Abstract: With the rapid development of China’s industry, the large-scale combustion of coal carbon leads to a large amount of by-product fly ash accumulation and low utilization rate. At the same time, a large amount of nitrogen-containing wastewater is discharged into lakes, causing serious eutrophication problems. The synthesis of zeolite molecular sieve using fly ash as raw material can improve the problems of large accumulation of fly ash and eutrophication of water body to some extent. In this paper, two hot issues of resource utilization of fly ash and environmental pollution control are studied, and the characteristics and utilization status of fly ash are reviewed, as well as the classification, synthesis methods and influencing factors of zeolite molecular sieve. The application of zeolite molecular sieve in wastewater treatment and the characterization method of ammonia nitrogen adsorption effect were analyzed. The existing problems in this study were put forward and the future development trend was analyzed, in order to provide theoretical basis for the follow-up research.Abstract: With the rapid development of China’s industry, the large-scale combustion of coal carbon leads to a large amount of by-product fly ash accumulation and low utilization rate.

Abstract: This study aims to make full use of the PIE-Engine Studio remote sensing real-time computing cloud platform to comprehensively assess the ecological environment of the Yellow River Basin. In this platform, we constructed a monitoring system specifically for the Yellow River basin, which integrates multi-source remote sensing data to provide comprehensive ecological environmental monitoring and assessment. In the monitoring system of the Yellow River Basin, we have established modules such as river course change, water body monitoring, vegetation cover, and remote sensing ecological index analysis to comprehensively evaluate the trend of long-term evolution of the Yellow River Basin ecosystem. The channel change module tracks the changes in channel morphology through real-time remote sensing data, providing important information for water resources management. The water body monitoring module focuses on monitoring water quality and distribution to obtain a comprehensive understanding of the dynamics of water resources. The vegetation cover module uses remote sensing data to monitor vegetation cover and assess ecosystem health. The remote sensing ecological index analyzes heat, dryness, humidity, and greenness, and then evaluates the obtained results to obtain the final analysis and evaluation. By using the early warning point identification method, we comprehensively evaluated the ecological environment quality of the Yellow River across different spatial and temporal scales. This comprehensive assessment provides the local scientific basis, and provides strong support for the protection and planning decisions of the ecological environment, and provides detailed data and scientific basis for the ecological sustainable development of the Yellow River Basin.Abstract: This study aims to make full use of the PIE-Engine Studio remote sensing real-time computing cloud platform to comprehensively assess the ecological environment of the Yellow River Basin.

Abstract: The aviation industry is one of the top ten greenhouse gas emitters worldwide. Aviation fuel, as a non-renewable disposable energy source, is costly and emits a large amount of pollutants during the combustion process. Reducing fuel consumption during flights is an important research focus in the aviation industry. To achieve fuel efficiency and emission reduction in the aviation industry, one aspect is the accurate prediction of fuel consumption, estimating the required fuel for route flights to minimize unnecessary fuel consumption. Another aspect is to study the impact of various factors on fuel consumption based on the aircraft's performance and external environmental factors during different flight phases. This allows for the development of targeted strategies to reduce fuel consumption and emissions. This article aims to achieve fuel efficiency in aircraft by analyzing the current status of fuel consumption models, summarizing existing fuel consumption prediction methods, and identifying future trends in fuel consumption model development. It provides an overview of fuel consumption strategies for different flight phases and summarizes fuel-saving measures for each phase, offering academic support for fuel efficiency and carbon reduction in the aviation industry.Abstract: The aviation industry is one of the top ten greenhouse gas emitters worldwide.
