Description

Multi filtration facility {Multitude Filter Device}

The present invention relates to a multiple filtration system configured to effectively clean and reuse contaminated water discarded after use in a facility using a large number of people or a large laundry.

In general, a large amount of water is used in public saunas, swimming pools and large laundries, which are contaminated by various chemicals, sludges and suspended solids.

If the polluted water is discharged through the sewer, it not only pollutes the environment but also uses too much water, increasing the cost of operating the facility or treating the wastewater, causing a great burden, and causing water exhaustion and energy waste. As the water is generated, contaminated water is filtered by using various filtration facilities and recycled in a circulating manner, and efforts are being actively made to reduce the amount of water used.

In general, as a method used to clean the contaminated water cleanly, the sand filter needs to replenish or completely replace the filter medium over time, and the water quality is not stable due to incomplete regeneration of the filter medium. have.

In addition, the filter using diatomaceous earth has to refill the filter material manually every time, and there is a high risk of deterioration of water quality due to lack of cleaning, and it takes a long time to backwash, and the cartridge type filter requires a short-term filter change. If contaminated, there is a disadvantage that the water quality is sharply worse.

In addition, the method using the adsorption power of activated carbon can effectively remove soluble organics, phosphorus and other contaminants, and is known to be very effective for removing surfactants, colors, heavy metals, and residual chlorine.

In connection with such a filtration facility, for example, Patent No. 0798717 describes a method of "clean water" in which activated carbon supplied from an activated carbon tank is wet-pulverized with water and then added to a raw water tank, and the raw water for filtration is filtered by a membrane module. Activated carbon addition method and water purification treatment method in treatment "are disclosed.

However, the patent remains in a very simple manner in which activated carbon is pulverized, mixed in raw water and filtered again, and for this purpose, an activated carbon pulverizing device, a mixing device, and a filtration device must be separately provided. .

In addition. Patent No. 0429610 discloses a "wastewater treatment system using an activated carbon filtration tower," but in this case, the activated carbon filtration tower absorbs and filters downstream wastewater flowing downward. It accumulates intensively on top of the packed bed.

Therefore, even if air and washing water are supplied from the lower part of the activated carbon filter tower, the contaminants on the upper part of the activated carbon packed bed cannot be completely removed. Therefore, the operator must open the manhole cover and clean the contaminants. Since the washing is performed while filled with raw water, there is a limit in that it is not possible to properly handle the polluted particles floating in the filter tower.

In view of this problem, Patent No. 0864642 discloses "biological activated carbon adsorption filtration apparatus" which adsorbs and filters raw water by activated carbon in an upflow manner, and at the same time, removes and discharges fine contaminants by back washing and injection of compressed air. Is proposing.

However, the patent requires a somewhat complicated configuration and operation because the air must be blown by the compressor, and because the compressed air is strongly injected by the compressor during backwashing the raw water, not only the inside of the adsorption tower is disturbed by the injected air, but also a fine filtration filter. The fine particles filtered by include a problem that it is difficult to discharge to the outside even after the backwashing process.

Korean Patent Laid-Open Publication No. 1999-0010045 (published on February 5, 1999)-a constant filtration system using activated carbon. Registered Patent No. 0429610 (registered April 19, 2004)-Wastewater treatment system using activated carbon filtration tower. Patent No. 0464243 (registered on Dec. 21, 2004)-A foamed polypropylene media impregnated with activated carbon, a manufacturing method thereof, and a biofilm filtering device using the same.

The present invention is to solve the conventional problems as described above, an object of the present invention, to maximize the purification capacity for contaminated water to reuse a large amount of water, simply install the equipment itself in a relatively small area In addition, it is possible to provide multiple filtration facilities that can greatly reduce the overall operating costs including facility costs due to the reuse of materials.

