Long-chain dicarboxylic acid circulating water tap water replenishing system

The utility model provides a long-chain binary acid circulating water tap water replenishing system which comprises a circulating water pool, a tap water replenishing pipeline and a circulating water pump, the circulating water pump is installed on a water outlet pipeline of the circulating water pool, and circulating water is conveyed to a fermentation tank and other water consuming equipment. A water outlet of the tap water replenishing pipeline is located at the front end of a water inlet of the water outlet pipeline, and tap water replenishing water and water in the circulating water pool enter the water outlet pipeline together. According to the long-chain dicarboxylic acid circulating water and tap water replenishing system, the consumption of tap water in production is reduced, the production cost of long-carbon-chain dicarboxylic acid is reduced, tap water is directly replenished to the water inlet of the circulating water pump in the circulating water pool through a pipeline, and the temperature of t
