Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for regenerating a resource of liquid wastes and a concentrated metabolic material produced from the apparatus,

The present invention relates to an apparatus for regenerating a resource of a liquid waste using an aeration tank and a concentrated metabolite thereof. More particularly, the present invention relates to an apparatus for regenerating a resource of a liquid waste and a concentrated metabolite thereof capable of producing liquid fertilizer by treating liquid waste.

In recent years, environmental pollution caused by food, landfill leachate, manure, and animal waste has become a big social problem, and development of treatment technology has been a problem.

As a general method for purifying and treating liquid organic wastes such as animal wastes, which are generally known, there are various methods such as an activated sludge method, a long-term method, a BMW method, a contact oxidation method and a flesh-feeding method, which are imported from Japan. There is provided a treatment method for the microbial bacteria to grow and cultivate so that the microbes decompose the organic matter. The method includes aeration tank for removing suspended solids flowing into the wastewater from the primary settling tank and maintaining a constant dissolved oxygen concentration for culturing aerobic microbes, Sedimentation tank, etc., it is disadvantageous in that the structure for treating wastewater is enlarged, the treatment time is long, and the treatment structure is complicated.

In addition, in the biological treatment method of waste water by microorganisms, the microorganism must be cultivated for a certain period of time in a certain volume, and the microorganism which is cultured and propagated is treated as a process of decomposing, fermenting and oxidizing the organic matter dissolved in the waste water There is a problem that ammonia, hydrogen sulfide, and methyl mercaptan generated in the process are badly generated by bad smell and that the removal efficiency of nutrients such as nitrogen and phosphorus is low, thereby causing eutrophication.

Due to such a problem, in order to treat livestock waste discharged from organic wastes, especially farmhouses and the like, feces are poured into the pits and decomposed spontaneously, or purified by a conventional purifier or the like to be discharged to rivers or the like, Has been commonly used.

However, natural decomposition by the pit causes groundwater contamination. In the case of the method of discharging the purified water, which has been purified by the conventional purification apparatus, to the river, it takes a long time to purify the discharged water, The untreated wastewater was discharged due to the hall of the management station of the apparatus, and the wastewater was discharged due to unauthorized discharge of wastewater.

In particular, the BMW construction method (Japanese patent No. 2504364) for the production of liquid fertilizer is complicated and takes 150 days to produce the final product. Inefficiency of the treatment device causes a lot of initial construction costs and the inefficiency of the aeration method .

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for reducing the nitrogen and phosphorus that cause eutrophication and improving the purification efficiency of liquid wastes, The present invention provides a device for regenerating a resource of a liquid waste and a concentrated metabolite thereof.

It is another object of the present invention to provide an apparatus for regenerating a liquid waste, which improves the structure of the aeration tank, thereby reducing the manufacturing and maintenance costs and improving the purification efficiency.

FIG. 2 is a partially cutaway perspective view showing an aeration tank in a treatment apparatus according to the present invention, and FIG. 6 is a cross-sectional view of the processing apparatus according to the present invention, FIG. 1 is a schematic view showing a resource recycling system of a liquid waste including

According to the above-mentioned drawings, the present invention is characterized in that the present invention comprises a storage tank (10) into which raw wastewater such as toilet, livestock wastewater, factory wastewater, and waste leachate flows, and a clogged material such as vinyl or plastic contained in wastewater in the storage tank A circulating reaction tank 40 for removing nitrogen and phosphorus by maintaining the aerobic, anaerobic and anaerobic conditions by separating and aeration of the solid material while the wastewater flowing through the screen tank 20 and the screen tank 20 is retained, A sedimentation metering tank 30 disposed between the screen tank 20 and the circulation tank 40 for measuring the wastewater discharged into the circulation tank 40 and a primary metering tank 30 for metering the primary treated water passing through the circulation tank 40 Aeration tanks 50a, 50b, 50c, and 50d for aeration, and a discharge tank 60 for precipitating and discharging treated water through an aeration tank.

The screen trough 20 is provided with a screen net 21 and the screen net 21 serves to separate the foreign matter and to crush the solids such as manure contained in the raw wastewater to the mesh size of the screen .

The settling metering tank 30 is installed vertically in a staggered manner so that the inflow amount of the wastewater fed into the circulation reaction tank 40 is kept constant and flows out through the connection pipe of the screen tank 20 The wastewater is bumped against the blocking plate 31 and is once decelerated so that it can be introduced into the circulation reaction tank 40 at a constant flow rate. The wastewater is connected to the storage tank 10 by a bypass pipe, and the wastewater other than the amount of the circulating reaction tank 40 is returned to the storage tank 10.

The circulation reaction tank 40 is connected to the precipitation metering tank 30 to allow the wastewater discharged from the precipitation metering tank 30 to flow through the upper portion and to maintain the aerobic, anaerobic and anoxic conditions for efficient removal of nitrogen and phosphorus An air lift device (not shown) for discharging excess sludge deposited on the lower side is installed.

As shown in FIG. 3, the apparatus is installed in one tank 70, and partition walls are vertically installed in the tank 70 to divide each tank, and a wall pipe 71 is installed The first aeration tank 50a, the second aeration tank 50b, the third aeration tank 50c, the second aeration tank 50b, and the third aeration tank 50c, A fourth aeration tank 50d, and a discharge tank 60 are sequentially installed.

