The present invention relates to an advanced water treatment apparatus and method for branching water supply pipes into a plurality of water pipes to separately control the amount of water supply according to the purification treatment capacity for each branch pipe.

In addition, the present invention, in the high-purification treatment of the treated water in the purification treatment apparatus, the treated water distributed to the water supply pipe is adsorbed, decomposed and primary filtered on the biofilm filter mat in which the biofilm is formed, the surface of the mat The organic material contained in the wastewater is filtered again by the nonwoven fabric while moving out of the mat along the covering nonwoven fabric, filtered again by the porous coal ash filled around the mat, and the microorganisms adhered to the coal ash.

In the wastewater treatment method, the membrane separation process for separating substances according to the molecular size was not considered technically important until recently, but when the membrane is used in the process, energy consumption is low, and phase change and high temperature treatment are not accompanied. Due to its advantages, it is recently used for advanced treatment of wastewater.

The membrane separation may be performed using a driving force such as pressure, concentration and potential difference according to the shape and size of the micropores of the membrane, the physical and chemical properties of the membrane, and the shape and size of the membrane separation target material. The membranes used in the current membrane separation process include microfiltration membranes, ultrafiltration membranes, reverse osmosis membranes, gas separation membranes, or pervaporation membranes. ). Since these membranes have limitations on their use depending on their pore size, material, and purpose, the filtration membrane (MF), ultrafiltration membrane (UF), and reverse osmosis membrane (RO) are mainly used for wastewater treatment or sewage treatment. .

In the case of the microfiltration membrane (MF) and the ultrafiltration membrane (UF), since the mechanical strength must be excellent in terms of reliability of the separator system with high water permeability, excellent mechanical strength is required. If the raw water quality is not good when treating industrial wastewater, there is a problem that the membrane is contaminated. And in order to prolong its life, it is required to clean the chemicals to remove impurities at regular time intervals.

Therefore, the life of the membrane is shortened due to membrane fouling, and to prevent membrane fouling, the surface of the membrane should be periodically cleaned, and only raw water in which the particles are removed can be used. It is inadequate for large-scale water treatment of water, river water, seawater, etc. and requires the operation of specialized technicians.

In addition, although there is a method using adsorption, such activated carbon adsorption method has a good ability to remove chromaticity and residual COD, but it is not used well because there is a problem that the need to periodically replace the activated carbon and the cost increases. In addition, such a method can not be expected to be a great effect by using alone, there is a limit that must be used in combination with several other methods.

In addition, most of the wastewater treatment methods described above rely only on artificially constructed treatment processes, which require relatively high installation volume and high mechanical cost of reactors to treat pollutants, resulting in relatively high installation and maintenance costs. . In particular, instability of discharged water quality frequently occurs due to lack of coping capacity when microorganisms are killed in the reaction tank due to changes in inflow flow rate and water quality or air supply equipment failure, and waste sludge is generated a lot. There is a problem of secondary environmental pollution due to ocean dumping.

In order to overcome the shortcomings of these artificial treatment methods, there is an increasing number of cases of soil purification method using natural purification ability. Soil purification method is generally used after placing a contaminant treatment tank at the bottom and covering the top of the reactor with soil. When pollutants enter the soil layer by planting the grass on the soil layer, the pollutant becomes a nutrient of soil organisms so that it is decomposed and removed.

Representative methods applying this natural purification method include HBR method, capillary infiltration trench method, and soil coating type contact oxidation method. HBR method does not directly use soil and microorganisms in soil. After activating the soil microorganisms and circulating them in the reactor to increase the efficiency of nitrogen or phosphorus treatment, this method is relatively high in the maintenance cost of the culture tank and only a few of the advantages of the soil purification method are applied. Do.

The capillary infiltration trench method comprises a sedimentation separation tank, a contact filtration tank, an oxidation infiltration purification tank, and a capillary infiltration trench, among which the precipitation separation tank precipitates solids in the influent, and in the contact filtration tank, organic matter is removed by microorganisms attached to the media. The media at the top of the oxidative infiltration tank is in contact with the soil layer, which supplies the plants growing at the top of the septic tank to supply organic matter, nitrogen, and phosphorus in the septic tank influent, and the pretreated water is the final treatment process. Scattered through the trench's capillary and moved up and down and transversely by the siphon action of the capillary, processed by microorganisms in the soil, then penetrated underground to fill the groundwater, and partly with the nutrition and moisture of the vegetation planted in the upper soil layer. In the way that it is supplied or evaporated to the atmosphere, It does not require any electric power because it flows into the furnace, and it has the advantage of removing nitrogen and phosphorus by soil microorganisms because it penetrates the soil.However, the required site is relatively large compared to other methods and contaminates the soil. Not.

