To reach above-mentioned technical purpose, the technical scheme is that a kind of circulating water culture system is provided, the system bag
Include a culture pond, a rotating disc type filter, a collecting-tank, a water pump, an integrated form biofilter, a ultraviolet ray disinfector,
One aerator, the delivery port of culture pond is sequentially communicated rotating disc type filter, collecting-tank, water pump, integrated form biofiltration through runner
Device, ultraviolet ray disinfector, the delivery port of ultraviolet ray disinfector are connected through runner with the water inlet of culture pond, ultraviolet ray disinfector
Interior liquid level is higher than liquid level in liquid level in culture pond, integrated form biofilter and is higher than in liquid level in ultraviolet ray disinfector, culture pond
Liquid level is higher than liquid level in liquid level in rotating disc type filter, rotating disc type filter and is higher than liquid level in collecting-tank；Integrated form biofiltration
Device include an immersion biofilter, at least one rain type biofilter and one connection immersion biofilter and
The pipeline of rain type biofilter；Immersion biofilter includes a filter tank, an aeration mechanism, a baffle assembly and all one's life
Thing filter plate, aeration mechanism is located at filter tank bottom, and baffle assembly includes at least one first dividing plate and at least one second partition, the
One dividing plate and second partition are disposed alternately in filter tank and filter tank are divided into multiple independent filtering ponds in transverse direction successively,
Overflow is formed between being formed between first dividing plate lower end and filter tank bottom at the top of communication gap, second partition upper end and filter tank
Gap, the biological filter plate for having some through holes is arranged in filter tank along the longitudinal direction perpendicular to baffle assembly；Rain type biology mistake
Filter includes filter, once filter on a casing, one, and casing is separated to form from top to bottom by upper filter and lower filter
Inhalant region, filtering area and the catchment being sequentially arranged, the upper surface of upper filter are less than the overhead height of second partition, filtering area
Interior to be filled with biologic packing material, standpipe is vertically arranged in casing, and upper end is connected with inhalant region, lower end passes through filtering area；Pipeline
Want to connect with the water inlet end of immersion biofilter afterbody filtering ponds and standpipe.
Compared with prior art, beneficial effects of the present invention include：After water outflow in culture pond, in the biological mistake of integrated form
The S-shaped flowing of sewage makes water residence time increase in filter tank in filter, adds in water and integrated form biofilter
The time of biofiltration material reaction, there is more preferable treatment effect to the ammonia nitrogen and nitrite in reduction water；By submerging
The combination of formula biofilter and multiple rain type biofilters, improves sewage quantity amount, and overall treatment efficiency is high, by
Two kinds of processing equipments are have passed through in sewage, have more preferable treatment effect to the ammonia nitrogen and nitrite in reduction water.

Liquid pours in down a chimney and influences the purity of flushing liquor, after the fan-shaped cleaning solution that protection 27,4 injector heads 275 of back purge system spray is overlapping
Any vertical section of correspondence filter screen 264 can be completely covered, a certain region will not be missed, cleannes are high, if event occurs in injector head 275
Barrier, turning nut 2755 makes injector head 275 be separated with branched pipe 274, is convenient for changing.
When integrated form biofilter 5 works, as shown in Figure 13, Figure 14, Figure 15, the water source handled through physical filtering is from entering
Water pipe 5151 flows into upper filter tank 5101, under water enters in the first filtering ponds 51a from upper filter tank 5101 through biofiltration plate 517
Filter tank 5102, it is same filtering pool inner water can be flowed freely between upper filter tank 5101 and lower filter tank 5102, while water from first every
The bottom of plate 5181 flows into the second filtering ponds 51b, is constantly flowed into from water inlet pipe 5151 with dampening, when liquid level in the second filtering ponds 51b
During higher than second partition 5182, water flows into next filter tank from the top overflow of second partition 5182, water two dividing plates later
Along the runner channel of S-shaped through two points of filter tanks under effect, due to the processing sewage speed ratio submergence of rain type biofilter 52
Formula biofilter 51 is slow, and a part of sewage can be made to be stranded in immersion biofilter 51, a part of incompletely processed
Water flows into tank from outlet pipe 5141, and another part water flows into inhalant region 5231, casing 522 through connecting tube 53 from standpipe 521
Interior water passes sequentially through filter 5241, the filtering area 5232 for being equipped with biologic packing material, lower filter 5243 and reaches row from top to bottom
Pool 5233, water flows into next process from catchment 5233 through discharge outlet 5221；The upper level of upper filter 5241 is low
In the overhead height of second partition 5182, water is flowed into rain type biofilter 52 from immersion biofilter 51
, only need to be in gravity when water flows in immersion biofilter 51 during pool 5231, it is not necessary to which extra power is provided
It can just be completed under effect, it is not required that extra power, energy-conservation are provided；The mode of this drainage flow adds water and integrated form
The time that biofiltration material reacts in biofilter 5, ammonia-nitrogen content in water is eliminate or reduced, while being aerated mechanism
519 water supply aeratings always, increase water oxygen level, and overall treatment efficiency is high.
Beneficial effects of the present invention include：After water outflow in culture pond 1, sewage is in S in integrated form biofilter 5
The flowing of shape makes water residence time increase in filter tank, adds water and biofiltration material in integrated form biofilter 5
The catalytic time, there is more preferable treatment effect to the ammonia nitrogen and nitrite in reduction water；By immersion biofilter
51 with the combinations of multiple rain type biofilters 52, sewage quantity amount is improved, overall treatment efficiency is high, due to sewage warp
Two kinds of processing equipments have been crossed, have had more preferable treatment effect to the ammonia nitrogen and nitrite in reduction water.
The embodiment of present invention described above, is not intended to limit the scope of the present invention..Any basis
Various other corresponding changes and deformation that the technical concept of the present invention is made, should be included in the guarantor of the claims in the present invention
In the range of shield.
