The culture unit 10 may be composed of a material and a structure that can insulate the storage space therein. And, the front of the culture unit 10 is provided with a door 13 for selectively opening and closing the front of the culture unit 10.

The inside of the culture unit 10 is provided with a plurality of storage containers 11 for containing the culture sample. The storage container 11 contains a sample of an appeal or a river to be measured.

The inside of the culture unit 10 is provided with a power pump (not shown) for pumping the culture sample contained in the storage container 11 to the top. The culture sample pumped upward by the power pump is supplied to the water tank 20 with the moving water to be described below. The power pump maintains a constant flow rate of the culture sample supplied to the tank 20 to the mobile water supply.

An upper part of the culture unit 10 may be provided with a cooling and heating unit 15 for maintaining the internal temperature of the culture unit 10. The air conditioning unit 15 is composed of an air conditioner (air-conditioner) and a hot air heater may maintain the internal temperature of the culture unit (10).

The upper portion of the culture unit 10 is provided with a temperature control unit 17 for controlling the air conditioning unit (15). The temperature control unit 17 may control the operation of the air conditioning unit 15 to maintain the control temperature input by the operator.

The upper portion of the culture unit 10 is provided with a mobile channel 20 is formed in a variety of intervals of the channel. The mobile water tank 20 is provided with a water tank unit 21 through which a culture sample flows, and the water tank unit 21 is formed in a substantially rectangular shape with an upper surface open. The tank 21 is provided with a support leg 23 so that the tank 21 is supported on the upper surface of the culture unit 10.

A plurality of through holes 25 are formed on the front and rear surfaces of the water tank unit 21, and the moving tube 27 is connected to the through holes 25. The moving tube 27 penetrates the upper surface of the culture unit 10 and is connected to the storage container 11 provided in the culture unit 10. Therefore, the culture sample stored in the storage container 11 is supplied to the mobile channel 20 through the mobile tube 27 by the power motor, the sample supplied to the mobile channel 20 is the mobile tube By discharging to the mobile water tank 20 through the 27 can be continuously circulated.

In the inner space of the water tank unit 21 is provided with partition walls 29 spaced at various intervals. Moving partitions spaced at various intervals are formed in the inner space of the tank portion 21 by the partition wall 29.

The flow velocity formed by the moving channel formed in the tank 21 directly affects the production of algae. Therefore, in order to form various flow rate conditions in the algae generating environment, the flow rate is determined by Equation 1 below.

Q = A · V

(Q: flow rate, A: channel cross-sectional area, V: channel flow rate)

According to [Equation 1], it can be seen that the flow rate is determined according to the change in the cross-sectional area of the water flow channel when the flow rate is kept constant. Therefore, by adjusting the width of the channel while supplying the same flow rate, it is possible to change the flow velocity of each channel. In general, the average flow rate of the domestic river is 0.1 ~ 0.4m / s, the flow rate of each of the flow channel formed in the tank 21 is 0.1m / s, 0.2m / s, 0.3m / s, 0.4m / s It is preferable to adjust the width of the movement channel so as to.

The spacing of the partition wall 29 may be configured to vary. As shown in FIG. 2, the partition wall 29 may be inserted into the insertion groove 31 formed at a predetermined interval on the bottom surface of the water tank 21 to adjust the gap between the partition walls 29. . One end of the partition wall 29 is opened so that each of the moving channels communicates with each other.

The bottom surface of the tank 21 may be seated on the plurality of fixing protrusions 33 formed on one side of the tank 21 to adjust the inclination. Since the lake or river where the algae is generated may flow with a constant inclination, it is possible to form a state similar to the environment in which the algae is generated by adjusting the inclination of the bottom surface of the tank 21.

The bottom surface of the tank 21 is provided with an algae 35 such as gravel for generating algae. The algae forming body 35 may be made of various materials such as gravel, sand or mesh, but is preferably composed of gravel to check the generation state of algae.

When the algae form 35 is composed of gravel, the particle size of the gravel is formed about 1 ~ 2cm, natural gravel and white gravel are arranged while alternately at intervals of 15cm. White pebbles are intended to facilitate visual observation of algal formation.

The light control unit 40 for dimming the water tank unit 21 is provided above the water tank unit 21. The light control unit 40 is provided with a frame 41 supported by the water tank unit 21 by four supports, and the frame 41 is provided with a plurality of light sources 43. A light blocking film 45 may be formed on an outer surface of the frame 41 to prevent light from being emitted to the outside.

Hereinafter will be described in detail the operation of the algae generating apparatus according to the present invention having the configuration as described above.

Each storage container 11 provided in the culture unit 10 stores a culture sample of an appeal or a river to be tested. The culture unit 10 is maintained at a constant temperature by the air conditioning unit (15).

In addition, the culture sample stored in the storage container 11 is supplied to the movement channel 20 through the moving tube 27 by the power motor in the culture unit 10. The culture sample supplied to the mobile water tank 20 is generated by the light supplied by the light control unit 40 while moving along the mobile water channel in the water tank 21.

Since the flow channels formed in the water tank unit 21 have different widths by the partition walls 29, the flow rates in the respective flow channels are different. Therefore, by examining the amount of algae generated in the culture sample moving at different flow rates after a certain period of time, it is possible to determine the amount of algae generated by the flow rate change.

4 to 6 show the results of experimenting with the algae generation amount using the algae generation test apparatus according to the present invention. Culture samples were taken from A and B rivers, the temperature set in the culture unit 10 was maintained at 25 ° C, the flow rate was adjusted to 0.1 ~ 0.4 m / s, the average flow rate range of the Korean river.

Five days after the experiment, blue light began to be observed, and after 15 days, the gravel turned blue as shown in FIG. 5. Results for the concentration of algae (chl-a) generated in the gravel in the mobile water tank 20 are shown in Table 1, Table 2 and FIG. 6 below.

According to the results, first, the algae concentration of river A, which has high pollution, was higher than that of river B. In terms of flow rates, algae concentrations of 0.1 m / s and 0.2 m / s were similar, but 0.3. At flow rates above m / s, algal concentrations have been reduced by more than 50%.

According to this, it can be seen that the amount of algae can be controlled by the flow rate under the same conditions of temperature and water quality. Therefore, the amount of algae can be controlled by adjusting the flow rate in the design of artificial rivers and artificial hoses.

In the scope of the basic technical spirit of the present invention, many modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the claims which will be described later. .

According to the algae generation test apparatus according to the present invention as described in detail above has the following advantages.
