The present invention relates to a method and apparatus for purifying miscellaneous wastewater using artificial wetlands, and more particularly, to a method and apparatus for supplying and purifying miscellaneous wastewater discharged from a kitchen or a bathroom to provide water for use in a hydrophilic environment.

There is increasing interest in the installation of aquatic facilities in complexes, residential land development districts, residential environment improvement projects and urban redevelopment districts to improve the quality of life. However, there is a lack of technology to secure economic and sustainability for the supply of high quality water resources, which is a key factor in the establishment of hydrophilic facilities, and to continuously manage water quality.

When creating a hydrophilic environment, it is necessary to secure economic feasibility (maintenance management, water price), supply water resources continuously, and water quality management methods and technologies. In other words, a low-energy method that can be easily managed in a living space and maintained at low cost is required.

Hydrophilic facilities in residential complexes require abundant water and high-quality water sources, and most of them use groundwater or tap water, but there are problems such as economic feasibility and securing water quality and water quality. Therefore, it is necessary to develop a low-energy type application method considering the maintainability, economic feasibility, water quality, and water quality when creating a hydrophilic environment.

The main technology in the construction of hydrophilic space is applied with natural purification method. Natural purification method is a technology to treat wastewater and sewage using physicochemical and biological reactions by interaction between water, gravel and soil, plants, microorganisms and atmosphere in the natural state, artificial wetland method, soil utilization method, land treatment method, aquatic life It is divided into plant-use process.

In particular, wetlands are generally saturated with water throughout the year or for a certain period of time. The wetland is a system that plants vegetation such as high temperatures, ropes, buds, babies, reeds, irises and ropes. Have

However, the conventional artificial wetland having the above advantages is a situation that is used for the primary sewage treatment only in a limited area, such as rural areas because of the large size constraints.

In addition, the treated water cannot be reused due to inferior treatment efficiency, or only a relatively small amount is used compared to the throughput, and there is a problem that odors or mosquitoes occur in the free surface artificial wetland. The subsurface artificial wetland, which was created to do so, often loses its function due to occlusion.

An object of the present invention for solving the above problems is to provide a wastewater purification method and apparatus to reduce the maintenance cost of a hydrophilic facility by providing the water resources used in the construction of a hydrophilic environment to purify the wastewater, not water supply or groundwater.

Another object of the present invention is to provide a wastewater purification method and apparatus in which low energy is used to produce water resources supplied to a hydrophilic environment facility by using artificial wetlands.

It is another object of the present invention to provide a method and apparatus for purifying wastewater that overcomes the disadvantages of usability due to the limitation of the installation area of the conventional artificial wetland by using the artificial wetland less installation area.

Another object of the present invention is to maximize the treatment efficiency of treated water in the use of artificial wetlands, to solve problems such as odors and mosquitoes, and to block the phenomenon of artificial wetlands of subsurface flow made to solve these problems. The present invention provides a method and apparatus for treating wastewater that does not occur.

In the present invention to achieve the object as described above and to perform the problem for removing the conventional defects in the method of purifying the artificial wetland,

One of the inlet, the stop and the outlet part is provided with an artificial wetland in which the inlet part filled with coarse water is filled with coarse zeolite, the stop part filled with soybeans, and the outlet part filled with coarse zeolite is sequentially formed. At one of the aerobic and anaerobic conditions to occur, characterized in that the method of purifying by removing organic matter, nitrogen and phosphorus in the wastewater.

Gray water is generally referred to as kitchen and bathroom drainage except toilet and laundry drainage. Such drainage can be selectively used in the apartment complex, residential complex, building, etc., each drain pipe is installed.

In the above, aerobic conditions occur from the inlet to the stop when the inlet is aerated.

In the above organic matter, when the inlet is aerated, the removal rate is high at the initial stage, but it is removed by the microorganism as a whole at the stop and the outlet.

In the inlet, a thick zeolite adsorbs ammonium contained in a mixed wastewater to remove nitrogen first, thereby delaying the occurrence of occlusion using soybean gravel at the stop part after the first removal of nitrogen. It is characterized in that the microorganisms are attached to the soybeans, which are treated biologically, and at the same time, the phosphate containing phosphorus in the mixed wastewater is combined with the iron ions generated by the sulfate reduction to precipitate and remove under anaerobic conditions.

In the above, biological treatment refers to the removal of contaminants by microorganisms, and chemical treatment is excluded.

After the phosphorus is removed from the stop portion, the coarse zeolite in the outlet portion is treated with ammonium ions that have not been removed due to the lack of organic matter to treat the nitrogen secondary.

