The present invention relates to a heavy water treatment apparatus using a microbial carrier, and more particularly, to treat / purify domestic water such as toilet wash water or washbasin wash water, by treating heavy water using a microbial carrier, aeration device and a plurality of reaction tanks. The present invention relates to a heavy water treatment device capable of saving water resources and enabling eco-friendly construction.

Water plays a number of important roles in the biosphere and is indispensable for our lives, such as keeping our planet's temperature constant. Formation and maintenance of all living things, even ecosystems, is possible in the presence of water, and about 70% of our bodies are water. In other words, water is the source of life and life itself.

However, with the development of the industry, human beings have achieved their present development through the destruction of the environment, but in return they are threatened with life. Water pollution, along with air and soil pollution, must pose a significant threat to human survival.

As an effort to solve such water pollution, reuse of water, that is, utilization or treatment of heavy water is required.

"Heavy water" refers to water that can be purified by additional water purification facilities on the assumption that water resources are recycled. Rainwater refers to rainwater. Since the land is almost entirely covered with buildings, asphalt and concrete pavements, it is not an underground infiltration of rainwater, causing groundwater depletion and causing urban heat island and drying. In addition, it does not penetrate into the ground and is temporarily drained into the sewerage, which causes urban flooding. In other words, due to urbanization, underground penetration decreases, causing changes in the water circulation, increasing the flow rate during flooding, decreasing the normal flow rate, and adversely affecting the use of water resources. do. Sewage is a general term for wastewater generated in daily life and consists of sewage and rainwater. Sewage is the collection of household sewage from homes, wastewater from factories and workplaces, groundwater, etc. Rainwater is water collected through drainage channels such as roads. The characteristics of sewage are very complex in quality, and vary from region to region, depending on whether the sewage and stormwater are combined or segregated. In addition, quantitative and qualitative changes will be made depending on the regional characteristics of the treatment area, size, human lifestyle, factory operation, time zone, day of the week, and season.

1 is a schematic view of a water treatment apparatus according to a preferred embodiment of the present invention, which is a plan schematic view from above.

Referring to Figure 1, the heavy water treatment apparatus of the present invention is formed in the body 10 having a cuboid structure as a whole is provided with an inlet pipe, discharge pipe, microbial carrier, aeration device, circulation path and the like. The interior of the heavy water treatment device body 10 is divided into a plurality of partitions as shown, divided into a plurality of reaction tanks, depending on the role performed in each reaction tank (100), anaerobic tank (200), anaerobic tank (300) , Sedimentation tank 400, storage tank 500 is divided.

"Reactor" means each part inside the body 10 which is divided by a partition, and is named in the sense that the reaction for the treatment of heavy water proceeds in each part.

In Figure 1, the arrow means the inflow path of the influent (wash water), in particular, the thick solid line arrow means that the passage formed in the partition wall is formed on the upper side and moves to the upper side when the influent flows to the next reaction tank, The dashed arrow means that the passage formed in the partition wall is formed at the lower side and moves to the lower side when the inflow water is transferred to the next reactor. As shown in Figure 1 from the anaerobic tank 100 to the sedimentation tank 400, the process of passing the influent is shown by a thick solid arrow and a thick dotted arrow sequentially, which is the path of the partition wall corresponding to the influent path is formed alternately up and down This means that the influent flows through the upper side-> the lower side-> the upper side-> the lower side ..... This is to increase the residence time of the influent to achieve the maximum water purification efficiency.

The structure of the heavy water treatment apparatus of the present invention will be described according to a process in which household water such as toilet bowl wash water and washbasin wash water flows into and flows into the heavy water treatment apparatus.

First, the most polluted toilet water in the living water is introduced into the anaerobic tank 100 through the toilet washing water inlet tube 140 formed on one side of the anaerobic tank (100).

The anaerobic tank 100 is divided into a plurality of reaction tanks by a plurality of partition walls 152 and 154 erected in a vertical direction, and an anaerobic environment in which anaerobic microorganisms propagate is formed. The anaerobic tank 100 generally releases / removes phosphorus by using organic materials by accumulation microorganisms (PAO) in the absence of air (oxygen).

Anaerobic tank is the first anaerobic tank 110, the second anaerobic tank 120, and the third anaerobic tank 130, which is divided by the two anaerobic bulkhead first bulkhead 152, anaerobic tank second bulkhead 154. Are distinguished. The reason for subdividing the anaerobic tank by the partitions 152 and 154 is to increase the residence time of the influent in the anaerobic tank as much as possible in the limited space.

The toilet washing water from the outside is introduced into the first anaerobic tank 110 through the toilet washing water inlet pipe 140, and is passed through the second anaerobic tank 120, the third anaerobic tank 130, to the aerobic tank 200.

The passage formed in the anaerobic tank first partition 152 and the passage formed in the anaerobic tank second partition 154 are opposite to each other up and down, that is, the passage of the anaerobic tank first partition 152 is on the lower side, and the anaerobic tank second partition 154 ) Is formed on the upper side (see FIG. 2). Accordingly, the movement of the inflow water (wash water) from the first anaerobic tank to the second anaerobic tank is at the lower side as shown by the thick dashed arrow, and the movement of the influent from the second anaerobic tank to the third anaerobic tank is at the upper side as shown by the thick solid arrow. Next, the inflow of the adjacent intake tank 1 in the third anaerobic tank is made to the lower side again.

