A marine aquaculture pond with efficient sewage discharge function

Abstract

The invention relates to the field of mariculture, and discloses a seawater aquaculture pool with high-efficiency sewage discharge function, comprising a culture pool body and a sewage purification device arranged around the aquaculture pool; The bottom of the aquaculture tank body is provided with a sludge accumulation bin, and one side of the aquaculture tank body is provided with a sludge treatment bin, and the sludge treatment bin and the sludge accumulation bin are connected through a first pipeline; the upper end of the sewage purification bin is connected with the sludge accumulation bin. The silo is communicated through a second pipeline, and the lower end of the sewage purification silo is communicated with the water storage silo through a third pipeline. The process of the invention is simple and practical, that is, by extracting and filtering the metabolic sediment deposited at the bottom of the pool, simultaneously purifying the water to remove nitrogen and phosphorus, and then properly oxygenating it, and finally retransmitting the water to the pool, so as to complete the process. A complete set of high-efficiency sewage methods integrating impurity removal, purification, oxygenation and circulation.

Description

technical field [0001] The invention relates to the field of mariculture, in particular to a mariculture pool with efficient sewage discharge function. Background technique [0002] The objects of marine aquaculture are mainly fish, shrimps and crabs, shellfish, algae and other economic animals such as sea cucumbers. Marine aquaculture is an important part of aquaculture. my country has a long history of marine aquaculture. As early as before the Han Dynasty, oyster culture was carried out, and the method of cultured pearls was invented in the Song Dynasty. In recent years, my country's marine aquaculture has developed rapidly, and the development of major economic species such as kelp, seaweed, mussels and shrimp is particularly prominent, which has driven the development of coastal economy and has become a major industry in coastal areas. The advantages of mariculture are: focus on the development of some fish, shrimp, shellfish and echinoderms (such as sea cucumber) wit...
