On the other hand, the amount of water required in industrial sites and living places is rapidly increasing, and there is an urgent need for a method of appropriately treating wastewater such as discharged sewage and sewage and recycling it.

Conventionally, treatment methods and devices for improving the water quality are also called waste water treatment systems or sewage treatment systems, and their function is to purify domestic wastewater, factory water and livestock wastewater. It is to be discharged to the stream or recycled again.

Known representative wastewater treatment processes are known as activated sludge treatment. The process is a representative biological treatment method of activated sludge (a sludge that aerated and sedimented by sewage to aerated water, and abiotic bacteria, protozoa, worms, etc., which reproduce organic matter as a nutrient source, and abiotic organisms such as organic and inorganic). Aggregate of sludge) and sewage are mixed and aerated and stirred in an aeration tank to adsorb colloid and soluble organic matter to activated sludge to facilitate precipitation formation.

However, the process is primarily aimed at removing organics and is not suitable for nitrogen and phosphorus removal. To solve this problem, the Bardenpho process (two anoxic and two aerobic tanks), the A / O process (removing hydrocarbons and phosphorus using two reactors) and the A ² / O process (nitrogen and phosphorus simultaneously) Treatment), sequencing batch reactor (SBR), and the like.

Meanwhile, in the field of wastewater treatment, technology has been improved in consideration of increased treatment efficiency, space utilization, process simplification, and operation cost reduction.

Thus, for example, it is possible to fundamentally block water pollution by completely treating sewage / wastewater generated in a facility located independently in a clean area and recycling it to heavy water and drinking water / drinking water.

Hereinafter, the present invention can be achieved by the following description with reference to the accompanying drawings. The following description is to be understood as describing preferred embodiments of the invention, but the invention is not necessarily limited thereto.

1 is a process diagram schematically showing a wastewater (sewage) treatment process according to an embodiment of the present invention.

The treatment process according to the present invention is not particularly limited and various industrial wastewater and / or domestic sewage can be treated as raw water.

In the drawing, the raw water is transferred to the membrane bioreactor using zeolite. The membrane bioreactor is disclosed in Korean Patent Application No. 2005-68837 of Applicant of the present invention, and the prior art discloses the present invention. It is included as a reference.

At this time, it is optionally subjected to an equalization tank (1) and the screen separator (2). The equalization tank can increase the efficiency of the subsequent process by absorbing and equalizing the fluctuations in the flow rate and the water quality of the influent wastewater, and preferably, two or more tanks are used. Screen separators can remove relatively large solids suspended in water during water treatment using screens (preferably having an average diameter of about 0.5 to 50 mm) such as wire mesh and steel grids. The screen may be composed of bar rods, wires, grants, wire meshes, perforated plates, and the like.

The sewage having passed through the screen 2 is transferred to the anoxic bath 4 together with the zeolite powder and treated without oxygen supply, and in some cases, it is preferable to treat it under stirring. In the oxygen-free tank (4), the zeolite powder moves along with the flow of the waste water, and the ammonia nitrogen (NH ₄ ⁺ -N) contained in the raw water is ion-exchanged with cations such as Na ⁺ of the zeolite to remove nitrogen from the waste water. do. At this time, the temperature of the oxygen-free tank is not particularly limited, but is preferably about 5 ℃ to 35 ℃, dissolved oxygen (DO) in the oxygen free tank (DO) is preferably about 0.2mg / L or less.

At this time, both natural or synthetic zeolites may be used as the zeolite powder to be injected into the oxygen-free tank 2, and as long as it enables the above-described ion exchange reaction, it is not limited to a particular kind. In addition, the input amount of the zeolite powder is determined according to the concentration of ammonia nitrogen contained in the wastewater flowing into the anoxic tank (2), the method of determining the input amount of the zeolite is disclosed in the applicant's domestic patent application No. 2005-68837 It is. According to a typical aspect of the present invention, the zeolite powder has a pore size of about 30-100 nm, and a specific surface area of about 80-100 m ² / g.

The denitrified sewage discharged from the anoxic tank 2 is introduced into the membrane separation tank 5 so that solid-liquid separation is performed through a separation membrane (installed at least one) installed therein. At this time, the zeolite powder and sludge (solid) do not pass through the separation membrane, the solids are separated and the remaining raw water is transferred to the next step. Preferably, a discharge pump (not shown) is connected with the separator to facilitate transport.

On the other hand, the ion-exchanged zeolite powder and sludge (solid) remaining on the surface of the membrane in the membrane separation tank 5 is discharged in the form of sludge from the membrane separation tank 5, for this purpose, the membrane separation tank ( Aeration using an aeration device (not shown) located at the bottom of 5) facilitates separation from the separator.

