Abstract
With the acceleration of urbanization, water pollution has become increasingly severe, posing a significant threat to both ecological environments and human health. Traditional remediation technologies face challenges such as high costs and low efficiency. In this context, exploring the application of green technologies in urban water pollution control holds substantial significance. This study aims to uncover the potential of green technologies in addressing urban water pollution, offering new perspectives for pollution mitigation. By employing literature review methods, this research examines relevant theories and practical cases of green technologies both domestically and internationally. Additionally, field surveys provide an in-depth understanding of the current status of urban water pollution and the limitations of existing treatment technologies. The findings indicate that green technologies encompass various approaches: bioremediation utilizes microorganisms to degrade pollutants; eco-floating island technology constructs aquatic ecosystems to purify water quality; and constructed wetlands leverage plant root systems to adsorb and filter harmful substances. Compared to conventional methods, these green technologies offer advantages such as environmental friendliness, strong sustainability, and cost-effectiveness. Innovatively combining multiple green technologies into an integrated remediation model allows for flexible adjustments based on different pollution sources and levels, achieving more efficient and precise management of urban water pollution. This approach not only provides a new direction for urban water pollution control but also promotes a shift from end-of-pipe treatment to a combination of source control and ecological restoration, playing an indispensable role in improving urban water quality.