The present invention for achieving this object is a multiple filtration equipment for purifying contaminated water after collecting and dewatering the wastewater containing sludge, the water supply pipe is fed through the contaminated water, and through the water supply pipe It consists of a tank consisting of filtration rooms partitioned by partitions installed so that the height is gradually lowered in order to purify the contaminated water in multiple stages, and stainless steel meshes, each of which is filled with particulate filtration material. The water tank is provided with an air generator for supplying air into the water tank to back up the activated carbon, including a salt water tank for supplying the brine in which sodium chloride is dissolved at a high concentration.

In addition, the filtration material to be filled in the stencil of the filtration room is activated carbon, anthracite in the stencil of the filtration room, ion exchange resin in the stencil of the filtration room, talc is sequentially filled in the stencil of the filtration room It is constructed by losing.

In addition, a lifting unit for drawing a stainless steel net is provided around the tank, and the lifting unit includes a support beam and a rail horizontally disposed on an upper end of the support beam, and constitutes a hoist for sliding along this rail. It is.

In addition, the water tank is provided with a water supply line for supplying water to wash the filtration materials in the stainless steel network and a discharge path for discharging the water discarded after the washing to the outside.

The present invention can greatly improve the overall efficiency by allowing the contaminated water to be purified step by step through the various filtration materials including activated carbon in the stainless steel by the above-described features, multi-stage in one tank Since the purification function can be performed, the facility itself can be installed in a small area, which greatly reduces the overall operating cost including the initial facility cost.

In addition, since the purified water can be reused without discharging it to the outside, it is possible to prevent environmental pollution in advance, as well as to clean and reuse it when contaminating activated carbon or filtration materials. You can also expect the effect to reduce.

1 is a configuration diagram of an adsorption reaction apparatus disclosed in Korean Patent No. 0483694,
Figure 2 is a schematic configuration diagram for explaining the multiple filtration equipment according to the present invention,
3 is an enlarged view of the configuration of the water tank shown in FIG.
Figure 4 is an enlarged view showing the structure of the stainless steel mesh mounted in the tank.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, but the specific structures and functions of the present invention are not limited to the embodiments described in the specification because they illustrate only one configuration example.

First, as an example related to the technical contents of the present invention will be described with respect to the known technology disclosed in the Patent No. 0483694, after deriving the problems according to the configuration and effect of the present invention will be described later.

As shown in FIG. 1, the activated carbon reaction tank 10 for introducing the treated water after the primary treatment by a biological or physical chemical treatment method and stirring the activated carbon and the reaction water passing through the activated carbon reaction tank 10 are stirred. Coagulation tank 20 for coagulation by means of the present invention, a pumping tank 30 for pumping wastewater passing through the coagulation tank 20, and for separating activated carbon from the reaction water passed through the pumping tank 30. It consists of the fiber filter 40 and the final processing tank 50 which stores and discharges the water which passed the fiber filter 40, and discharges it.

In addition, the activated carbon dissolution tank 60 further comprises an activated carbon dissolution tank 60 for providing an activated carbon solution to the activated carbon reaction tank 10 and a flocculant dissolution tank 70 for providing a coagulant solution to the flocculation tank 20. ) Is installed between the activated carbon 80 that can supply a large amount of activated carbon.

The treated water after the primary treatment is introduced into the activated carbon coagulation tank 10 to adsorb organic matter or other contaminants in the water, and after the adsorption of contaminants in the activated carbon reaction tank 10 is completed, it is moved to the coagulation tank 20. In this agglomeration tank 20, the activated carbon is agglomerated to an appropriate size to facilitate extraction.

The agglomeration tank 20 is made to agglomerate between activated carbons by stirring by a motor, and when the agglomeration process is completed, the coagulation tank 20 moves to the pumping tank 30 to enter the fiber filter 40 by the filtration pump.

The fiber filter 40 prevents the activated carbon from passing through and transfers only the filtered water including the soluble organic matter to the final treatment tank 50. A backwash pump is connected to the lower end of the final treatment water tank 50 to send the final treatment water to the fiber filter 40 to separate activated carbon.

