The present invention relates to a wastewater treatment system for purifying wastewater such as manure wastewater, livestock wastewater, kitchen sewage, and other household sewage, and more specifically, to efficiently treat wastewater and livestock wastewater generated in a toilet or livestock house. The present invention relates to a wastewater treatment system for purification and reuse.

With the development of industry, the generation of waste water is gradually increasing, and even in the case of water shortage due to the extreme weather caused by the warming phenomenon, it is an urgent task to be solved worldwide. . Therefore, in Europe, where much attention is paid to environmental protection, much research has been conducted on the purification and reuse of household wastewater, and it is also applied in many homes and workplaces. However, these conventional devices for wastewater purification and reuse have many problems in practical application because their configuration is complex and large in size or expensive to manage and operate.

Much research has been done on wastewater purification treatment in Korea. Among them, utility model registration application No. 1993-2216 (a wastewater purification facility using anaerobic and aerobic contact circulation method and its treatment method) uses microorganisms. In order to purify the waste water, the sedimentation tank for sedimentation and separation of solids and contaminants contained in the influent wastewater, the first and second anaerobic filter tanks filled with anaerobic mediators to remove nitrogen components and improve organic matter removal effect in the wastewater, Air lift pump for filling the contact material including the aerobic microbial layer to separate and remove the organic matter, the waste water from the first and second contact aeration tank equipped with aeration device into the center towel, and the circulation of the settled circulating water and Settling tank with metering device, disinfection tank to finally disinfect wastewater and discharge tank to discharge final treatment water Is one that configured by concatenated across the discharge side of the treated water from the waste water inlet side.

However, the above technology does not have facilities and processes for periodically backing anaerobic media and discharging the backwashed water. As a result, the contact area between wastewater and media is reduced due to the media closure, and the treatment efficiency is lowered. Long-term sedimentation leads to a decrease in crude treatment capacity and odor, and by supplying circulating water from the sedimentation tank to the anaerobic filtration tank, sludge (sediment) is deposited in the anaerobic filtration tank to worsen the anaerobic condition and discharged directly through the sedimentation tank. There is a problem such as the leakage of residual pollutants.

On the other hand, Patent Application No. 2000-54525 has been proposed to solve the above problems, as shown in Figure 1, through the attachment filtration tank after the waste water is circulated to the anaerobic, aerobic state through the circulation tank and the contact aeration tank After the final treatment, the sediment that is impeded by the treatment efficiency is effectively discharged, and microorganisms are activated, and anaerobic / aerobic contact circulation and adhesion filtration are used to maximize the treatment efficiency by removing residual pollutants.

The patent application No. 2000-54525 and the sedimentation separation tank 91; In order to decompose the treated water overflowed from the sedimentation tank into anaerobic microorganisms, there are circulating water tanks 1, 2 and 92 (93, 93) each having an anaerobic medium, and the circulating water tanks 1 and 2 are excessively attached to the anaerobic medium. Includes a customs office for the dropping of sludge; Contact aeration tanks 1 and 2 disposed adjacent to each other, including an aerobic media for decomposing and treating the treated water overflowed from the circulation tank 2 into aerobic microorganisms, and backwashing pipes and diffusers for dropping sludge that is excessively attached to the aerobic media. Two chambers (94, 95), wherein part of the treated water in the contact aeration tank two chambers is recycled to the one circulation chamber through a circulation pipe; A settling tank (96) for receiving the treated water flowed from the two contact aeration chambers to settle the sludge, and at the same time, transporting and discharging the sludge to the settling separation tank through a surplus sludge conveying line through an air lift; An attachment filtration tank (97) for further processing the residual contaminants contained in the treated water flowing from the sedimentation tank as an adhesion medium, but the excess sludge in the adhesion medium by dropping the sludge removed at the same time with a backwashing tube installed in the attachment filtration tank A backwash water conveying pump for transporting and discharging the sewage separation tank through a backwashing pipeline; It is configured to include a blower 90 for performing aeration, backwash, and airlift necessary for each tank.

