Abstract

The invention discloses an aquaculture net cage with a water circulation filter device. The cage comprises floating platforms, filter components, a plurality of first water pipes, a plurality of second water pipes, a plurality of first filter nets, water outlets and second filter nets; an inner layer net cage body and an outer layer net cage body which are sleeved with each other are arranged below the floating platforms; the filter components comprise a plurality of water inlets; the first filter nets are arranged on the cross sections of the first water pipes; the water outlets are formed in the floating platforms and formed in the connection portion close to the outer layer net cage body and the floating platforms, and the lower edges of the water outlets are higher than the water surface outside the side wall of the outer layer net cage body; the second filter nets are arranged in the water outlets. According to the aquaculture net cage with the water circulation filter device, the outer layer net cage body controls the circulation of the water body in a semi-closed mode, the effective filter components are arranged, meanwhile it is guaranteed that the water quality of the aquaculture water body in the inner layer net cage body and the water body outside the outer layer net cage body is always kept in a good state, and the pollution of the water body is avoided.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquatic product culture cage with a water circulation filter device. Background technique [0002] As the scale of fishery and aquaculture continues to expand, metabolites and residual bait organic matter increase sharply, and untreated aquaculture sewage is directly discharged, causing great pollution and damage to environmental waters. [0003] For this reason, the recirculating aquaculture system integrating many technologies has become an important research direction for the sustainable development of aquaculture due to its own characteristics. The basic water treatment process used in this breeding system, because the process includes physical filtration, biological treatment, oxygenation and other links, the process is complicated and the investment in facilities and equipment is large; and the water cycle process is all mechanically driven, and the energy consumptio...
