Shrimp culture tail water ecological treatment system

Abstract

The invention provides a shrimp culture tail water ecological treatment system. The system comprises a culture pond system for shrimp culture, a sedimentation pond for removing solid particles from culture tail water discharged from the culture pond system by sedimentation, a filter pond for filtering the solid particles in the culture tail water and subjected to sedimentation treatment in the sedimentation pond, an aeration pond for aeration treatment of the culture tail water filtered by the filter pond, a wetland system using plants and animals to remove harmful substances and algae in theculture tail water subjected to the aeration treatment in the aeration pond and a UV disinfection well for killing bacteria in culture tail water for purification of the wetland system. The system canachieve ecological treatment and recycling of the culture tail water, monitor the water purification degree in real time and effectively improve the water purification effect, and is low in cost andconvenient to operate and manage.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological treatment system for prawn breeding tail water. Background technique [0002] In the process of aquaculture, high-density shrimp farming will produce aquaculture tail water containing a large amount of feces and residual bait. Not only will there be a large amount of residual bait, excrement, biological corpses, etc. Toxic and harmful inorganic substances such as ammonia nitrogen, hydrogen sulfide, nitrous acid, etc., COD in water is as high as 200PPM. Such tail water is directly discharged into agricultural rivers, causing the fish and shrimp in the river to die in large numbers due to lack of oxygen, or a large amount of toxins will remain in the fish and shrimp in the river. If people eat these toxins, these toxins will be transferred to the human body, causing harm great harm. The above-mentioned aquaculture tail water has caused great harm to ...

AI Technical Summary

Problems solved by technology

For example: method 1) can reduce the soluble harmful components (ammonia nitrogen, nitroso salt, etc.) At the same time, fish and shellfish themselves must discharge certain metabolic waste; method 3) and method 4) can remove most of the suspended matter, but cannot reduce the soluble harmful components in the aquaculture water

Moreover, the current cost of treating aquaculture water is always too high, including device costs, which limits technology promotion
