Water and sewage drainage facility for industrial recirculating aquaculture system

Abstract

The invention relates to a water and sewage drainage facility for an industrial recirculating aquaculture system, which is suitable for respectively draining the circulating water and sewage containing large particles such as residual lure, feces and the like in a closed recirculating water system which is used for culturing fish and shrimps. A central culture pond water drainage pipe of the facility is arranged in the center of the culture pond; sewage drainage holes are arranged at the bottom of the center of the culture pond; the central culture pond water drainage pipe is fixed above the sewage drainage holes, and the pipe wall of the water drainage pipe is provided with small drainage holes; the upper end of the central culture pond water drainage pipe is connected with a filter cap, and the lower end thereof is a spigot-and-socket joint pipe that extends into a sewage drainage groove; the culture water flows into a water treatment pipe network outside the pond through the water drainage pipe; a sewage drainage clearance control panel is installed at the bottom of the central culture pond water drainage pipe, and the clearance between the panel and the bottom of the pond can be adjusted by rotating the sewage drainage clearance control panel; the sewage at the bottom of the culture pond flows into the sewage drainage groove through a clearance between the sewage drainage clearance control panel and the pond bottom and then flows out of the system. The facility has the characteristics of no energy consumption, automatic drainage of culture water, independent water and sewage drainage, practicality, convenience and the like.

Description

technical field [0001] The invention relates to a drainage and sewage device of an industrialized circulating aquaculture system, which is suitable for culturing fish and shrimp in a closed circulating water system to discharge circulating water and sewage (residual bait, feces, etc.) containing large particles respectively. Background technique [0002] Aquaculture is an important part of agricultural production, plays an important role in the national economy, and has developed rapidly in the past fifty years. However, with the continuous expansion of the breeding scale, the accompanying problems such as frequent occurrence of diseases and low product quality have become increasingly prominent, and this traditional breeding method will cause great damage and waste to the environment and water resources. Coupled with the limitations of technology and resources, its development has been greatly restricted. In this context, a new breeding model - high-density industrial reci...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a drainage and sewage device for industrialized circulating aquaculture system, which has no energy consumption, less floor space, convenient operation and management, and can simultaneously realize the production of water for aquaculture. Stable discharge, an integrated device for effective discharge of pollutants such as residual bait feces and excrement of farmed animals, which solves the extremely inconvenient operation of the devices in the prior art, which may discharge the farmed organisms along with the pollutants; and the concentration of suspended matter is very high Low circulating water and sewage with high concentration of large particles of dirt (residual bait, feces) enter the aquaculture water treatment system at the same time, increasing the processing load of the system and other problems
