Abstract

The invention discloses an automatic sewage discharge device for cyclic flowing water aquaculture in a pond. The automatic sewage discharge device comprises a sewage collection area; a desilting water pump is mounted above the sewage collection area; proximity switches are mounted on two side walls of the sewage collection area respectively; a water inlet pipe of the desilting water pump is freely movably inserted in the sewage collection area; a water outlet pipe of the desilting water pump is inserted into a sedimentation tank on one side of the sewage collection area, and the sedimentation tank is connected with a coarse sand filter tank through a through hole in the upper portion of a partition wall of the sedimentation tank; the coarse sand filter tank is connected with a fine sand filter tank through a through hole in the upper portion of a partition wall of the coarse sand filter tank; the fine sand filter tank is connected with a nitrifying tank through a through hole in the upper portion of a partition wall of the fine sand filter tank; the nitrifying tank is connected with the external pond through a through hole in the upper portion of a partition wall of the nitrifying tank. The automatic sewage discharge device is suitable for multi-variety multi-specification aquaculture, balanced marketing can be realized, capital turnover speed is increased, and production cost can be reduced by 35%; 75% of fish metabolites and residual feeds can be collected effectively, and intrinsic virtuous cycle of the pond is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to an automatic sewage discharge device for circulating water farming in a pond. Background technique [0002] As the world population continues to increase, water resources will soon become a limiting factor for many industries, the nutritional cost of food production will further increase, the demand for high-quality aquatic products in Southeast Asian countries will increase significantly, and the fishing industry will maintain the status quo Or a downward trend, farmed aquatic products will occupy the main market. At the same time, the cost of water for agriculture, especially aquaculture, increases and the pressure on the environment increases. [0003] The biggest challenge of agricultural production in the 21st century is to use less resources to produce 3 times more products. The World Bank's Global Fisheries Program - 2030 Fisheries Project initially prop...
