As shown in Fig. 3,4 and 5, it is all that first of annular filters wall 5, second filtration wall 6 and exterior wall 7 that described filtering ponds 4 comprise, and described first filtration wall 5, second filtration wall 6 and exterior wall 7 are in distributing with one heart and having gap each other; The delivery port of described sewage pipe 2 is positioned at the first filtration wall 5, and exterior wall 7 is connected with outlet pipe 13, and described second filters wall 6 filters wall 5 lower than first; First region, first of filtering in wall 5 is filtered the region of filtering between wall 6 with exterior wall 7 in wall 5 and second region and second of filtering between wall 6 and is all communicated with a blow-off pipe 8; Wherein first its bottom surface, region of filtering in wall 5 is tapered bucket-shaped, and above this bottom surface, be provided with the disk 9 being covered with through hole, and described disk 9 bottom is provided with leg 10; Described outlet pipe 13 communicates with described sewage pool.Wherein: wherein the first filtration wall 5, second filters wall 6 and adopts prior art, the filtration wall construction namely in Chinese patent ZL 201320001952.6; Wall 6 can be filtered in other first hole of filtering on wall 5 than second larger, and the particle crossing filter sand slightly, can carry out twice in an orderly manner and filter like this.A kind of filtering ponds 4 like this, can filter fully the sewage of discharging in leg Shrimp Litopenaeus vannamei Culture Raceway-type Ponds and precipitate, and the sediments such as effective filtering shrimp excrement, food-residue, are convenient to be for further processing; Because second filters wall 6 lower than the first filtration wall 5, the sewage leached by the first filtration wall 5 can not reflux, in addition, its bottom surface, region in the first filtration wall 5 is tapered bucket-shaped, and above this bottom surface, be provided with the disk 9 being covered with through hole, disk 9 and bottom surface have gap, such sediment enters bottom surface by disk 9, not easily kick up under the barrier effect of disk 9, reduce the burden of filtering wall, and bottom surface is tapered bucket-shaped, precipitation of being more convenient for is discharged from blow-off pipe 8, and it is higher to filter and arrange sedimentary efficiency.
It should be noted that: the filtering ponds 4 adopted in the present embodiment also overallly can adopt prior art, namely adopt the scheme shown in Chinese patent ZL 201320001952.6.
The step carrying out processing for sewage pool can select the mode of traditional input disinfectant powder, also can adopt the processing mode that our company is special, and namely sewage pool carries out process and comprises following measure:
Screen cloth is set in sewage pool water inlet and carries out physical filtering;
Carry out biological cleaning, indigenous microorganism and complex microorganism preparations is dropped in sewage purifier, by the multiple-microorganism in indigenous microorganism and complex microorganism preparations, the organic matter in sewage pool or other pollutant are decomposed, to discharge the nutritive salt containing nitrogen, P elements;
Carry out plant purification, on the water surface for the treatment of tank or in water, plant dish, flowers, fruit, algae, the nutritive salt that plant absorption is decomposed by indigenous microorganism and complex microorganism preparations, manufacture organic matter, and releasing oxygen;
Carry out animal reparation, in treatment tank, throw in the animal of Absorbable rod organic matter and edible planktonic algae plant.
Sewage pool water inlet arranges the screen cloth in every foot of 60 holes, and after being filtered further by screen cloth, by water body contaminant filter, carry out preliminary overcurrent purification, the subparticle impurity in sewage pool in water body can sink at the bottom of pond.
User can drop into appropriate microorganism in treatment tank, and under the condition of aerobic or anaerobic, organic matter or other pollutant carry out decomposing and the nutritive salt of liberating nitrogen, phosphorus etc. by microorganism.Wherein, the topmost microorganism at present for repairing aquaculture wastewater has indigenous microorganism and complex microorganism preparations.Described indigenous microorganism refers to gathers materials on the spot, many strains photosynthetic bacteria is isolated from culturing pool, through being separated, screening, the excellent species that last seed selection is easily cultivated, concentration is high, indigenous microorganism after screening, cultivation is dropped in treatment tank, through after a while, the COD (chemical oxygen demand) that can be found in sewage pool by detector has significant reduction after executing bacterium, average decline 1.3mg/L, ammonia nitrogen reduces 0.1-0.7mg/L after executing bacterium, substrate sulphide obviously reduces after executing bacterium, and substrate total organic matter also obviously reduces.Be separated from the substrate of shrimp pond, filter out nearly 10 strain shrimp pond organic matter degradation bacterias.Result shows, at short notice, and degradable shrimp pond bottom organics more than 80%.These bacterial strains do not have pathogenic effects to cultured prawn, and wherein 6 strains can improve the survival rate of young shrimp, demonstrate good application prospect.
And described complex microorganism preparations is made up of multiple beneficial bacterium, utilize the synergy of various microorganism, it can decompose various pollutant more fast, all sidedly, the excessive breeding of harmful algae in more effective suppression breeding water body, also stronger to the adaptability of environment.Calendar year 2001, the special Tiny ecosystem active bacteria formulation of Qingdao Ji Jia research unit cooperative research and development a kind of aquatic products of success, its main component is made up of useful viable bacterias of multiple compound such as bacillus, hay bacillus, Rhodopseudomonas palustris, sulfide-oxidizing enzyme and nitrifiers, can debirs effectively at the bottom of decomposition water neutralization pond, reduce ammonia nitrogen, nitroso nitrogen, hydrogen sulphide etc.Be applicable to various light and mariculture, safe to aquatic animal, nontoxic, aquatic products quality is had no adverse effects, obtains great economic benefit.
