In-situ water purification equipment for pond culture

Background to the need.

Ponds provide a living environment for farming objects as well as a place for water quality control and bait culture, but in natural water bodies water quality control and bait culture are at a low level. The complex composition of the culture tailwater is difficult to achieve self-cleaning and standard discharge in the natural state, the application of traditional sewage treatment technology and oxygenation equipment is too low cost. At present, the centralized continuous pond culture tailwater ecological purification project can achieve the function of aquaculture and ecological protection, if promoted in South American white shrimp culture is facing high construction costs, occupying a centralized area, complex operation and maintenance problems, especially in the process of South American white shrimp culture disease prevention measures required, the water between the farm ponds can not be exchanged, the urgent need to develop the aquaculture production and water purification equipment applicable to independent ponds, in Shanghai shrimp aquaculture base for large-scale promotion.

Sustained maintenance of a good ecological environment in the culture process depends on maintaining all aspects of the material and energy cycle in the pond at a balanced level. The feeding of artificial baits under high-density culture changes the natural circulation state, which needs to be regulated by artificial reinforcement means of oxygenation, hydrodynamic and microbial feeding conditions. Combining the micro-nano aeration push flow device and and microbial reactor to form in-situ water treatment equipment, effectively enhances the hydrodynamic of the pond water body, rapidly increases the dissolved oxygen content, rapidly increases the number and activity of microorganisms in the water body, and greatly enhance the self-purification ability of the water body.

Need to develop low-cost, low-energy, good treatment effect of biological treatment equipment adapted to the characteristics of the South American white shrimp growth environment, based on the South American white shrimp aquaculture pond ecological factor changes in the law, combined with immobilized microorganisms and other water quality treatment technology to achieve in situ treatment of aquaculture water, to maintain the aquaculture process of the water environment in line with the geographical environment requirements of the green aquatic product certification.
