Land-based pond system with functions of purifying breeding drained water and breeding

Abstract

The invention discloses a land-based pond system with functions of purifying breeding drained water and breeding. The land-based pond system comprises a land-based pond breeding area, a land-based pond water inlet ditch, a land-based pond water draining ditch and a purifying breeding pond, wherein the land-based pond breeding area is taken as a breeding main body; water is charged through the land-based pond water inlet ditch, and drained through the land-based pond water draining ditch; the tail end of the land-based pond water draining ditch is connected with the purifying breeding pond; the purifying breeding pond is partitioned into a foam separating and ecological purifying area, a purifying breeding area and a sediment area according to different purifying functions; the foam separating and ecological purifying area is provided with a foam separator and an ecological purifying pond which are connected in sequence. By adopting the land-based pond system, ecological complementation among bred organisms is fully utilized, an ecological repairing and self-cleaning function acting inside a mode system is brought into play by adjusting a breeding production mode, self-purification of breeding drained water in the system is realized, and pollution on an external environment caused by breeding is lowered.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a land-based pond system with the functions of purifying aquaculture discharge water and aquaculture. Background technique [0002] Land-based marine aquaculture is an important development mode of marine fishery in my country. As of 2010, only Shandong Province had a seawater pond aquaculture area of ​​112,500 hectares and an output of 275,200 tons, accounting for 22.45% and 6.95% of the province's total seawater fishery area and total output, respectively. In recent years, the land-based seawater pond aquaculture industry has achieved rapid development. The land-based pond aquaculture of famous and high-quality aquatic products such as seawater shrimp, crabs, sea cucumbers, and shellfish has become an important pillar industry for the development of the marine economy. [0003] At present, the main production mode of land-based seawater pond aquaculture is exte...

AI Technical Summary

Problems solved by technology

[0003] At present, the main production mode of land-based seawater pond aquaculture is extensive monoculture or polyculture. Disorderly competition in the industry leads to one-sided pursuit of production and excessive reliance on bait input, resulting in a decline in water quality in various aquaculture ponds, a decrease in dissolved oxygen, and a large increase in nitrogen and phosphorus content. Exceeding the standard; a large amount of wastewater from aquaculture ponds is discharged, which not only pollutes the marine environment, but also causes self-pollution of the aquaculture ponds, resulting in a vicious circle. These phenomena seriously restrict the sustainable development of the land-based seawater pond aquaculture industry
