The filtration rate measuring device comprises an experimental water tank (1) and is characterized in that a water inlet pipe (2) and a water outlet pipe (3) are communicated with two ends of the experimental water tank (1) respectively, the other end of the water inlet pipe (2) is communicated with a diversion water tank (4), an overflow pipe (5) is further arranged on a side wall of the upper part of the diversion water tank (4) which is communicated with a water storage tank (6) through a diversion water tank water inlet pipe (11), an air stone (8) connected with an oxygen aeration pump (7) is arranged in the water storage tank (6), a water inlet regulating valve (9) is arranged on the diversion water tank water inlet pipe (11), and a water outlet regulating valve (10) is arranged on the water outlet pipe (3). The filtration rate measuring device for the filter feeding shellfish is simple in structure, unique in design, small in size and convenient to maintain, and can measure the filtration rate more accurately.
Description
Technical field
The utility model relates to a kind of biological nature determinator, particularly a kind of filter-feeding shellfish filtration rate determinator.
Background technology
Filtration rate refers to the water volume that filter feeder filters filter various suspension organic granular in drinking water within the unit interval time, and it is the important parameter of research filter-feeding bivalve shellfish energetic supersession.Traditional filter-feeding shellfish filtration rate assay method adopts hydrostatic experimental method mostly, in the container of certain volume, add the seawater of known algae concentration, afterwards experiment shellfish is put into container, through measuring after a period of time the situation of change of algae concentration in seawater, with the filtration rate of this experiment with computing shellfish.But along with the increase of experimental period, in experiment seawater, the chemical factors such as content of concentration, dissolved oxygen DO and the ammonia nitrogen of algae all can change, and this variation can affect the accuracy of measurement result.In addition, the instrument and equipment using due to different researchers is not quite similar, and larger to the measurement result difference of filter-feeding shellfish filtration rate, experimental result is also difficult to directly compare.Therefore need now a kind of novel filter-feeding shellfish filtration rate determinator that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, and volume is little, easy to maintenance, the filter-feeding shellfish filtration rate determinator that can measure filtration rate comparatively accurately.
Technical solution of the present utility model is: a kind of filter-feeding shellfish filtration rate determinator, comprise experimental trough 1, it is characterized in that: be communicated with respectively water inlet pipe 2 and rising pipe 3 at the two ends of described experimental trough 1, the other end of water inlet pipe 2 is communicated with shunting water channel 4, in the upper portion side wall of shunting water channel 4, also offer run-down pipe 5, shunting water channel 4 is communicated with aqua storage tank 6 by shunting water channel water inlet pipe 11, in aqua storage tank 6, be provided with the gas stone 8 being connected with oxygen increasing pump 7, on shunting water channel water inlet pipe 11, be provided with inlet regulating valve 9, on rising pipe 3, be provided with out water regulating valve 10.
Described shunting water channel water inlet pipe 11 places are also provided with water pump.
Compared with the existing technology, tool has the following advantages the utility model:
The filter-feeding shellfish filtration rate determinator of this kind of version, it is simple in structure, designs ingenious, rationally distributed.It is for the defect of traditional filtration rate measuring, design and a kind ofly can in experimentation, keep the constant structure of chemical factors such as algae concentration, dissolved oxygen DO and ammonia-nitrogen content in seawater, make the natural living condition of the more approaching experiment of experiment condition shellfish, thereby guarantee that measurement result is more accurate.Adopt identical experimental provision, can accurately compare the filtration rate of different filter-feeding shellfishes, also can better compare different researchers' experimental result.And its manufacture craft is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of filter-feeding shellfish filtration rate determinator, comprise experimental trough 1, be communicated with respectively water inlet pipe 2 and rising pipe 3 at the two ends of experimental trough 1, on rising pipe 3, be provided with out water regulating valve 10, the other end of water inlet pipe 2 is connected with shunting water channel 4, and the top at shunting water channel 4 sidewalls also offers run-down pipe 5, and shunting water channel 4 is connected with aqua storage tank 6 by shunting water channel water inlet pipe 11, in aqua storage tank 6, be provided with the gas stone 8 being connected with oxygen increasing pump 7, on shunting water channel water inlet pipe 11, be also provided with inlet regulating valve 9 simultaneously, and 11 places are also provided with water pump at shunting water channel water inlet pipe.
The course of work of the filter-feeding shellfish filtration rate determinator of the utility model embodiment is as follows: need to carry out determination experiment time, filter-feeding shellfish is put in experimental trough 1, and in aqua storage tank 6, pack the seawater or the fresh water that contain finite concentration algae into, gas stone 8 is put into water, open oxygen increasing pump 7, with being uniformly distributed of the dissolved oxygen content in maintenance water and algae, then open out water regulating valve 10 and inlet regulating valve 9, because the water level of the water table ratio shunting water channel 4 in aqua storage tank 6 is high, under the effect of gravitional force, (also can drive water body flow by water pump), water in aqua storage tank 6 flows in shunting water channel 4 and experimental trough 1 successively, until water slowly overflows from run-down pipe 5 He in rising pipe 3, regulate each valve, the state that keeps sluggish flow to overflow, to guarantee the constant of water flow in rising pipe 3.Gather and measure the Chlorophyll-a Content in water in run-down pipe 5 and rising pipe 3, and the flow of spill stream in rising pipe 3, the filtration rate of experiment with computing shellfish.
Computing formula is as follows:
cR=(
c 1-
c 2)/
c 1×
v, wherein
cR(L h
-1) be filtration rate,
c 1(μ g L
-1) be the Chlorophyll-a Content in water in run-down pipe 5,
c 2(μ g L
-1) be the Chlorophyll-a Content in water in rising pipe 3,
v(L h
-1) be the flow of spill stream in rising pipe 3.
Claims (2)
1. a filter-feeding shellfish filtration rate determinator, comprise experimental trough (1), it is characterized in that: be communicated with respectively water inlet pipe (2) and rising pipe (3) at the two ends of described experimental trough (1), the other end of water inlet pipe (2) is communicated with shunting water channel (4), in the upper portion side wall of shunting water channel (4), also offer run-down pipe (5), shunting water channel (4) is communicated with aqua storage tank (6) by shunting water channel water inlet pipe (11), in aqua storage tank (6), be provided with the gas stone (8) being connected with oxygen increasing pump (7), on shunting water channel water inlet pipe (11), be provided with inlet regulating valve (9), on rising pipe (3), be provided with out water regulating valve (10).
