Aquaculture wastewater circulating treatment system

Abstract

The invention discloses an aquaculture wastewater circulating treatment system. The circulating treatment system comprises a precipitation device, a biochemical treatment device, a flocculation device, a disinfection device and an oxygenation device. The precipitation device can slowly and effectively collect wastes so as not to shake the wastewater on the upper layer of a precipitation tank as much as possible; and wastewater on the upper layer of the settling tank can be quickly and effectively overflowed into a treatment tank. According to the biochemical treatment device, a biochemical membrane can be conveniently replaced, and wastewater entering the treatment box can be stirred, so that the wastewater is in full contact with the biochemical membrane. The flocculation device can be used for effectively collecting flocculated wastes and also can be used for fully flocculating the wastewater entering a flocculation tank. A disinfection bag can be conveniently replaced through the disinfection device, and it can be guaranteed that waste water entering the disinfection box can be fully disinfected. Aquaculture wastewater is subjected to precipitation treatment, biochemical treatment, flocculation treatment, filtration treatment, disinfection treatment and oxygenation treatment and then is recycled for aquaculture, so that the utilization rate of water resources is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture wastewater treatment, and more specifically relates to an aquaculture wastewater circulation treatment system. Background technique [0002] Aquaculture is an important part of agricultural production, generally including the whole process of growing aquatic products from seedlings under artificial breeding management. However, the use of a large amount of materials, fertilizers and chemicals has brought enormous pressure to the aquaculture water body, and a large amount of organic matter cannot be completely decomposed, causing water pollution. [0003] At present, the treatment of aquaculture wastewater is usually to inject the wastewater into a fresh water body after the wastewater is completely discharged, and the wastewater is not recycled after effective treatment, thus causing a waste of water resources. Contents of the invention [0004] An embodiment of the present invention provid...