As such, the passage formed in the anaerobic tank first partition wall 152 and the passage formed in the anaerobic tank second partition wall 154 are formed on the upper and lower sides of each other to form an inflow channel up and down. This is to ensure that the reactions at will have maximum efficiency.

Inflow water in the third vessel 130 is moved to the first vessel 210 through the lower side.

The aerobic tank 200 is a reaction tank in which oxygen is supplied to decompose organic matter by aerobic microorganisms. The aerobic tank 200 of the present invention is divided into a first aerobic tank 210 and a second aerobic tank 220 by a vertical aerobic tank partition 240, the size of the second aerobic tank 220 is the first aerobic tank ( It is formed more than two times larger than the size of 210, which is the first anaerobic tank 210 serves as a buffer of the anaerobic tank 100 and the aerobic tank 200, anaerobic microorganisms flow into the second aerobic tank in which aerobic microorganisms mass breed It prevents it from becoming.

The first aeration tank 210 and the second aeration tank 220 are formed with aeration devices, respectively, to create an aerobic environment to promote the decomposition of organic matter by aerobic microorganisms.

The aeration device is a device for supplying a large amount of oxygen (air) at a time, preferably a jet aerator may be used. Jet arate uses the principle of the venturi tube, so that water passes through the venturi tube and oxygen is supplied to the nozzle due to the pressure difference, and oxygen is supplied to each reactor. As oxygen is supplied, decomposition of organic matter occurs by microorganisms.

The second vessel 220 is formed in the washbasin washing water inlet pipe 230 through which the washbasin washing water, which is relatively clean (cleaner than the toilet wash water), is introduced. The reason why the washbasin washing water inlet pipe 230 is formed in the aerobic tank 200 is to prevent the anaerobic tank from growing too large by distinguishing it from the inflow of the toilet bowl washing water.

The passage formed in the aerobic tank partition wall 240 is formed in the upper and lower sides opposite to the passage passing from the anaerobic tank to the aerobic tank, in order to allow the influent to form a flow path up and down.

The influent flowing through the second vessel moves to the anaerobic vessel 300.

The aggression vessel 300 is partitioned into a plurality of reaction vessels (advance vessels, 310, 320, 330, 340, 350, 360, 370) by a plurality of partition walls erected in the longitudinal direction. The anaerobic vessel 380 may be a reaction vessel in which an anaerobic environment and an aerobic environment coexist.

That is, each of the aerobic reactors is formed with a central diaphragm 380 which is divided into upper and lower portions, respectively, a central diaphragm 380 is formed with a passage for inflow of water, and each reactor is based on the central diaphragm. It is divided into and the lower reaction tank, the anaerobic microbial carrier is installed in the lower reaction tank, the aeration device is formed in the upper reaction tank, respectively. That is, each reaction tank of the anaerobic tank 300 will be referred to as an aerobic tank that provides an aerobic environment by the aeration device, the lower part is an anaerobic tank providing an anaerobic environment. In this way, the anaerobic and aerobic environments coexist in the sense of aggression in the sense of coexistence.

As the aeration device formed in the aerobic vessel, a jet aerator is preferably used.

The influent passes through the aerobic vessel 300 in which the anaerobic and aerobic environments are alternately continuous, so that not only phosphorus removal but also decomposition of organic matter is continuously and continuously performed. In the anaerobic climate, the anaerobic and aerobic environments are repeated while the inflow of inflow water is not carried out. The water quality is sequentially passed through each hatch.

Each reaction tank of the aerobic vessel partitioned by the partition wall is formed with the inlet and the outlet being introduced in the up and down opposite sides. That is, in each reactor, when the inlet is formed on the upper side, the outlet is formed on the lower side, and when the inlet is formed on the lower side, the outlet is formed on the upper side. Accordingly, the inflow water passing through the plurality of reaction tanks in the aggression tank crosses the upper side and the lower side, thereby increasing the residence time in the aerobic vessel to maximize the purification efficiency.

The influent water passed through the agitation vessel 300 is moved to the settling tank (400).

However, some of the influent is returned from the reaction tank 370 at the end of the anaerobic tank via the circulation path 600 to the second tank 220. As some of the inflow water passing through the anaerobic tank in which the organic matter is decomposed again flows into the second vessel 220, the turbidity of the second aerobic bath will be reduced, thereby helping to decompose the organic matter due to the aerobic environment.

The settling tank 400 is supplied with the inflow water from the aggression vessel 300, so that the sediment in the influent is precipitated. In the sedimentation tank, a separate aeration device is not installed, and the sedimentary substance is settled to the bottom before being taken out.

Influent water passed through the settling tank 400 is moved back to the storage tank (500). Storage tank 500 is a place for storing the treated water before finally discharged to the outside.

The storage tank 500 of the present invention is divided into a first storage tank 510 and a second storage tank 5200 by vertical partition walls, and aeration devices are formed in the first storage tank 510 and the second storage tank 520, respectively. It is then used as the wash water recycled as final water, while stabilizing BOD levels more. The aeration device may use the jet aerator described above.

The treated water in the reservoir 500 is discharged to the outside through the treated water discharge pipe 530 connected to the second reservoir 520. The treated water discharged through the treated water discharge pipe 530 is discharged to the outside to be recycled as household water such as toilet water.
