The present invention relates to a water treatment apparatus using an electric device in the field of water treatment technology, and more particularly, to a water treatment apparatus using an electric device such as an underground water, a river water, a rain water inflow water, a building water depth, industrial wastewater containing refractory substances, The present invention relates to a water treatment apparatus using an electric device that can easily cope with an increase / decrease of a treatment capacity through a simple structure in which only the number of modules is increased or decreased according to a treatment capacity.

In recent years, it has been difficult to secure sufficient quality agricultural water as the groundwater is seriously polluted due to an increase in daily sewage discharge due to rapid urbanization and an excessive use of chemical fertilizer and pesticide.

Generally, water used in rural areas uses water such as ground water, river water or reservoir. However, wastewater discharged from farmhouses of various farms such as poultry farms, pig farms, cow farms, etc., Processing.

In order to purify the water used in rural areas, ozone is usually mixed and used. However, since the ozone mixed with water is mostly separated into gas and discharged again, the purification effect by ozone is insignificant, It is not in the state.

In addition, in urban areas, there are a number of storerooms that can be used as water resources while preventing storm flooding by laying storm reservoirs underground in parking lots, playgrounds, parks, etc. However, .

In addition, due to the rapid expansion of the industrial scale, various factories are producing serious amounts of industrial wastewater containing harmful heavy metals and various toxic organic substances causing serious social problems.

Accordingly, although the related industry makes great efforts to prevent water pollution, since the kinds of industrial wastewater are so wide and the industrial wastewater contains decomposable organic substances, it is difficult to completely clean the industrial wastewater have.

Recently, the electrolysis method has attracted attention as one of the methods for treating the water containing the polluted water, especially the refractory organic substance. Recently, the basic principle of the electrolysis method is well known that the electrode is immersed in the electrolyte solution, , The ions in the aqueous solution move to the opposite polarity to each other and hydrogen gas is generated in the cathode and oxygen gas is generated in the anode and the generated hydrogen and oxygen gas are oxidized and reduced, The secondary reaction causes decomposition of pollutants.

Therefore, the water treatment apparatus using the electrolysis method has an excellent effect on the reduction of biological oxygen demand (BOD) and chemical oxygen demand (COD), decolorization and deodorization.

As an example of the above-described water treatment apparatus, there has been known a water treatment apparatus in which cathodes, quadrangular plates, plate-like cathodes and anodes are alternately arranged in an electrolytic bath having a rectangular shell shape.

However, in the water treatment apparatus having the above-described conventional electrode, the number of electrodes and the size of the electrolytic bath must be adjusted in order to increase or decrease the processing capacity.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

Prior to a specific description of the present invention, the present invention uses most of the configuration of the above-mentioned Patent No. 10-0477945 as it is. Therefore, the contents of the above-mentioned registered patent will be quoted as it is in the basic structure described below.

1 and 2, a water treatment apparatus using an electric device according to the present invention includes a water treatment facility 10, which includes a cylindrical electrolytic bath 12, an electrolytic bath 12, And an electrode 14 inside.

The electrolytic bath 12 includes a cylindrical body 12a having an untreated water inlet pipe 16a and a treated water drain pipe 16b and a cylindrical body 12a sealing both open ends of the body 12a, And a sealing cap 12b for mounting an electrode 14 provided inside the cap 12b.

At this time, the end of the body 12a is provided with a flange 12a 'to be fitted into the sealing cap 12b.

Therefore, the installation work of the body 12a can be easily performed.

In addition, the electrode 14, to which both end portions are fixedly fitted to the sealing cap 12b in the same manner as the body 12a, is provided with first and second positive electrodes 14a and 14c and a negative electrode 14b. The first and second anodes 14a, 14c and the cathode 14b are cylindrically shaped with different diameters.

Therefore, as shown in the drawing, the cathode 14b may be provided inside the first anode 14a and the second anode 14c may be provided inside the cathode 14b.

The sealing plate 12b is provided with wire insertion holes (not shown) in which electric wires 18 for applying power to the positive electrodes 14a and 14c and the negative electrode 14b are inserted.

At this time, in order to prevent the water to be treated from leaking to the outside of the electrolytic cell 12 through the wire insertion hole, the wire insertion hole is sealed with the sealing material 20 or the like after inserting the wire 18.

The positive electrodes 14a and 14c and the negative electrode 14b of the present embodiment are each made of a wire mesh type so that the oxidizing / reducing action of the for-treatment water can be smoothly performed inside the electrolytic bath 12, (DSA: Dimensionally Stable Anode) in which a metal oxide film such as iridium, ruthenium, or platinum is formed on titanium.

