Eco-Friendly Water Recycling Treatment System {SYSTEM FOR RECYCLING WATER}

The present invention relates to a water reuse treatment system that enables reuse of sewage, wastewater and rainwater for various purposes, and more specifically, the sewage, wastewater and rainwater can be physically and biologically purified and reused for artificial ponds and the like. In some cases, the recycled water can be recycled and purified to improve the efficiency of water reuse.In addition, it is possible to connect or replace renewable energy such as wind and solar power as a power source used in the operation of such a system. It is about environmentally friendly water reuse system.

Recently, the demand for water is rapidly increasing due to the industrialization and the improvement of living standard, and the demand for reusing water, living sewage, and factory wastewater is suggested to secure alternative water resources in the situation of deepening water shortage. Accordingly, the government is mandatory to introduce a heavy water facility to buildings that use a certain amount of water, and thus the need for technology development regarding water reuse is increasing. Here, heavy water means that water of water quality suitable for each application is not necessarily required as much as that of drinking water among many waters which are conventionally supplied by constant water. For example, for flushing toilet water, sprinkling water, and landscaping water, the criteria for residual chlorine should be detected and should be 0.2 mg / L or more. In addition, heavy water quality standards are proposed for each application in terms of appearance, turbidity, BOD, odor and pH.

On the other hand, as the water reuse treatment technology as heavy water, Korean Patent Publication No. 94-3872, "Sewage dewatering reuse apparatus", Korean Patent Publication No. 97-20963, "Water treatment system using membrane treatment and its operating method" And Korean Patent Publication No. 1999-33044, "Flow Control Aeration Tank and Ultrafiltration Membrane Water System."

As such a prior art, a biological treatment method (system) will be described as an example. Firstly, wastewater is first screened to remove coarse particles, and then a technique of dissolving organic matters in a biological treatment tank and discharging them for various uses is commonly used. Here, the biological treatment tank is generally composed of an anaerobic tank, an anaerobic tank, and an aeration tank. The wastewater and wastewater introduced into the anaerobic tank are decomposed and removed by methane gas and carbon dioxide by anaerobic microorganisms, and the accumulation of bacteria is associated with organic storage. Emits.

Subsequently, after passing through the anaerobic tank, the wastewater is supplied to an anoxic tank, which is the next step. In the anoxic tank, nitrous acid and nitric acid are converted into nitrogen gas and removed by denitrifying microorganisms. Then, the waste water is introduced into the aeration tank after the anoxic tank, and the organic matter contained therein is decomposed into carbon dioxide and water by the microorganism in the aeration tank, and ammonia nitrogen is nitrified to nitrous acid or nitric acid by the nitrifying microorganism. In addition, the accumulating bacteria are excessively ingested with phosphorus as oxidative decomposition of accumulated organic matter proceeds, and the phosphorus is removed in the form of sludge.

At this time, the aeration pipe is continuously disposed in the aeration tank by the blower in the bottom, and the injected air maintains the oxygen concentration in the aeration tank. In addition, the wastewater treated in the aeration tank is introduced into a separate sedimentation tank through a discharge pipe and discharged to the outside so as to reuse only the treated water in which the sludge has settled, and the sludge settled in the sedimentation tank by the sludge tank transport pump. The sludge, which is recycled into the tank and settled in the aeration tank, is recycled by an internal circulation pump.

However, these prior arts do not present an integrated model of technologies that can be reused as heavy water for sewage and wastewater, and technologies that can be reused as heavy water for rainwater. As necessary, there is a limit to its operation in islands, where it is difficult to link existing commercial power, and there is a problem in that it does not present any solution for recycling of water used as heavy water.

Therefore, the problem to be solved by the present invention can be integrated water reuse for the point source and non-point source, can operate the system irrespective of the local conditions, and use the treated water functionally to suit the purpose To provide a water recycling system that can be recycled.

