Hefei is a city far from the sea. It is difficult to build such a large ocean world, so many sources of seawater become a problem. Because the use of seawater is too expensive, the seawater of Hefei Ocean World is salinized with fresh water, and the ratio of seawater to fresh water is 1:33. Hefei Hanhai Polar Ocean World has sent experts to study and monitor the proportion of seawater to achieve the best seawater effect. Ocean World has a complete set of water recycling system. The whole Hefei Aquarium needs 4500 tons of seawater and fresh water, and the proportion of seawater is expensive. Water alone is as high as 500,000 to 600,000 yuan. So after the aquarium is completed, water will not be wasted at all. Areas that need to be replaced with water will pass through the circulation system and be reused after treatment.
Going to "Sea World" to see fish is also to see people. This person refers to the "mermaid". The "Mermaid" who will dance with sharks in Hefei Sea World is a girl selected from Hefei. Both of them are about 20 years old and have received strict training in Nanjing. On the one hand, they practice swimming in Nanjing Ocean World, on the other hand, they understand the habits of sharks. This is a challenging and dangerous job, but the shark's temper can be grasped and there are "signals" to follow.
