Three-stage water purification system for aquaculture

Abstract

The invention relates to the technical field of water purification, in particular to a three-stage water purification system for aquaculture. The three-stage water purification system comprises a sedimentation purification tank; the sedimentation purification tank is provided with a biological purification layer, an aquatic plant purification layer and a physical purification layer sequentially from top to bottom; at least one biological purification box is arranged in the biological purification layer; the biological purification box comprises a box body; a base plate is mounted at the bottomof the box body; the box body is provided with an agent adding zone, a mother liquor preparation zone and a biological culture zone sequentially from top to bottom; an agent inlet pipe communicatingwith the interior of the box body is mounted at the top of the box body; and a water drain port communicating with the interior of the box body is formed in one side, close to the bottom of the biological culture zone, of the box body. In the three-stage water purification system for aquaculture, the biological purification layer is arranged to carry out effective biological purification on culture tail water, the aquatic plant purification layer is arranged to perform plant purification on the culture tail water and increase the oxygen content of water, and the physical purification layer isarranged to conduct primary physical purification on the culture tail water and effectively cultivate bacteria.

Description

technical field [0001] The invention relates to the technical field of water body purification, in particular to a three-stage water purification system for aquaculture. Background technique [0002] Aquaculture is the use of waters available for breeding (including planting) by human beings. According to the ecological habits of the breeding objects and the requirements for the environmental conditions of the waters, aquaculture technology and facilities are used to engage in aquatic economic animal and plant breeding. When carrying out aquaculture The requirements for water quality are particularly important. These have become more concerned issues for farmers. The existing water purification methods can only remove impurities in the water source, but cannot enhance the nutrition in the water source. As a result, after the water source is purified, it is necessary to add fertilizer and water to maintain purified water. It contains nutrients inside and is expensive to prod...

These have become more concerned issues for farmers. The existing water purification methods can only remove impurities in the water source, but cannot enhance the nutrition in the water source. As a result, after the water source is purified, it is necessary to add fertilizer and water to maintain purified water. Contains nutrients inside and is expensive to produce

In the process of shrimp and crab breeding, it is often faced with the occurrence of a large number of deaths due to factors such as pulling the top shell and failing to molt, which affects the final output.

Not only that, the occasional occurrence of river crab white paste disease, water slug disease, and prawn death disease also seriously affects the production of aquaculture.