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

Eco-friendly water reuse system of the present invention, as shown in Figure 1, the biofilm treatment tank 100 is composed of a detachable biofilm is introduced into the sewage, wastewater, screen tank 200, rainwater is introduced and the screen is formed therein, The treatment water flows from the biofilm treatment tank and the screen tank, and consists of a water storage treatment tank 300 including a sedimentation tank, an aeration tank, and a storage tank, and a means 400 for using the treated water in the water storage treatment tank. H. First, the rainwater and non-point source are treated firstly and treated in the water storage tank secondly so that the treated water is used in the means 400 such as the artificial pond 410 to recycle the water. Has a feature.

In addition, the use means 400 may operate the system without considering local conditions by selectively using the solar power or the like instead of the main power by the independent power management unit 600 selectively as needed, and save energy. To do it.

Hereinafter, with reference to Figure 2 will be described the operating state based on the flow of water in the eco-friendly water reuse system of the present invention.

Eco-friendly water reuse system of the present invention, the wastewater is introduced into the biofilm treatment tank (100). The biofilm treatment tank 100 has a biofilm 110 and the acid pipe 120 is formed at the bottom thereof to activate the aerobic microorganisms present in the biofilm 110, which are present in the wastewater and wastewater by the aerobic microorganisms. Organic matter decomposes. The diffuser 120 corresponds to a configuration of increasing dissolved oxygen (DO) by aeration of the oxygen (a1) supplied by the brower (b1) into the biofilm treatment tank (100).

In this way, the treated water w1 from which the organic matter is removed from the waste water is discharged to the water storage treatment tank 300 by the transfer pump p1.

On the other hand, in the case of rainwater is introduced into the screen tank 200, the solids and the like is filtered by the screen 210, the treated water (w2) is filtered in this way solids, etc. from the rainwater is not shown in the drawing, but by the pump or the overflow It is transferred to the water storage tank (300).

Thus, the treated water (w1, w2) from which the solids and organic matters are firstly removed from the wastewater and rainwater is secondarily purified by physical and biological treatment in the water storage tank 300.

First, in the sedimentation tank 310, foreign matters having a large specific gravity are settled to the lower part by free fall, and the treated water w3 from which the foreign matter has a large specific gravity is transferred to the aeration tank 320 by the monthly flow. In the aeration tank 320, an diffuser 321 is formed below the aeration tank 320 to increase the amount of dissolved oxygen (DO) inside the aeration tank 320. Aerobic microorganisms are activated, and organic matter present in sewage, wastewater and rainwater introduced by these aerobic microorganisms is decomposed. In this case, too, the blower b2 supplies oxygen to the diffuser 321. Based on this action, the aeration tank 320 decomposes organic matter by aerobic microorganisms and induces nitrification.

The treated water w4 from which the organic matter is removed from the aeration tank is introduced into the filtration chamber 330. The carrier 331 is embedded in the filtration chamber 330 to perform adsorption and filtration. The treated water w5 in which the biodegradation and particle filtration are performed through the filtration chamber 330 is stored in the storage tank 340 and introduced into the use means 400 according to the purpose. That is, for example, the inflow water w6 is introduced into the artificial pond 410, and in some cases, the water is circulated back to the storage tank 340 as the circulation water w9. In addition, the inflow water (w7) of the sprinkler 420 flows into the grass or the like is used.

On the other hand, in the water storage treatment tank 300, the back flow (w8) from the storage tank 340 to the settling tank 310 may be subjected to the purification process again. In this process, by supplying oxygen from the brower (b2) during the inflow (w8) to flow into the settling tank 310, it is possible to create an aerobic environment in the settling tank (310), by the inlet (w8) without the oxygen supply to the settling tank The reaction may be performed by an anoxic tank 310 to remove nitrogen through the denitrification process, which may be selectively operated according to the state of the treated water (w1, 2) flowing into the water storage tank 300. Of course it is.

Meanwhile, although not shown in FIG. 2, since the pumps p1 and 2 and the blowers b1 and 2 are powered by the independent power management unit 600, solar power and wind power may be used without or without electricity supply. This allows the system to work in island areas.

Hereinafter, the components of the present invention will be described with reference to FIGS. 3 to 7.