In addition, by installing a COD measuring device 90 as an automated operation equipment to continuously measure the COD concentration of the influent water, if the COD concentration is lower than the limit weight value, it is possible to stop the operation of the activated carbon adsorption device, COD above the threshold reference value It can be configured to only run actively when concentration influent is introduced.

The powdered activated carbon (particle size about 40 μm) is easily removed from the fiber filter and the activated carbon separated by the backwashing process is sent to a biological treatment process and used as a microbial medium. Activated carbon blocked by the backwashing filtrate in the filter is subjected to the adsorption treatment once more during filtration.

In other words, the activated carbon adsorption reaction is one step in the activated carbon adsorption reaction tank, the two-step process in the filter has the advantage that the organic organic matter removal efficiency is increased.

The activated carbon dissolution tank 60 is injected into the metering pump after diluting with a suitable chemical to facilitate the dissolution of the hydrophobic activated carbon. The activated carbon adsorption reaction tank 10 should be rapidly stirred in order to increase the adsorption reaction efficiency of activated carbon.

In the flocculation tank 20, a flocculant for removing activated carbon and an insoluble organic substance in which water is adsorbed is dissolved, and a flocculator is installed to increase the flocculation efficiency. As the reaction water after the aggregation is completed is introduced into the fiber filter 40 from the pumping tank 30, the adsorption reaction treatment process in the fiber filter 40 is performed.

By the way, in the known technique as described above, since the powdered activated carbon introduced into the activated carbon reaction tank 10 moves to the fiber filter 40 through the flocculation tank 20, powdered activated carbon not separated from the fiber filter 40 is There is a problem that is included in the treated water and discharged to the outside.

In addition, when the activated carbon powder and contaminants contained in the water are adsorbed by stirring, the adsorption efficiency is very low, and the activated activated carbon powder is agglomerated with a flocculant and then separated. do.

In addition, since the facility itself is complicated and bulky, not only a large area is required, but also a large amount of initial facility costs, which leads to a problem of low economic efficiency.

On the other hand, Figures 2 to 4 attached to the view for explaining the multiple filtration facilities according to the present invention, contaminated water discarded after use in public sauna facilities, large laundry shops, etc., supplied into the dehydrator as needed sludge It may be removed or pretreated with chemicals.

This dehydration and subsequent treatment with chemicals is a method commonly used in the purification of general wastewater, and thus detailed description thereof will be omitted.

As described above, the contaminated water during the pretreatment process is put into the filtration facility can be purified and reused.

That is, in the present invention, the filtration equipment includes a water supply pipe 110 to which contaminated water is supplied, a water tank 120 for purifying contaminated water introduced through the water supply pipe 110 in multiple stages, and the water tank 120.

The lower brackets 123a and 123b and the support plate 124 are installed to mount the stainless steel 130 one by one.

The stainless steel 130 has a plurality of small holes 131a formed over the entire circumferential wall, so that the filtration materials made of a plurality of small particles are embedded therein. That is, the stainless steel 130 mounted in the three filtration rooms 122a to 122c in order from the water supply pipe 110 side is filled with activated carbons S1 to S3, and the stenting network 130 of the next filtration room 122d is formed. Anthracite (B), the stented network 130 of the next filtration room (122e) is ion exchange resin (R), the stencil (130) of the next filtration room (122f) is formed by sequentially filling the talc (H), respectively .

Activated carbon (S1 ~ S3) embedded in the stainless steel 130 of the filtration room (122a to 122c) is an amorphous carbon well-developed fine pores made of carbonaceous materials such as coconut shell, wood, lignite, anthracite, bituminous coal as a raw material As an aggregate, it is an adsorbent having a large internal surface area by forming micropores of the molecular size through the activation process.

The activated carbons (S1 to S3) have a large internal surface area of 1,000 m 2 or more per gram, and at the same time, a functional group of carbon atoms attracts the surrounding liquid or gas to adsorb the molecules of the adsorbate, thereby not only purifying air. Adsorption of odor-causing substances or colored substances is used in various fields such as water treatment, food, beverages, and pharmaceutical processing.