The patented technology configured as described above allows the solids or contaminants contained in the wastewater to be separated into the sedimentation tank for sedimentation treatment, and the primary treatment water flowing out of the sedimentation tank includes the anaerobic media, respectively. Nitrogen is removed by anaerobic microorganisms by sequentially supplying one tank and two circulation tanks, and the treated nitrogen is sequentially flowed into one contact aeration tank and two contact aeration tanks each containing an aerobic medium, and aerated at the same time into each contact aeration tank. The activation of aerobic microorganisms decomposes the organic matter, the treated water decomposed in the organic matter is introduced into the sedimentation tank to precipitate the organic matter in the tertiary treatment water, and the treated water flowing in the sedimentation-precipitated sedimentation tank includes an adhesive including a contact material. Activated aerobic microorganisms by supplying oxygen to the filtration tank to remove residual pollutants. After dwelt is adapted to process the waste water in order to discharge.

However, the wastewater treatment device of the patent has a complicated structure and requires several steps, so the space occupied by the device is too large, and the oxygen must be supplied artificially, resulting in a lot of trouble and economic burden, and conclusively, wastewater. In the treatment, it is not possible to purify until it becomes reusable water, it can be treated only to the level that can be discharged, it can not bring the effect of reuse of the treated water.

In addition, the waste water treatment device of the patent is configured to discharge the waste water is determined that the purification of the waste water is finished when the waste water proceeds to each set once, rather than by discharging water that has not completely removed the pigment or smell, etc. Can cause pollution and thus destroy ecosystems.

The wastewater treatment apparatus of the present invention includes a storage tank in which wastewater is introduced and stored, an aeration tank for receiving and aeration of wastewater from the storage tank, a precipitation tank for receiving sedimented wastewater from the aeration tank, and a sedimentation tank for precipitating sediment, and the wastewater received from the sedimentation tank. In the wastewater treatment device consisting of a first reaction tank for filtering the second reaction tank for filtering the filtered water supplied from the first reaction tank, and the second reaction tank, each of the collecting tank is installed in each of the 1.2 reaction tank between the respective collection tank and the reaction tank A pump is installed at the pump to circulate the purified water, purify and discharge the purified water discharged from the collection tank installed in the second reaction tank to the place of use, and the waste water generated after being used at the place of use is supplied to the storage tank again to be the waste water. It is designed to be purified again and reused. .

The wastewater treatment apparatus of the present invention is mainly for purifying and reusing or externally discharging livestock wastewater generated in a toilet or livestock house, and manure wastewater generated in a home toilet can be purified and reused, and livestock Wastewater is based on clarification and external discharge, but in some cases they are purged to allow external discharge or re-use.

The wastewater treatment apparatus of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 2, the waste water is supplied to the storage tank 10, and the waste water supplied to the storage tank 10 is supplied to the aeration tank 20 so that aeration occurs and primary purification occurs. At this time, since the storage tank 10 and the aeration tank 20 is provided with a crushing means (not shown), the sludge present in the waste water is crushed by the crushing means is supplied to the next settling tank or reaction tank together with the waste water. That is, in the aeration tank 20, the waste water after the first purification is entered into the settling tank 30, and the sludge having large particles is settled, that is, the boiling water is supplied to the first reaction tank 40. The waste water supplied to the first reactor is purified while passing through the media filled in the first reactor (40).

The purified water purified in the first reaction tank 40 is supplied to the second reaction tank through the water collecting tank 41 installed in the first reaction tank 40 and the water collecting tank 51 installed in the second reaction tank 50. Activated carbon is charged in the second reaction tank 50 to perform secondary purification of the purified water passing through the first reaction tank 40 and to remove pigments and odors remaining in the purified water. The purified water from which the dye and the odor are removed in the second reaction tank is refluxed to the collecting tank 51 installed in the second reaction tank 50 and discharged to the outside or supplied to the use place 60 for reuse. As described above, when the livestock wastewater is purified, it is discharged to the outside rather than reused, and when the home wastewater is purified, it is supplied to the place of use and reused.

However, the livestock wastewater is not necessarily purified and discharged, and the manure wastewater is not purified and reused, but depending on the method of operating or operating the purification system of the present invention, both livestock wastewater and manure wastewater may be purified and reused. Alternatively, both livestock wastewater and manure wastewater can be purified and discharged externally.