The biofilm treatment tank 100 is a biological treatment for the wastewater, which is introduced into the biofilm 110, so that the biofilm 110 can be attached, detached and height-adjusted in the biofilm treatment tank 100. It is configured to be easily attached and detached from the biofilm treatment tank 100 during the replacement and cleaning of the biofilm 110, the mounting of the biofilm 110 according to the flow rate of the waste water flowing into the biofilm treatment tank 100 The height can be adjusted. To this end, the biofilm 110 is configured with a biofilm frame 130 surrounding the outside so that the biofilm 110 is exposed to the outside, so that the biofilm frame 130 slides up and down while being in contact with the inner circumference thereof. Guide rail 140 is configured.

By this configuration, the installation height is adjusted up and down by sliding the biofilm frame 130 in the guide rail 140, it is easy to detach if necessary. The configuration for sliding the biofilm frame 130 up and down is not shown in the drawings, but can be slid on the guide rail 140 by pulling and releasing the string by hanging a string on the biofilm frame 130. Will be.

As shown in FIG. 4A, the screen tub 200 includes a plurality of screens 210 having an inclined gradient formed therein, and a rainwater inlet 230 is formed on an upper surface thereof, and an inspection opening 240 capable of opening and closing is provided. It is composed. Although not shown in the drawing, it is preferable that the screen 210 has a larger gap than the screen 210 located in the opposite direction of the screen 210 located in the rainwater inlet 230. In order to filter the foreign matter without interfering with the flow of water flowing through the inside by filtering the foreign matter from the screen 210 in order.

Meanwhile, the present invention provides a screen 210a of another embodiment as shown in FIG. 4B. The screen 210a of the present embodiment includes a screen frame 210a forming an outline, a plurality of support pins 212a formed in parallel with the screen frame 210a, and a vortex wing formed on the support pins 212a. 213a), the vortex wing (213a) is composed of the upper wing (213a-1) and the lower wing (213a-2), the upper wing (213a-1) and lower wing (213a-2) in the other direction Is to bend.

Here, the screen frame 210a is not limited in shape, but may be configured in a rectangular frame shape as shown in FIG. 4B. The support pins 212a are formed at one edge of the screen frame 210a and the other edge opposite to the screen frame 210a, and the gap is formed by the clearance between the support pins 212a. Preferably, the support pin 212a is appropriately configured at the upper edge of the screen frame 210a and the lower edge thereof, which is a foreign material filtered by a gap between the upper support pins 212a. This is to make it easier to clean by dropping the filtered foreign matter deposited on the lower surface of the screen tank 200 by making it easy to fall in the downward direction.

The vortex wing 213a is appropriately formed integrally with the support pin 212a, and is configured to protrude toward the rear side of the screen 210a (the direction in which water penetrates the gap). In particular, the vortex wing 213a is configured such that the upper wing 213a-1 and the lower wing 213a-2 are bent in the other direction, and thus, the plurality of vortex wings 213a-1 protrude to the rear side of the screen 210a in parallel. In the direction, each upper blade 213a-1 is configured to be bent in one direction in parallel, and in the lower direction, each lower wing 213a-2 is configured to be bent in the other direction in parallel. .

This is because the water filtered by the foreign matter by the gap between the support pins 212a passes through the gap between the support pins 212a, so that the upward flow W1 and the downward flow W2 are formed by the vortex wing 213a. The collision and vortices between the flow in the transverse and longitudinal directions are formed so that sludge, etc., passing through the gap are formed to have a floc (FLOC), so as to be caught on the screen 210a that is passed next or to be deposited on the lower surface. It will be able to increase, and then water is passed through the screen (210a) to be passed at acute angle, which is also to increase the foreign matter manure efficiency.

The water storage treatment tank 300 is divided into a sedimentation tank 310, an aeration tank 320, and a storage tank 340 by an inner partition wall, the aeration tank 320 is configured with a diffuser 311 in the lower storage tank The filtration chamber 330 is formed on the upper portion of the inner partition wall partitioned with the 340.

The settling tank 310 is to communicate with the biofilm treatment tank 100 and the screen tank 200 to filter the particles, the specific gravity is large by the inflow of wastewater and rainwater that is primarily treated. Water introduced into the settling tank flows to the aeration tank 320 by overflowing to the upper end of the first inner partition wall 371 while filtering the particles having a high specific gravity by the settling.