Thus, when the water to be treated (sewage and wastewater) flows through the WTBT inlet pipe 16a, oxidation occurs in the anode 14a, 14c, and reduction occurs in the cathode 14b.

At this time, since the present invention includes two anodes 14a and 14c, it is possible to effectively remove the biological oxygen demand, the chemical oxygen demand, the chromaticity, the ammonia nitrogen, and the smell.

In the water treatment apparatus of the present invention having the above-described configuration, several electrolytic baths 12 are arranged in series or in parallel according to the processing capacity, and the adjacent electrolytic baths and the piping (the water to be treated inlet pipe and the treated water drain pipe) Can be used in conjunction.

In addition, in the present invention, as in the example of FIG. 3, a pretreatment unit PUT and a sedimentation tank ACC are further provided before the electrolytic bath 12.

Thus, the treatment object water is pretreated through the pretreatment unit PUT and drained to the sedimentation tank ACC in a state where the solids are removed therefrom. In the sedimentation tank ACC, only the overflow amount of the overflow is introduced into the electrolytic tank 12 So that the electrolytic treatment can be performed through the electrolytic bath 12 in a state where the solid content is completely removed through the removal of the secondary solid content.

At this time, the preprocessing unit PUT includes the fixed frame 100 as shown in FIGS. 4 and 5.

The fixed frame 100 is a support for supporting the preprocessing unit PUT.

Since the stationary frame 100 is a support, the stationary frame 100 is not limited to the shape but is preferably disposed in a substantially. Shape.

A cylindrical compression housing 200 is fixed to the upper end of the fixed frame 100 and a crushing housing 300 having a shape corresponding to one end of the compression housing 200 is fixed to the flange.

Therefore, the inside of the compression housing 200 becomes a compression chamber, and the inside of the crushing housing 300 becomes a crushing chamber, and functions to crush and compress inflow water including solid contents charged into the crushing housing 300.

An inlet port 400 is connected to the crushing housing 300 and a solid outlet pipe 500 is connected to the outer circumferential surface of one end of the compression housing 200.

At this time, the solenoid-type opening / closing valve 510 is installed in the solid discharge pipe 500 and is opened only when a certain amount of solid content is filled.

Meanwhile, the compression housing 200 is formed in a double pipe shape to prevent a leakage problem, and further includes a separate discharge pipe DR for the exterior.

A compression screw 230 having an inner space is provided in an inner tube of the compression housing 200 and a first screw shaft 232 of a tubular body communicating with an empty hollow at one end surface of the compression screw 230, And the other end surface of the compression screw 230 is kept in a closed state. The second screw shaft 234, which is exposed to the outside through the crushing housing 300 at the center of the crushing section, .

The second screw shaft 234 is rotatably received by the power of the driving motor M through a power coupling means such as a chain or a belt.

The hollow inner diameter of the first screw shaft 232 forms the water passage PW and the primary filtered water discharged through the water passage PW is moved to the sedimentation tank ACC and stored.

5, the compression screw 230 is provided with a water supply passage PW at one end thereof with a feeding region S including a screw portion 236 and a private portion 238 therebetween, And a second screw shaft 234 receiving a rotational driving force by a driving motor M is fixed to the other end.

Particularly, the screw portion 236 is formed so as to have a smaller diameter as the diameter of the screw portion 236 increases toward the private portion 238, thereby increasing the compressive force.

A plurality of through holes N are formed in a part of the outer circumferential surface of the screw portion 236. A filter box FTP is assembled to the through holes N so as to be disassembled by a screw fastening method.

Therefore, as the number of the object including the solid component moves to the private part 238 by the compression screw 230, the filtered water filtered through the filter cylinder FTP flows into the inner diameter of the compression screw 230, And flows into the settling tank ACC through the water passage PW formed in the inner diameter of the shaft 232. [

Then, the remaining solids are compressed by the pressurizing unit 238, and when a certain amount is reached, the solenoid-type on-off valve 510 is opened and falls down to be separately collected.

In addition, the filter barrel (FTP) may be clogged by the solid matter. In this case, if an air pulse is connected to the water flow path PW while the installation is stopped, the solid content that has been attached to the filter box FTP by pulsing is discharged to the inner pipe, thereby solving the clogging phenomenon. Of course, if it is completely fixed, it is possible to remove the compression screw 230 by setting the repair period, unscrew the filter cylinder (FTP) and replace it with a new one.

A plurality of blades 310 may be provided at a predetermined interval in the second screw shaft 234 disposed inside the shredding housing 300 to completely break solid components.

