On the other hand, the wood chip 56 serves as a house in which the microorganisms live, a plurality of pores are formed, it is preferable that the material is not resistant to corruption due to moisture. Thus, in the present embodiment, cedar is used as the wood chip 56, and the particles of the wood chip 56 are formed to have a size of 5 to 7 mm to filter out solid particles having a relatively large particle size. The solid filtered out is decomposed by the microorganisms cultured in the wood chip 56.

The wood chip is classified by the size of the wood pieces, to maximize the surface area and porosity to promote microbial culture. Herein, the organic material is adsorbed or attached to the pores of the wood chip, and microorganisms nutrient or ingest the organic material to water, carbon dioxide, oxidation or assimilation, and discharge only clear water.

Looking at the configuration of the wood chip as follows.

chief ingredient fibrin 65 to 85% Porosity 75 to 80% Lignin 10 to 25% Surface area 30㎡ / g Pentoacid 5 to 10% size 0.5mm to 10mm

Microorganisms that decompose the organic matter contained in the solids are classified into bacteria, protozoa, and floc forming bacteria include Zoogloea ramigera and Sphearotilus natans as mainstream flocs. Achromobacter (Achromobacter), Alcaligenes (Bacillus), Bacillus (Flauobacterium), Siudomonas (Phseudomonas) and the like. Protozoa is a hybrid of aerobic microorganisms that do not require oxygen and oxygen-derived aerobic microorganisms that dominate the mainstream, ciliates are mainstream. The microbial floc propagated by the wood chip 56 digests and decomposes sludge mixed with organic matter in the wastewater. When the fluid containing the wastewater is introduced, the fluid passes through the particulate wood particles, Decomposition takes place by the microorganisms and generates a significant amount of heat, which enhances the activity of anaerobic microorganisms present in large amounts in particulate wood. The anaerobic microorganism is active at room temperature (20 ℃) digestive metabolism active, the temperature of the particulate wood particles is raised to about 70 ℃ to further enhance the activity of organic matter.

The principle of the wastewater treatment method by the particulate wood particles using the wood chip 56 is to treat wastewater biologically, aerobic microorganisms ingest carbohydrates and nitrogen compounds, carbohydrates intake oxygen to carbon dioxide and water It decomposes, removes carbon organic matter and nitrates using energy, and purifies by lowering biological oxygen demand. Anaerobic microorganisms absorb carbonic acid gas, methane gas, ammonia, hydrogen sulfide, etc. without oxygen supply and absorb and decompose macromolecular organic matter.

As a result, the aerobic microorganisms decompose organic matter in the wastewater, thereby removing the carbon organic matter in the wastewater.

Next, the fluid purified through the aeration unit 50 flows to the complex processing unit 60 through a pump (not shown).

The complex treatment unit 60 is a device for biologically and chemically purifying the first purified fluid through the aeration unit 50, and the solid preparation 62 for the advanced treatment of wastewater therein (hereinafter, simply the solid preparation). And (62). And the wood chip 66 are arranged.

The solid preparation 62 according to the present invention may exhibit a pellet form of a predetermined size, and is immersed in waste water in the advanced treatment step to remove nutrients such as nitrogen and phosphorus in water. In this case, the term `` advanced treatment '' refers to the final tertiary treatment in the three stages of general wastewater treatment, and the general wastewater treatment stage separates solids, fine suspended solids, oils and fats, and is 25% to 35% BOD. BOD 75-95% and suspended solids 70-90% by primary treatment (simple treatment) to remove 30 to 40% of the substance, activated sludge method, water spraying method, etc. It is divided into secondary treatment (advanced treatment) to remove and tertiary treatment to obtain high water quality by removing nutrients such as nitrogen (N) and phosphorus (P) in water, that is, advanced treatment.

Therefore, the solid preparation 62 according to the present invention serves to remove nutrients such as nitrogen (N), phosphorus (P) in the water by being immersed in the wastewater of the advanced treatment step, and the mesh is free of contact with the wastewater. (mesh) It can be placed in the casing 63 or the like and mounted in an aeration tank, and includes hydrated lime, illite, oyster shell, and activated carbon powder as main components to remove nutrients. At this time, if necessary, the aeration tank may be provided with a diffuser 61 for inducing contact between the wastewater and the solid preparation 62, and an airlift device may be provided for separating solids precipitated in the aeration tank. Aeration tanks, including engines and airlifts, are easily understood by those skilled in the art, and thus a detailed description thereof will be omitted.

Each component constituting the solid agent 62 will be described in more detail.

First, hydrated lime is a hydroxide of calcium (Ca) called calcium hydroxide, which is obtained by acting on water or steam (calcination of quicklime) on calcium oxide (CaO, quicklime). At this time, white powder is obtained by rapidly extinguishing quicklime, while hexagonal plate crystals are obtained when left in water. Therefore, in the latter case, the powder is used through a separate grinding operation. The slaked lime acts as an alkali supplement to remove phosphorus and to raise the pH of the waste water, together with the role of an adjuvant to enhance the flocculating component of the flocculant described later.

Next, the illite is a kind of clay mineral belonging to a monoclinic system, and generically refers to fine white mica. The illite is negatively charged in water (-2) and absorbs and decomposes organic matters such as heavy metals and algae through ion exchange, adsorption, and coprecipitation reaction, and the organic matters by radicals such as free radicals and OH- It causes oxidation and decomposition, and removes impurities in water through aggregation and precipitation of SiO2 and Ai2O3. In addition, the elite destroys the cell walls of algae to prevent recurrence, removes nutrients such as nitrogen (N) and phosphorus (P) and harmful heavy metals, and reduces the smell of treated water and sludge through deodorizing characteristics. When used together with hydrated lime, it acts as a flocculant with better sedimentation and dehydration properties.

