Description
Technical field
This utility model relates to culturing pool bottom blowdown technical field, particularly to a kind of culturing pool bottom blowdown system.
Background technology
At present in Miniature high-density aquaculture; high progression by a large amount of generations of cultivation metabolite and deposit and water quality; again because raiser's environmental protection protective awareness is weak; breeding water and sediment of pond are arbitrarily discharged in periphery natural water area; water is drawn back in pond again before starting by cultivation; accumulating through for many years, breeding water pollutes extremely serious, such water source serious threat cultivation success rate.Therefore, need above-mentioned aquaculture water is carried out blowdown filtration, a kind of way is aquaculture water to be circulated formula filter and dirt interception, such blowdown mode needs to use large-area culturing pool, and need to use power set to make water circulation flow, just can intercept the dirt in water, cause blowdown added cost.Secondly, relatively simple method for discharging pollution is exactly arrange blowdown apparatus in the bottom of culturing pool, and these blowdown apparatus are generally the blowoff line being set at the bottom of culturing pool, is namely provided with some fixing blow-off lines bottom culturing pool.Deposition of dirt is to dropping into blow-off line time at the bottom of pond, when needing blowdown, as long as opening blow-off line, dirt will flow out culturing pool along with current, but such filth-discharging effect is also unsatisfactory, because water body can not get flowing, only the dirt near blow-off line can fall in blow-off line, and other most dirt is still deposited on from the bottom of the pond of 3-10m near blow-off pipe, still breeding water body is caused great pollution, and then affect rate of growth and the survival rate of prawn, largely effect on the benefit of breeding production.In order to remove the dirt near blow-off pipe, way currently mainly is in addition to regularly blow-off pipe blowdown, in addition it is also necessary to being manually entered at the bottom of pond and clean, contaminant removal effectiveness is low, and filth-discharging effect is undesirable.
Notification number is the bioelectric detecting cultural method of a kind of big specification prawn disclosed in the patent of invention of CN103404458A, it includes the high-order culturing pool of Criterion, the integrated treatment of source quality, the cultivation of foundation bait, the input of shrimp Seedling, the steps such as the bioelectric detecting of high-order culturing pool water quality environment and disease, the invention provides the big specification prawn culturing pattern of a kind of high-efficiency environment friendly, bioelectric detecting method in conjunction with probiotics and useful algae, the prawn specification obtained is bigger, quality better, yield is high, culture benefit is good, and the problem having stopped drug residue, a kind of new evolutionary path is provided for shrimp culture industry, there is good market development prospect.Residual bait, feces that culturing pool bottom collection is got rid of by this patent by the standard high position set up are directly used in vegetable, melon and fruit plantation, the dirt causing discharge will to environment, the another strong chlorine oil of its use, DBDMH etc. belong to chemical disinfection preparation, there is residual serious after using in breeding water body, cultivated animals and environment can be caused certain adverse effect.
Utility model content
This utility model aims to solve the problem that in existing culturing pool, sewage, dirt arbitrarily discharge, cause water body, environmental pollution serious thus affecting the problem cultivating success rate, there is provided a kind of efficiently, the bottom blowdown water system of environment-friendly type, this culturing pool bottom blowdown system can discharge the residual bait in water body, feces in time, reduce water body load, effectively reduce ammonia nitrogen and content of nitrite in water body and in environment, discharge the amount of nitrogen, phosphorus, green, environmental protection.
For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions.
Culturing pool bottom blowdown system, including sewage draining exit, sewage well, described sewage outfalls setting is in the lowest point at the bottom of the pond with 0.5%～0.7% gradient, described sewage draining exit is arranged and prevents escaping net, described sewage draining exit is connected with sewage well by blow-off pipe, to be arranged on one end of sewage well dismountable is connected to first and intubates for described blow-off pipe, described blow-off pipe is connected to the bottom of sewage well, described first upper end intubated exceeds the well head of sewage well, described culturing pool bottom blowdown system also includes shining manure pit, fish and vegetable symbiotic wetland purification system, described sewage well connects the residual bait for depositing in sewage well with shining manure pit, feces drains into solarization manure pit, described solarization manure pit is connected to supernatant drain pipe, described supernatant drain pipe and fish and vegetable symbiotic wetland purification system connectivity.
Described fish and vegetable symbiotic wetland purification system includes fish and vegetable symbiotic wetland purification pond, described fish and vegetable symbiotic wetland purification pond arranging floating bed, described floating bed be provided above drip irrigation system, described drip irrigation system connects with supernatant drain pipe.
Described supernatant drain pipe is connected to the bottom shining manure pit, is provided with removably connect with supernatant drain pipe second and intubates in solarization manure pit, and described second upper end intubated exceeds the Chi Kou shining manure pit.
Described blow-off pipe and first intubates by the first elbow connection.
Described supernatant drain pipe and second intubates by the second elbow connection.
Described first intubates top and offers overfall lower than the position of the well head of sewage well.
During soil that culturing pool bottom blowdown system of the present utility model can be used for Penaeus vannamei is pool cultivated, filth-discharging effect is good.
Beneficial effect
Culturing pool bottom blowdown system of the present utility model can discharge the residual bait in water body, feces in time, reduces water body load, effectively reduces ammonia nitrogen and content of nitrite in water body and discharges the amount of nitrogen, phosphorus in environment, green, environmental protection.The sewage draining exit being arranged on bottom culturing pool, sewage well, solarization manure pit, fish and vegetable symbiotic wetland purification system are combined, filth-discharging effect is good, muddy thing in sewage well is not the external world of directly discharge, but be transported to solarization manure pit concentration and precipitate again, supernatant after precipitation is used for watering vegetable, and dry is then used for planting vegetables.Reduce the pollution to water body.
