Abstract: Under the situation of the increasing shortage of global resources and the deterioration of the environment, circular economy, as a potential countermeasure, has gradually emerged as a key path to ensure the sustainable evolution of social economy. This study chooses the field of architecture as the starting point to analyze the application and improvement of spatial planning strategy from the perspective of circulation, hoping to realize the efficient closed loop utilization of resources. At the beginning of this paper, we summarized the essential characteristics of circular economy and its embodiment in the construction industry, and further studied the exemplary practice of circular economy in the European construction field, including policy support, demonstration projects and major obstacles faced. Then through the empirical investigation of the current situation of circular economy in China's construction industry, and compared with the examples in Eurasia, we explain the differences between China and the United States in this field and the causes. On the basis of these analyses, we construct a theoretical framework of spatial planning based on the concept of circular economy, design targeted tactics for different architectural schemes, and study the dynamic mechanism to ensure that the strategy takes root. Empirical evidence shows that accurate and adaptable spatial planning is tantamount to a significant improvement in the resource utilization of the construction industry, and also provides a strong support for regional and even national sustainable vision. Finally, we look forward to the future research blueprint, emphasizing the strengthening of international cooperation and dialogue to jointly meet the global difficulties, in order to accelerate the ecological and low-carbon transformation of the construction industry.

Abstract: This paper utilized field monitoring, model simulation, and theoretical analysis methods to study the agricultural non-point source pollution monitoring and load quantification under the construction of high-standard farmland, focusing on the demonstration project (Fengxiang area) implemented by the group. The calculated nitrogen and phosphorus loss coefficients for the high-standard farmland in the Fengxiang area were lower. The construction of high-standard farmland effectively controlled the loss of nutrients such as nitrogen and phosphorus. The agricultural non-point source pollution load for the Fengxiang area during a normal water year was determined to be 422.688 t (TN) and 447.576 t (TP). The research results can significantly reduce the cost of water pollution control caused by agricultural non-point source pollution, enhance the utilization of land resources, greatly mitigate the direct and indirect economic losses due to agricultural non-point source pollution, and provide valuable insights for sustainable agricultural development and ecological environment protection.

Abstract: With the rapid development of the chemical industry, a large amount of industrial wastewater is also produced, which contains a large amount of organic matter with high chemical stability and difficult to be biodegraded, such as acids, alkalis, salts, organic solvents, toxic dyes and heavy metal ions, which is very detrimental to the protection of natural ecology and the maintenance of human health. As a two-dimensional material, graphene's sp2 hybridized carbon atomic structure can produce π-π interactions with organic dye pollutants containing benzene ring structures, thereby adsorbing pollutants. Assembling two-dimensional graphene into a hydrogel with a three-dimensional network structure can further increase the contact area with pollutants and improve the adsorption of pollutants. This paper mainly discusses the research progress of the application of nitrogen-doped three-dimensional graphene hydrogels (NGHs) in water environment pollution remediation. Read More

Abstract: This paper reviews recent progress in research on graphene-based composite aerogels for wastewater treatment, with a focus on their preparation methods, structural characteristics, and performance in various wastewater treatment applications. Studies indicate that graphene-based composite aerogels possess excellent adsorption capacity, catalytic activity, and good regenerability, demonstrating significant potential in wastewater treatment. However, challenges such as the cost of graphene-based materials and structural stability in practical applications remain. This paper analyzes these issues and explores the future prospects for the application of graphene-based composite aerogels in environmental engineering. Read More

Abstract: With the acceleration of the global industrialization process, heavy metal pollution has become increasingly serious. Heavy metal elements pose a grave threat to the ecological environment and human health owing to their high virulence, strong persistence, and bioaccumulation. Therefore, developing efficient and environmentally friendly water treatment technologies to remove heavy metal (HM) in water has emerged as current focus of environmental science research. Graphene has shown significant application potential in water treatment owing to its unique physical and chemical properties. In particular, graphene composites can be further improved in water treatment by combining graphene with other materials. This paper systematically combs and analyzes relevant literature in recent years and summarizes the research progress of graphene composites (GCs) in removing HMs such as lead, mercury, cadmium, chromium and arsenic from water. The application status, mechanism of action, and performance evaluation of GCs in removing HMs in water treatment are discussed in detail. Finally, the challenges and future development directions are analyzed. Valuable reference and guidance for the further development of GCs in the field of water treatment are provided. Read More
