Abstract

Under the background of global water shortage and increasingly serious environmental pollution problems, the efficient and environmentally friendly utilization of industrial cooling circulating water has become the key to realize industrial sustainable development. In this paper, the problems, present situation and development trend of "zero emission" technology for water saving and environmental protection of industrial cooling circulating water are deeply discussed. The research points out that although the technology faces many challenges in water quality treatment, energy consumption control, technology integration, investment cost and maintenance management, it is expected to gradually overcome these challenges through technological innovation, policy support and market promotion. This paper analyzes the problems encountered in the practical application of the existing technology, such as scaling corrosion, chemical pollution, high concentration multiple operation risk and the high cost and complexity of the new water-saving technology, and puts forward corresponding countermeasures and suggestions. In terms of technical development trend, intelligent monitoring and control system, high-efficiency water-saving technology, optimization of bypass filtration technology and expansion of application scope of closed cooling circulation system will become the focus of future research. At the same time, the breakthrough of "zero emission" treatment technology, such as the progress of membrane concentration and evaporation concentration technology, will also promote the development of industrial cooling circulating water treatment in the direction of high efficiency and low energy consumption. The research in this paper provides strong theoretical support and practical guidance for industrial water saving, environmental protection and sustainable development, aiming at promoting the wide application of "zero emission" technology and helping the green transformation of industrial production.