Next, the oyster shell is what is called a shell, and is composed of 94% of calcium carbonate and 6% of other components such as gypsum. The oyster shell is used as a natural coagulant to purify the pH in the solid preparation according to the present invention, and to replace the aluminum flocculant. At this time, the oyster shell for the solid preparation 62 according to the present invention is characterized in that the high-temperature calcined through a special treatment process, specifically, after aging the oyster shell collected from the shore for about a year and washed to remove impurities Next, it is sufficiently baked at a high temperature of 700 ° C. or higher, and finely pulverized so as to have a diameter of 0.15 mm or less.

Next, activated carbon can be obtained by carbonizing coconut shell, coal, wood, etc. at high temperature, and finely pulverized to 325 mesh or less. At this time, the mesh refers to a title for grading the size of the particles (粒子). The activated carbon functions to adsorb and remove various soluble organic substances, odorous substances, harmful substances, and heavy metals through countless pores therein.

In addition, a certain amount of loess may be added to the solid preparation 62 according to the present invention. In addition to the role of adsorbing phosphorus (P) and purifying the water quality, slaked lime, illite, oyster shell, activated carbon powder It acts as a binder to maintain the shape of the pellets. For this purpose, ocher is filtered finely in the water to remove sand and then fine particles submerged in the water are used.

On the other hand, the solid preparation 62 according to the present invention can obtain the highest nutrient removal efficiency by adjusting the mixing ratio between the constituent materials, the results of the applicant's experiments, slaked lime, illite, high temperature calcined oyster It was found that the shell and the activated carbon powder were mixed at a ratio of 4: 3: 2: 1, and containing 20 wt% of ocher was most appropriate.

Next, the wood chips 66 are disposed inside the complex processing unit 60, and the wood chips 66 are formed of particles smaller than the wood chips 56 of the aeration unit 50. .

The fluid pumped from the aeration unit 50 is purified while passing through the solid preparation 62 and then moved downward, and once again while being passed through the wood chips 66 disposed on one side.

Here, when passing through the wood chip 66, the fluid is purified while flowing from the lower side to the upper side, thereby preventing the solid particles of the coarse particles from passing through.

Next, the fluid passing through the wood chip 66 flows to the bioreaction unit 70.

Here, the fluid purified by the complex processing unit 60 may flow through a pump (not shown), or a pipe (not shown) may be installed to flow naturally into the bioreaction unit 70.

The bioreaction unit 70 includes a bio tank 72 in which a wood chip 76 is stored, an diffuser 74 disposed inside the bio tank 72 to supply oxygen, and the bio tank 72. Is disposed and the outer tank 71 in which the fluid supplied from the complex processing unit 60 is stored, and the first pump 77 for supplying the fluid stored in the outer tank 71 to the bio tank 72; And a second pump 78 for supplying the purified fluid via the bio tank 72 to the filtration unit 80.

The wood chip 76 is preferably made of the same material as the wood chip 56 described above, but having a smaller thickness.

The bio tank 72 is filled with the wood chip 76 therein, the diffuser 74 is installed in the lower side. Thus, when the diffuser 74 is operated, oxygen is supplied to the wood chip 76 so that microorganisms inhabiting the wood chip 76 become more active and decompose organic matters of the supplied fluid.

Here, the fluid supplied from the complex processing unit 60 is stored in the lower portion of the outer tank 71, and the first pump 77 stores the fluid stored in the outer tank 71 in the bio tank 72. Pump up.

Then, the fluid supplied to the outer tank 71 passes through the wood chip 76, and the solid matter is decomposed, and the purified water falls to the lower portion.

Here, the place where the first pump 77 is disposed and the place where the second pump 78 is disposed are partitioned from each other so that the fluid supplied from the complex processing unit 60 may pass through the bio tank 72. Do not mix with passing fluid.

The second pump 78 pumps the fluid purified from the biotank 72 to the filtration unit 80.

Here, the first and second pumps 77 and 78 are respectively provided with a water level sensor is operated.

The filtration unit 80 is disposed granular activated carbon 82 for storing the fluid purified in the bio tank 72 and removing organic matter and pigments from the fluid.

Here, the granular activated carbon 82 is disposed in a mesh-shaped net and disposed, and a flow path is configured such that the fluid is filtered while flowing from the lower side to the upper side.

Next, the fluid purified in the filtration unit 80 is flowed and stored in the storage unit 90, the fluid movement from the filtration unit 80 to the storage unit 90 is a conduit (not shown) or pump (Not shown) or the like.

Thus, the fluid stored in the storage unit 90 is the storage unit 30, the flow rate adjusting unit 40, the aeration unit 50, the combined treatment unit 60, bioreaction unit 70, filtration unit 80 Purified by clean water, the water stored in the storage unit 90 is supplied to the toilet 10 through the pump (95).

As a result, the circulating flush toilet according to the present embodiment can not only purify the stored water but also reuse the toilet, so that the toilet can be continuously used even in a place without a separate water supply facility.

In other words, the present embodiment can circulate and reuse the water with a single water supply, and since no purified water is discharged to a river or a valley, sewage equipment is not required, and manure is not periodically collected.
