Description

CCTV System for Backwash Timing forecast Observation of Activated Carbon Absorption Condition}

The present invention relates to a CCTV system for predicting backwashing time by observing the state of adsorption of activated carbon, and more particularly, by accurately photographing the surface of the activated carbon in the activated carbon adsorption pond, and detecting the state of adsorption of foreign substances on the surface of the activated carbon based on the captured image. It is related to a CCTV system for predicting backwashing time through observation of the activated carbon adsorption state, which determines whether or not the activated carbon is adsorbed and outputs it to a display device according to the determination result to efficiently predict the activated carbon backwashing time.

Conventionally, water treatment was carried out by performing the standard water purification processes such as coagulation/sedimentation and sand filtration. The process alone could not treat tap water in an appropriate state for drinking. In order to prevent this, in recent years, an advanced water purification technique that combines ozone and activated carbon processes with a standard water purification process has been introduced and implemented.

The advanced water purification process is the standard water purification process, such as coagulation/sedimentation and sand filtration, then oxidizes organic matter in water contained in raw water using ozone with excellent oxidizing power, and finally adsorbs activated carbon to a trace amount. By removing harmful substances, treatment efficiency is improved.

In the advanced water purification process described above, the sand filter process solves problems such as mudballs on the surface of the filtration layer, an increase in head loss, and leakage of turbidity substances through backwashing. . Similarly, in the activated carbon adsorption process, periodic backwashing should be performed to prevent excessive head loss caused by suspended materials accumulated in the adsorption layer and to prevent leakage of micro-activated carbon and pathogenic microorganisms. Here, in addition to the above-mentioned problems occurring in the sand filtration process, the loss of activated carbon and the difficulty in determining the time of backwashing due to changes in the water quality of the activated carbon treated water are important problems during backwashing of the activated carbon process. In other words, since activated carbon has a small density, there is a possibility that a lot of activated carbon may be lost during backwashing. Also, if the operation time of the activated carbon adsorption site is prolonged, microorganisms with reduced activity among microorganisms attached to the surface of activated carbon leak and drink the treated water. This is because there is a risk of harm to the health of the person who does it.

In determining the regeneration time of activated carbon, if the water quality is better than the treatment target water quality, it can be judged as the regeneration time. If the timing is judged as the regeneration time, it is difficult to reflect the residual adsorption capacity of the activated carbon, and since the activated carbon is expensive, it may be an uneconomical regeneration.

The above problem is a cause for the activated carbon treatment manager to make the determination of the regeneration time based on subjective judgment.

Contour detection detects the adsorption state of activated carbon by changing the brightness of the pixel, and the change in brightness is detected using gradient and Laplacian differential operation,
The storage unit 340 stores and manages the image received by the receiving unit 310, but stores and manages the image for the still image used in the detection unit 320 and the determination result for the image of the still image,
Further comprising an air device 500 adjacent to the driving device 200,
The air device 500,
a switch sensing means 510 coupled to the sliding body 230 of the driving device 200, lifting and lowering together with the sliding body 230, and configured to have the same length as the photographing device 100;
a switch 530 installed on the fixed frame 520 and turned on/off through the elevation of the switch detection means 510 coupled to the sliding body 230;
an air driving unit 540 for injecting air through the air discharging units 550 and 550' when the switch 530 is operated; and
The air delivered from the air driving unit 540 is sprayed to the photographing device 100 while the switch 530 is operated, and the injection position is adjustable, and the air discharge units 550 and 550' composed of one or more );
A CCTV system for predicting backwash timing through observation of the activated carbon adsorption state, characterized in that it comprises a. delete delete delete delete
