Embodiment 1

[0037] Embodiment 1: the sewage treatment of separate discharge

[0038] The inventor purchased from Hainan on May 10 and May 14 3 million Penaeus vannamei fingerlings with an average body length of 4-5mm, a total of 6 million tails, and put them into two 1000m 2 Temporary breeding and standardization are carried out in the high level pond, and the average stocking density is 3000 fish / m 2 , the water depth of the high-level pool is 2m, and each high-level pool is equipped with four 1.5-kilowatt waterwheel aerators, and the two pools share one 4-kilowatt microporous aerator. Mainly feed prawn standard coarse special feed and 1 # Broken material, feeding 3-5g / 10,000 fish per day in the early stage, gradually increasing with the growth of prawns, and constantly adjusting according to the weather and feeding conditions of prawns, until June 10 when the ponds were divided, and the daily feeding amount increased to 100-120g / 10,000 At the end of the day, 2300kg of compound feed wa...

Embodiment 2

[0040] Embodiment 2: primary biological purification tank purification effect (enteromorpha purification effect)

[0041] The inventor purchased from Hainan on May 10 and May 14 3 million Penaeus vannamei fingerlings with an average body length of 4-5mm, a total of 6 million tails, and put them into two 1000m 2 Temporary breeding and standardization are carried out in the high level pond, and the average stocking density is 3000 fish / m 2 , the water depth of the high-level pool is 2m, and each high-level pool is equipped with four 1.5-kilowatt waterwheel aerators, and the two pools share one 4-kilowatt microporous aerator. Mainly feed prawn standard coarse special feed and 1 # Broken material, feeding 3-5g / 10,000 fish per day in the early stage, gradually increasing with the growth of prawns, and constantly adjusting according to the weather and feeding conditions of prawns, until June 10 when the ponds were divided, and the daily feeding amount increased to 100-120g / 10,000 ...

Embodiment 3

[0045] Embodiment 3: micro-ecological purification pool treatment effect

[0046] The micro-ecological purification reservoir is 8 mu. Install 2 sets of 3 kW impeller aerators for violent gas. In mid-May, when the water temperature reaches above 25°C, Bacillus subtilis (1.5×10 -6 ), Lactobacillus (6×10 -6 ), EM bacteria (6×10 -6 ), the aerator is turned on for more than 15 hours a day. The various water quality indicators are shown in Table 2 below. After the water quality reaches the standard, it can be reused to realize the recycling of the aquaculture water, realize the closed cycle shrimp cultivation of seawater aquaculture, and ensure the safety of the aquaculture water.

Abstract

The invention discloses a seawater circulation culture system with circulation water treatment; the seawater circulation culture system comprises a culture pond, a sewage discharge port, a sewage discharge pipe; the bottom of the culture pond is provided with the sewage discharge port connected with the sewage discharge pipe; the system also comprises a sewage discharge mechanism and a circulation water discharge mechanism; the sewage discharge pipe is connected with the sewage discharge mechanism and the circulation water discharge mechanism through a tee joint; the circulation water discharge mechanism is connected with a circulation water processing mechanism comprising an oxidation water reservoir, a primary biological cleaning pond and a micro-ecology cleaning pond; tail water is discharged into the oxidation water reservoir through the circulation water discharge mechanism, fully oxidized and settled, and enters the primary biological cleaning pond; the water is cleaned by the biological cleaning pond and enters the micro-ecology cleaning pond for micro-ecology treatment; the water will be reused after water quality reaches the standards, thus realizing culture water full circulation usage. The seawater circulation culture system is low in cost, simple in operation, easy to promote, high in efficiency, and can provide important meanings for protecting sea environment and aquatic product safety production.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a seawater circulation aquaculture system with circulating water treatment. Background technique [0002] With the improvement of people's living standards, aquatic products are more and more popular among people. Aquatic products such as fish and shrimp have gradually become indispensable delicacies on the table because of their delicious taste and high nutritional value. With the development of high-level pond aquaculture, the high-level pond recirculating aquaculture model not only makes full use of land and water resources, but also reduces environmental pollution and greatly increases pond productivity. [0003] my country is the country with the largest aquatic product breeding area and the highest output in the world. And with the continuous expansion of aquatic product breeding area, the coastal aquatic product breeding industry is growing day by day. How...
