Description
Technical Field
The utility model relates to an aquaculture technical field especially relates to a circulating water penaeus vannamei farming systems based on biological wadding group water treatment technique.
Background
The biological floc refers to inorganic and organic matters mainly comprising aerobic microorganisms in the culture water, and particularly comprises bacteria, phytoplankton, algae, organic debris (residual baits and excrement) and an agglomerate formed by bioflocculation of some inorganic debris. The biological floc technology is utilized to adjust the water body nutrition structure; adding organic carbon into the water body, adjusting the carbon-nitrogen ratio in the water body, promoting the propagation of heterotrophic bacteria in the water body, decomposing inorganic nitrogen by using microorganisms, converting nitrite nitrogen and ammonia nitrogen generated by shrimp metabolism and organic matter decay in the breeding water body into self components of bacteria, and simultaneously, particles generated by bacterial flocculation can be ingested by the shrimps, thereby finally playing the roles of maintaining stable water quality, reducing bait coefficient, improving immunity of breeding organisms, reducing water change amount and increasing yield; can solve the problems of water resource shortage, environmental protection restriction, high feed cost and the like in the aquaculture industry at present.
In the implementation process of the existing biological floc technology, the biological floc and prawns are cultured in the same water body, and feeding of the prawns and addition of carbon sources and microbial agents of the biological floc are carried out in the same culture pond. When breeding the pond quantity and being more, throw the material work load huge, biological wadding group is in the process of cultivateing simultaneously, and the quality of water fluctuation is great, need take out survey quality of water often in the routine maintenance in-process, and present plant is mostly multi-pond farming systems, and the water sample test volume is huge, and in biological wadding group culture process, the misoperation causes quality of water to worsen easily, nitrite nitrogen content and ammonia nitrogen content accumulate rapidly in the water, very easily causes the shrimp stress, dies even. At the moment, a large amount of water can only be changed, the biological floccules need to be cultured again after the water is changed, a large amount of time and materials are consumed again, in a word, the biological floccules and the prawns are cultured in the same water body, the daily maintenance workload is large, the operation is complex, and the culture risk is large.
The circulating water culture mode is a representative of an industrial aquaculture technology, and is a culture mode for removing suspended particulate matters, ammonia nitrogen, nitrite nitrogen and other organic matters and inorganic matters in a water body and realizing water body purification and recycling by carrying out a series of treatment processes of physical filtration, biological filtration, sterilization, disinfection, degassing, oxygenation and the like on a culture water body. The circulating water culture realizes the water body cyclic utilization, greatly reduces the water resource consumption, also greatly reduces the culture tail water discharge amount, and solves the resource problem and the environmental protection problem which restrict the aquaculture development at present. But the recirculating aquaculture mode depends heavily on facility equipment investment and daily maintenance management. In the process of fish culture, the circulating water culture mode is widely applied, but the circulating water culture mode is just started to be applied in the industrial culture mode of the penaeus vannamei boone.
The successful implementation of the biological floccule culture mode has the technical key points that: a large amount of dissolved oxygen needs to be consumed in the implementation process, water flow needs to be stirred simultaneously, flocs are suspended in a water body all the time and cannot sink to the bottom, if the flocs sink to the bottom of the tank and the accumulation amount is increased, the biological flocs can be converted from aerobic reaction to anaerobic reaction, organic matters and inorganic matters in the flocs can decay and accelerate to cause the water body to deteriorate, and further the implementation process fails. Therefore, in the implementation process, a large amount of aeration is needed in the water body, firstly, enough oxygen is provided for the aerobic reaction in the biological flocs, and secondly, the aeration process is to stir the water flow to suspend the flocs in the water body.
Aeration is also needed in a biofilter in a traditional recirculating aquaculture system so as to provide sufficient oxygen for nitrosation and digestion of bacteria, wherein the bacteria are cultivated in a filter material or filler, and a biological film is formed on the surface of the filter material or filler to realize the function. The biological floc and the biological filter are superposed in function, and the biological floc is applied directly to the culture water body in the culture process of Penaeus vannamei, i.e. the growth of the Penaeus vannamei is in the same environment, while the biological filter in the circulating water culture system is an independent water treatment unit and is isolated from the culture object. The differences of the traditional circulating water culture system in the culture process flow caused by the differences of culture objects are applicable to fish culture but difficult to apply to prawn culture, the circulating water culture system is applied to the culture process of the penaeus vannamei boone and is combined with a biological floc culture mode at the same time, a biological filter tank is replaced by the biological floc tank, more importantly, the biological floc water treatment process is isolated from the living activity environment of the penaeus vannamei boone, and other facility designs are correspondingly modified, so that the circulating water culture mode of the penaeus vannamei boone based on the biological floc water treatment technology can be established.
