Factory-like high-density aquaculture system

Abstract

The invention discloses a factory-like high-density aquaculture system. The factory-like high-density aquaculture system comprises a culture pond water returning mechanism, a water treatment system and two or more culture ponds. The water treatment system performs water purification treatment on sewage from the culture ponds. The culture pond water returning mechanism is communicated with a microfiltration unit of the water treatment system through a pipeline, and return water discharged from the culture pond water returning mechanism is delivered to the water treatment system. The culture ponds are communicated with a sewage treatment zone solid-liquid separation device of the water treatment system through bottom sewage drain pipelines, and delivers the sewage discharged from the bottomsewage drain pipelines of the culture ponds to the water treatment system. The factory-like high-density aquaculture system has the advantages that the load of the water treatment system is reduced, and the working efficiency of the water treatment system is improved; water is purified efficiently at a low cost, and the factory-like high-density aquaculture system is suitable for factory-like high-density aquaculture.

Description

technical field [0001] The invention relates to intelligent aquaculture technology, in particular to a factory high-density aquaculture system. Background technique [0002] my country's agriculture is composed of agriculture, forestry, animal husbandry, sideline, and fishery. According to this ranking, fishery originally ranked last, but with the continuous development of fishery in recent years, the proportion of fishery in agriculture has risen to about 10%, only Second to forestry, the domestic demand for fish and other aquatic products continues to rise. Fish is the best choice for humans to supplement animal protein, and its digestion and absorption rate is extremely high. At the same time, the cholesterol content in fish is very low, which is more beneficial to your health than other meats. However, my country's fishing volume is decreasing year by year. How to meet the rising demand of the market? The great development of the aquaculture industry is the main way to ...

Problems solved by technology

But its disadvantage is that the return water with residual bait and feces directly enters the water treatment system, which greatly increases the load of the water treatment system, and the actual water treatment efficiency of the water treatment system is low.