When explaining the method according to another embodiment, only 70-80% of the ammonium occupying most of the total nitrogen in the mixed wastewater introduced by intermittent aeration in the inlet is nitrified by intermittent aeration, the rest is adsorbed by coarse zeolite It is characterized by a method of activating microorganisms by aeration to remove some phosphorus in the early stages.

In the above removal of phosphorus, the initial removal rate is high due to the activity of the microorganism due to aeration at the beginning of the inlet, but the mechanism of phosphorus removal occurs in the stop and the outlet.

After nitrification according to the intermittent aeration, ammonium adsorption by Zeolite and removal of some phosphorus, delay the occurrence of occlusion phenomenon by using soybean gravel at the stop, biological treatment by attaching microorganisms to soybean gravel It is configured to provide the organic materials necessary for nitrification and denitrification.

After introducing the raw water in the stop portion, the iron ions generated by denitrification and sulfate reduction in the artificial wetland changed to anaerobic conditions in the outlet portion is configured to combine with phosphate to precipitate and remove phosphorus.

The phosphorus of the raw water provided again above is precipitated out under anaerobic conditions and the ammonium nitrogen is adsorbed by the trailing zeolite.

The artificial wetland is composed of a natural oil drop using a high and low step.

Solvent mosquitoes and odors by flowing the inflow water level flowing into the artificial wetland below the filling height of the zeolite and coarse gravel as media, while the artificial wetland has aerobic and anaerobic conditions, and the organic matter and phosphorus in the wastewater passing through , To remove nitrogen, coarse zeolite, coarse gravel. Occlusion was prevented by using soybeans.

That is, the artificial wetlands of the present invention have aerobic and anaerobic conditions, as described above, so that aerobic and anaerobic conditions appear in one artificial wetland through the intermittent aeration of the inlet and the consumption of DO due to biological treatment, and the inflow of raw water from the middle part. do.

The artificial wetland is configured to adjust the treatment period according to the pollution load by setting the HRT (hydraulic retention time) per surface area of 1.3 m ² to 2 to 6 days.

The reason for limiting the numerical value is that when the surface area is 1.3m ² as the unit surface, it is difficult to secure a sufficient removal rate when the HRT is 2 days or less, and the treatment efficiency is lowered after 6 days.

The soybeans are configured to give a sufficient margin for the blockage of artificial wetlands using a density of 2.4 ~ 2.7g / cm ³ or more, effective particle diameter 5mm, the range of particle diameter 5-7mm, porosity 35-40%.

The reason for the limitation as described above is that occlusion does not occur when the limited numerical condition is satisfied. In particular, if the particle size is smaller than the limited particle size, the probability of occlusion increases, and when the particle size increases, adsorption by filtration media (such as soybean gravel), filtration, and microorganism adhesion ability are lowered.

In addition, the reason for limiting the density and porosity is to affect the occlusion phenomenon and microbial adhesion depending on the particle size of soybean, first determine the particle size and then the effective particle size and the range of particle size (measured according to KS F 2502), density and porosity (KS Measurement according to F 2504) to define the optimum value according to the invention.

The coarse zeolite has a density of 1.68 to 1.74 g / cm ³ , an effective particle diameter of 15 mm, and a particle diameter of 15 to 25 mm having a porosity of 40 to 46% to 15% of the total volume. The reason for this limitation is that the function of zeolite is the selective adsorption of ammonium, and the reason for limiting the volume to 15% is to take into account the characteristics of mixed wastewater; This is to facilitate the inflow and outflow of raw water.

In addition, the reason for the limitation of density and the porosity is to influence the blockage phenomenon, microbial adhesion, and ammonium adsorption depending on the particle size of coarse zeolite, and then to determine the particle size and the effective particle size and range of particle size (measured according to KS F 2502), density and After measuring the porosity (measured according to KS F 2504), the optimum value according to the invention is defined.

It further comprises a UV sterilization step to remove the harmful bacteria in the human body contained in the treated water treated through the outflow.

The method may further include supplying the treated water treated in the artificial wetland to a hydrophilic facility.

The plant is planted in the upper portion of the middle portion. Plants are plants such as strings, mussels, yellow irises, reeds, buds, and babies.

The thick zeolite of the inlet and outlet is configured to be separated and detached, and to be replaced with each other according to use.

The intermittent aeration is configured to operate for 2 to 6 hours aeration, 6 to 10 hours aeration. The reason for this limitation is to obtain the optimum treatment efficiency using low energy as much as possible, and the degree of pollution load of the influent water (assuming that the sewage is CODcr 50 ~ 400mg / l, TN 5 ~ 40mg / l, TP 1 ~ 10mg / l). Change the elasticity according to the appearance) to limit the time to achieve the initial removal rate and nitrification as necessary.

