Description

Technical Field

[0001] The present invention belongs to the technical field of alkaline groundwater treatment, and in particular relates to an alkaline groundwater treatment device and a use method thereof. Background Art

[0002] Groundwater is one of the world's most important water resources, providing a critical source for daily life, agricultural irrigation, and industrial production. However, with the rapid development of urbanization and industrialization, pollution from volatile organic compounds (VOCs) has become a growing concern. VOCs primarily originate from wastewater and exhaust emissions from industries such as chemical, oil extraction, smelting, printing, and pharmaceuticals. Once these compounds enter groundwater, they pose significant risks to the ecological environment and human health due to their high volatility, resistance to degradation, and toxicity.

[0003] VOC-contaminated groundwater usually has a high pH value and exhibits strong alkaline characteristics. The treatment of this type of groundwater is difficult, mainly due to the following reasons: (1) VOCs are difficult to dissolve in water, and traditional water treatment methods have low removal efficiency; (2) the strong alkaline environment may affect the applicability of some purification technologies. For example, the biodegradation method is limited in microbial activity under high pH conditions, resulting in reduced degradation efficiency; (3) VOCs often coexist with other pollutants in groundwater (such as heavy metals, ammonia nitrogen, etc.), which increases the complexity of treatment. Most existing technologies first extract groundwater and then introduce the extracted groundwater into a sedimentation device for sedimentation treatment. However, this treatment method is too inefficient and the groundwater treatment quality is not high. Summary of the Invention
