is arranged at an upstream location of an area where the groundwater (7) is polluted by an organic pollutant. A micro/nano aerator apparatus (1) is placed into the injection well. Electricity is supplied via a solar power supply apparatus (9) or a battery. Remote monitoring and control from the ground are implemented via a remote wireless communication device (6). Air (4) and water are passed through the micro/nano aerator apparatus (1) to produce micro/nano bubble water (8); same is introduced into a groundwater (7) system, and directly decomposes the organic pollutant or continuously replenishes electron acceptors for microorganisms. This facilitates the degradation and removal of the organic pollutant, while at the same time arranges a monitoring well to monitor and to analyze in real-time parameters during the removal process of the organic pollutant, and remotely adjusts the occurrence time of the micro/nano bubbles, the amount of water injected, and the amount of aeration. Also provided is a system implementing the method using the micro/nano bubbles for remediation of groundwater. The method and system are of reduced costs.