In the case of reusing purified water, the use place 60 will mainly be a toilet tank, a water storage tank, an item washing tank, etc., and the water used here will be returned to the storage tank 10 as waste water again. Storage tank (10) → aeration tank (20) → sedimentation tank (30) → first reaction tank (40) → the corresponding sump (41) installed in the first reaction tank of the waste water purification procedure described above) → the second reaction tank (50) → the water tank 51 installed in the second reaction tank → the use destination 60 → the storage tank (10) is continuously circulated in order to repeat the purification of the waste water and use of the purified water. On the other hand, when the purified water purified by the present invention to be discharged to the outside may be discharged directly from the water collecting tank 51 installed in the second reaction tank (50).

The filter medium filled in the first reactor 40 is made of porous wood chips, mica chips, synthetic resin chips, ceramic chips, etc., and can be effectively removed by the filter medium to remove all colors and odors of the waste water. Thus, the final discharged water can be colorless and odorless to the same extent as ordinary water. That is, when wastewater is supplied to the first reaction tank filled with the filter medium, the waste water passes through the pores of the filter medium and between the filter medium and the filter medium, and is sufficiently purified by the microorganisms for wastewater purification and discharged into clear water.

However, in order to achieve such an efficient purification, the microorganisms must be completely cultured in the media of the first reactor, the amount of dissolved oxygen necessary for the microorganisms to fully function, and the purified water in the first reactor must It should be supplied continuously.

In order to create such an environment, a bypass pipe 42 having a pump P is connected between the first reaction tank 40 and the corresponding sump 41 installed therein, so that the pump P is connected to the first reaction tank ( By pumping the purified water collected in the sump (41) installed in the 40) to the first reaction tank (40) is made a continuous circulation of water purification (at least two times) between the first reaction tank and its corresponding sump (41) To further increase the purification efficiency.

In addition, between the corresponding collection tank 41 and the settling tank 30 installed in the first reaction tank 40 of the present invention by connecting the bypass pipe 31 in which the pump P is installed and installed in the first reaction tank 40. By pumping the purified water of the sump (41), the circulation of the purified water (at least two or more times) between the first reaction tank (40), the sump (41), the settling tank (30) is made to further increase the purification efficiency of the waste water.

In addition, between the second reaction tank 50 and the corresponding sump 51 installed therein, the bypass pipe 51a in which the pump P is installed is connected and installed like the first reaction tank 40 and the sump 41 installed therein. By pumping the purified water of the sump 51 installed in the second reaction tank 50, a continuous circulation (at least two or more times) is made between the second reaction tank 50 and the corresponding sump 51 to further increase the purification efficiency of the purified water. . However, since activated carbon is filled in the second reaction tank 50, the odors and pigments remaining in the purified water are completely removed.

In the past, a plurality of reactors were installed to increase the purification efficiency. Therefore, a large space was required to install a plurality of reactors. However, in the present invention, by purifying the circulation of purified water by pumping between the first and second reaction tanks and the respective collection tanks, the purification efficiency can be improved even in a narrow space.

Another characteristic configuration for increasing the purification efficiency in the present invention is to form both the upper and lower sides of the first reaction tank 40 made of a porous material having a breathable. The reason for using a porous material that is breathable is that oxygen in the atmosphere naturally flows into the first reactor to increase the oxygen dissolution rate therein, so that aerobic and anaerobic microorganisms inhabiting the media filled in the first reactor are smoothly cultured. Can be achieved, thereby maximizing the purification efficiency.

As such, forming both upper and lower sides of the first reactor 40 with a porous porous material is organically combined with other components of the present invention to further increase the wastewater purification efficiency, but is also a purification efficiency as such. It can be applied to the conventional wastewater treatment system because it can maximize.

On the other hand, if the amount of the purified water supplied from the corresponding collecting tank 41 of the first reaction tank 40 to the corresponding collecting tank 51 of the second reaction tank 50 is too large and the collection tank overflows, the overflow purified water is bypassed. If the amount of wastewater supplied to the aeration tank 20 and the sedimentation tank 30 is too large and overflows through the pipe 51b, it is also through each of the bypass pipes 20a and 30a. It is supplied to the storage tank 10.

