Overview of Distributed Integrated Recirculating Aquaculture System

Key words

Distributed: Each breeding unit has independent breeding and water purification functions, which can effectively avoid the risk of cross infection;

Integration: integrate multiple functions into one device, such as the growth pond of the breeding unit and the function of water purification;

Recirculating aquaculture: through water purification technology and aquaculture technology, Realize no water change, less water change for fish and other aquatic animals, and realize high-density breeding or temporary breeding.

System composition：

Each breeding system is composed of multiple breeding units, and each breeding unit is composed of a multifunctional growth tank，tomatic water filter and micro-nano solid-liquid separator.

System functions：

Recirculating aquaculture and temporary breeding.

系统原理：

养殖单元分内外仓，外仓为生长区，内仓为水质净化区。生长区为对称锥底结构，在水体旋流的情况下，可最大化自生的排污能力。通过循环过滤和水质净化实现循环水养殖。多个养殖单元组成完整的分布式养殖系统

System principle:

The breeding unit is divided into inner and outer warehouses, the outer warehouse is the growth area and the inner warehouse is the water purification area.

The growth zone has a symmetrical cone bottom structure, which can maximize the self-generating sewage discharge capacity in the case of water swirling.

Realize circulating aquaculture through circulating filtration and water purification. Multiple breeding units form a complete distributed breeding system.

1、优异的排污能力（光滑锥形底结构）；

2、 独立的水质净化单元（可有效降低水体中氨氮、亚硝酸盐等有害物质的浓度），同时避免交叉感染，降低养殖病害风险；

 3、内部氧气仓的氧气缓慢释放可降低缺氧风险；

4、工厂内组装，实现设备地面快速安装即可使用，无需大量的土建，地下埋管等工作，便于维护管理；设备由高强度复合塑料成型，耐酸碱抗紫外线，寿命长，具有可靠的运行能力；

5、产量更高、维护管理成本更低；

6、有较高的剩余价值，可多次拆卸转移利用。

Main characteristics

1.Excellent drainage capacity (smooth conical bottom structure)

2.Independent water purification unit (which can effectively reduce the concentration of harmful substances such as NH3-N and nitrite in the water body), while avoiding cross-infection and reducing the risk of breeding diseases.

3.The oxygen in the internal oxygen tank will be released slowly, which can reduce the risk of hypoxia.

4.The equipment is assembled in the factory,it can be used after being quickly installed on the ground,withuot a lot of civil engineering and underground pipe work.It is convenient for maintenance and management. The equipment is made of high strength composite plastics, acid and alkali resistant, UV resistant and long service life. The equipment has reliable operation ability.

5.Higher aquaculture production and lower maintenance and management costs.

6.The equipment has high residual value and can be disassembled and transferred for multiple times.

1、 鱼池底部要有一定的坡度，对称锥形底排污效率最大；

2、 鱼池内部水的流动，旋转流动可以将食物残渣及粪便集中到中心点向下排出，合适的旋流速度排污效率最大； 

3、  鱼池内壁一定的光滑度，越光滑越有利于排污；

4、 采用好的过滤器并增加循环过滤次数。

      本设备同时具备排污主要条件前三点的能力，还具备独立的净化水质能力，充氧固氧能力，这也是本设备区别于其他设备的重要优势。

The main conditions for achieving maximum efficiency of sewage discharge in the breeding pond

1. The bottom of the fish pond must have a certain slope, and the symmetrical cone bottom has the greatest sewage efficiency.

2.The flow of water inside the fish pond, the rotating flow can concentrate the food residues and feces to the center point and then discharge it downwards, and the proper swirling speed has the greatest sewage discharge efficiency.

3.The inner wall of the fish pond has a certain smoothness. The smoother the inner wall, the more conducive to sewage discharge.

4.Adopting a good filter will increase the number of cycle filtering.

This equipment also has the ability to discharge the main conditions 1 to 3, and also has independent water purification capabilities, oxygenation and solidification capabilities.It is also an important advantage of this equipment different from other equipment.
