Embodiment Construction

[0028] like figure 1 An aquaculture facility using a circulating water body is shown, having the following ponds or tanks connected in sequence:

[0029] 1) Aquatic pond 3, where separation components, air pipe 1 and temperature regulating pipe 2 are installed. like figure 2 As shown, the separation assembly includes a fish and shrimp retaining ring 33 and a solid-liquid separation device 31 , a plurality of solid waste discharge holes 34 are distributed on the fish and shrimp retaining ring 33 , and a plurality of aqueous solution discharge holes 32 are distributed on the solid-liquid separation device 31 . The fish and shrimp retaining ring 33 is arranged on the periphery of the solid-liquid separation device 31, and the bottom of the pool between the two is connected with a solid waste discharge hole 34, which is connected to a solid waste discharge pipe 36; the solid-liquid separation device 31 is internally connected to the waste water outlet and waste water discharge ...

Abstract

The invention provides a facility using circulated water for aquaculture. The facility includes the following ponds or groove tanks which are successively connected: an aquatic pond, a nitrogen-reducing groove tank, a bacterial strain pond, and a dissolved oxygen groove tank. The aquatic pond is provided with a separation assembly and an air pipe. The separation assembly includes a fish and shrimp back-up ring and a solid-liquid separation apparatus. The bottom part of the nitrogen-reducing groove tank is provided with an ozone inlet. The bacterial strain pond is in connection to a bacterial strain adding pipeline, and a multi-fiber filter material and a porous filter material are floated in the pond. The dissolved oxygen groove tank is in connection to a venture ejector which has high oxygen concentration. The oxygen concentration input by the air pipe is around 3-9mg / L, and the dissolved oxygen concentration in the dissolved oxygen groove tank can reach 10-20mg / L. According to the invention, the facility can save large amount of water resource, increases survival rate of aquatic products, has high culture efficiency and explicit economic benefits.

Description

technical field [0001] The invention relates to the treatment and reuse technology of wastewater produced in aquaculture. Background technique [0002] In aquaculture, the problem of water quality pollution affecting the survival rate of aquatic products is prone to occur. The traditional method is to introduce fresh water to change the water or use an aerator to increase oxygen in the water body. The former has more demand and consumption of water resources, and the latter can only Oxygenation cannot fundamentally remove pollutants in water. [0003] The invention with application number 2013101071480 discloses a BRGA municipal sewage treatment method, which includes the following steps: pre-sedimentation of municipal sewage in a pre-sedimentation tank; setting a selective high-efficiency bioreactor in the front section of the gradient biochemical aeration tank to treat the sewage , and at the same time add microbial growth promoter; carry out gradient biochemical aeration...
