Description
Technical field
The utility model belongs to technical field of aquaculture, particularly a kind of pond bottom equipment for increasing oxygen content of water.
Background technology
China's inland waters gross area 1,747 ten thousand hectares, can water surface for aquaculture 6,750,000 hectares, has utilized 5,660,000 hectares; More than 1.8 ten thousand kilometer, China coastline, for 15 meters of water depth line shallow seas of cultivation and Tideland resources area 1,330 ten thousand hectares, can cultivate 132.3 ten thousand hectares.At present, the main breeding way of China has: freshwater cultivation, fresh water cultivating large area, fish-farming in shallow marine water, Marine shoal cultivation and industrial aquaculture.Existing breeding way major part is still in original extensive cultivation pattern, and output is very low.China is an aquatic products demand and big export country, wants to obtain high yield, stable yields under culture resources at limited, must to intensive culture Mode change.
Waters, the living environment of aquiculture animal, each aquiculture animal all needs the water quality environment of its existence applicable, if water quality environment can meet the demands, aquiculture animal is energy Growth and reproduction just, and pollute if water quality environment is subject to certain, some water quality index exceeds the adaptation of aquiculture animal and restrains oneself scope, the lighter's aquiculture animal can not normal growth, and severe one may cause the large quantities of death of aquiculture animal.And fishing pool aerator, feeder improve the cultivation equipment that water quality environment ensures high yield, stable yields indispensability.Use the dissolved oxygen amount in fishing pool oxygenation function increase water, purify water, prevent fish because of anoxic floating head, death, it can effectively improve Fish Survival condition, improves cultivation density, accelerates fish growth.
Aerator increases the effective ways of dissolved oxygen content, except increasing oxygen, also can promote the circulation of water, and can the temperature stratification of anti-water-stop body, chemical stratification and oxygen stratification.If aerator, in the running of depths, pool, can improve the soil property bottom pool, make underearth oxygenation, and avoid producing toxic gas, prevent the ill death of aquatic livestock.
Aerator is by the power source such as electromotor or diesel engine driving work, " oxygen " in air is transferred to rapidly in breeding water body, comprehensive utilization physics, chemistry and the function such as biological, solve the problem of the fish floating head produced because of anoxic in pond culture, eliminate pernicious gas, promote water body convective exchange, improve condition of water quality, reduce feed coefficient, improve fishpond activity and primary productivity, increase breeding density, increase the intensity of feeding of cultivation object, realize cultivation and increase income.
On market, traditional aerator has following several: one is paddle aerator, there is oxygenation, stir the comprehensive utilization such as water, aeration, adopt maximum aerators at present, its oxygen transfer rate, dynamic efficiency are all better than other type, but running noise is large, can damage fish body, be generally used for the large-area pond culture of the depth of water more than 1 meter; Two is waterwheel aerators, has the effect of good oxygenation and promotion water body flow, is applicable to the pond that mud is darker; Three is water-spraying oxygen-increasing machines, has good oxygen-supplying function, can improve rapidly the dissolved oxygen amount of surface water at short notice, also has artistic appreciating effect simultaneously, is applicable to gardens or tourist district's crawl use.
The oxygenation effect of traditional water surface mechanical enhancement only have an appointment 50 centimetres dark, bottom water all the time dissolved oxygen is few, be unfavorable for the oxidation Decomposition of the harmful substance such as the organic matter that water bottom deposits and nitrite, cause bottom Shuifu County to collect the harmful substances such as sulphide, nitrite, ammonia nitrogen.For this reason, water-bed aeration oxygen replenishing technology is just being vigorously advocated and promoted to China's marine industry, to realize water-bed effectively oxygenation, but the energy consumption needed for aeration oxygen replenishing is high, air ducks in drink and vertically to rise because of buoyancy fast, and the dissolved oxygen time is short, and water body flow is few, therefore effectively the water body scope of aeration oxygen replenishing is few, thus causes the promotion effect of this technology unsatisfactory.In addition, in prior art, also have special water-bed oxygen-increasing device, but this apparatus structure is complicated, and is expensively not suitable for small-scale aquaculture.