If the intermittent aeration time is increased by more than 4 hours to increase the nitrification rate of ammonium, coarse gravel (density, porosity equal to soybean gravel, particle size 3 ~ 7cm) can be used instead of coarse zeolite.

The miscellaneous waste water supply flows into the storage tank from the kitchen drainage pipe or the bathroom drainage pipe, etc., and the raw water flows into the artificial wetland by adjusting the flow rate with a pump, and other raw water flows back to the existing sewage pipe through the monthly flow. Steps.

In another aspect, the present invention is a device for performing the above-described method, the wastewater supply means, the inlet is filled with thick zeolite; A stop portion filled with soybeans connected to the inlet portion; And the outlet portion is filled with a thick zeolite connected to the stop portion; is characterized in that it consists of artificial wetland equipped with a natural flow type using a high-level step in order to purify.

The apparatus of the invention also comprises means for aeration of the inlet; It further comprises a means for supplying the waste water to the stop.

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

Figure 1 is a schematic diagram according to an embodiment showing the configuration of the artificial wetlands according to the invention, Figure 2 shows a schematic diagram according to another embodiment showing the configuration of the artificial wetland according to the present invention, as shown Artificial wetland has removal characteristics for nitrogen and phosphorus by using environmentally friendly media such as thick zeolite and soybean.

Artificial wetland of the present invention having such characteristics has two embodiments according to FIGS. 1 and 2, each of which can be operated independently.

First, the configuration according to the embodiment of FIG. 1 will be described. The artificial wetland of the present invention is treated with a multi-stage structure consisting of an inlet part 1, a stop part 2, and an outlet part 3, and is supplied to a hydrophilic environment. It has a structure to produce water resources.

Specifically, the inlet section 1 by installing a thick Zeolite and to smooth the inflow of waste water from miscellaneous sources (Greywater), at the same time as a bunched a total nitrogen of the raw water containing mostly ammonium form of the most thick Zeolite which selectively adsorbs the ammonium Configure to remove nitrogen.

The stop part 2 is configured to delay the occurrence of occlusion phenomenon by using soybean gravel and to allow biological treatment by attaching microorganisms. In addition, since the stop part is an anaerobic condition as a whole, phosphorus is precipitated and removed by binding iron ions generated by sulphate reduction with phosphate.

The reason why the interruption is anaerobic is because the enemy is anaerobic and thus does not aeration and the anaerobic conditions do not change.

The thick zeolite installed in the outlet part 3 is installed for smooth flow of the effluent through the stop part, and is configured to reprocess ammonium ions that have not been removed due to lack of organic matter.

In addition, the artificial wetland of the present invention according to the embodiment of Figure 2 is a basic structure of the hydrophilic water treatment through the multi-stage structure consisting of the inlet portion 1, the stop portion 2 and the outlet portion 3 as shown in FIG. It has a structure that produces water resources to be supplied to the environment.

Specifically, the inlet part is provided with a thick zeolite to facilitate the inflow of mixed water (Greywater), and at the same time it is configured to allow the intermittent aeration, nitrification is possible, 70-80% of the ammonium occupying most of the total nitrogen of the inlet water Only the degree was nitrified by intermittent aeration and the rest was adsorbed by coarse zeolite to increase the duration of adsorption capacity of zeolite. In addition, the aeration caused the activity of the microorganisms to improve the initial phosphorus removal ability.

The stop portion was configured to delay the occurrence of the occlusion phenomenon by using soybean gravel and to allow microorganisms to be attached so that biological treatment is possible and at the same time the raw water is introduced to provide the organic material necessary for nitrification and denitrification.

The outflow portion was configured such that iron ions generated by denitrification and sulfate reduction were combined with phosphates in the artificial wetlands changed to anaerobic conditions to precipitate and remove phosphorus.

1 and 2 in accordance with the different embodiments the plant vegetation is possible, especially vegetation, such as reeds, yellow irises, strings, large high lather is possible. These plants have advantages in water treatment and ecological environment creation.

In addition, the inlet, the stop, and the outlet of the present invention may solve the problem of mosquitoes and odors by selecting the subsurface flow, and at the same time, it may delay the occurrence of occlusion by using a medium having a relatively large gap.

The artificial wetland of the present invention can be treated in a natural flow method, HRT per 1.3m ² surface area is polluted between 2 to 6 days or fluidly treated (Greywater) according to the throughput.