No matter be indigenous microorganism or complex microorganism preparations, if directly used, this microbial cell is very easily washed away by current, availability is low, and easily cause secondary pollution etc. due to bringing into of medium, in cultivating pool, the organic pollutant overwhelming majority is deposited on bottom, therefore needs to utilize suitable fixation support, the water body making functional bacteria pass culturing pool to arrive at the bottom of pond and growth and breeding, reaches the object of organic pollutant at the bottom of degraded pond.As this case preferred version described in indigenous microorganism or complex microorganism preparations be immobilized indigenous microorganism or complex microorganism preparations.Wherein, at present mainly using zeolite as fixation support, by the immobilized microorganism of zeolite to the degradation effect of bait leachate apparently higher than on-fixed bacterium; And the survival condition of the immobilized bacterium of vacuum storage is obviously better than the aerial immobilized bacterium of preservation.With sodium alginate, nitrifier and denitrifying bacterium are combined embedding, the aerobic zone utilizing diffusional resistance to be formed at the oxygen concentration gradient that granule interior produces, anoxic zone and anaerobic zone, nitrification and denitrification two processes are organically combined, form single-stage biological nitrogen removal system, carry out the research of nitrification and denitrification under aerobic condition simultaneously, the ammonia nitriding speed of associating fixed system is about 1.4 times when nitrifier is fixed separately, and denitrification rates is that the hybrid system of fixing formation respectively obtains 2.6 times.With calcium alginate, fixed pellet algae, bacterium and bacterium algae are for the process of aquaculture wastewater respectively, and the removal effect of Immobilized hyphae to nitrogen phosphorus is better than immobilization bacterium and immobilized algae, and the removal effect of bacterium algae immobilization glueballs to nitrogen and phosphorus is best.
Although, the superfluous organic matter be deposited in treatment tank or other pollutant can carry out decomposing and the nutritive salt of liberating nitrogen, phosphorus etc. by microorganism, but itself and unrealized its enters recycling in the ecosystem, and this water quality can not be absorbed for the animal cultivated, therefore, the absorption of Plant To Nutrient salt, the release of oxygen can be utilized, remove water nutrition by plant, ensure that the nutritive salt be removed can not cause secondary pollution, and reenter people's circulation.Heavy water vascular plant is planted artificially, as eel grass, hydrilla verticillata, model grass etc. in breeding water body or on the water surface; The aquatic vegetables such as water chestnut, lotus rhizome, wild rice stem, Gorgon fruit, arrowhead are planted in stream, pond; In sea pond, bay, cultivate tangleweed, as sea-tangle, river hedge, Bangiales etc., manufacture organic matter by materials such as N, the P in plant absorption water, and photosynthesis releasing oxygen and other material, improve water quality condition.And the plant be planted on the treatment tank water surface, at absorption water Middle nutrition, mineral salt are converted into organic matter by its root system and enter ecological circulation, purify breeding water body, meanwhile also can improve aquatic products and vegetables Isoquant, form the benign cycle of microhabitat, pollution is dropped to minimum level.
In order to ensure the effects of purification quality for the treatment of tank, when having sufficient oxygen after the water quality degraded in treatment tank, user also can put the animal can repairing water quality in a suitable place to breed in treatment tank, by relying on animal to organic absorption and the effect of ingesting to planktonic algae, reach the object of repairing environment.Wherein, as preferably, high density puts the waters Eutrophic Extent of river crab in a suitable place to breed clearly, can throw in enough Filter feeding bivalves, some echinoderm and from that grade down can remove nutriment in breeding wastewater.In addition, throw and support flea class, water flea for food, effectively can remove algae with algae and organic detritus.The bait that water flea can be used as again the aquatic animals such as fish is consumed; Cultivation river snail, freshwater mussel, in order to cut down organic matter in bed mud and nutritive salt.Throw in and consider feeding fish, as bighead, flower silver carp etc., effectively can control the excessive multiplication of algae.
The present invention is in breeding water body processing procedure, by screen cloth by the contaminant filter in culturing pool sewage, and have employed indigenous microorganism and complex microorganism to decompose organic matter in breeding water body and by ammonia nitrogen degradation, be oxidized to the nitrate that toxicity is relatively low, breeding water body is made to obtain purification to a certain extent, simultaneously on the treatment tank water surface or in water, plantation dish, flowers, fruit, algae, the nitrogen in water body is absorbed by the photosynthesis of algae, the nutriments such as phosphorus synthesize self organic matter, nitrogen in effective reduction breeding water body, phosphorus content, solve traditional precipitation and filter the suspension can only removed in water body, the problem of the dissolubility pollutant in water body can not be removed, the dish of plantation eventually simultaneously, flowers, mineral salt can be converted to organic matter and again enter biological cycle by fruit, meanwhile, when having sufficient oxygen after the water quality degraded in treatment tank, user also can put the animal can repairing water quality in a suitable place to breed in treatment tank, by relying on animal to organic absorption and the effect of ingesting to planktonic algae, reaches the object of repairing environment.
The present invention is compared with traditional waste water treatment, its cost is low, short, purification consuming time thoroughly, not easily produces secondary pollution, does not endanger breeding function, do not destroy the ecological balance, fine cycle model can be formed, not only green non-pollution, and recycling of aquaculture wastewater can be showed by real aquatic products, thus ensure the development that aquaculture is continual and steady.