3 shows another embodiment of the present invention, which is the wastewater treatment apparatus and storage tank 10 of FIG. 2, the aeration tank 20, the settling tank 30, the first reaction tank 40 and the corresponding collection tank 41, The purified water is stored between the second reactor 50 and the user 60 having the same configuration as the corresponding collection tank 51, the second reactor 50, and the destination 60 of the second reactor, and merely removing pigments and odors. The storage tank 52 is to be installed, which is to store a large amount of purified water, so that the purified water can be smoothly supplied at any time when the purified water is required in the use (60).

In addition, the waste water generated after being used in the use place 60 is supplied to the storage tank 10 again through the bypass pipe 60a, so that the aeration tank 20 → precipitating tank 30 → first reaction tank 40 → first Applicable water collecting tank (41) of the reaction tank → Applicable water collecting tank (51) of the second reaction tank → Second reaction tank (50) → Applicable water collecting tank (51) → Storage tank (52) of the second reaction tank → Where to use (60) → Storage tank (10) By continuing to purify the cycle and reuse of the purified water purification can not only contribute to the increasingly serious water shortage, but also has the advantage of preventing water pollution.

The description according to FIG. 3 also illustrates the reuse of purified water purified using the wastewater treatment apparatus of the present invention, and when the purified water is to be discharged from the corresponding collection tank 51 installed in the second reaction tank 50. Just discharge it.

In addition, the first reaction tank 40 of another embodiment of the present invention is divided into each of the front reaction tank (40a) and the rear reaction tank (40b) filled with the filter medium to purify the waste water as shown in Figure 4 and each of the front and rear The reaction tanks are provided with the corresponding collection tanks 41a and 41b, and the purified water purified in the front reaction tank 40a is collected in the corresponding collection tank 41a installed in the front reaction tank 40a and he is supplied to the rear reaction tank 40b. After the second purification, the water is collected in the water collecting tank 41b.

Each of the bypass pipes 43a and 43b provided with the pump P is installed between the front reaction tank 40a, the corresponding sump tank 41a and the rear reaction tank 40b, and the corresponding sump tank 41b installed thereon. With the operation of the pump, the purified water collected in each corresponding tank is re-supplied to each reactor, and the purification is repeated several times to increase the purification efficiency.

In this way, the purified water collected in the corresponding collection tank 41b of the rear reaction tank 40b is supplied to the second reaction tank 50 filled with activated carbon through the corresponding collection tank 51 installed in the secondary reaction tank 50 and the rear Water storage tank 52 to remove the pigment and odor remaining in the purified water passed through the reaction tank (40b) and the purified water from which the pigment and odor has been removed again through the corresponding collection tank 51 of the second reaction tank (51) It is stored in and supplied when the purified water is needed at the destination 60.

Then, the wastewater generated after the wastewater treatment apparatus of FIG. 4 is also used in the use place 60 is supplied to the storage tank 10 again, and the aeration tank 20 → the settling tank 30 → the front reaction tank 40a → the corresponding collection tank 41a. → the rear reaction tank (40b) → the sump tank (41b) → the second reaction tank (50) → the sump tank (51) → the reservoir tank (52) → the place of use (60) → the storage tank (10) to continue to purify and purify To make the integers reused. However, when it is desired to discharge the purified water, it may be discharged directly from the water collecting tank 51 installed in the second reaction tank 50.

The wastewater treatment apparatus of the present invention as described above saves energy by allowing the overflow of the wastewater and purified water to be supplied to each tank or bypassing the power supply without bypassing the power to the minimum. It also has the advantage of preventing waste of water by purifying and discharging wastewater supplied to the storage tank, or by reusing the purified water.

In addition, sediment may be deposited in each tank (aeration tank, sedimentation tank) of the present invention, so that pipes for draining the sediment are installed in the lower part of each tank, and the pipes are connected to the storage tank to install the sediment deposited in each tank. In order to be purified again in the above purification procedure.

Wastewater treatment apparatus of the present invention as described above has the advantage that it can be simply installed in a small area because its configuration is simple and does not require much space for its installation, and also through the continuous circulation between the reaction tank and the sump The purification efficiency was increased, and the purified purified water was directly refluxed for reuse, and the upper and lower sides of the first reactor were made of a porous porous material to supply oxygen from the air to the dissolved oxygen rate of the purified water. It is to maximize the purification efficiency by increasing the bar, compared to the conventional wastewater treatment system has a similar improvement effect.