In the aeration tank 320, an acid pipe 311 is formed at the lower portion to create an aerobic environment, whereby organic matter is decomposed and nitrification proceeds.

The water in which the organic matter is decomposed in the aeration tank 320 is passed through the filtration chamber 330. The filtration chamber 330 is configured on the rear surface (surface contacting the reservoir) of the second inner partition wall 372. The inlet 331 is configured to allow the water passed through the aeration tank 320 to be introduced through the inlet 331. The inlet 331 is formed in the second inner partition wall 372 as shown in Figure 5a.

For this configuration, the second inner compartment wall 372 is formed to completely block the aeration tank 320 and the storage tank 340 so that water passing through the aeration tank 320 is introduced into the inlet 331. do. The water flowing into the inlet 331 flows upward from the downward direction of the filtration chamber 330, but passes through the carrier 333 to filter organic matter, solids, etc. by adsorption, filtration, and the like. Water passing through) is to flow to the reservoir 340 through the outlet 332 configured above the filtration chamber 330.

The carrier 333 may be appropriate to allow adsorption and filtration by embedding a s Korea 333-1 therein.

The scoria 333-1 is a kind of volcanic products. In Jeju Island, there are many Koreans called volcanic eruptions, also called Song. Jeju Island on Jeju Island is a volcanic rock material that contains volcanic rock, volcanic sand and other volcanic ashes. About 75% of the components of SK Korea are silicon oxide (SiO₂), aluminum oxide (Al₂O₃) and iron oxide (Fe₂O₃). In addition, calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (K ₂O) and sodium oxide (Na₂O) and nickel oxide (TiO₂). The shape of the sea Korea is porous and its specific surface area is about 100m₂ / g, which is relatively large, providing a good environment for microorganisms to grow. In addition, S Korea has physical and chemical and biological stability, high mechanical strength and durability, there is an economic advantage that can be used to collect natural materials.

In other words, by using the s Korea (333-1) as a carrier it is possible to filter by the adsorption of organic matter and the biological environment of the microorganisms can be formed by the porous material of the s Korea (333-1) to enable biological decomposition. .

In addition, SKOREA is characterized by suppressing the pH rise in the appropriate line as the pH is about 6 to 7. In other words, excessive pH increase in the purification of water may cause deactivation of microorganisms, thereby lowering the purification efficiency, and even when discharged as heavy water, the pH standard must be satisfied. pH rise can be suppressed by a titration line.

Meanwhile, in the present invention, as shown in FIG. 5B, an example in which the carrier ball 333-2 is further used together with the switch 333-1 as the carrier 333 is provided.

Here, the carrier ball (333-2) is characterized in that it has a ball shape by mixing 20 to 30 parts by weight of steelmaking slag, 5 to 10 parts by weight of water, 0.1 to 0.5 parts by weight of soil hardener. That is, the support ball 333-2 is manufactured in a spherical shape to form a constant particle by mixing the peat, steelmaking slag, water, soil hardener through a firing step.

The steelmaking slag can be divided into converter slag and electric furnace slag. The converter slag is a slag produced when melting raw steel, and is different from the electric furnace slag produced when melting scrap iron. Direct reduction of CAHs or reduction of hydrogen ions through oxidation can be expected. Steel slag is essentially lighter than iron and is separated by the difference in specific gravity, so it contains little heavy metal and thus has low environmental hazard.

The peat is a peat, such as moss, reeds, sedges and plants, or woody fluids, such as pine and birch, are thickly deposited in the basin, and are decomposed and altered by biochemical changes such as fungi in the presence of water. Peat is broadly included in one type of coal, but is generally distinct from coal.

Unlike peat, which is buried underground like coal, which has been fished under acupressure and geothermal action for many years, the main components of the plant are lignin and cellulose, which are mainly formed by decomposition in the surface.

In the present invention, peat includes all kinds of peat, but not limited to tundratan, peat, wood peat and the like.

