Description
Technical field:
The present invention relates to a kind of aquaculture wastewater biofilter.
Background technology:
Aquaculture wastewater has been widespread pollution from the overuse of fertilizers and pesticides in rural area primary pollution source, and especially aquaculture wastewater amount is big, concentration is high, environmental protection treatment
Difficulty is big, constantly causes contamination accident.To the processing procedure of aquaculture wastewater has a critically important process step, it is simply that remove
A large amount of solid suspensions in aquaculture wastewater.The filter plant removing solid suspension at present needs pressurization to ensure normal mistake
Filter, and easily block, needing backwash, the mud leached is not easy to be dried, and device for dehydrating sladge waste to be used is dehydrated
Could be by mud Collection utilization, use cost is high.
Summary of the invention:
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of aquaculture wastewater biofilter, and its structure design is closed
Reason, the clearance of solid suspension is high, it is not necessary to pressurizes, need not backwash, will not block, the mud natural air drying leached,
Need not device for dehydrating sladge waste, use cost is low, solves problems of the prior art.
The present invention solves that above-mentioned technical problem be the technical scheme is that
A kind of aquaculture wastewater biofilter, including cell body, is provided with the drain pipe that coiling is arranged, in draining in the bottom of cell body
Pipe is provided with infiltration aperture, and drain pipe is connected with the outlet pipe being located at outside cell body by pipeline, is coated with above drain pipe
Graded sand filtering layer, at graded sand filtering layer overlaid with permeable filter block layer, is arranged over several filter pipes at permeable filter block layer,
Described filter pipe includes the collector pipe being vertically arranged, and is provided with infiltration aperture on collector pipe, is wrapped with Buddhist nun's floss net at collector pipe
Cloth, the lower end of collector pipe is connected with drain pipe through permeable filter block, is arranged with stainless steel filtering net frame, rustless steel outside collector pipe
The lower end of screen holder sequentially passes through permeable filter block and graded sand filtering layer is fixed on bottom cell body, at stainless steel filtering net frame and collector pipe
Between be filled with filtrate, be arranged over water inlet pipe at cell body, water inlet pipe is connected with the bilge discharge pipe being located at outside cell body.
Described permeable filter block layer includes several permeable filter blocks being spliced into, and is provided with preformed hole, in advance on permeable filter block
Elastic filter material it is filled with in boxing out.
The bottom of collector pipe is connected with an interface of a three-way connector, other two interfaces by conduit coupling with
Drain pipe is connected.
It is axially arranged with an annular boss along cell body at the edge of permeable filter block layer.
The present invention uses said structure, greatly reduces the solid suspension content in sewage, reduces at follow-up sewage
The difficulty of reason, the process up to standard for aquaculture wastewater provides technical guarantee, and the present invention is not merely for aquaculture wastewater, as long as having solid
The sewage of body float is all suitable for, the mud natural air drying leached, it is not necessary to device for dehydrating sladge waste, and it instead of existing filtration
Equipment and device for dehydrating sladge waste；Use collector pipe to carry out filter sewage, improve filter effect and efficiency, decrease the use of filtrate
Measuring and decrease the frequency changing filtrate, permeable filter block can be the most precast spliced, easy installation and removal, convex annular
The setting of platform avoids mud to be deposited in cell body sidewall root and be not easy to be dried, and affects the volume drying progress of mud.

Detailed description of the invention:
For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combine its accompanying drawing, to this
Bright it is described in detail.
As Figure 1-4, a kind of aquaculture wastewater biofilter, including cell body 1, it is provided with coiling in the bottom of cell body 1 and arranges
Drain pipe 2, drain pipe 2 is provided with infiltration aperture, drain pipe 2 is by pipeline and outlet pipe 3 phase being located at outside cell body 1
Even, above drain pipe 2, graded sand filtering layer 4 it is coated with, at graded sand filtering layer 4 overlaid with permeable filter block layer 5, in permeable filter
Brick layer 5 is arranged over several filter pipes 6, and described filter pipe 6 includes the collector pipe 7 being vertically arranged, and is provided with and oozes on collector pipe 7
Water aperture, is wrapped with Buddhist nun's floss screen cloth 9 at collector pipe 7, and the lower end of collector pipe 7 is connected through permeable filter block 5 with drain pipe 2,
Being arranged with stainless steel filtering net frame 7 outside collector pipe 2, the lower end of stainless steel filtering net frame 7 sequentially passes through permeable filter block 13 and graded sand
Filtering layer 14 is fixed on bottom cell body 1, is filled with filtrate 10 between stainless steel filtering net frame 9 and collector pipe 7, sets above cell body 1
Water inlet pipe 11, water inlet pipe 11 is had to be connected with the bilge discharge pipe 12 being located at outside cell body 1.
Described permeable filter block layer 5 includes several permeable filter blocks 13 being spliced into, and is provided with preformed hole on permeable filter block 13
14, in preformed hole 14, it is filled with elastic filter material 15.Permeable filter block 13 can be the most precast spliced, installing/dismounting side
Just, elastic filter material 15 can take out in use for some time, because using elastic filter material 15 can ensure that preformed hole 14 is tight by filtrate
Close filling, and ensure filter effect.
The bottom of collector pipe 7 is connected with an interface of a three-way connector 16, and other two interfaces are connected by pipeline
Part 17 is connected with drain pipe 2.On the one hand quickly connection it is to ensure that, separately by three-way connector 16 and arranging of conduit coupling 17
Partly in order to ensure the sealing connected.
It is circumferentially with an annular boss 18 along cell body 1 at the edge of permeable filter block layer 5.The setting of annular boss 18 is avoided
Mud is deposited in cell body 1 sidewall root and is not easy to be dried, and affects the volume drying progress of mud.
Aquaculture wastewater after plant discharges, enters cell body 1 through water inlet pipe 11 by bilge discharge pipe 12, enters cell body
A sewage part in 1 enters graded sand filtering layer 4 secondary filter after permeable filter block 13 filters out solid suspension, then passes through
Infiltration aperture enters drain pipe 2 and is expelled to outlet pipe 3, and the sewage feeding next stage sewage technique after outlet pipe 3 will filter is carried out
Draining reason at next stage.Another part sewage filtrate 10 in stainless steel filtering net frame and the Buddhist nun's floss being wrapped in outside collector pipe 7
After screen cloth 8 filters, entering collector pipe 7 by infiltration aperture, the water in collector pipe 7 converges to drain pipe 2, then drains into outlet pipe
In 3.The setting of filter pipe 6 increases the contact area of sewage and filtrate, improves filter effect and efficiency, decreases filtrate
Consumption and decrease change filtrate frequency.The mud leached, because the permeable cause of permeable filter block layer, is easily dried, natural
Clear up again after Gan, it is not necessary to device for dehydrating sladge waste.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
The present invention does not describes part in detail, is the known technology of those skilled in the art of the present technique.
