Description

High speed sewage treatment device {HIGH SPEED SEWAGE REDISPOSAL MECHANISM}

The present invention relates to a high speed sewage reprocessing apparatus for reprocessing and discharging sewage in a sedimentation tank at high speed, and more particularly, to a high speed sewage reprocessing apparatus for removing sludge generated while supplying ions into sewage.

In general, wastewater and sewage treatment methods cultivate microorganisms in aerobic conditions by forced aeration using various organic and inorganic substances contained in contaminated wastewater and sewage, and circulate the microorganisms and wastewater by circulating the cultured wastewater and sewage. Most biological treatment methods using microorganisms that remove various organic and inorganic substances contained in the process through gradual processes such as oxidation, decomposition, aggregation, adsorption, and precipitation have been adopted. There is a method and a mixture of these methods, and in the active sludge method, organic matter mainly consumes bacteria and fungi, whereas biofilm method has an overwhelming number of protozoa, especially ciliated larvae, and plays an important role in wastewater treatment.

However, the biological wastewater treatment apparatus by the activated sludge method must maintain the active sludge concentration in the aeration tank at any time, so that the procedure of detecting and testing the activated sludge concentration in the aeration tank as well as returning the activated sludge from the final sedimentation basin to the aeration tank is required. Since it is required to install a separate sludge return pump at the bottom of the final sedimentation basin, and to connect the final sedimentation basin and the aeration tank to the return pipe, there was a problem requiring the top equipment investment and operating costs.

In addition, biological wastewater treatment by a biofilm should prepare a carrier having a suitable material, size, and structure to attach and grow microorganisms in advance, and since the microorganisms are directly attached to the carrier in a steady state, efficient use of dissolved oxygen can be prevented. There was a problem that was impaired.

In addition, in order to apply the activated sludge process or biofilm method for sewage treatment, not only a large space and many facilities are required, but also the purification of sewage is performed for a long time, and thus the throughput is inefficient due to the size of the facility.

The conventional sewage purification apparatus using the ions to improve this problem has a problem that the bubbles are generated with the sludge due to the air supplied to the sewage with the ions while the sewage is purified by the ions and accumulated in the upper layer of the sewage.

In order to improve the above problems, an object of the present invention is to provide a high-speed wastewater reprocessing apparatus for effectively removing bubbles generated with sludge from the wastewater being purified by supplying ions to the wastewater stored in the chamber.

A separate blower is provided to control the operation of the blower.

In addition, the sludge discharge passage 120 is formed on the upper one side of the plurality of chambers 110 to be lower than the height of the plurality of chambers 110 so that the sludge foam 600 generated in the upper portion of the sewage can flow over. The sludge foam discharged from the chamber 110 is formed to be inclined so as to be discharged through the sludge discharge port 121.

As shown in FIG. 2, the ion supply unit 400 supplies a DC pulse supply unit 410 for supplying a DC pulse voltage at a constant frequency, and serves as a ground electrode, and supplies a DC pulse voltage output from the DC pulse supply unit 410. An insulating tube 431 formed on an outer circumferential surface of the receiving coil 432 so as to be inserted into the inner circumferential surface, and a heat dissipating conductor 433 for dissipating heat generated from the coil 432 to correspond to the coil 432; Ion discharge portion 430, an insulating tube made of an insulating tube 434 formed of a tube or a tape on the outer peripheral surface of the insulating tube 431 to generate more ions and guide the generated ions to move inside the 431 A blower 420 for generating wind so that the ions generated from the 431 can move smoothly, and for discharging the ions discharged from the insulating tube 434 of the ion discharge unit 430 to the ion supply pipe 130. It consists of a pump 450.

The operation of the high speed wastewater treatment apparatus according to the present invention configured as described above will be described.

First, the control unit 500 selects one or a plurality of chambers into which wastewater is introduced from the plurality of chambers, and opens a corresponding wastewater inlet valve 211 so that the wastewater inlet pipe from the existing purification tank, that is, the settling tank 200 ( Sewage flowing through 210 is introduced into the chamber 110.

At this time, one of the plurality of chambers 110 is always empty so that the newly introduced sewage from the sedimentation tank 200 is introduced so that the newly introduced sewage from the sedimentation tank 200 is already treated or processed sewage in the chamber 110. Do not mix with.

The sewage inflow valve 211 is opened under the control of the controller 500 so that the sewage in the sedimentation tank 200 is introduced into the chamber 110 through the sewage inflow pipe 210. Detects the amount of sewage flowing in from and outputs a sewage amount detection signal to the controller 500.

When the predetermined amount of sewage is filled in the chamber 110 according to the sewage amount detection signal, the controller 500 locks the sewage inlet valve 211 so that no further sewage may be introduced.

As such, when a predetermined amount of sewage is filled in the chamber 110, the control unit 500 operates the ion supply unit 400 so that ions are supplied into the chamber 110 through the ion supply pipe 130.

That is, when the ion supply unit 400 operates to generate ions, the control unit 500 opens the ion inlet valve 131 and receives ions introduced from the ion supply unit 400 through the ion supply pipe 130. 132 is introduced into the chamber 110.

Hereinafter, the process of generating ions in the ion supply unit 400 will be described in detail.

