Abstract
The utility model relates to fluidized bed biological filter equipment. An cavity of a bed body of a hollow fluidized bed is divided into two chambers by an inner cylinder, that is an inner chamber and an outer chamber; the inner chamber is penetrated and connected with a cone-shaped water distribution apparatus which is arranged on the lower part; a water outlet is arranged at the upper end of an external wall of the bed body, and both sides of the water outlet are provided with a pair of symmetrical baffle plates to form a water outlet channel which is communicated with the water outlet arranged on the external wall of the bed body. The utility model has the advantages of simple structure, reasonable design, easy processing and installation and low cost; the fluidized bed biological filter equipment aims at removing ammonia nitrogen and nitrous acid nitrogen; the fluidized bed biological filter equipment is applied to water purification and periodic duty for fish-farming, and maintains the optimum environment for fish growth. The utility model saves water by more than 90%.
Description
Technical field
The utility model relates to a kind of purifier, definite a kind of recirculating water purification device of breeding fish of saying so.
Background technology
The fluidized bed bio filter is novel, water correction plant efficiently, but majority is used for purifying domestic sewage, is used for the degraded of high-enriched organics sewage, as reducing organism in water chemical oxygen consumption (COC) and chemical oxygen consumption (COC).The produced pollution mainly is the excreta of lost dissolving of feed and cultured fishes in the aquaculture process, and this class material is soluble in water, belongs to sewage of low concentration.Existing fluidized bed bio filter also is not suitable for the needs that cycle water fish-cultivating water purifies.The source of pollutant in the fish farming system mainly is the drainage of fish and the ammonia nitrogen that degraded produced and the nitrite nitrogen of bait composition.Ammonia nitrogen and nitrite nitrogen have toxicity to fish, in the water this class material many will cause the fish morbidity, even dead.
The content of invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of processing low-concentration organic wastewater is provided, and is suitable for the efficient removal ammonia nitrogen of aquaculture and the fluidized bed bio filter device of nitrite nitrogen.
The technical solution adopted in the utility model is, cavity fluidized bed body is divided into two chambers by inner core with the bed intracoelomic cavity, inner room and mistress, the bullet water-distributing device that inner room runs through the position setting of going to the bottom from top to bottom is connected, position, bed external wall upper end is provided with delivery port, be provided with symmetrical baffle plate in the delivery port both sides, constitute exhalant canal and be connected with the delivery port that the external wall of bed top is provided with.
The utility model has the advantages that: simple in structure, reasonable in design, easily processing, install, with low cost, remove ammonia nitrogen and nitrite nitrogen targetedly, be more suitable in breeding fish water purification and recycle the suitable environment of maintenance fish growth.This device can be economized on water more than 90%.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1～2 as can be known, the utility model is a kind of fluidized bed bio filter device, it is characterized in that: cavity fluidized bed body 1 is divided into two chambers by inner core 2 with bed body 1 inner chamber, inner room 3 and mistress 4, the bullet water-distributing device 5 that inner room 3 runs through the position setting of going to the bottom from top to bottom is connected, position, bed body 1 outer wall upper end is provided with delivery port 6, is provided with symmetrical baffle plate 7 in delivery port 6 both sides, constitutes exhalant canal 8 and is connected with the delivery port 6 that bed body 1 outer wall top is provided with.
Described inner room 3 or mistress 4 are evenly equipped with and filter bead 9.
Described bead 9 is polyetylene beads, polyphenyl bead, resin beads.
Described bed body 1 links to each other with the demoulding device of outer setting by pipeline.
Ore deposit rock sand grain filtering material 10 is equipped with at described inner room 3 middle parts.
Water-distributing device in the bed body described in the utility model has adopted the bullet water-distributing device, enters the water in the body, pours bullet water-distributing device bottom earlier.By reaction force, water is equipped with ore deposit rock filtrate from the bottom of bed body through the inner room middle part, filters the back and rises, and rises to the top of a body, flows into the external chamber of bed, constitutes exhalant canal by plate washer, is discharged by delivery port.Big and the fluidisation of the ore deposit rock sand grain surface area that the inner room middle part is equipped with, the biomass of particle-bound bacteria etc. is big, and the microbial reaction environmental condition is good.Microorganism absorbs, decomposes and utilize material such as nitrogenous class in the water in process of growth.Can change into nitrite nitrogen to ammonia nitrogen fast attached to the biomembrane on the carrier in the bed body, the water that contains nitrite nitrogen enters outer indoor, by nitrifier nitrite nitrogen is further changed into nitrate, after water after the purification overflows from delivery port through rising once more behind the baffle plate, support fish to use again.This fluidized bed bio filter has designed the flow guide system that divides cell structure and science in the bed body, help the carrying out of microorganism ammoniation and nitrification more, removes ammonia nitrogen and nitrite nitrogen efficiently.
