Circulating water treatment equipment for pond culture

Abstract

The invention discloses a circulating water treatment equipment for pond culture. The circulating water treatment equipment comprises a pond, wherein the water flow of the pond passes through a wateroutlet valve, sequentially passes through a transition tank, a purification tank and an aeration tank and flows back to the pond through a water pump, and a filtering mechanism located on one side ofthe water outlet valve is arranged in the pond. By arrangement of the filtering mechanism, at least two first filtering plates are mounted near the water outlet valve in the pond, so that impurities stay in different areas according to the sizes of the purities, and the condition that excessive impurities suspend on the side edges of the same first filtering plates to affect water flow movement isavoided; by arrangement of the purification pond, a floating bed can be mounted under the action of a filtering frame to form an ecological floating bed, root systems of aquatic plants are used to absorb harmful substances in water and purify water, in combination with buffer water flow of buffer slopes, and damage to the aquatic plants is reduced; and meanwhile, the two buffer slopes can lock water sources, so that when the pond is dry up, the water sources are ensured to remain at the bottom of the floating bed for normal growth of the aquatic plants.

Description

technical field [0001] The invention relates to the technical field of pond cultivation, in particular to a pond cultivation circulating water treatment equipment. Background technique [0002] With the rapid development of the aquaculture industry, the negative effects of blindly expanding the scale and investment are becoming more and more serious. In order to increase the output of aquatic products, a large amount of artificial bait is put into the aquaculture water body, causing serious water pollution. The pollution of aquaculture itself and the water environment The contradictions in the aquaculture industry are also becoming increasingly prominent, the aquaculture environment is deteriorating, and aquaculture biological diseases occur frequently; water environmental pollution not only restricts the healthy development of my country's aquaculture industry, but also has an important impact on the ecological environment of the aquaculture area and its adjacent waters. At p...

Problems solved by technology

[0003] The traditional water treatment device introduces the water flow into the sedimentation tank through the pipeline. During the water intake process, impurities are easy to accumulate in the water outlet, causing blockage and affecting the treatment work. After natural precipitation in the sedimentation tank, it is filtered and discharged through a mechanical filter plate. The function is single, and the filtering effect is not good, and the device cost is high, so there is an urgent need for a pond culture circulating water treatment equipment to solve the above problems