In this way, the carrier ball 333-2 is made of steel slag and peat as a main component to reduce chlorine-based aliphatic carbohydrates (CAHs) as a hardly decomposable substance to induce dechlorination. In other words, the biofilm treatment tank 100 and the aeration tank 320 decompose the organic matter under an aerobic environment as a pretreatment, and decompose the organic matter by adsorption or the like as another carrier. Since the chlorine-based aliphatic carbohydrates (CAHs) as the material can be discharged with the treated water as it is, as shown in Figure 5b the filter chamber 330 as the carrier 333-1 and the carrier 333-1 and the carrier ball 333 -2) is mixed to remove degradable and hardly decomposable organic matter.

In particular, the carrier ball (333-2) is provided in the form of a ball by firing by appropriately mixing water and soil hardener in the steelmaking slag and peat, the porosity due to the microorganism propagation due to the long time reaction 333-1 By preventing this from falling, the flow of the fluid in the filtration chamber 330 is prevented from being lowered, thereby controlling the wall effect.

That is, by forming the proper pores in the carrier 333 by the ball carrier ball 333-2, the organic matter removal efficiency is reduced or the blockage is prevented.

As such, the carrier ball 333-2 is presenting an appropriate blending ratio in producing the ball form by mixing the steelmaking slag and the peat, and the blending ratio is limited to 20 to 30 parts by weight of steelmaking slag. It is reasonable. If the blending ratio of steelmaking slag exceeds 30 parts by weight, the pH will be 7.5 or more, and the alkalinity will not provide an environment suitable for the growth of microorganisms, and if it is less than 20 parts by weight, the removal rate of chlorine-based aliphatic carbohydrates will be reduced. .

Meanwhile, in the present invention, as shown in FIG. 5B, a plurality of diffuser devices 380 may be configured on the bottom of the aeration tank.

The diffuser 380 includes a hollow support 381 and a rotating plate 382 configured to be rotatable at an inner circumference of the upper end of the support, a spring 383 attached to an upper surface of the rotating plate 382, and the spring. It is attached to the (383) and formed integrally with the support protrusion (384-1) and the support protrusion (384-1) located on the inner circumference of the support, the spiral groove 384-2 is formed on the outer circumference and the diameter It consists of the rotary tool 384 which forms the head 384-4 of this enlarged shape.

The support 381 is configured on the lower surface of the aeration tank 320 to form a hollow so that the rotating plate 382 is configured to be rotatable on the inner circumference, and the spring 383 is applied to the upper surface of the rotating plate 382. Furnace rotary ball 384 is to be fastened to enable vibration and rotation.

The air diffuser 380 according to this configuration should be configured such that the head 384-4 is positioned above the diffuser 321, which is caused by the air injected from the diffuser 321. 4) By vibrating the structure of the spring 383 and the spiral groove 384-2, the water inside the aeration tank 320 is added to the vibration energy and rotational energy. That is, the air (oxygen) aerated by the addition of this energy is increased in the dissolved rate in the water stored in the aeration tank 320, this high dissolved rate is to activate the aerobic microorganisms to increase the decomposition efficiency of organic matter.

As such, by further configuring the diffuser 380 separately from the diffuser 321, the dissolution rate can be physically increased without increasing the electricity consumption, thereby enabling an environmentally friendly operation in terms of energy.

In addition, the vibration energy added by the air diffuser 380 may deactivate bacteria and the like, so that the effect of sterilization may be obtained at the same time.

On the other hand, the treated water purified by the above-described configuration can be used in the means 400 for various uses as heavy water, Figure 6 shows an artificial pond 410 as an example.

The artificial pond 410 has an artificial tank 411 configured to form an artificial pond by forming a space therein so that the treated water is stored. The artificial water tank 411 is not limited in shape and may be selectively considered according to the place where it is installed. An inlet pipe 412 is formed in the artificial water tank 411 to communicate with the storage tank 340 to introduce the treated water from the water storage tank 300 to the artificial water tank 411.

The inflow of the treated water from the reservoir 340 through the inlet pipe 412 is not shown in the figure, but will be possible due to the action of the pump. The inlet pipe 412 is installed higher than the height of the artificial water tank 411 is configured to communicate with the artificial waterfall 413. The artificial waterfall 413 has a storage space 413-1 communicating with the inflow pipe 412 at the top thereof, and falls down so that the treated water flowing over the storage space 413-1 can fall. -2) is configured to be exposed to the outside. That is, the treated water introduced into the inlet pipe 412 is stored in the storage space 413-1, and the treated water flowing out of the storage space 413-1 falls freely to the falling surface 413-2, thereby artificially falling. Will be configured.

