It is discharged to the river after passing through.

3 and 4, the electrode unit 410, a plurality of support ends 411 and radially symmetrically installed with respect to the center on the lower side of the tank cover 432 to be described later, and the support end 411 includes first and second electrodes 412 and 143 which are installed to face each other in a state spaced apart from each other. Due to this structure, the plurality of first and second electrode pairs 412 and 413 are arranged radially symmetrically with respect to the center of the tank cover 432, and accordingly, the electricity of the pretreatment water in the treatment tank 430 is Decomposition is evenly distributed.

The activated carbon filtration unit 420 removes the odor component contained in the treated water sterilized by the electrode unit 410 and simultaneously filters the fine foreign matter contained in the treated water. As shown in FIG. 2, the activated carbon filtration unit 420 is filled in a substantially middle lower side of the treatment tank 430, and thus the treated water sterilized by the electrode unit 410 is activated carbon filtration unit ( It passes naturally through the 420 is discharged through the outlet pipe 450. Here, the activated charcoal filtration unit 420 should not have a gap with the inner circumferential surface of the treatment tank 430 so that the sterilized treated water may pass completely through the activated carbon filtration unit 420. ) Consists of numerous granule-type activated carbon particles.

As shown in FIG. 3, the treatment tank 430 has a large size of 1,000 liters or more, is opened to the upper side, and the activated carbon filtration unit 420 is built in, and an outlet pipe 450 is installed at the bottom side. A tank body 431; Covered to be sealed on the upper side of the tank body 431, the tank cover 432 on which the electrode unit 410 is installed; It includes; a tank door 433 for discharging the activated carbon filtration unit 420 is installed on the lower side wall of the tank body 431 to be replaced.

The bottom of the tank body 431 forms a hopper downward toward the center, the outlet pipe 450 is formed in the center of the bottom of the tank body 431. Accordingly, the treated water passing through the activated carbon filtration unit 420 flows out naturally to the outlet pipe 450.

The tank cover 432 is coupled to be sealed to the upper portion of the tank body 431, the pretreatment water introduced through the inlet pipe 440 does not overflow from the treatment tank 430.

The tank door 433 is installed at the lower side of the tank body 431 to discharge the activated carbon filter 420 to be replaced. As described above, since the tank body 431 is filled with a large amount of activated carbon amounting to 400 to 500 liters, the tank body 431 is disposed on the lower side of the tank body 431 in order to easily replace the activated carbon filter 420. The tank door 433 is provided.

Activated carbon filtration unit 420 located on the lower side of the electrode unit 410, as shown in Figure 2, is filled up to approximately the middle portion of the tank body 431, as described above the processing tank 430 Since the capacity of the large size of 1,000 liters, the volume of activated carbon filtration unit 420 to be filled is very large enough to reach 400 to 500 liters. Therefore, when the activated carbon filter 420 is to be replaced, it is difficult to actually discharge the activated carbon filter 420 to the upper side of the tank body 410 in the state that the tank cover 432 is opened.

However, in the present invention, by installing the tank door 433 which is opened and closed on the lower side of the tank body 431, the activated carbon filtration unit 420 can be easily discharged in the state where the tank door 433 is opened, thereby Replacement of activated charcoal filter becomes easy.

The flow rate control valve 460 is installed in the outlet pipe 450 to control the flow rate of the treated water flowing out, thereby controlling the flow rate of the pretreated water flowing into the inlet pipe 440. The flow control valve 460 is composed of a solenoid or motor-mounted valve for controlling the flow rate by an electric signal applied from the outside.

The washing water supply control valve 470 is installed at the upper side of the tank cover 432, and controls the flow rate of the washing water supplied by the washing water supply line 475 to wash the inside of the treatment tank 430. Supply. The washing water is to remove the protein adsorbed to the activated carbon filtration unit 420 embedded in the treatment tank 430, or to remove foreign substances stuck to the inner surface of the treatment tank 430, and chemicals for decomposing proteins as necessary. Drugs may be added.