The treated effluent can also be UV sterilized by installing a reservoir before entering the hydrophilic facility, which constitutes the final stage of treatment.

Effluent water that can be disinfected by aeration or sunlight in a hydrophilic facility is generated, but when UV disinfection is required separately, high turbidity hinders the disinfection effect. This artificial wetland effluent shows 1.3 NTU, which makes turbidity easy for UV disinfection. .

In addition, the inlet and the outlet of the thick zeolite was configured to be detachable detachment, by this configuration, in the case of the embodiment according to Figure 1 in the inlet takes a lot of contaminant load, the artificial wetland of the present invention has the same front and rear end configuration It is easy to replace the inlet part with the front and rear part, so that the pollutant load can be distributed in one place.

In addition, in the embodiment according to FIG. 2, the thick zeolite of the inlet which takes a lot of contaminant loads is designed to be separated and detached so that it can be replaced with the outlet of the new coarse zeolite that exchanges or takes less contaminant loads.

The artificial wetland of the present invention configured as described above is simplified, unlike the existing wetland system, which takes up a complicated and large area, and reduces the required site by selectively treating only the greywater. Therefore, it is possible to install in the apartment underground space. There is no need for space, so it will be possible to install in urban areas where it is difficult to secure new space.

Figure 3 shows a schematic diagram showing a configuration for supplying the mixed water to the artificial wetland of the present invention, as shown in Figure 1 and 2, the mixed water supplied to the supply.

Specifically, the sewage discharged from the apartment complex is divided into toilet drainage (Blackwater-sewage), kitchen and bathroom drainage (Greywater-drainage drainage) .Greywater has a relatively low pollution load, which is advantageous for reuse. The bathroom drainage, kitchen drainage, and bathroom drainage pipes are divided in the basement of the housing complex, so there is no difficulty in collecting only the gray water, and the underground space is secured, so there is no need to secure a new space to install the artificial wetland. Can be installed in urban areas.

The method of collecting such greywater in the artificial wetland device of the present invention is introduced into the storage tank from the existing kitchen drainage pipe and the bathroom drainage pipe, and the raw water that is not constantly introduced flows into the artificial wetland by adjusting the flow rate with a pump. In addition, other raw water is configured to flow back to the existing sewage pipe through the monthly flow.

In the present invention, the artificial wetlands according to FIGS. 1 to 3 have been operated for a long time (over 40 months of continuous operation). Despite the long-term operation, the adsorption of microorganisms such as zeolite and soybean, filtration adsorption, microbial activity and intermittent aeration (4-hour aeration, 8-hour aeration) continue to show high removal rates for contaminants.

The COD is removed from the initial inlet part, and many organic matters are removed during the nitrification by filtration, adsorption, and aeration.

Therefore, Greywater is additionally introduced at the stop so that denitrification can occur at the outflow part.In addition to the organic material necessary for denitrification, the remaining organic matter is removed by filtration, adsorption, and microbial activity of the media, and DO is also consumed to create an anaerobic state. It is almost removed from the outlet and the outflow shows satisfactory water quality. The CODcr shows a removal rate of 90% or more, and satisfies the standard of the wastewater quality standard CODmn 20 mg / l or less.

Nitrogen nitrate is rarely denitrified due to aerobic conditions and lack of organic matter to the middle part, but the organic matter is supplemented by raw water introduced into the middle part, and the DO consumption and low DO concentration of microorganisms through the removal of initial contaminants ( 0 to 0.1 mg / l) of raw water is introduced into the anaerobic condition, which leads to denitrification. At this time, the ammonium not removed is adsorbed through the thick zeolite section of the outlet. The removal rate of TN 71-97% is shown, and the concentration of the effluent shows a good water quality of 0.1-2.8 mg / l.

Figure 7 is a graph showing the change in TP concentration and removal rate according to the installation of the artificial wetland of the present invention, as shown in the phosphorus represents a removal rate of 50 ~ 83%, the concentration of the effluent represents 0.13 ~ 0.58mg / l. Phosphorus is removed by the active activity of microorganisms due to the initial aeration, and the raw water introduced after the interruption is removed by binding precipitated by iron ions generated in the gravel as sulfate is reduced in the anaerobic state.

8 is a graph showing the turbidity change according to the installation of the artificial wetland of the present invention, as shown, the turbidity of the influent is 7 ~ 50NTU and removed by the filter medium under the influence of filtration, adsorption and precipitation, microorganisms, etc. The turbidity is 1.3 NTU, which satisfies the water quality standards of the mixed water.
