Description
Technical field
The present invention relates to a kind of equipment that the industrial aquaculture engineering of water treatment separates with liquid solid in the breeding wastewater that is used for, especially be applicable to the two-tube blowdown apparatus of the separating treatment of fish, shrimp batch production high-density breeding waste water suspended particulate substance.
Background technology
China is marine fishery big country, and the mariculture product population of China in 2004 reaches 1,309 ten thousand tons, accounts for more than 60% of world's mariculture product population, for the food security of China's 1,300,000,000 populations has been made contribution.But China is not marine fishery power, and this mainly shows, and the ubiquitous facility of aquaculture is outmoded, simple and crude, production technology is immature, productivity ratio is low, production stability is poor, the breeding process disease takes place frequently, the breeding production environmental pollution serious, degradation aspect under the cultured product quality.
Develop new cultural technique and aquaculture model, make breeding process more " environmental friendliness " become the key issue that mariculture industry needs to be resolved hurrily.Industrial aquaculture is generally believed it is the effective way that solves environmental pollution, improves the quality of products.Breeding enterprise also wish by the development industrial aquaculture can, to realize sustainable development, particularly can adapt to the demand of opening the markets in the whole world and further reduce production costs.The existing seawater industrial aquaculture of China is to adopt open flowing water production substantially, is in the industrial aquaculture primary stage.Be characterized in that water consumption is excessive, simple to the pre-treatment of water quality, output is difficult to improve, and most units of culturing do not establish post processing, the direct discharge into sea of breeding wastewater, the persistent survival that causes the sea area to pollute and jeopardize enterprise self.For this reason,, walk the road of closed circulation water industrial aquaculture, change present production status, thoroughly improve inharmonic relation between breeding production and the environmental protection, be only best outlet from the overall situation of protection environment and sustainable utilization resource.Industrial aquaculture utilizes mechanical filter, biofiltration to remove residual bait, ight soil and NH in the breeding water body by the technology in fields such as comprehensive integration modern biology, architecture, chemistry, electronics and engineering science
4-N, NO
2Harmful substances such as-N are again through sterilization oxygenation, removal CO
2, fail back after the temperature adjustment and culture the pond and realize the recycling of breeding water, the conserve water resource makes breeding water body continue to keep high dissolved oxygen state and stable water quality environment so greatly, significantly improves the unit of water body productivity.No matter the closed recirculating industrial aquaculture is that water consumption or floor space all will significantly be lower than pond culture and open flowing water aquaculture model, and can improve cultivation density greatly; In addition, industrial aquaculture is reduced to minimum degree to the harm of extraneous contamination source and pathogene, and production environment is stable, can produce the high-quality non-harmful product that meets international standard fully, and, reduce the pollution of breeding production to environment by recycling treatment to breeding wastewater, realize environmental friendliness.
Suspension be considered to industrial aquaculture produce in one of sixty-four dollar question, it can cause death fish, reduce growth rate, increase disease infection rate etc.Density and particle size have determined the fundamental characteristics of suspension, the total suspended matter of non-precipitation (Total suspended solids, TSS) diameter range is generally between 1～100 μ m, precipitable TSS diameter is greater than 100 μ m, even studies show that (44mg/L) also can damage the fish gill under low concentration, in addition, TSS also blocks the biofilter of the circulatory system; (Volatilesuspended solids, VSS) degraded produces NH3 and BOD, polluted water to decomposable suspension.Also do not set up before the standard mesh of relevant high-density breeding concentration of suspension, Alabster and Lloyd have no effect to fish when finding concentration of suspension less than 25mg/L by the research to aquaricullure, when being higher than this concentration, have some adverse influences.Owing to be high density and limited breeding environment, the safe concentration of FIFAC (1980) suggestion TSS should be lower than 15mg/L, and the Muir suggestion should be limited to 20～40mg/L scope.Feeding speed, fish body size and temperature are depended in the generation of suspension in the breeding production, also depend on used feed type, in addition, also be subjected in the system water body turbulent flow and again the number of suspension influence.Therefore, the characteristics of suspension are in the industrial aquaculture system: high organic, low-density, bigger size range.In these particulates, less than the fine particles of 30 μ m potential hazard maximum to fish.Suspension generation transformation rule to rainbow trout, catfish and several shellfishs has carried out some researchs, and these results of study show: 30～60% of the feed of throwing something and feeding becomes sediments, and shell-fish is less slightly; Decomposable suspension accounts for the very most of of total suspended matter, and the result of study of Wimbely is that VSS accounts for 88%, and high organic content has reduced the density contrast between TSS and the water.Precipitation and filtration are two kinds of common methods removing suspension, and treatment technology comprises: Gravity Separation (sedimentation basin, spiral vortex type separate), physical filtering (membrane filtration, granule medium filtration, porous media filtration etc.).The transmission course of particulate has several patterns such as collision (interception), precipitation and diafiltration between Blang's diffusion, particulate and medium.
