Energy Conservation and Environmental Protection

This study investigates the steel structure hoisting and installation challenges beneath a long-span elevated floor in a commercial complex project in Changning District Shanghai. Through comprehensive analysis, we optimized hoisting point layouts and material storage areas. The integrated implementation of tower cranes and mobile cranes, combined with the erection of temporary supports and phased load release protocols, enabled precise positioning of large-span steel structures. This methodology effectively resolved complications including restricted hoisting operations in complex elevated spaces, stringent installation accuracy requirements, and confined construction site conditions. Furthermore, the steel structure installation procedures and technical specifications were concluded. It can provide valuable references for analogous steel construction projects.

This article analyzes the energy-saving potential of equipment such as transformers, motors, and lighting from both technical and management perspectives. It proposes renovation plans such as reactive power compensation, variable frequency speed regulation, and intelligent monitoring, and explores ways to improve energy-saving benefits. Research can provide theoretical and practical references for the fields of industry and architecture.

This article is based on the practice of a certain landscaping engineering company in Beijing, focusing on the collaborative innovation of landscaping construction technology and landscape design. In response to the problems of extensive construction technology, homogeneous design, and insufficient ecological benefits in the current industry, a solution of "technology empowerment+design driven" is proposed. By analyzing key technological breakthroughs such as soil improvement, water-saving irrigation, and prefabricated construction, and combining innovative design concepts such as ecological priority, cultural narrative, and intelligent interaction, a "construction design operation and maintenance" full cycle collaborative mechanism is constructed. Taking the regional characteristics of Beijing as the starting point, strategies such as climate adaptive plant configuration and modern translation of royal garden elements are proposed, and technology implementation is achieved through digital tools such as BIM modeling and IoT monitoring. Case studies have shown that this model can improve plant survival rates by over 20% and achieve a water-saving efficiency of 75%, providing a replicable innovative paradigm for urban landscaping projects and helping to achieve the "dual carbon" goals and improve urban ecological quality.

Against the backdrop of increasing global environmental awareness and resource constraints, the traditional paper industry is facing challenges such as high energy consumption, high pollution, and resource waste, making green transformation an inevitable trend. This article focuses on green papermaking technology and resource recycling, systematically sorting out core technology paths such as clean production, waste paper regeneration, and biomass energy substitution, and analyzing their application modes in pulp making, de ink, water circulation, and energy cascade utilization. By comparing the environmental benefits and economic efficiency of traditional processes and green technologies, the significant advantages of green papermaking technology in reducing pollutant emissions (such as COD and SO ₂), reducing carbon emissions, and improving resource utilization have been revealed. Based on industry practice cases, this study proposes strategies to optimize the waste paper recycling system, overcome key technological bottlenecks, and improve policy incentives, providing theoretical references and practical paths for promoting low-carbon and circular development in the paper industry, and helping to achieve synergistic improvement of environmental and economic benefits.

This article focuses on the safety management of equipment in non coal open-pit mines and systematically analyzes its optimization path. Research has shown that by integrating innovative technologies such as the Internet of Things, big data, and artificial intelligence, real-time monitoring of equipment operation data, fault prediction, and dynamic risk warning can be achieved, promoting the transformation of maintenance mode to "predictive maintenance"; By improving the safety management system throughout the entire lifecycle, establishing a hierarchical and classified training system, and strengthening the construction of safety culture, the professional competence and risk awareness of personnel can be enhanced; By building an intelligent security management platform, integrating equipment, environment, and personnel data, risk collaborative control and decision-making optimization can be achieved. The research conclusion shows that the collaborative efforts of technological innovation and institutional optimization can significantly reduce the rate of mine safety accidents, providing theoretical support and practical reference for industry safety production and intelligent transformation.

This article systematically analyzes the water quality characteristics of various types of wastewater generated by domestic waste incineration power plants, including leachate, domestic sewage, circulating cooling wastewater, and workshop cleaning water. Through practical exploration and technological innovation, a disposal mode combining qualitative treatment and comprehensive utilization is adopted: using clear liquid as circulating cooling water replenishment to achieve resource utilization; Centrifuge, dehydrate, dry and incinerate the sludge for disposal; The concentrated solution is then sprayed back into the furnace or used for lime slurry preparation, converted into fly ash, and safely buried after chelation stabilization treatment. As a result, the entire factory's wastewater ultimately achieved the goals of comprehensive utilization and zero discharge. Finally, taking the Chaonan Municipal Solid Waste Incineration Power Plant (hereinafter referred to as "Chaonan Municipal Solid Waste Power Plant") in Shantou City as a case study, the practical application of comprehensive utilization and zero discharge of wastewater from the municipal solid waste incineration power plant is specifically elaborated.
