Example Embodiment
[0020] A land-based pond system with the functions of purifying aquaculture discharge water and aquaculture, includes a land-based pond culture area 1, a land-based pond inlet ditches 2, a land-based pond drainage ditches 3, and a purified aquaculture pond 4.
[0021] 1. Land-based pond culture area
[0022] The land-based pond culture area 1 is mainly composed of land-based ponds for aquatic products such as shrimps, crabs, sea cucumbers, fish, and shellfish, such as figure 1 As shown, there are 10-20 breeding ponds, a single breeding pond area is 100-200 mu, and the daily exchange water volume of the land-based pond breeding park is 0.4-0.6%, preferably 0.5%.
[0023] 2. Land-based pond inlet ditches
[0024] The land-based pond inlet ditches 2 are connected to each breeding pond to provide breeding water for the breeding ponds. The main body is river channels or artificially excavated water channels. The total length can be 1000-2000 meters and the width is about 10 meters. For the...
