Description

Water storage tower for circulating cultivation

Technical Field

The utility model relates to an aquaculture's technical field specifically is a can be used for circulating the retaining tower of breed.

Background

With the increasing world population, water resources can quickly become a factor for limiting a plurality of industries, the nutrition cost required by food production is further increased, the demand of southeast Asia countries on high-quality water products is greatly increased, the current situation of the fishing industry is kept or the fishing industry is in a descending trend, and the cultured aquatic products occupy the main market. Meanwhile, the water cost of agriculture, especially aquaculture industry, is increased, and the environmental pressure is increased. The biggest challenge in the 21 st century agricultural production is to produce more than 3 times the product using less resources. World bank global fishery program-2030 fishery project preliminary: the world aquaculture amount must be increased by 100% in 10-15 years in future to meet the increasing demand of people on aquatic products.

Pond culture, reservoir culture and riverway cage culture are always traditional aquaculture modes in China, but the cage culture is generally suitable for wide water areas of riverway surfaces, and the yield of the pond culture per unit area is much lower than that of the cage culture. In recent years, due to the pressure of national ecological environment protection, the current river reservoir net cages completely forbid the cultivation and advocate the green, environment-friendly and intensive cultivation. Pond culture also conforms to the aquaculture mode of being the main farming, and people adopt the circulating water culture technology in the pond in order to improve the culture yield. The circulating flow water culture technology in the pond integrates the circulating flow water fish culture technology and the common pond fish culture technology, changes the open free-range culture of the traditional pond into the intensive captive culture, and realizes the running water fish culture of the 'still water' pond. Through the several (install the aeration equipment and push away water and make the flow, waste such as incomplete bait fish excrement is installed to the dirt suction equipment extraction that one end was pushed away to the breed basin of two rivers intercommunications of building on one side of the pond, form annular rivers in whole big pond, can concentrate to feed fish in "runway" basin, can utilize rivers to concentrate an inslot unified processing again with the excrement.

Researches show that the circulating water in the pond has three main disadvantages: firstly, the daily operating cost is high, the fish culture in the pond by the circulating water mainly depends on the continuous operation of high-power water pushing and oxygen increasing equipment to provide sufficient oxygen for the fish cultured in the high density in the water tank and manufacture pond annular water flow, the daily power consumption is large, and the operating cost is high; circulating water aquaculture mechanical equipment in the pond is more, and the exchange of wading of water fragile needs regular maintenance, especially need well supporting emergent power generation system and reserve oxygen equipments in order to prevent unexpected outage stall, and this has undoubtedly increased the manpower and materials cost of operation. Secondly, the sewage absorption effect of the water channel of the runway is poor, although one section of the water channel for circulating water cultivation in the pond is provided with a waste precipitation area such as residual bait fish dung and the like, and equipment is used for absorbing sewage, the residual bait fish dung in the water flows along with water body and is usually in a suspension state, the equipment can only extract a small part of sewage in the water, and if the fish body is killed, the sewage absorption pipeline of the equipment is likely to be blocked. Thirdly, the occupied water surface area is large, the area of circulating water culture in the pond is generally not more than 20 percent of the total area of the pond, the water surfaces of other ponds need to be matched with water purifying plants for planting water purification plants to treat culture water quality, otherwise, the requirement of fish culture water bodies in the pond runway cannot be met.

However, the traditional pond culture also faces the requirements of more difficult land property, strict standard discharge of tail water and the like, the culture yield promotion space is smaller, and the further development of the aquaculture industry in China is restricted to a certain extent. Therefore, it is necessary to purposefully invent a land-based aquaculture circulating culture technology and a matched device which occupy less water area, save resources, are convenient and labor-saving in compliance with the development requirements of the times, so as to make up for the shortage of aquatic product supply caused by the forbidden culture of the net cages in the water area and meet the increasing consumption requirements of green and healthy aquatic products of people.
