Abstract
With the acceleration of urbanization and population growth, the volume of domestic wastewater discharge has been increasing continuously. Traditional wastewater treatment methods face challenges such as resource wastage and increased environmental pressure. To achieve sustainable development, this study focuses on resource recovery technologies in domestic wastewater treatment. Aiming to improve resource recovery efficiency, reduce treatment costs, and minimize environmental pollution, this research combines experimental studies with theoretical analysis. Typical domestic wastewater samples were selected and treated using physicochemical and biological methods to recover resources from the wastewater. The results indicate that by optimizing the combination of different treatment methods, pollutants in the wastewater can be effectively removed while achieving efficient recovery of nutrients such as nitrogen and phosphorus, as well as organic matter. Notably, an innovative composite material was proposed for the adsorption of heavy me tal ions in wastewater, significantly enhancing resource recovery rates while ensuring treatment effectiveness. This study not only provides new insights and technical support for domestic wastewater treatment but also plays a crucial role in promoting water resource recycling and alleviating resource shortages, contributing to the construction of a resource-conserving society.
