Description
Technical field
The present invention relates to a kind of aquaculture pond bottom water treatment systems, are a kind of oxidation ditch type micro-holes specifically
It is aerated aquaculture pond bottom water treatment system and construction method, belongs to treatment technology of effluent from aquaculture field.
Background technology
The dissolved oxygen content that breeding water body is improved by oxygen increasing equipment, be in pond culture generally by the way of.At present
Pond waters oxygen increasing equipment mainly has paddle aerator, waterwheel aerator and micro-pore aeration formula aerator etc., the above equipment
Since structure is different from principle, there is also differences for the scope of application and oxygenation effect to pond；But exist to more than 1.5m water
The undesirable problem of the oxygenation effect of bottom oxygen content close to the 0mg/L water bodys in deep pond.
The free sedimentations such as pond culture Mesichthyes excreta and excrement residual bait cause breeding environment to deteriorate, deposition in bottom of pond
Seriously polluted problem：The water depth of existing aquaculture pond is in 1.5m~2.0m or so, the increasing that generally uses at present
Oxygen mode is that the oxygen increasing equipments such as oxygen increasing equipment paddle aerator, waterwheel aerator and aeration-type oxygen-increasing machine are placed in pond water
Face is distributed in pond bottom；Paddle aerator category local oxygen enriching is only capable of having promotion molten in a certain range of water body in equipment periphery
The function of oxygen content；Waterwheel aerator category water body upper layer oxygenation, does not have oxygenation effect to 1m or less water bodys；Aeration-type oxygen-increasing machine
Belong to bottom oxygenation, but the reason of by aerating pipelines arrangement, the water body on only aerating pipelines periphery is effective, to bottom water body
Oxygenation effect also unobvious.Pond application test the result shows that, above increasing of several oxygenation ways to pond bottom water body at present
Oxygen effect is undesirable.
In addition, according to needing additionally to be arranged to realize the exchange of water body up and down for aquaculture pond in the prior art
Water body switching equipment can not reach this function by aeration oxygen replenishing.
Micropore aeration aerator is that one kind is set compared with paddle aerator and the stronger oxygenation of waterwheel aerator oxygen transfer rate
It is standby.Micro-pore aeration oxygenation way has many research in the field of municipal sewage treatment of environmental protection, but also difficult in aquaculture field
To realize, how adaptability design is carried out to micropore aeration aerator, so that it is played a role in aquaculture pond field, be this
Field technical barrier urgently to be resolved hurrily.
Invention content
The object of the present invention is to provide a kind of oxidation ditch type micro-hole aeration aquaculture pond bottom water treatment system and works
Skill is substantially improved the effect and uniformity of the full water body aeration oxygen replenishing of cultivating pool, while realizing the exchange of water body up and down.
The present invention takes following technical scheme：
A kind of oxidation ditch type micro-hole is aerated aquaculture pond bottom water treatment system, including axial-flow pump 1, suction line 8,
Absorb water manifold 7, leading portion inlet channel 2, filler lautertuns 3, stage casing oxidation ditch 9, back segment drainage ditch 12；If being arranged on suction line 8
Dry suction hole, multiple suction lines 8 are arranged at intervals on the position close to pond bottom, and are connected to water suction manifold 7, axial-flow pump
On water suction manifold 7, pond side is stretched out in the end of water suction manifold 7, and is connected to inlet channel 2, the end of inlet channel 2 for 1 setting
It is connected to the top of the side of filler lautertuns 3, the bottom of 3 other side of filler lautertuns is equipped with the first crest of weir 6, first weir

Pipe range is the width of pond bottom, the hole that 4 apertures are 15mm~20mm is opened up along tube wall perimeter decile, along pipe range per 100mm
One group of trepanning, suction line 8 arrange one per 3m~5m.
Further, axial-flow pump 1, flow is pond waters total amount 1/10th per hour, and lift is 1.5 m~2m, axis
Stream pump discharge is connect with leading portion inlet channel 2.
Further, oxidation trench depth in stage casing is 2.5m~3m, and width and length meet the water body into irrigation canals and ditches in irrigation canals and ditches
The middle requirement for stopping 8min~10mim；Aeration tube 11 is evenly arranged in the bottom of stage casing oxidation ditch, total amount be every square metre of 1m~
2m；The air quantity of roots blower 10 is according to every meter of aeration tube 2m per hour3。
Further, the entrance of back segment drainage ditch 12 in oxidation ditch end close at the water surface；The length of second crest of weir 14
It is the 2/3 of the pond width.
A kind of construction method of above-mentioned oxidation ditch type micro-hole aeration aquaculture pond bottom water treatment system, around foster
One section of irrigation canals and ditches is arranged in the periphery for growing pond, and irrigation canals and ditches divide leading portion, stage casing and back segment；Leading portion bottom by multiple phases across a certain distance
The pond bottom unicom of parallel pipeline and one end induces one pond bottom water body irrigation canals and ditches；Pond bottom water body is in the end of leading portion
By entering stage casing microporous aerated oxidation ditch after filter screen and packing layer filtering；Stage casing is that microporous aeration device is laid in entire bottom
The quick aerobic oxidation ditch for having certain length, flow into oxidation ditch and pass through cycle in the end in stage casing by the water body that is quickly oxygenated
The drainage ditch of pump into back segment flows back at the top of the cultivating pool of the other end, and above procedure can make pond bottom oxygen content extremely low

Pond is sucked out in the water body of bottom oxygen content close to 0mg/L, introduces irrigation canals and ditches, is filtered by filler, removes the harmful substance in water body；
So that the hyperoxic water body in upper layer is added to bottom simultaneously, improve the oxygen content of bottom water body, improve pond bottom water quality, reduces
Disease occurs.
2) pond is sucked out by the water body by pond bottom oxygen content close to 0mg/L, introduces oxidation ditch centralized processing, improves
Treatment effeciency；Trench depth is designed as 2.5m~3m, by improving depth, increases dynamic efficiency；
3) all irrigation canals and ditches can be capped plate, and whole system takes up little area.
4) by making the water body of the saturation dissolved oxygen of inflow drainage ditch be set on inlet channel opposite from the bottom on pond one side
The crest of weir on the pond side on one side enters in pond, completes the exchange of the upper and lower layer water body in pond, pushes pond waters from one side to another
It flows on one side, improves the dissolved oxygen content of pond entirety water body.
5) a system can be established with a pond, can also multiple pond parallel connections build a system, reduce system structure
This is built up, system effectiveness is improved.
6) water treatment facilities occupied space has been saved in the space for making full use of cultivating pool periphery；
7) the extremely low bottom water body of oxygen content is concentrated oxygenation, efficiency can be greatly improved, reduce cost of water treatment；
8) this system is simple in structure, easy to operate, and the oxygen increasing equipment that can solve generally to use at present is to cultivating pool bottom
The problem of layer water oxygenation difficulty, while giving full play to the efficient feature of micro-pore aeration oxygenation.