However, in the current maternal infiltration trench method, since waste water is continuously injected, the load is increased, so it is purified by infiltration rather than saturation, that is, infiltration, and the supply of oxygen is reduced, which is likely to cause clogging due to economic problems. Due to the use of porous ores or gravel only in part around the perforated pipe, and the bottom of the remaining portion is using sand, or artificial soil that is not porous, so the waste water moves around the porous ore at first Although it is carried out, there is a critical problem that the purification rate is lowered due to the closing phenomenon as the year is repeated.

Therefore, the present invention has been made in order to solve the problems of the prior art as described above, the object of the present invention is to eco-friendly purification of unsaturated water in the waste water purification apparatus by intermittently sending the waste water to the waste water purification treatment apparatus It is to provide a high-altitude water treatment apparatus and method.

In the lower portion of the inlet port, a plurality of porous distribution holes are installed in the longitudinal direction of the mat so that the introduced treated water flows in the longitudinal direction of the biofilm filtration mat.

The inside of the biofilm filtration mat and the open upper surface are covered with a nonwoven fabric, and the nonwoven fabric extends to both sides in the width direction.

Wastewater, which is fed into the biofilm filter mat and flows in parallel, flows at a moderate speed to both sides by the siphon or capillary phenomenon of the nonwoven fabric, and infiltrates and diffuses into the media layer.

The porous filter layer is filled in the structure around the biofilm filter mat.

Coal ash is used as the porous layer, which is porous and has a large space formed not only on the surface of the media but also inside thereof, which has excellent water permeability, breathability, and water absorption.

The coal ash is subjected to microbial adhesion processing in the porous to form a biofilm.

The outer periphery of the porous water collecting perforated pipe is further wrapped with a nonwoven fabric and sealed to filter the suspended solids and pass only the purified water.

In order to collect the final treated water collected in the plurality of collecting oil pipes again and discharge them along the ramp, the final water collecting pipes connected in the horizontal direction with respect to the water collecting oil pipes are further inclined.

The final collection pipe is connected back to the final collection tank installed outside the structure, whereby the final treated water is discharged to the outside.

The bottom and sidewalls of the structure is further provided with a barrier film that can not pass moisture.

Masato is coated on top of the porous ash layer of coal ash, and grass and other plants are planted on the masato, and soil microorganisms inhabit the roots and surroundings of the planted plants to participate in the removal of nitrogen or phosphorus contained in the wastewater. , Improves the removal rate of phosphorus.

According to another feature of the present invention, the present invention is a high-water treatment method for the first purification treatment of the waste water and then again to the legal discharge criteria and recycled to heavy water, to collect the treated water to the collection pipe by operating a pump And discharging the waste water to the waste water purification apparatus for purifying the treated water by distributing the water to each water supply pipe by the pressure of the treated water collected in the water collection pipe.

In the step of returning the treated water to the wastewater purification treatment device, in consideration of the purification treatment capacity of the wastewater purification treatment device so that the wastewater purification treatment device can be purified so as not to cause clogging, and by using the timer It controls the operation degree and operation time of the pump, and intermittently sends the treated water to the water supply pipe.

It further comprises the step of controlling the amount of water for each water supply pipe by using a control valve installed on one side of the water supply pipe.

By using the water supply indicator installed in each water supply pipe to visually check the water supply for each water supply pipe to control the control valve.

Purifying the treated water includes a step of introducing the treated water branched from the plurality of water pipes into a biofilm filter medium through which an biofilm is formed through the inlet port to adsorb and decompose the treated water. .

The inlet port is provided in plurality in the middle of the biofilm filter mat provided with a long length, to distribute and supply the treated water as a whole.

The inlet port is connected to a porous distribution pipe lengthwise in the longitudinal direction of the biofilm filter mat, the treated water passing through the inlet port is distributed evenly distributed throughout the mat.

