Fuente: WIPO "dairy products" The invention relates to a flushing water recycling system and a flushing water recycling method, and relates to the technical field of flushing water recycling and reusing in the production process of dairy products. The system comprises key components such as a raw water storage tank, an alkaline water storage tank, an acid water storage tank, a waste water recovery tank, an alkaline water recovery tank, an acid water recovery tank and a recovery neutralization tank, and the key components are communicated with a pipeline needing to be washed through valves. A staged flushing strategy is adopted, and a real-time water quality detection and intelligent classification technology is combined, so that the quality and safe reutilization of recycled water are ensured, the water consumption in the dairy product production process is remarkably reduced, the wastewater discharge is reduced, the green and environment-friendly concept is met, and meanwhile, the operation cost of an enterprise is reduced.
