Description

A water pushing aeration device for circulating water culture in a pond

technical field

The invention belongs to the technical field of fish farming, and in particular relates to a water pushing and aeration device for circulating water farming in a pond.

Background technique

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.

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 proposes that the world's aquaculture production must increase by 100% in the next 10-15 years to meet people's growing demand for aquatic products.

For water, the efficiency of all agricultural production systems must be reassessed, with trade-offs between resource allocation and reuse. Producers need to innovate to increase production efficiency, not increase production volume; set clear targets related to yield and profitability, and adopt standards that use less water resources where possible; develop technologies to improve water quality standards; determine the true cost of water use.

For soil resources, a detailed protection plan must be developed, especially for agricultural and forestry soils; strict soil protection plans must be implemented in order to feed generations; organize and encourage local farmers' cooperatives to develop soil protection plans and strengthen implementation strategies; formulate according to different goals and incentivize soil conservation programs.

For nutrients in water (often considered waste in the past), re-understand the value of these nutrients in water and its impact on people's lives, communities and regions.

As for energy, energy is limited and its price keeps rising. How can energy consumption per unit of fish produced be reduced? All agricultural and aquaculture industries must reconsider energy saving and consumption reduction measures.

What will be the cost to your community or region if you do not implement a water, soil, energy and water nutrient conservation plan?

In summary, existing technologies do not enhance water, soil, energy and water nutrient management; do not generate greater efficiency and profit; do not flush fish waste downstream to collect cleared, floating and sunken solids Automatic clearing cannot be performed.

The bottom fixing system of the fish pond requires concrete slabs to build a smooth and hard bottom, and the system requires air lifting and oxygenation equipment for water exchange. The purpose of the present invention is not to produce more fish, but to produce more fish with better benefit under the premise of protecting environment, water source and saving energy.

Compared with the traditional model, the automatic sewage discharge device of the circulating water aquaculture system in the pond of the present invention is suitable for multi-species and multi-standard aquaculture, achieves a balanced market, accelerates capital turnover, and reduces production costs by 35%.