The treated water is adsorbed, decomposed, and filtered while moving slowly through a nonwoven fabric that extends in both sides as wings on the inside and the top of the mat by capillary and siphon phenomenon of the nonwoven fabric.

The treated water primarily adsorbed, decomposed and filtered through the nonwoven fabric is again adsorbed, decomposed and filtered through the coal ash porous media layer packed around the mat.

Since the coal ash is porous and has a large space not only on the surface of the media but also inside, it is excellent in permeability, air permeability and water absorption, and maintains an unsaturated state because the air flow and the treated water flow are separated through the space. The process of adsorption, decomposition and filtration of waste water proceeds.

This can be eliminated or prevented.

According to the advanced water treatment apparatus and method according to the present invention having such a configuration, there is an advantage that the advanced water treatment ability is improved by being purified in an unsaturated state.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the advanced water treatment apparatus and method according to the present invention having the configuration as described above will be described in detail.

The wastewater is first purified and then transferred to the wastewater treatment apparatus according to the present invention for recycling to legal discharge criteria and heavy water.

As shown in FIG. 1, the advanced water treatment apparatus according to the present invention includes an automatic water supply apparatus 100 installed in the primary purification treatment apparatus and configured to deliver primary purification treatment water, and waste water purification of the primary purification treatment water. It is composed of a purification apparatus (200).

First, as shown in FIG. 2, the automatic water supply apparatus 100 includes a collecting pipe 110 for collecting the primary purified water and a pump for raising the primary purified water to the collecting pipe 110 ( 120, and a plurality of water supply pipes (130, 132, 134) branched from the water collecting pipe 110 to transfer the primary purified water by the pressure of the water collecting pipe 110, and the water supply pipe 130 And control valves 140, 142 and 144 installed on one side of the water supply pipes 130, 132 and 134 to control the first purified water to determine the amount of water for each water supply pipe 130, 132 and 134, and the water supply pipe ( It is provided on one side of the 130, 132, 134 is composed of a water supply amount display system 150, 152, 154 to display the water supply amount by the scale.

According to an embodiment of the present invention, a timer 160 is attached to the pump 120. The timer 160 is used to arbitrarily adjust the operation and stop time of the pump 120, and to prevent the waste water purification apparatus 200 from being loaded by transmitting a desired amount of water at a desired time. This is because the existing water supply system continuously sends the primary purified water by gravity or the primary purified water is continuously injected by the pump. Therefore, if it is used continuously for a long time, the waste water becomes saturated in the wastewater purification process. Since the infiltration acts by gravity rather than infiltration, there is a problem that the purification function is remarkably deteriorated because anaerobic or clogging occurs due to oxygen deficiency.

Therefore, in the present invention, to maintain the waste water in an unsaturated state, in order to adequately supply the oxygen required for aerobic microorganisms, the amount of water and the time of the first purified water is properly adjusted so that the waste water can be purified while maintaining an unsaturated state. It has its features.

In addition, a plurality of water supply pipes 130, 132, 134 is installed as the first pipe 130, the second pipe 132 and the third pipe 134 as shown in FIG. It performs the function of equally distributing the amount of water for each of the pipes (130, 132, 134), and the amount of water for each of the pipes (130, 132, 134) through the above-described control valve (140, 142, 144) To control. The water pipes (130, 132, 134) are connected to the biofilm filter mat (220, 230, 240) to be described later.

Through the water level indicators 150, 152 and 154, it is possible to directly check the amount of water for each water supply pipe 130, 132, 134. As described above, according to the automatic water supply apparatus 100 according to the present invention, the throughput and load that can be purified by the wastewater purification apparatus 200 are converted into data to calculate the daily purification treatment capacity in advance, and the expected throughput and load are considered. By operating the timer 160 and checking whether the water is being processed by the timer 160 through the water level indicators 150, 152 and 154, so that the waste water infiltrates into the unsaturated state in the wastewater purification apparatus 200. Be sure to

The structure 210 of a predetermined space is required for the wastewater purification treatment of the present invention. The structure 210 can be used anywhere if there is a notice that is not used, such as ground or rooftop, depending on the site conditions.

