Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a flock monitoring device of a water treatment facility.

Generally tap water is produced by passing through mixing basin, flocculation basin, sedimentation basin and filter basin.

In the mixed soil, flocculant is provided in the raw water containing a large amount of foreign matter from the water source, and foreign substances are solidified in the form of floc by the flocculant.

The raw water in which the flocs are formed in the mixed paper is provided as a cohesive paper, and the size and the number of the flocs are increased in the cohesive paper.

The raw water is supplied to the sedimentation basin, and the flocs are precipitated in the sedimentation basin. The raw water in which the flocs are precipitated is supplied to the filter paper from the sedimentation basin, and flocs and other foreign matter are completely filtered from the filter paper to produce tap water.

In this water treatment process, it is very important to solidify the foreign substances contained in the raw water into flocs.

In particular, when the amount of coagulant supplied to the raw water is insufficient compared to the foreign substances contained in the raw water, the flocs are not formed smoothly, and the foreign matter is not completely removed from the raw water, so that it is difficult to drink with drinking water.

On the other hand, when the amount of coagulant supplied to the raw water is larger than the amount of the foreign material, the coagulant remains in the raw water and is difficult to drink as drinking water.

Therefore, the number of flocs and the size of the flocs formed in the raw water by the coagulant provided in the raw water are monitored in real time, and the amount of coagulant supplied to the raw water by the monitoring result is feedback-controlled.

As a method for monitoring the number of flocs formed in the raw water, Korean Patent No. 10-0448560 and Floc measurement system of cohesive paper (registered on September 3, 2004) are representative.

In the floc measurement system of the coagulant, a floc characteristic of the coagulant is measured by an image acquisition device fixed to the coagulant to control the coagulant stirring speed and the coagulant input amount.

However, since the flock measuring system of the flocculation paper monitors the flocs from the image capturing device capturing the water surface of the flocculating paper in a state fixed to the flocculating paper, it is difficult to monitor the size and number of flocs according to the depth of the water surface of the flocculating paper

Also, since the flocculation system of the flocculation paper is fixedly arranged, it is difficult to accurately monitor the position of the flocculation paper, for example, the size and number of flocs at the edge of the flocculation paper or the central part of the flocculation paper.

In addition, in the flock measurement system of the cohesive paper, the camera is always disposed at the lower part of the water surface, and moss and the like are easily attached to the lens part of the camera by the raw water, thereby requiring a separate washing pipe or the like for monitoring flocs.

The flock measuring system of the cohesive paper is very difficult to clean the camera completely because it cleans the image stroke device by the flushing pipe disposed below the water surface of the raw water.

Further, the floc measurement system of the aggregation paper does not include a member for comparing the size and the number per unit area of the floc, and thus it is difficult to accurately calculate the actual size of the floc and the number per unit area.

The combination of the light generated from the LEDs 424 including the red light emitting diode, the green light emitting diode, and the blue light emitting diode can generate the flock color and the complementary color light, which is a complementary color, from the light source 420.

For example, red light may be generated from the light source 420 when the hue of the flock is generally green, and white light may be generated from the light source 420 when the hue of the flock is black.

The light guide plate (LGT) 430 changes the nonuniform luminance distribution of the complementary color light generated from the LED 424 as the point light source into a planar light source having a uniform luminance distribution. A reflection plate for preventing light from leaking to the rear surface of the light guide plate 430 may be disposed on the rear surface of the light guide plate 430.

As the grid pattern 442 and the flock are taken together in the camera 300, the image processing unit analyzes the grid pattern 442 and the image of the flock to determine the actual size of the flock based on the grid pattern 442, The number can be analyzed.

Particularly, by using the complementary color light generating unit 400 as in the embodiment of the present invention, the number and size of the flocs can be measured more precisely by using the color of the flock and the complementary light.

Although a transparent film 440 having a grid pattern formed on the entire surface of the light guide plate 430 is shown and described in the embodiment of the present invention, A grid frame 450 for a flock coefficient formed in the horizontal direction and the vertical direction may be provided between the complementary color light generating unit 400 and the camera 300 without using the light source 440. Alternatively, a pattern may be printed on the entire surface of the light guide plate in the form of a lattice frame.