Further, according to the above embodiment, it is preferable that about 95% to 98% of the zeolite powder and sludge discharged from the membrane separation tank is returned to the aeration tank 3. At this time, a conveying pump (not shown) is connected with the membrane separation tank 5 to facilitate conveying. The excess sludge not returned is preferably concentrated in the sludge storage tank 6, then the concentrate is treated separately (e.g. consignment treatment) and the residue is transferred back to the equalization tank 1.

The aerobic tank 3 is a nitrification reactor, which regenerates zeolite powder ion-exchanged by nitrifying microorganisms. Specifically, the zeolite conveyed with the sludge continuously converts ammonia nitrogen to nitrate nitrogen (NO ₃ -N) in solution as the equilibrium of ammonia nitrogen ions is broken by nitrification. In this way, the discharge of the aerobic tank (especially the regenerated zeolite), together with the fresh water flowing through the new zeolite and the screen, is transferred to the oxygen-free tank 4, thereby reducing the input amount of the new zeolite. The temperature of the aerobic tank is not particularly limited, but is preferably about 5 to 35 ° C., and the amount of dissolved oxygen (DO) in the aerobic tank is preferably about 1 mg / L or more.

On the other hand, in the present invention, it is preferable that the liquid flow discharged from the membrane separation tank 5 of the membrane bioreaction part satisfies the water quality standards of Table 1 below, and the process conditions of the membrane bioreaction part described above are appropriately for this purpose. Can be adjusted. The discharged liquid stream is then subjected to an advanced processing step.

On the other hand, prior to the advanced treatment step, the liquid flow is passed through the primary treatment tank (7), and a portion of the treated water in the primary treatment tank (7) is transferred to the membrane separation tank to remove the zeolite powder and sludge from the separation membrane as backwash water It can also be used to separate (see dashed line in Figure 1).

In the advanced treatment step, the liquid flow sent from the primary treatment tank 7 is first treated by ozone generated from the ozone generator 11 in the ozone reactor 8. Ozone treatment can achieve effects such as sterilization of bacteria and viruses in solution, decomposition of organic coloring components, decomposition of odorous substances, reduction of COD, and decomposition of toxic components. In addition, it is effective as a pretreatment for a subsequent first activated carbon filtration step because it has the effect of removing ammonia nitrogen and dissolved organics.

Specifically, ozone is generated in the gas state using oxygen or pure oxygen in the air, and when it is applied to water treatment, it is used by dissolving in a liquid phase. In a relatively short time the residual ozone in the liquid state is unstable and the oxygen, and is converted with _{^{water, HO 2 -, O 2 -}} , O 3 - , through an intermediate product such as a bar, these OH radicals to generate OH radical is higher than the ozone itself Because of the potential difference, it has a characteristic of reacting with a large number of organic substances at high speed. The type of ozone generator 1 can be used without particular limitations such as an ultraviolet ozone generator, an electrolytic ozone generator, an silent discharge ozone generator, and the like.

On the other hand, the ozonated liquid stream is sent to the first activated carbon filter to remove other contaminants not removed at the front end by adsorption. That is, suspended solids, ionic dissolved substances, nonionic dissolved substances, etc. contained in the liquid stream are difficult to remove by conventional flocculation or sand filtration, and in the present invention, the contaminants are effectively removed by activated carbon filtration. .

Prior to filtration of the first activated carbon, it may optionally be subjected to a secondary treatment tank 9 and then transferred to the first activated carbon filter. Activated carbon is mainly manufactured by firing at high temperature using bark of wood, wood, coal, etc. as a raw material, and is classified into plant-based and mineral-based according to raw materials, and also classified into granular and powdered coal according to shape.

Activated carbon usable in the present invention can be used without particular limitation to the kind known in the art, preferably about 8 to 30 mesh particle size, specific surface area of about 800 to 1500 m 2 / g, about 100 to 1000 nm One having a pore size and a density of about 0.4 to 0.5 g / cm 3 is used.

Typically, the tank filled with granular activated carbon (Granular Activated Carbon) formed into a granular form can be passed through the ozone-treated liquid flow in a top-down manner to effectively adsorb organic matter and the like.

