On the other hand, at the point where the pipe 110 and the filter module 120 is in contact with the sensing module that can detect the presence of the filter module 120 is installed, the sensing module is a terminal unit 150 to be described later to the current filter module It conveys information on how many 120 are installed.

The filter module 120 removes contaminants by filtering river water flowing from the pipe 110, and is provided along a length direction of the pipe 110 provided in plurality. The filter module 120 may be installed in a form detachable to the pipe (110).

According to the detachable filter module 120 as described above, the operator can easily vary the pretreatment filtration capacity easily. According to the filter module 120, when the pollution degree of the river water is changed, there is an effect that the operator can easily operate the pretreatment device in response to this.

On the other hand, using the BOD value predicted by the calculation unit 140 to be described later, it is possible to quickly determine the degree of the river water to the terminal unit 150, the terminal unit 150 is required filter module 120 based on the BOD value Since it is possible to display the number of installation of the pipe 110, the filter module 120, the measuring unit 130, the calculating unit 140 and the terminal unit 150, according to the degree of contamination of the river water filtration of the pretreatment device The effect of taking timely dose adjustment can be expected.

The measuring unit 130 measures the amount of suspended solids in the river water and is disposed in the collecting unit 10 so as to be in contact with the river water, and is connected to the calculating unit 140 which will be described later. To pass.

Suspended Solids (SS) refers to the amount of substances (mg / L or ppm) having a particle diameter of 2 mm or less, where the suspended solids are solids containing organics and organics suspended in water without being dissolved in water. do. More specifically, suspended matter refers to suspended matter that is not filtered when the stream water sample is filtered using filter paper with 0.1% porosity.

The method of measuring the amount of suspended solids has traditionally been measured by filtering a stream water sample, collecting the solids, drying them, and then calculating the concentration of the solids by the difference in weight before and after, and expressing the concentration in mg / L or ppm. Real-time measurement method using is also used.

Meanwhile, as shown in FIG. 4, the measuring unit 130 may include a main body 131, a sensor 132, and a removal module 133 in more detail.

The main body 131 forms an inflow space S, which is a space into which the river water flows, at one end thereof, and a sensor 132 and a removal module 133 which are described later are installed therein, and the electrical power generated by the sensor 132 is provided. A circuit or the like for transmitting a signal to arithmetic unit 140 to be described later is installed therein.

When the excitation is generated in the main body 131 according to the flow of the river water, the sensor 132 installed in the main body 131 may also vibrate, causing errors in the measurement of the amount of suspended solids. Therefore, the main body 131 is preferably provided with a device (gyro sensor 132 and actuator) for detecting the shaking, vibration of the main body 131 to physically compensate the vibration value to the sensor 132.

The sensor 132 measures the amount of suspended matter in the river water by irradiating infrared rays into the inflow space S. The sensor 132 is installed in the above-described main body 131 and electrically connected to the calculation unit 140 described later to measure the amount of suspended matter. Transfer to operation unit 140.

In detail, the sensor 132 analyzes a pattern in which infrared rays are changed by suspended matter included in river water flowing in the inflow space S in the process of irradiating infrared rays into the inflow space S and receiving the reflected infrared rays. Measure the amount of suspended solids. Since the sensor 132 as described above can measure the amount of suspended matter in the river water in real time using infrared rays, according to the sensor 132 can obtain a function value for the amount of suspended matter over time.

The removal module 133 removes foreign matters such as water plants when foreign matters such as water plants enter the inflow space and interferes with sensing of the sensor 132. The removal module 133 rotates by a motor and a motor that provides rotational force, and the like. It may consist of a blade to remove.

The blade may be provided to be movable up and down. When the sensor 132 monitors the sensing situation and determines that a few seconds or the like flows into the inflow space, the blade is lowered by an alarm signal generated by the sensor 132. Go to. Then, the blade is rotated by the operation of the motor, when a few seconds or the like is removed by the rotation, the blade is stopped by the confirmation signal generated by the sensor 132, and moves upward.

According to the removal module 133 operating in the above-described process, the effect of significantly reducing the sensing error of the sensor 132 due to the inflow of foreign matter, such as water plants, which may occur when measuring the amount of suspended solids in the river or water source. There is.

Is displayed externally.

The behavior of suspended solids has been studied to have a pattern similar to that of BOD. Therefore, if the behavior of suspended solids is known, the behavior of BOD can be predicted in a similar form.

As shown in FIG. 5, the calculating unit 140 may predict the BOD value based on a pattern that changes according to the behavior of the amount of suspended solids in the river water. According to the real-time suspended solids value measured by the sensor 132, a function value for the suspended solids amount over time can be derived, and this function value corresponds to the behavior of the suspended solids amount as described above. If the value reflects the characteristics of the stream water and the weight of the state of the river, the function value, that is, the behavior of the current river water BOD value can be predicted.

According to the prediction operation of the operation unit 140 as described above, it is possible to easily predict the BOD value by using a relatively easy measurement of the amount of floating material of the infrared type without having to go through a complicated process to confirm the BOD value.

The terminal unit 150 is connected to the communication unit 140 so as to be communicable, and receives the BOD value from the operation unit 140 and displays it externally. The terminal unit 150 may be provided as a terminal device such as a smart phone. Can be.

A dedicated application is installed in the terminal unit 150. According to the dedicated application, the amount of suspended matter, the BOD value, etc. at the location where the measuring unit 130 is installed may be monitored in real time, and the state of contamination of the sensor 132 may be achieved. And the like can also be confirmed.

In addition, the terminal unit 150 may be communicatively connected to the sensing module installed in the pipe 110 described above to check and display how many filter modules 120 are present in the pipe 110.

The dedicated application installed in the terminal unit 150 calculates the required capacity in the preprocessing process based on the BOD value of the calculating unit 140, thereby calculating the number of filter modules 120 to be installed in the pipe 110. Mark it for confirmation.