" 형상을 하게 된다. 상기 생물막 여과매트(220, 230, 240)는 차수막 통공구조로 되어 있어, 유입된 오폐수가 전체 매트(220, 230, 240) 안으로 평행하게 유입된다.As shown in FIG. 3, the wastewater purification treatment apparatus 200 according to the present invention has a biofilm filter mat 220, 230, and 240 having a rectangular structure 210 having a rectangular adsorptive decomposition of wastewater to form a biofilm. Are installed in multiple directions. The biofilm filtration mats 220, 230, and 240 are cross-sections of which are open at the top, and the bottom and both sides are closed.

The biofilm filtration mats 220, 230, and 240 are formed in the water-permeable membrane through-holes so that the introduced waste water flows in parallel into the entire mats 220, 230, and 240.

As shown in FIG. 4, the water is fed in the middle of each of the filter mats 220, 230, and 240 so as to supply the first purified water uniformly in the longitudinal direction of the biofilm filter mats 220, 230, and 240. A plurality of inlet ports 222, 222 ′ 232, 232 ′ 242, 242 ′ connected to the pipes 130, 132, 134 are installed. Accordingly, the mall water supply pipes 130, 132, and 134 may be branched again by the number of the inflow ports 222, 222 ', 232, 232', 242, 242 '.

The inflow ports 222, 222 ′, 232, 232 ′, 242, 242 ′ are porous to allow wastewater introduced into the bottom to flow in the longitudinal direction of the biofilm filter mat 220, 230, 240. Dispensing perforated pipes 224, 224 ′ (234, 234 ′) 244, 244 ′ are installed along the lengthwise direction of the filter mats 220, 230, 240.

As shown in FIGS. 4 and 5, non-woven fabrics 226, 236, and 246 are covered with the inside of the biofilm filtration mats 220, 230, and 240, and particularly, the non-woven fabrics 226, 236, and 246. ) Wings are flanked on both sides. Therefore, the wastewater that has passed through the biofilm filter mats 220, 230, and 240 is filled with porous materials filled with the nonwoven fabrics 226, 236, and 246 while moving at a moderate speed to both sides by a siphon phenomenon or a capillary phenomenon of the nonwoven fabric. Infiltrate and diffuse into the media and move.

On the other hand, the coal ash porous media layer 250 is filled around the biofilm filter mat (220, 230, 240). The coal ash is a porous material that is excellent in permeability, breathability, and water absorption. The coal ash is multiplied by using organic matter of wastewater introduced by symbiotic coexistence between adherent microorganisms and soil microorganisms as a substrate, and extensively decomposes, oxidizes, and recycles organic matter of wastewater. It has the function of adsorption and filtration and is used as a habitat for microorganisms. Therefore, compared with the conventionally used for waste water purification treatment, crushed stone, black soil, sand, activated carbon, porous foam urethane, the price is cheaper and the purification effect is more excellent.

In addition, the porous porous coal ash has a useful composite microorganism having excellent organic matter decomposing ability, and is adsorbed and decomposed while the wastewater passes through the inner filter layer 250, and the specific surface area of the microorganism is high, thereby increasing the purification treatment effect.

Therefore, the useful composite microorganisms are adhered to the porous porous coal ash, whereby the specific surface area of the microorganisms is large, and the formation of the biofilm is improved. That is, in the media layer of the present invention, there is a space for attaching and processing microorganisms in the interior of the media, so that the formation of the biofilm in the media is easy.

As such, an infinite space is formed not only on the surface of the media but also on the media, thereby minimizing sludge generation because endogenous respiration, anaerobic metabolism and extensive predatory activity can be sustained for a long time.

According to an embodiment of the present invention, when the influent BOD criterion is 100 ppm / L or less, when only 1 ton of wastewater is treated, only 10 tons of coal ash are sufficient.

At least one check hole (228, 238, 248) is installed on the upper part of the biofilm filtration mat (220, 230, 240) to check whether the wastewater introduced from the automatic water supply (100) is purified without clogging. Preferably, it is installed on both ends of each biofilm filter mat (220, 230, 240) is possible to check for each mat. The inspection openings 228, 238, and 248 are vertically installed on the biofilm filter mats 220, 230, and 240, and the upper side thereof communicates with the upper portion of the Masato 290 coating layer, which will be described later, and is exposed to the air. Although not shown, the retractable cover can be detachable.

