AI Technical Summary
Existing technologies for the remediation of VOC-polluted groundwater are characterized by low efficiency, high energy consumption, and a tendency to generate secondary pollution. Traditional remediation devices rely on conventional power supplies, leading to carbon emissions, and the treatment process can easily cause secondary air pollution.
An ozone treatment device is used in conjunction with photovoltaic panel power supply. The groundwater is atomized into micron-sized particles through the air-lift device layer pipe and nozzles. These particles react with ozone to remove VOCs. The exhaust gas collection device recovers residual ozone, realizing groundwater recycling treatment, reducing extraction operations, and expanding the remediation scope.
It improves VOC removal efficiency, reduces energy consumption and carbon emissions, reduces the risk of secondary pollution, saves on the construction and operation and maintenance costs of remediation wells, and achieves green remediation.
