Abstract: With the continuous implementation of the strictest water resource management system, new requirements have been put forward for water-saving work in paper-making enterprises. It is urgent to carry out water balance testing to deeply explore the water-saving potential of enterprises. This article proposes a water balance testing method for paper-making enterprises, divides the testing units, and studies the water-using situation and level of the enterprise based on the measured results. Present problems are identified, and targeted improvement measures are proposed. The results show that:1)The efficiency of the paper-making water process equipment is advanced compared with that of the same industry, the systems are functional, and the water meters for measurement are equiped complete. 2)All the indicators of water intake per ton of kraft cardboard, water reuse rate, indirect cooling water circulation rate, condensate water reuse rate, and standard discharge rate, all fit in the “Guidelines for the Evaluation of Water saving Enterprises”. Mentioned indicators are at an upper-middle level among similar enterprises. The research results can provide effective suggestions for paper-making enterprises to tap into water-saving potential, improve water efficiency, and optimize management.
