Problems solved by technology

The seawater cooling water after circulation still has a relatively high temperature when it flows out of the cooling tower, which saves a large amount of waste heat resources. However, there are still no reports on the efficient use of this waste heat resources.

Embodiment 1

[0022] The method of culturing Kappa and Eucheuma seaweeds is:

[0023] (1)

[0024] Build four seawater aquaculture ponds around the power plant that uses the seawater cooling system to generate electricity, and use the cooled seawater of the power plant as the aquaculture water. The four aquaculture ponds are designed through cascades, and the aquaculture ponds designed through the cascades are "bow" shaped; bow" The opposite ends of the font-shaped culture pond are respectively set as water inlet and water outlet, and the circulating water in and out is as follows: figure 1 As shown, the layout is as figure 1 . Each breeding pond has a water depth of 1-3 meters and an area of ​​about 3,000 square meters.

[0025] (2) a plurality of movable raft frames are set in the culture pond, the length of a single raft frame is 5 meters, and the width of 5 meters is advisable. To be supported by buoyancy, the skeleton of the raft frame is constructed of bamboo or wood. Nylon ropes ...

Embodiment 2

[0030] (1) Select a power plant that uses seawater cooling system to generate electricity in the coastal area of ​​Weifang, and build 4 breeding ponds, each with an area of ​​about 3,000 square meters. The layout is as follows figure 1 .

[0031] (2) With foam as the buoyancy support and bamboo as the skeleton, build a movable raft frame with a length of 10 meters and a width of 10 meters. The distance between the ropes is 60 cm, and telescopic anchors are set at the four corners.

[0032] (3) Separate seedlings of Kappa genus and Eucheuma genus seaweeds and tie them to the nylon ropes of the raft, control the plant spacing to be 30 cm, and the water depth of the nylon ropes to be 20 cm.

[0033] (4) From the first ten days of November to the first ten days of July of the next year in Weifang area, select areas with different distances from the hot water outlet every week to measure the water temperature.

[0034] (5) From November to July of the next year, the temperature of...

Embodiment 3

[0036] (1) Select a power plant that uses seawater cooling system to generate electricity in the coastal area, and build 4 breeding ponds, each with an area of ​​about 3,000 square meters. The layout is as follows figure 1 .

[0037] (2) In the breeding pond, use foam as buoyancy support and planks as the skeleton to build a movable raft frame with a length of 20 meters and a width of 20 meters. The distance between the ropes is 50 centimeters, and telescopic anchors are set at the four corners.

[0038] (3) Separate seedlings of Kappa genus and Eucheuma genus seaweed and tie them on the nylon rope of the raft frame, control the distance between plants to be 25 centimeters, and the water depth of the rope is 30 centimeters.

[0039] (4) From the first ten days of November to the first ten days of July of the next year in Weifang area, select areas with different distances from the hot water outlet every week to measure the water temperature.

[0040] (5) From November to July...

Abstract

The invention belongs to the technical field of marine organism, and specifically relates to a method for culturing Kappaphycus and Eucheuma alga by using cooling water of a power plant. The method uses cooling water waste heat of a power plant, and through arranging culture ponds connected in series in a stepped manner, establishing a moving raft frame, controlling the distance between a culturing raft frame and a hot water outlet, controlling alga culturing depth, and ensuring temperature of cultivation water where the alga is in between 18 and 30 DEG C, the method achieves an objective of conserving seedlings of the Eucheuma alga in northern china in winter. The method uses the power plant cooling water waste heat, and ensures to conserve seedlings and expand propagation of Eucheuma alga in northern china in winter, so as to realize year-round culture of the Eucheuma alga in northern china.

Description

technical field [0001] The invention belongs to the technical field of marine organisms, and in particular relates to a method for cultivating seaweeds of the genus Kappa and Eucheuma by utilizing the cooling water of a power plant. Background technique [0002] Seaweeds of the genus Kappa and Eucheuma are the main raw materials for the production of carrageenan in the world, and the seaweeds of the genus Eucheuma can be eaten directly as instant cold dishes with good taste and good economic value. Beginning in the 1970s, tropical countries in Southeast Asia (Philippines, Indonesia, Malaysia) began to artificially cultivate these two types of seaweed. At present, only a small part of these two types of seaweed raw materials come from wild seaweeds in tropical marine natural habitats such as coral reefs, and most of these two types of seaweed raw materials used on the market come from artificial cultivation. Therefore, artificial large-scale cultivation of seaweeds of the ge...
