The utility model discloses a low-carbon circulating flow aquaculture system, which comprises a main aquaculture pool, a pollution collecting buffer pool, a purification pool and a control unit. The main aquaculture pool is a cylinder, the bottom of the pool is a cone or an arc, and the bottom of the pool is connected with a pollution collecting buffer pool through a connecting pipe, an oxygen-increasing and water-pushing device is arranged in the main aquaculture pool, and the pollution collecting buffer pool is a CY The bottom is connected with the purifying pool through the pipeline, the purifying pool is connected with the main nutrient pool through the pipeline, and the control valve is arranged on the pipeline, and the control unit is connected with the control valve and the oxygen-increasing water pushing device; the area of the purifying pool is 2-10 times of the main nutrient pool. The utility model has a reasonable pool body design, and the main pool body adopts a cylindrical body, which is beneficial to the circulating flow of the pool water body; and among the three pools, only the investment of the main pool is needed, and the overall construction cost is only one third of the existing ones. The use of the difference between the three pools reduces the energy consumption of sewage discharge, and the adoption of large-area purification pools to achieve zero discharge.

一种低碳循环流水养殖系统
本技术涉及一种低碳循环流水养殖系统,属于渔业养殖
技术介绍
目前市场上推广的池塘低碳循环流水养殖模式主要是美国大豆协会研发推广的长方形池塘循环流水养殖模式。该模式通过建设3组5×22×3米长方形水泥池用于集中养殖,池尾配套建设一组集污池,配套大塘进行水质净化,通过增氧、推水、排污,实现低碳循环流水养殖。但是,通过2016年~2017年推广该模式的案例总结,成功案例占比极少,多数为亏损,养殖风险比例加大。总结该模式存在的缺陷如下:建设成本高(一套养殖实施建设成本在25~30万元);养殖风险大(高密度养殖下,鱼类易发生应激反应,死亡率高),一般养殖户难以承受;排污不方便、排污效果不佳,需要专用吸污机械进行吸污、排污,且消耗大量人力、物力、财力,排污时间长,养殖成效不佳。