In the embodiment shown in FIG. 1, the highly treated liquid stream is preferably each process adjusted to meet the water quality criteria of Table 2 below, at least a portion of the liquid stream being sent to a subsequent stage water purification unit, the remainder being Can be used as heavy water such as building water, landscape water, wetland water. For example, if the demand for water / drinking water is high, the amount of highly treated water delivered to the water purification unit may be increased, while if the demand for heavy water is high, the amount of highly treated water delivered to the water purification unit may be reduced. . In order to more easily achieve this flexibility of the operation mode, it is preferable to utilize the recycling tank 12, the liquid flow that is not transferred to the subsequent water purification unit, if necessary through the recycling tank may optionally be the first activated carbon filter It can also be used as backwashing water for desorbing the substance adsorbed on the activated carbon in the inside, and can also be used as backwashing water in the second activated carbon filter 15 in the subsequent purification section, and the desorption contaminant-containing flow after the back washing treatment. May be conveyed to the equalization tank 1 (refer the dotted line in FIG. 1).

The liquid flow, ie, the first activated carbon filtrate, transferred from the advanced processing unit is filtered in a microfilter 13 equipped with a micro-filter to remove and remove some suspended matter. In particular, the microfilter as a pretreatment of the reverse osmosis (R / O) filtration plant has a great influence on the efficiency of the rear end plant. That is, in the case of reverse osmosis filtration equipment, since the contamination of the membrane increases gradually as the operation time elapses, and the treatment efficiency is lowered, the microfilter is disposed at the front end to minimize the contamination of the reverse osmosis membrane.

The microfiltrate is then transferred to a reverse osmosis filter (14), which is a method of pressurizing the membrane for membrane separation by osmosis by applying a pressure greater than osmotic pressure from the higher to the lower concentration. In contrast, the concentration is transmitted from the higher side to the lower side.

Asymmetric cellulose formed as a separation layer (preferably 0.1 to 0.4 ㎛ thickness) for the separation effect on the support layer (preferably having a thickness of about 30 ~ 70 ㎛, porous material) as a material of the reverse osmosis membrane Acetate or aromatic polyamides can typically be used. More preferably, polyamide based membranes are used.

In the embodiment of the present invention, typical properties of the cellulose-based membrane and the polyamide-based membrane which can be used as the reverse osmosis membrane are described in Table 3 below, but the present invention is not necessarily limited thereto.

According to the present invention, the reverse osmosis filter can be used in various types, typically tubular (spiral type), spiral (spiral type), hollow fiber type, plate and fram type, rotating plate type (rotary disk type).

The filtrate by the reverse osmosis filter 14 is transferred to a second activated carbon filter 15, which will be described later, while the concentrated water remaining after filtration is discharged, preferably solidified in the evaporative concentrator 17, and prevented air or the atmosphere. Treatment is carried out in prevention facility 18.

The second activated carbon filter 15 is filtered in the same manner as the first activated carbon filter 10 described above. The second activated carbon filter 10 is different from the first activated carbon filter in order to improve the water taste of the reverse osmosis filter treated water, remove odor and color, and reverse osmosis membrane. It serves to increase the pH decrease by. As described above, the adsorbed material may be desorbed by the backwash water flowing from the recycling water tank 12, and the treated water containing the desorbed material may be transferred to the equalization tank 1. That is, the first and second activated carbon filters are backwashed to remove material deposited in the filter, so that the backwash water generated after the treatment is transferred to an equalization tank. This backwashing process is not performed during normal operation and can be performed periodically for maintenance purposes.

The treatment liquid discharged from the second activated carbon filter is transferred to the ultraviolet sterilizer 16 and subjected to ultraviolet treatment. This method denatures and kills the DNA of bacteria and viruses at a wavelength of 254 nm for sterilization. By such ultraviolet sterilization treatment, bacteria and the like can be sterilized to a level of 99.9% or more so as to be suitable for drinking water / water. In particular, it does not affect the active ingredients such as taste, color, properties, minerals, etc. of water, and can be directly connected to the piping line and used as it is.

The water quality of the treated water discharged from the water purification unit needs to reach a degree suitable for use as constant / drinking water, and considering each of the constituent steps (ie, microfiltration, reverse osmosis membrane filtration, second activated carbon filtration, and ultraviolet light). Process conditions in sterilization) can be controlled. For example, it is preferable to satisfy the drinking water quality standards shown in Table 4 below, but the present invention is not necessarily limited thereto.

TABLE 4

The greatest advantage of the wastewater treatment apparatus and method according to the present invention is not only can utilize all of the generated wastewater as described above, but also wastewater in heavy water (building water, landscaping water, wetland composition water, etc.) and drinking water / water at the same time. And by adjusting each flow rate. Therefore, it is excellent in terms of commercialization because it is possible to process and recycle the total amount of wastewater discharged from an industrial or residential environment located in a clean area, for example, a water source protection zone, to obtain water and drinking water / drinking water.