Meanwhile, the water stored in the artificial water tank 411 may be discharged back to the storage tank 340 when the water level exceeds a predetermined level, so that the treated water may be circulated. To this end, the lower surface of the artificial water tank 411 is configured with a discharge pipe 414 communicating with the storage tank 340, and the water level control pipe is fastened to be detachable from the discharge pipe 414 and the artificial water tank 411 ( 415). The water level control pipe 415 may be configured to be detachable, by screwing and the like discharge pipe 414.

In addition, the cleaning pipe 416 is formed on the lower surface of the artificial water tank 411 and formed at a height lower than the level control pipe 415 while surrounding the water level control pipe 415, the cleaning pipe ( 416 is characterized in that the diameter is formed larger than the water level control tube 415 and configured to surround the water level control tube 415 and lower than the height of the water level control tube 415.

By constituting the discharge pipe 414, the water level control pipe 415 and the cleaning pipe 416 so that the water overflowing the height of the water level control pipe 415 is discharged to the reservoir 340 through the water level control pipe 415. The water level of the artificial water tank 411 is controlled by the water level control pipe 415, and when it is necessary to clean the foreign matter, etc. deposited in the artificial water tank 411, the water level control pipe 415 to the discharge pipe 414. By separating from the water of the artificial tank 411 is discharged to the discharge pipe 414 through the cleaning pipe 416 and the water level of the artificial tank 411 is adjusted to the height of the cleaning pipe 416.

The artificial water tank 411 is maintained by maintaining the original water level by lowering the water level to clean the artificial water tank 411, and then fastening the water level control pipe 415 to the discharge pipe 414.

Meanwhile, in the present invention, the stand-alone power management unit 600 is configured to be used as an auxiliary or main power source for solar power and wind power, so that it can be used without regard to local conditions such as island areas, and save energy. So that water can be recycled in an environmentally sound manner.

In this way, the power generated from the auxiliary power supply unit 620 is stored in the wastewater processing unit 630. The battery unit 630 is connected to the charge / discharge controller 640, and the power of the auxiliary power stored in the battery unit 630 is charged and discharged in real time under the control of the charge / discharge controller 640.

Here, the charge / discharge controller 640 compensates for mutual drawbacks from clean energy such as wind power generation or solar power generation and supplies power to a load required by storing energy in the battery unit 630. For example, wind power can be generated 24 hours, but the output fluctuates severely, and wind speed tends to be low in summer and high in winter.

On the other hand, solar power can only be generated during the daytime when the sun is present, and solar radiation tends to be higher in summer and lower in winter than wind. As described above, power generated by mutually generating power depending on sunset, sunrise, or season is stored in the battery unit 630 through the charge / discharge controller 640.

In addition to the charge and discharge controller 640 may include a power processing unit 650, overcharge protection unit 660 and reverse voltage protection unit 670. The power processing unit 650 processes the power stored in the battery unit 630 from the auxiliary power supply unit 620 so as to correspond to the use voltage of the load.

That is, the power processing unit 650 outputs the power stored in the battery unit 630 to a power suitable for the voltage used for the load, and a converter such as an inverter or a converter may be included for this purpose. The overcharge preventing unit 660 extends the life of the battery unit 630 by preventing overcharging of power stored in the battery unit 630 from the auxiliary power supply unit 620. In addition, the reverse voltage protection unit 620 protects the load of the battery unit 630 and the pump, blower and the like connected to the charge and discharge controller 640 by blocking the reverse voltage of the power generated through the auxiliary power supply unit 620 do.

On the other hand, the control unit 650 is connected to the charge and discharge controller 640 and the main power supply 610, and performs a real-time monitoring of the main power supplied to the load, such as pumps, blowers, and to determine the power cut situation for the main power The auxiliary power is supplied to the main power in general or to the load in general by adjusting the supply amounts of the auxiliary power and the main power delivered from the charge / discharge controller 640.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
