Water is the source of life, an essential element in production, and the foundation of ecosystems. In the natural hydrological cycle, water that can be utilized by humans is referred to as water resources. Water resources form the basis for human survival and development, intimately connected to daily life, and concurrently represent a controlling factor in the ecological environment. It is well-known that the thermal power generation industry has consistently been a major consumer of water in the industrial sector, with substantial demands for water resources. Throughout the process of thermal power generation, water resources are extensively utilized for cooling, steam generation, waste heat discharge, and other processes. This large-scale utilization of water resources not only imposes pressure on local water resources but also leads to pollution of water environments and disruption of ecosystems.To address the challenges posed by the limited availability of water resources and environmental pollution, this paper explores the key technologies for optimizing water systems in thermal power plants. Through in-depth analyses of 3S water source optimization technology, ABFT biological treatment processes, recycled water utilization technology in the circulating cooling system, reclaimed water reuse technology, and the coal-fired "flue gas desulfurization" process, coupled with empirical studies of typical cases, the aim is to propose viable optimization solutions for water systems.
