Mariculture pool with efficient pollution discharge function

Abstract

The invention relates to the field of mariculture, and discloses a mariculture pond with an efficient pollution discharge function, comprising a culture pond body and a sewage purification device arranged around the culture pond; the sewage purification device comprises a sludge treatment bin, a sewage purification bin and a water storage bin; a sludge accumulation bin is arranged at the bottom of the breeding pool body, a sludge treatment bin is arranged on one side of the breeding pool body, and the sludge treatment bin is communicated with the sludge accumulation bin through a first pipeline; the upper end of the sewage purification bin is communicated with the sludge accumulation bin through a second pipeline, and the lower end of the sewage purification bin is communicated with the water storage bin through a third pipeline. The process is simple and practical, that is, metabolic sediments deposited at the bottom of the pond are pumped out and filtered, meanwhile, purification treatment of removing nitrogen and phosphorus is carried out on water, then proper oxygenation is carried out, and finally, the water is conveyed into the pond again, so that a whole set of efficient pollution discharge method integrating impurity removal, purification, oxygenation and circulation is completed.

Description

technical field [0001] The invention relates to the field of mariculture, in particular to a mariculture pool with an efficient sewage discharge function. Background technique [0002] The objects of mariculture are mainly fish, shrimps and crabs, shellfish, algae and other economic animals such as sea cucumbers. Mariculture is an important part of the aquaculture industry. my country has a long history of marine aquaculture. Oyster farming was carried out as early as before the Han Dynasty, and the method of cultivating pearls was invented in the Song Dynasty. In recent years, my country's mariculture has developed rapidly, especially the development of main economic species such as kelp, laver, mussels and prawns, which has driven the development of coastal economy and has become a major industry in coastal areas. The advantages of mariculture are: concentrated development of fish, shrimp, shellfish and echinoderms (such as sea cucumbers) with high economic value, short ...