Anthracite, which is mounted in the stencil 130 of the filtration room 122d, is a kind of filter medium filtered using anthracite to a particle size of an appropriate size. It is widely used for large scale water treatment.

Carbon, the main component of anthracite, is more resistant to corrosion of water and chemicals than other substances, and is effective in removing iron from contaminated water. Especially, the maintenance time is reduced due to the long filtration time, and compared with sand. Small specific gravity has the advantage of easy separation of suspended solids during backwashing.

In addition, the ion-exchange resin mounted in the stainless steel 130 of the filtration room 122e is a generic term for a porous synthetic resin having a three-dimensional network structure with a non-solubility having ions, and a cation exchange resin, Anion exchange resins and those which do not enter them.

The cation exchange resin is a polymer acid having an acidic group bonded to the mother synthetic resin, and exchanges and removes cations in the aqueous solution. The anion exchange resin is a polymer base having a basic group bonded to the mother synthetic resin. Examples of the exchange resins that do not enter them include yin and yang ion exchange resins and electron exchange resins.

In addition, talc (Talc) mounted in the stencil 130 of the filtration room 122f has been commonly used in the name of "mineral or gobstone", and because it has a smooth property and soft hardness, stoneware (石器) and other Used for carving. The talc is produced by dolomite (白雲岩) and magnesite (Magnesite) secondary degeneration or superbasic rock serpentine (蛇 文石) is hydrothermally modified (熱水 變質).

On the other hand, the partition wall 121 partitioning the tank 120 in multiple stages is configured to gradually lower the height, including activated carbon (S1 ~ S3) filled in each of the stainless steel network 130, anthracite (B), ion exchange resin Water passing through the filtering materials (R), talc (H), etc. flows in stages, and is configured to discharge the purified water stored in the final collection tank (125).

Therefore, the contaminated water flowing through the water supply pipe 110 is introduced into the stainless steel 130 in the filtration rooms 122a through 122c, and is purified while passing through the activated carbons S1 through S3. From the adjacent partition wall 121 from the flow into the stencil 130 of the filtering room (122d) to remove the iron in the contaminated water by the anthracite (B).

Subsequently, it is introduced into the stencil 130 of the filtration room 122e to convert the hard water into soft water by the ion exchange resin R, and is introduced into the stencil 130 of the filtration room 122f. After converting the water contaminated by the natural water is stored in the collection tank 125 disposed on the outside is to be able to reuse the purified water finally clean.

In addition, the brine tank 140 accommodates water in which sodium chloride is dissolved at a high concentration, and the brine is suitably provided into the water supply pipe 110 when the pump P is driven, thereby calculating the degree of contamination of water. oxygen demand).

The salt tank 140 is preferably equipped with a stirring blade 142 that rotates by the drive of the motor 141 to periodically stir to prevent the particles from sinking.

The stainless steel 130 is taken out from the respective filtration chambers 122a to 122f around the water tank 120 to filter substances, that is, activated carbon (S1 to S3), anthracite (B), and ion exchange resin (R). , Lifting unit for washing talc (H) is provided. The lifting unit includes a support beam 160 and a hoist 162 that slides along the rail 161, including a rail 161 horizontally installed on an upper end of the support beam 160.

Each of the stainless steel mesh 130 may be cleaned by spraying high pressure water in a state of being sequentially lifted by the hoist 162 or by pouring the filtration materials in the stainless steel mesh 130 into a separate container. .

The air generator 150 may backwash the filtration materials in the stainless net 130 by supplying air into the water tank 120 through a pipe. This backwashing process can be arbitrarily set to be performed periodically by a controller (not shown).

In addition, the water tank 120 is provided with a discharge path for discharging water discarded after the cleaning is completed, including a water supply path for supplying water used for backwashing the filtration materials.