For example, if an excessive load is generated in the wastewater purification apparatus 200 due to an inexperienced operation of the manager, the wastewater introduced into the wastewater purification apparatus 200 is blocked by the biofilm filtration mats 220, 230, and 240, and the degree of water drainage is increased. Deterioration, in this case, the administrator can check this through the check ports (228, 238, 248). When such a closing phenomenon is confirmed, the groundwater or the like is introduced through the check holes 228, 238, and 248 to be washed, thereby removing or preventing the blockage.

The lower portion of the structure 210 is provided with a plurality of porous collecting and collecting pipes 260 in the longitudinal direction for collecting and discharging the final treated water. A nonwoven fabric is enclosed and enclosed on the outer side of the collecting oil pipe 260, and the floating material is filtered through the nonwoven fabric to discharge only clean water. This is to prevent the coal ash of the coal ash porous media layer 250 is mixed with the treated water and discharged.

In order to collect and discharge the final treated water collected in the plurality of collecting hole 260 to one place again, the final collecting pipe 270 is installed to be inclined in the horizontal direction with respect to the collecting hole 260. The final collection pipe 270 is connected back to the final collection tank 300 installed outside the structure, so that the final treated water is discharged to the outside.

On the bottom of the structure 210, a water barrier film 280 is not provided that can pass through. The order film 280 blocks the waste water or the final treated water from leaking out of the structure 210.

The upper portion of the coal ash porous media layer 250 is coated with Masato 290 to plant grass and the like. Around the roots of the planted grass and other plants inhabit a large amount of soil microorganisms are involved in the removal of nitrogen or phosphorus contained in the waste water to improve the nitrogen, phosphorus removal rate.

Hereinafter, the operation of the advanced water treatment apparatus and method according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

The waste water purified first is sent to the waste water purification apparatus 200 via the automatic water transmission device 100 for purification.

First, the primary purification treatment water is introduced into the collection pipe 110 by the pump 120. The treated water collected in the collecting pipe 110 is distributed to each of the water supply pipes 130, 132, and 134 by the pressure of the collecting pipe 110, and is pumped to the waste water purification treatment device 200.

At this time, the waste water purification treatment apparatus 200 calculates the capacity to purify without clogging and operates the timer 160 accordingly, according to the purification treatment conditions of each biofilm filtration mat (220, 230, 240) By operating the control valve (140, 142, 144) to adjust the amount of water and the speed of the waste water. In addition, it is possible to visually check the degree of water transmission through the water level indicator 150, 152, 154.

In this way, in order to control the amount and speed of the water supply, the timer 160, the control valves (140, 142, 144) and the water level indicator 150, 152, 154 to check the amount of water is set and the intermittent water system By adopting this method, the load is minimized in the wastewater purification treatment apparatus 200, the wastewater is infiltrated in an unsaturated state, and the closing phenomenon is prevented. Natural cleansing capacity is increased, and the cleansing capacity is not lost even after repeated use for a long time.

Primary treatment water distributed to the water supply pipes (130, 132, 134) is introduced into the biofilm filter mat (220, 230, 240) through the inlet ports (222, 232, 242), the inlet ports (222, 232) , 242 are evenly distributed over the entire length of the biofilm filtration mats 220, 230, and 240 through the distribution hole pipes 224, 234, and 244 connected to the inflow ports 222, 232, and 242. Is distributed.

The biofilm is formed in the biofilm filtration mats 220, 230, and 240, and the introduced wastewater is primarily adsorbed, decomposed, and filtered. In addition, since the nonwoven fabrics 226, 236, and 246 are extended on both sides of the mats 220, 230, and 240 so as to extend along the sides of the wings, the waste water remaining after the first adsorption, decomposition, and filtration is filtered through the nonwoven fabric. While moving out of the mat (220, 230, 240) is filtered again by the rise of the capillary and siphon phenomenon of the nonwoven fabric. In this way, when the waste water is filtered through the nonwoven fabric, the waste water moves at a gentle speed, so that the adsorption, decomposition and filtration actions are improved.

If the nonwoven fabric of the inner part of the mat and the wing portion of the upper portion of the mat is not continuously connected, the siphon phenomenon does not occur. If there is only the nonwoven fabric at the upper portion, the water and the nonwoven fabric do not contact when the water is less, the siphon phenomenon occurs. You will not.