In addition, the inlet cover 400 may be rotatably installed in the inflow inlet 400 so that the opened upper portion of the inflow inlet 400 may be covered when not in use to prevent foreign matter from entering the inflow inlet 400.

In addition, the flocculant may be further injected through the inflow water injection unit 400 to increase the cohesion of the solid content depending on the condition of the water to be treated.

Such a flocculant is used for accelerating flocculation reaction and accelerating flocculation and accelerating the separation of solids by cohesion in a short time. The flocculant is composed of 10% by weight of kale powder, 5% by weight of fresh persimmon juice, 25% by weight of ataplastite, An eco-friendly material consisting of 15% by weight of rosin fiber, 5% by weight of polyacrylamide and the balance calcium hydroxide is preferable.

In this case, the kale powder is obtained by ripening the leaves and roots of kale which is a perennial plant of the poppy tree cabbage and then pulverizing it, and is added to enhance the adsorption power by the abundant fiber and to extinguish harmful substances and to remove odor.

And, the fresh persimmon juice is a plant of the persimmon family, which is extracted from the fresh persimmon which is an herbaceous perennial plant. It is added because it contains a large amount of flavonoid and germanium and is useful for removing toxic substances and reducing odor.

In addition, in the present invention, ataplatite is added for thickening and bulking, but it is added in order to increase the adsorption capacity by using the characteristic of the fibrous structure in the state where the discharge of harmful substances is blocked.

In addition, the granule type cellulose fibers are natural adsorbents, and are added to contribute to toxic and absorptive, environmentally friendly materials, as well as contributing to the removal of odors.

In addition, slaked lime is a representative coagulant and is the most base material.

Further, if the compression housing 200 and the crushing housing 300 are made of metal, the cost is high and the rustproofing process is required to prevent corrosion. Therefore, the initial equipment cost is rapidly increased. In the present invention, 8.0 wt% of sorbitan olivate, 2.5 wt% of hydroxyproline, and 2.5 wt% of butylprop-2 are used to provide durability and corrosion resistance, chemical resistance and chemical resistance. 15 wt% of butyl prop-2-enoate, 10 wt% of urosolic acid, 2.0 wt% of water-soluble SiO ₃ salt, 3.0 wt% of oregano oil, 2.5 wt% of isohexadecane, 5.0 wt% of cyanoacrylate, 8.5 wt% of perfluoropolyether, 3.5 wt% of methacrylic acid, 2.5 wt% of silicon nitride, 4.5 wt% of calcined ytterbium, 0.5 wt% of alumina 1.5% by weight, and the rest of the polycarbonate resin.

Here, the sorbitan olivate is a monoester of fatty acid derived from sorbitol-derived hexitolanhydride and olive oil, and is added to enhance natural emulsification function due to the enhancement of the surface activity to improve moldability, The proline is added to the gelatin hydrolyzate to increase the flexibility of the resin composition by increasing the flexibility of the resin composition as it is gelatinized when it is heated in the drying process described later as a ligne salt.

The butyl-2-enoate is added to increase the bending strength while providing ductility, impact reinforcement and binding property to the composition, and the uronic acid is a powder having excellent needle-like absorbability and adsorbs the polymer particles on the surface of the inorganic material Is added to improve bufferability, bending properties and durability and crack resistance.

Also, the water-soluble SiO ₃ is added in order to eliminate the toxicity and is added to eliminate the harmfulness of the human body, and it is added in order to increase the usability of the human body by adsorbing and eliminating the six harmful substances such as heavy metals which are inevitably contained, and the oregano oil It is added for the antimicrobial function to sterilize Norovirus or Rotavirus which is a common bacteria that can often be dissolved in washing water.

In addition, the isohexadecane is added so as to contribute to separation and removal of foreign substances adhering to the surface of the molded article, and the cyanoacrylate is added to suppress the high thermal expansion and to enhance the binding force between the compositions .

And, the perfluoropolyether increases the slip property to reduce the friction resistance with the solid content, thereby inducing the transfer. The methacrylic acid is added to maintain corrosion resistance because it is resistant to acid, and the silicon nitride is added Amorphous nano-sized particles of boron nitride are dispersed to absorb heat shock to suppress micro cracks and to enhance corrosion resistance.

In addition, the sintered ytterbium oxide is added as a rare earth metal to increase the chemical resistance and chemical resistance while increasing the durability through grain refinement, and the alumina is added as an oxide of aluminum in order to improve the heat resistance.

In addition, the polycarbonate resin is added as a base resin in order to strengthen and maintain scratch resistance and crack resistance.