The odor measurement sensor unit 480 measures the odor component remaining in the treated water via the flow control valve 460 and generates a corresponding measurement signal. The measurement signal is transmitted to the controller, and the controller controls the operation of the electrode unit 410, the pressure pump 300, the flow control valve 460, and the washing water supply control valve 470.

(a) When the value of the measurement signal generated by the malodor measuring sensor unit 480, that is, the malodorous component of the treated water is larger than the set value, the activated carbon filter 420 may not remove the malodorous component contained in the pretreated water. In this case, the measurement signal generated by the odor measuring sensor unit 480 reduces the discharge flow rate of the flow control valve 460 so that the pretreatment water stays in the post-treatment filter unit 400 for a relatively long time. In 420, the odor is removed by passing it for a long time.

(b) When the value of the measurement signal generated from the malodor measuring sensor unit 480, that is, the malodorous component of the treated water is excessively smaller than the set value, that is, smaller than the predetermined value, the pretreatment water filter 400 is more than necessary. To stay long). In this case, the measurement signal generated by the odor measuring sensor unit 480 controls the pressure feed pump 300 so that a large amount of pretreatment water is pumped to the post-treatment filter 400 to shorten the time spent.

(c) A large amount of protein in the activated charcoal filter 420 when the value of the measurement signal generated from the malodor measuring sensor unit 480, that is, the malodorous component of the treated water is excessively larger than the set value, that is, greater than a predetermined value. Is adsorbed and does not function to remove odor components. In this case, the measurement signal generated from the odor measuring sensor unit 480 operates the washing water supply control valve 470 to separate the protein adsorbed to the activated carbon filtration unit 420 by introducing the washing water into the post-treatment filter unit 400. Remove At this time, while the washing water is introduced, the measurement signal applies a reverse voltage to the electrode unit 410 to separate the polar foreign matter adhered to the first and second electrodes 412 and 413 during the washing.

That is, the odor measuring sensor unit 480 measures the odor component remaining in the treated water and then generates a corresponding measurement signal, thereby controlling the electrode unit 410, the pump pump 300, the flow control valve 460, and the washing water supply control. The valve 470 is appropriately controlled.

Next, the operation relationship of the steaming wastewater treatment apparatus of the present invention will be described.

The wastewater supplied from the wastewater storage tank 100 is filtered while a relatively large foreign material is filtered through the pretreatment filtration unit 200, and then introduced into the posttreatment filtration unit 400 by the pump 300.

Thereafter, in the post-treatment filter 400, the electrode unit 410 sterilizes bacteria and enzymes in the wastewater, and activated carbon filtration unit 420 removes the odor components already generated in the wastewater and then drains them.

At this time, as the bacteria and enzymes are sterilized, the metabolic action of proteins in the wastewater by bacteria and enzymes is prevented, thereby preventing the generation of ammonia nitrogen and nitrogen compounds, which are major components of odor. Therefore, the treated water can be recycled in the steaming process, and even when the treated water is discharged into the river, no odorous components or nitrogen compounds that cause green algae remain, thereby preventing the environment from being polluted. In particular, since HCl generated by the electrolysis reaction of the electrode unit 410 remains in the treated water, it is possible to prevent odors over time.

As described above, according to the present invention, sterilization and odor treatment are performed on the protein-containing wastewater generated during the laver processing by using the electrode unit 410 and the activated carbon filtration unit 420, so that the treated water can be reused in the laver processing. In addition, it can prevent the occurrence of odor or green algae when discharged into the river.

In addition, since the wastewater treatment proceeds through the pretreatment filtration unit 200 and the posttreatment filtration unit 400, a large amount of wastewater can be treated.

The odor measuring sensor unit 480 measures a residual odor component remaining in the treated water processed by the post-treatment filter 400 to generate a corresponding signal, and the signal is an electrode unit 410 and a pump pump 300. ), The flow rate control valve 460 and the washing water supply control valve 470 can be used to eventually treat the treated water uniformly.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