The treated water filtered through the nonwoven fabrics 226, 236, and 246 is again diffused and infiltrated through the coal ash porous media layer 250 filled in the structure 210, and maintains an unsaturated state while raising and lowering the capillary again. Adsorption, decomposition and filtration.

Since the filter layer 250 is made of porous ash which is excellent in permeability, breathability and absorption, the flow of air and the flow of waste water are separated from the coal ash. In other words,

In the related art, as shown in FIG. 6, waste water and air communicate with each other through the same flow path between solid particles, and the flow of air is stopped during watering and infiltration, and sufficient air is not supplied to the lower part of the media, resulting in a blockage phenomenon. Excessive biofilm was formed between the solid particles to cause biofilm desorption. However, according to the present invention, as shown in FIG. 7, waste water flows through the inside of the medium, and air is passed through the medium to provide sufficient oxygen to the bottom of the medium. The supply is made so that no closing or detachment occurs.

Accordingly, air in the atmosphere, dissolved oxygen of the treated water, and the like are supplied, and the purification process by the microaerobic organism can be performed to the deep layer of the filter medium 250. In addition, the porous porous coal ash can be treated with useful complex microorganisms such as bacteria having excellent decomposition ability of organic wastewater, thereby improving the treatment capacity of the wastewater and improving the biofilm formation due to the large specific surface area of the microorganisms.

The wastewater is adsorbed, decomposed and filtered while passing through the coal ash porous filter layer 250 to be cleansed, collected in a collecting oil hole 260 installed under the structure 210, and then sent to the final collecting pipe 270. At this time, since the nonwoven fabric is wrapped around the water collecting hole 260, the floating material such as the fine media of the media layer 250 is filtered.

At this time, when the waste water is purified and reaches the bottom, the floating material is almost in a state, but due to the nonwoven fabric wrapped in the bottom collecting oil pipe 260, the filter ash of coal ash is not included in the treated water. It is preferable to use special materials with pores smaller than the particle size of. The treated water collected in the final collection pipe 270 is discharged to the outside through the tank 300 that functions as a discharge water check tank.

Incorrectly controlling the standards of influent wastewater, the amount of water and the rate of water supply, and when there are signs of clogging and clogging of the wastewater in the biofilm filtration mats (220, 230, 240) and the filled media layers, the check holes (228, 238, 248). ) You can check the degree of water blockage by putting groundwater and seeing the water drainage. At this time, by blocking the ground water and the like through the check holes (228, 238, 248), it is possible to eliminate the clogging phenomenon.

Since the Masato 290 is coated on the upper layer of the structure 210 and the grass is planted, nitrogen or phosphorus contained in the waste water is removed even by soil microorganisms inhabiting the roots of the planted grass.

As described above, the present invention, unlike the gravel or sand by using a media such as porous coal ash, such as porous coal ash, infinite space is formed not only on the surface of the media but also to enhance the air circulation, It can be seen that the technical idea is to construct the microorganisms by tackifying a wide range of microorganisms between spaces and to minimize the occurrence of sludge through endogenous respiration and anaerobic metabolism. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.

As described above, according to the configuration of the present invention, the following effects can be expected.

First, to provide an advanced water treatment apparatus and method for purifying in the unsaturated state in the wastewater purification treatment apparatus by intermittently sending the primary treated water to the wastewater purification treatment apparatus using a timer.

Second, by installing the nonwoven fabric on the biofilm mat is expected to take advantage of the siphon phenomenon and capillary phenomenon to maximize the treatment water while moving the treatment water at a gentle speed.

Third, by filling the permeability, air permeability and permeability of natural material porous media around the perforated pipes, it is a media that separates the flow of treated water from the flow of air, so that the process of adsorption, decomposition and filtration of waste water while maintaining an unsaturated state This occurs, the blockage phenomenon is suppressed, the effect of improving the decomposition and purification ability of the waste water is expected.

Fourth, it is expected to be economical by minimizing environmental pollution by recycling coal ash which is industrial waste as a porous media.

Fifth, by sticking microorganisms to porous coal ash, the effect of decomposition, oxidation, adsorption, and filtration of organic matter contained in wastewater is increased and waste sludge is minimized.
