Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific examples.

[0037] like figure 1 , figure 2 and image 3 As shown, a section of sewage treatment pond is set at the periphery of the fish pond 1, and the sewage treatment pond is successively a sedimentation pond 4, a fine filter pond 5, a biological purification pond 8, a disinfection pond 11 and an air stripping pond 16 from front to back.

[0038] The height of the wall between the sedimentation tank 4 and the fine filter tank 5 is lower than the water level of the fish pond 1; the center of the bottom of the fish pond 1 is provided with a drain, and the drain is connected to the bottom of the sedimentation tank 4 through the drain pipe 2, The end of drainage pipe 2 is connected with vertical intubation pipe 7, and the outlet height of intubation pipe 7 is lower than the water level height in fishpond 1, and the periphery of intubation pipe 7 is nested with circular tube type draft ...

Abstract

The invention relates to an energy-saving air-lift recirculating aquaculture fish pond system, and belongs to the technical field of aquaculture equipment. A circle or section of sewage draining pond is arranged on the periphery of a fish pond and comprises a settling pond, a precision filter pond, a biological purification pond, a disinfection pond and an air-lift pond which are sequentially arranged from front to back, water in the fish pond enters a filter pond through a drain pipe, overflows into the precision filter pond after settling and filtering, and enters the biological purification pond from the bottom after being filtered by the precision filter pond, harmful substances such as ammonia nitrogen in the water are removed by means of biological degradation, the water overflows into the disinfection pond, and the disinfected water flows back to the fish pond after oxygen enhancement by an air-lift device. The energy-saving air-lift recirculating aquaculture fish pond system is small in occupied area, compact in structure, integrated in layout, low in investment, simple, low in aquaculture cost, excellent in water treatment effect and beneficial to popularization, and aquaculture scale and efficiency are improved.

Description

technical field [0001] The invention relates to an energy-saving air-lift circulating water culture fish pond system, which belongs to the technical field of aquaculture equipment. Background technique [0002] my country is a large aquaculture country and an important supplier of aquatic products in the world. However, the traditional extensive aquaculture method using scale expansion is currently facing enormous pressure from the environment, policy, society and other aspects. Therefore, it is of positive significance to widely promote the water-saving, land-saving and environment-friendly recirculating aquaculture system. At this stage, the recirculating aquaculture system can be roughly divided into two technical routes with obvious differences. One is the highly integrated recirculating aquaculture model, which mainly obtains good water quality through various water treatment equipment and reduces personnel through automated facilities. The labor intensity is low, and ...
