The invention provides a pulp storage pool which comprises a pulp storage pool body, a settling pond and a motor arranged at the bottom end of the pulp storage pool body. Double layers of filtering screens are fixedly arranged in the pulp storage pool body, activated carbon particles are fixedly arranged between the double layers of filtering screens, and the motor is fixedly connected with a rotary shaft. Blades are fixedly arranged on the rotary shaft, and the settling pond is fixedly connected with the middle of the pulp storage pool body through a water conveying pipe. The pulp storage pool is simple in structure and high in practicality, the motor is arranged and drives the blades to rotate, pulp is stirred, production is convenient, and the production efficiency is improved. The settling pond is arranged, the pulp settles through the settling pond, then supernate of the settling pond is conveyed into the pulp storage pool body through a pump on the water conveying pipe for recycling, the cost is reduced, and materials are saved. Meanwhile, circulating water flow is formed on a water conveying opening, paper can be prevented from precipitating, and it is avoided that the quality of the paper is influenced. The activated carbon particles are arranged, impurities in the pulp can be adsorbed, and the quality of the paper can be better.