In the DC pulse supply unit 410 of the ion supply unit 400, when the DC pulse is generated at a constant frequency of 500 Hz or more and supplied to the coil 432 under the control of the control unit 500, the coil 432 is a heat radiating conductor 433. ) And charge and discharge by the insulating tube 431 and the insulating tube 434 to generate ions.

The generated ions are introduced into the ion pump 450 from the insulating tube 431 through the insulating tube 434 by the wind generated from the blower 420 and the ion pump 450 discharges them to the ion supply tube 130. And it is introduced into the chamber 110 through the ion inlet valve 131 and the ion inlet 132 open under the control of the control unit 500.

Since the generated ions are introduced together with the air through the ion inlet 132 installed in the lower portion of the chamber 110, vortices are generated in the sewage, so that the introduced ions and the sewage can be mixed smoothly.

When a certain time elapses while the sewage and ions are mixed by the vortex, impurities in the sewage are combined with ions to purify the sewage, and the ions combined with the impurities are raised to the sewage level in the form of sludge foam 600.

As such, when the sludge foam 600 floats on the water surface after a predetermined time has elapsed, the control unit 500 operates the blower unit 300 and the air inlet valve 311 toward the sludge discharge path 120. Allow the sludge foam 600 to move.

That is, the control unit 500 operates the blower unit 300 while supplying ions, and opens the air inlet valve 311 so that the air, that is, the wind blows in the direction of the sludge discharge path 120, causes sludge foam 600. The sludge discharge path 120 is moved.

At this time, the sludge discharge passage 120 and the boundary of the chamber 110 in the sludge discharge passage 120 installed on the upper side of the chamber 110 is made lower than the boundary between the peripheral chamber 110, the sludge foam to the adjacent chamber Do not fall to the sludge discharge passage 120.

On the other hand, when the sewage purification apparatus is made small, the blower 300 is provided by installing a separate blower for each chamber, it is only necessary to control the operation of each blower.

The sludge foam 600 passed to the sludge discharge path 120 is discharged to the sludge discharge port 121 through the slope, and then flows back into the settling tank 200 to continue the above-described purification process.

Since the sedimentation tank 200 performs the sludge removal operation periodically, a separate sludge removal operation is not required in the high speed sewage purification apparatus according to the present invention.

In addition, the controller 500 controls the sewage inlet valve 211 to allow the sludge foam 600 to smoothly flow into the sludge discharge passage 120.

That is, when the sewage is filled in the chamber 110 and the sewage amount detection signal is output from the sewage amount sensor 150 to the controller 500, the controller 500 controls the sewage inlet valve 211 to control the sewage inlet 212. A small amount of sewage is continuously introduced into the chamber 110 through). If a small amount of sewage is continuously introduced while the chamber 110 is full of sewage, the sewage is discharged toward the sludge discharge path 120 because the boundary with the sludge discharge path 120 is lower than that of a neighboring chamber. At this time, since the wind blows from the blower part 300 toward the sludge discharge path 120, the sludge foam 600 floating on the surface of the sewage is passed along with the sewage overflowing toward the sludge discharge path 120.

In another method, the controller 500 periodically opens the sewage inlet valve 211 to remove the sludge foam on the surface while passing the sewage in the direction of the sludge discharge passage 120.

As such, when the sludge foam 600 is removed and the sewage is completely purged after a predetermined time, the controller 500 controls the sewage inlet valve 211, the air inlet valve 311, and the ion inlet valve 131. While the sewage, air and ions are not introduced into the chamber 110, the sewage discharge valve 141 of the sewage discharge pipe 140 of the chamber 110 is opened to discharge the sewage treated through the sewage discharge port 142 to the outside. Be sure to

After all of the purified sewage in the chamber 110 is discharged, the controller 500 closes the sewage discharge valve 141 and controls the sewage inlet valve 211 to introduce the sewage to be treated again.

However, the sewage to be treated is continuously introduced from the sedimentation tank 200, so the newly introduced sewage during the sewage treatment in another chamber filled with sewage without any other reason, for example, sludge foam removal, etc. When introduced into the chamber being used, the existing treatment sewage and the newly treated sewage are mixed to reduce the sewage purification effect. Therefore, always prepare an empty chamber so that the newly introduced sewage is introduced into the empty sewage.

That is, after one chamber is empty and two chambers are empty after the wastewater treatment of the other chamber is completed and discharged through the open wastewater discharge valve 141, when the wastewater is introduced into the one chamber, The chamber will be empty, allowing new wastewater to enter.

Thus, since the degree of purification of the sewage is changed according to the order introduced into the chamber in the storage tank for purifying the sewage, the sewage inlet valve 211 is prevented from mixing the sewage with much purification and the sewage without purification. Control the water to ensure the correct purification of the sewage.

As described above, the high speed wastewater purification apparatus has the following effects.

First, the sludge bubbles generated by the ions can be smoothly removed.

Secondly, since the generated sludge is continuously introduced into the sedimentation tank, it is not necessary to provide a separate filter at the discharge port where the treated sewage is discharged, and thus the maintenance is convenient and no additional cost is required.

Third, since the storage tank for purifying sewage is divided into a plurality of chambers to perform separate sewage purification in each chamber, the treated sewage and the sewage to be treated are not mixed, and the sewage purification effect is increased.
