Description
Technical field
The present invention relates to the circulating water purification system of a kind of Cyprinus carpio L. cultivation, belong to aquaculture field.
Background technology
Cyprinus carpio L. is under the jurisdiction of Cypriniformes, Cyprinidae, Cyprinus carpio belong to, because of its robust body, gorgeous color, magnificent
Speckle, graceful stroke, docile habit and enjoy great prestige in the world, be referred to as " funny fellow's stone in water ", " be able to swim
The art work ".
Cyprinus carpio L. is through artificially breeding, the large-scale famous and precious fancy fishes of directive breeding by Cyprinus carpio mutant strain,
Body colour, decorative pattern change multiterminal, the contrast of body colour and mottle is also the important embodiment of ornamental value simultaneously.Day
In often producing, this fish can cultivate in outdoor ponds and cement pit, owing to cement pit cultured area is little, it is simple to
View and admire, sell, and closely overlook and view and admire and more can produce preferable visual effect, therefore, the most both at home and abroad
The cultivation of Cyprinus carpio L. focuses primarily upon cement pit cultivation.
The Cyprinus carpio L. cultivating high-quality is the highest to water quality requirement, and water quality adjustment is always indoor water mud sump cultivation brocade
The technical bottleneck of Cyprinus carpio.Circulating water culture system is considered breeding water always widely and is purified and recycling
The best approach, fundamentally saved water resource, improve utilization rate.
At present, China's circulating water cultivation is also provided with the development of considerable scale, but compared with world-technology, still
So there are water treatment facilities and operating cost is high, and water processes the problems such as frequency is low.
Summary of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide that a kind of operating cost is low, process frequency
The circulating water purification system of the Cyprinus carpio L. cultivation that rate is high.
To achieve these goals, the technical scheme is that the circulating water purification system that a kind of Cyprinus carpio L. cultivates,
Including culturing pool, it is characterised in that: arrange by described culturing pool Buffer Pool, coagulation pond, at two grades
Reason pond and tertiary treatment pond, described Buffer Pool, coagulation pond, two stage treatment pond and tertiary treatment pond along
The length direction of culturing pool is arranged in a row,
The top of the sidewall of described culturing pool arranges discharge outlet, and this discharge outlet connects with Buffer Pool, described buffering
The outlet in pond is positioned at the middle and upper part of its another sidewall, and the outlet of described Buffer Pool enters with coagulation pond
The mouth of a river connects, and the outlet in described coagulation pond connects with the water inlet in two stage treatment pond, at described two grades
The outlet in reason pond connects with the water inlet in tertiary treatment pond, and water inlet pipe and cultivation are passed through in described tertiary treatment pond
Pond connects, and described water inlet pipe is away from the discharge outlet of culturing pool, the height of the water inlet in described tertiary treatment pond
Degree is less than the height of water inlet pipe,
In described coagulation pond, filtration hairbrush is set, thin at the surface adsorption aerobic of described filtration hairbrush
Bacterium；The water inlet in described coagulation pond lays respectively at the middle and upper part of relative two sidewall with outlet；
Being provided with coral sand bag heap in described two stage treatment pond, described coral sand bag heap is near water inlet, institute
State and filter cotton, the surface adsorption of described filter cotton are set between coral sand bag heap and the outlet in two stage treatment pond
There is anaerobic bacteria；
It is placed with activated carbon bag and germicidal lamp in described tertiary treatment pond.
Using such scheme, the water in culturing pool constantly flows in Buffer Pool from discharge outlet, in Buffer Pool
Preliminary sedimentation effect can be played.Then the water in Buffer Pool flows into coagulation pond, in coagulation pond,
Being intercepted by hairbrush, play the effect of coarse filtration, water is purified under the effect of aerobic antibacterial.Then
Flowing into two stage treatment pond, here, water first passes around the filtration of coral sand, and coral sand refers to that Corallium Japonicum Kishinouye or shell are broken
Sheet, has the characteristic of sustained release calcium carbonate, and shape, granule, size are uneven, and micropore enriches, the most greatly
The biochemical bacteria live of amount, the effect there is stable pH, replenishing the calcium.
Under the effect of filter cotton, carry out three grades of purification filterings the most again, finally enter tertiary treatment pond, at this
In, activated carbon plays the effect of absorption harmful substance, and germicidal lamp plays the effect of sterilization, finally flow back into foster
Grow pond.So ceaselessly circulating, operating cost is low, processes frequency high, is suitable for the cultivation of Cyprinus carpio L..
Described Buffer Pool, coagulation pond, two stage treatment pond and tertiary treatment pond are along the length side of culturing pool
To being arranged in a row.Compact conformation, floor space is little.
In such scheme, described filtration hairbrush includes brush body and cross bar, the upper end of described brush body
Being lifted on cross bar, described cross bar is placed on the Chi Kou in coagulation pond.So it is convenient for changing filtration hairbrush.
In such scheme: described filter cotton includes filter cotton body and transverse bar, described filter cotton body
Upper end lifts on the transverse bar, and described transverse bar is placed on the Chi Kou in two stage treatment pond.It is convenient for changing filter cotton.
In such scheme: sewage draining exit is distributed at the bottom of the pond of described culturing pool, described in have sewage draining exit pass through pipe
Road is connected with blow-off pipe.The sewage being conveniently replaceable in culturing pool, and culturing pool is cleared up.
In such scheme: described Buffer Pool, coagulation pond, two stage treatment pond and the pond in tertiary treatment pond
Also sewage draining exit it is provided with at the end.It is easy to the cleaning to pond.
Beneficial effect: present configuration is simple, reasonable in design, construction cost is low, replacing is easy, need not
Power set, operating cost is low, continual to be processed water quality, can meet Cyprinus carpio L. and cultivate water quality
Requirement.
