Embodiment 1

[0028] A coating for inhibiting the growth of algae in hairy crab breeding ponds, the formulation of the coating is as follows: 0.5-5 parts of activated carbon, 0.5-4 parts of copper sulfate, 2-4 parts of copper oxide, 10-20 parts of acrylic resin, light calcium carbonate 5-8 parts, 1-4 parts of methyl cellulose, 1-3 parts of silicon dioxide, 1-6 parts of ethylene glycol, 8-12 parts of polyoxyethylene fatty alcohol ether, 2-4 parts of acrylic leveling agent, 6-8 parts of polydimethylsilane, 2-5 parts of BYK-W980 or BYK-W9650, 5-10 parts of water.

Embodiment 2

[0030] Adjust the content of activated carbon to be 0.5 part, 1 part, 2 parts, 3 parts, 4 parts, 5 parts, and the parts by weight of other substances are constant, and the coatings obtained are coated on the inner walls of 6 experimental pools respectively, so as not to be coated. The pool of paint is used as a comparison, and water from Yangcheng Lake is added, and the other treatments are the same, and the growth of algae in the pool is detected by OD value.

Embodiment 3

[0034] Regulating the content of copper sulfate is 0.5 part, 1 part, 2 parts, 3 parts, 4 parts, and the parts by weight of other substances are constant, utilize the coating that obtains to be coated on the inwall of 5 experimental ponds respectively, with the non-coated coating For comparison, the pool was added with water from Yangcheng Lake, and the other treatments were the same, and the growth of algae in the pool was detected by OD value.

Abstract

The invention discloses a water circulation purification system for artificially culturing hairy crabs. The system comprises a balancing pond, an activated carbon purifying pond, a corallite purifying pond, a bio-ball purifying pond and an impounding reservoir; the bio-ball purifying pond is internally provided with a biological cleaning ball, aerobic denitrifying bacteria are attached to the interior of the biological cleaning ball, and the aerobic denitrifying bacteria are ATCC 14581. The circulation system comprises the balancing pond, the activated carbon purifying pond, the corallite purifying pond and the bio-ball purifying pond, and the inner wall of each purifying pond is further coated with an algae control coating. The water circulation purification system for artificially culturing the hairy crabs can achieve the purposes of purifying water and controlling the growth of harmful microbes.

Description

technical field [0001] The invention belongs to the technical field of hairy crab artificial cultivation, and in particular relates to a water circulation purification system for artificial cultivation of hairy crabs. Background technique [0002] Hairy crabs are people's favorite delicacy. They are not only delicious but also have high nutritional value. At present, there are many varieties of hairy crabs. Most diners like wild hairy crabs because wild hairy crabs taste better and have higher nutritional value. However, wild hairy crabs are more expensive, and the quantity How to breed hairy crabs that are close to wild taste and nutritional value has always been the goal pursued by crab farmers. [0003] Hairy crabs, also known as Chinese mitten crabs, river crabs, hairy crabs and clear water crabs, are special products in China. They are delicious in meat and rich in nutrition. They are aquatic treasures. The large-scale breeding of hairy crabs in China began in the 1970...
