The priming mud and the pond water come from a simulated water body. The thickness of the priming mud is at least 20 cm, the water level in the pond is 2 m. The water-in holes and water-out holes can be equi-spaced in symmetric and array way. The distance between layers is 40 cm. The water-in holes and water-out holes of each layer can be arranged horizontally in lines. The hole diameter is 0.6 cm, hole distance is 0.3 cm.

Description

But the water plants breeding test tank of simulated flow

Technical field

The utility model relates to the experimental rig that carries out water pollution improvement with water plants, but a kind of water plants breeding test tank of simulated flow particularly is applicable to that water plants is put in a suitable place to breed, aquatic plant purification water body, water plants interspecies competition, aquatile population competition experiments.

Background technology

Comparatively severe contamination has appearred in the most of water bodys of China, especially the lake eutrophication of middle and lower reach of Yangtze River area serious threat continuous development of society economy, government drops into the control that substantial contribution is used for eutrophication, has carried out the control that external source is polluted.But owing to enter the detergent power that water pollutant content surpasses water body, water ecosystem is badly damaged, water plants disappears, repair water ecosystem, rebuild aquatic vegetation group, illustrate the effect of water plants in water body is repaired, and understand fully that competition becomes China's water environment treatment and improves important content between the aquatile population, therefore need carry out a large amount of water plants breeding tests.But because natural water body is subject to multiple factor restriction, interaction process complexity between each factor is difficult to obtain ideal results.Therefore, need at sharpness of border, correlation test is carried out in having in certain area and the volume that current are controlled.

Prior art is most relevant with life staying idle at home and swimming pool, and the part pond has water body circulation and water level management function, but can not be used for the simulation of current.Existing water plants is put the pond in a suitable place to breed and has also only considered water inlet and water outlet, does not consider wherein current control, is difficult to simulate the natural water body actual conditions, obtains correlated results and often has certain difference with natural water body.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of possess make stream and but water plants is put the water plants breeding test tank of the simulated flow of plantation function in a suitable place to breed, be applicable to that water plants is put in a suitable place to breed, aquatic plant purification water quality, water plants interspecies competition, aquatile population competition experiments.

Above-mentioned purpose of the present utility model is realized by following technical scheme: but the water plants breeding test tank of simulated flow, it is characterized in that being provided with experimental tank, basin bottom is equipped with bed mud, is risen by the bed mud top layer on two relative walls of pond, lays at interval into and out of the water hole to higher slice; One side is the inlet opening, and the inlet opening of each layer is in charge of by water inlet separately and by-pass valve control is communicated to water inlet manifold; One side is an apopore, and the apopore of each layer is in charge of by water outlet separately and by-pass valve control is communicated to total outlet pipe; Pass through the water pump communication loop between water inlet manifold and the total outlet pipe.Bed mud and Chi Shui take from the water body of simulating, and bed mud thickness is 20cm at least, and water level in water pool 2m can symmetry into and out of the water hole, array is uniform, and interlayer is every 40cm.But each layer arrange aperture 0.6cm, pitch-row 0.3cm into and out of the water hole horizontal linear.

Advantage of the present utility model and effect: on the basis of traditional experimental tank, on two relative walls of pond by the pond at the bottom of to 2.0m water level place at interval 40cm lay the queueing discipline high density into and out of the water hole, self priming pump with the band water meter, make the pool inner water body produce circulation manufacture of intraocular current, and then simulate flowing of natural water body, make the pond have the function of research current to the aquatic ecosystem influence.

Fig. 2 is the utility model water inlet wall schematic diagram;

Embodiment

Referring to Fig. 1,2, experimental tank can be made into 4.5m * 4.5m * 2.2m, and thick bed mud 1 desirable lake mud or the river silt of 20cm injects the water body of studying the waters, and water level 2m is advisable.Be five layers into and out of the water hole, interlayer is advisable every 40cm.The inlet opening 2 of each layer by water inlet separately be in charge of 3 and the water inlet control valve door be communicated to water inlet manifold 5; The apopore 6 of each layer by water outlet separately be in charge of 7 and the outlet water control valve door be communicated to total outlet pipe 9; But 2,6 horizontal linears into and out of the water hole of each layer are arranged, aperture 0.6cm, pitch-row 0.3cm.Can be communicated with the realization water circulation by the self priming pump of band water meter between water inlet manifold and the total outlet pipe.

When carrying out current to the influence of aquatic plants growth or to water ecosystem influence test, at first in the pond, plant the target water plants, and inject the water body in research waters in the pond, close the water outlet battle array hole aqueduct valve of the water body that do not submerge, connect the power initiation self priming pump, just can make and produce interior circulation in the pond.According to the current of being simulated, switch is in the by-pass valve control of different water layer battle arrays hole water pipe, can be in the pond manufacture level stream, tiltedly sinking, oblique upwelling etc.

(1) can carry out the hydrostatic condition water plants and put test (not starting self priming pump) in a suitable place to breed;

(2) can carry out under the horizontal flow condition that water plants is put in a suitable place to breed and water body community competition test (by-pass valve control of corresponding water layer battle array hole water pipe is all and opens or closes);

(3) can carry out under the oblique sinking condition water plants puts with the water body community competition test in a suitable place to breed (by-pass valve control of 1,2 water layer battle array hole water pipes is opened among Fig. 1,4, the by-pass valve control of 5 water layer battle array hole water pipes is closed, the by-pass valve control of 4,5 water layer battle array hole water pipes is opened among Fig. 2, and the by-pass valve control of 1,2 water layer battle array hole water pipes is closed);

(4) can carry out under the oblique upwelling condition water plants puts with the water body community competition test in a suitable place to breed (by-pass valve control of 1,2 water layer battle array hole water pipes is closed among Fig. 1,4, the by-pass valve control of 5 water layer battle array hole water pipes is opened, the by-pass valve control of 4,5 water layer battle array hole water pipes is closed among Fig. 2, and the by-pass valve control of 1,2 water layer battle array hole water pipes is opened);

(5) a plurality of ponds are used the water plants that can carry out under Different Nutrition salt, the different flow condition and put in a suitable place to breed with the water body community competition and test;

(6) a plurality of ponds are used the water plants that can carry out under the different depth of waters, the different flow condition and put in a suitable place to breed with the water body community competition and test.

The utility model is set up 12 ponds in Taihu Lake lake ecosystem research station of the Chinese Academy of Sciences, has carried out the test of putting in a suitable place to breed of Taihu Lake p.malaianus, has obtained effect preferably, and tentatively disclosing current influences aquatic plants growth.
