Embodiment 1
[0029] A breeding base in Yuhang District, Hangzhou City used a device based on electrolysis of the present invention for water quality purification of pond circulating water to purify 30,000 perch for 4 months in pond circulating water. Compared with the past breeding records of the base (aeration and oxygenation water pushing machine), the survival rate of cultured perch using the present invention is increased by 10-20%, the feed coefficient is reduced by 3-5%, and the body weight of the fish is increased by 3-5%.

The invention discloses a pond circulating water quality purification plug flow aeration device based on electrolyzed water and a setting method of the device. The device comprises a pipeline, a mainpipeline, a proportional dilution pump and a plurality of jet devices; the pipeline is communicated with the main pipeline, a water inlet of the pipeline achieves feeding of aquatic water through an external water pump, the proportional dilution pump is arranged on the pipeline and is used for integrating the electrolyzed water into the aquatic water; the jet devise are evenly distributed on the main pipeline and communicated with the main pipeline and are used for ejecting water flow. In addition, the setting method is specifically applied in a pond circulating water system, the top end of each water running tank is provided with a plug flow aeration device body, the tail of a runway tank is provided with a plug flow aeration device, the top of a check dam is provided with a plug flow aeration device, and the plug flow aeration devices are distributed in the outflow direction of the water flow clockwise or anticlockwise. The pond circulating water quality purification plug flow aeration device can be conductive to the aeration of pond circulating water, reduce the noise, and improve the water quality safety.
Description
technical field [0001] The invention belongs to the technical field of circulating aquaculture, and relates to an electrolytic water-based plug-flow oxygenation device and a setting method for pond circulating water purification. Background technique [0002] The pond recirculating aquaculture model is a kind of model that learns from the concept of factory recirculating aquaculture, transforms the "open free-range culture" of traditional ponds into "intensive captive culture", and combines a variety of bioremediation technologies with pond engineering transformation methods. A new type of pond circulating water ecological farming model. The dissolved oxygen content in the water body and the water quality environment are two key factors that determine the aquaculture density per unit water body, and the pond recirculating aquaculture has the characteristics of high aquaculture density per unit water body, so increasing the dissolved oxygen content in the water body is the ke...