The number of the aeration tanks 50a, 50b, 50c and 50d may be set to be smaller or larger than that in the embodiment according to the characteristics of the organic waste solution. The greater the number of aeration tanks, the higher the purification rate of the waste water. It is possible to obtain a treated water having enough active microorganisms and nutrients necessary for the plant to be usable as a manure with 2 to 5, more preferably 4, groups because of economic efficiency and the like.

According to an embodiment of the present invention, the aeration tank has a structure in which a contact material 51 for supporting a microorganism for decomposing liquid waste therein is charged.

The contact material 51 may be directly filled into the aeration tank. Alternatively, a separate lattice structure (not shown) filled with the contact material 51 may be provided at a predetermined position in the aeration tank.

In addition, an aeration unit for aeration treatment of wastewater is installed in the circulation reaction tank 40 and the aeration tanks 50a, 50b, 50c, and 50d.

First, the aeration unit installed vertically in the circulation reaction tank 40 includes a breather 41 formed vertically inside the circulation reaction tank 40 and formed with an inflow hole 42 through which wastewater flows into the bottom of the circulation reaction tank 40, An air distributor 80 installed at the bottom of the wide tube 41 to generate air bubbles by distributing the air into the inside of the tube and a circulating reaction tank 40 which is formed along the outer peripheral surface of the upper tube 41, A bubble introducing pipe 44 connected to the upper end of the bore tube 41 and extending outward to return the bubble generated in the circulating reaction tank 40 to the circulating reaction tank 40; ).

The inflow hole 42 is formed at a predetermined distance from the bottom of the circulation reaction tank 40 because the sludge layer is deposited on the bottom of the circulation reaction tank 40 to a predetermined thickness, Since the holes 42 are exposed on the sludge layer, the wastewater can flow smoothly.

The sludge layer, which is formed at a constant thickness by the solid matter, efficiently removes nitrogen and phosphorus while maintaining aerobic, anaerobic and anaerobic conditions.

The air distributor 80 is connected to an air supply pipe 81 to be blown into a lower portion of the wide pipe 41 through an upper portion of the wide pipe 41, And a blower 82 for generating the air.

This arrangement simplifies the installation structure of the air disperser 80. The air supply pipe 81 is installed downward through the upper space of each of the open tanks so that the bottom of each of the circulation tanks 40, It is unnecessary to install the air supply pipe and each of the air supply pipes and to maintain the airtightness in comparison with the conventional structure in which the air supply pipe is installed through the air supply pipe.

In the meantime, according to the present invention, the wastewater flows into the waste pipe (41) through the inflow hole (42) and causes a rotating current in the circulation reaction tank (40) The wastewater inflow pipe 45 is connected to each of the inflow holes 42 and the end of the inflow pipe 45 is bent at right angles in a clockwise or counterclockwise direction with respect to a horizontal plane.

Preferably, as shown in FIG. 4, four inflow holes 42 are formed at 90-degree intervals along the outer circumferential surface of the wide branch pipe 41, and each inflow hole 42 is bent at right angles The inflow pipe 45 curved in an arc shape is arranged in a clockwise or counterclockwise direction to be connected and installed.

Therefore, in the process of flowing the wastewater into the wicket 41 through the inflow pipe 45, a return current toward the inlet side of the inflow pipe 45 is generated in the circulation reaction tank 40, The inflow of wastewater to be treated is accelerated, the inflow of sludge is smooth, and the aeration efficiency can be increased.

As shown in FIG. 1, the width of the wastewater is set so as to be equal to or smaller than that of the width of the wastewater (40) 50b, 50c, and 50d and the inflow pipe 45 provided in the inflow hole 42 are located close to the bottom surface of the aeration tanks 50a, 50b, 50c, and 50d, And a return pipe 46 extending to the upper part of the circulation reaction tank are provided to dispense the aerated foam to the immediately preceding tank.

On the other hand, as the amount of pollutants in the treated water gradually decreases as the process proceeds from the first aeration tank 50a to the fourth aeration tank 50b, it is necessary to increase the treatment amount of the pollutant from the fourth aeration tank to the first aeration tank.

To this end, the treatment apparatus of the present invention has a structure in which the return pipes 46 of the aeration tanks 50a, 50b, 50c, and 50d are relatively different in height from the bottom surface of the aeration tanks, .

In other words, the height of the return pipe provided in the sprue tube of the second aeration tank 50b is higher than the height of the return pipe 46 provided in the sprue tube of the first aeration tank 50a, The height of the return pipe provided at the bottom of the third aeration tank 50c is higher than the height of the installed return pipe and the height of the return pipe is raised in this way to increase the height of the return pipe installed at the bottom of the fourth aeration tank 50d Has the highest structure.

By setting the difference in height of the return pipe 46 in this manner, the time required for the aeration process in the aeration tanks 50a, 50b, 50c and 50d to be discharged through the return pipe 46 to the immediately preceding tank is made different by the height of the return pipe (The lower the height of the return pipe, the faster the treatment time). This difference in treatment time results in an improvement in the efficiency of the pollutant treatment. This will be described later.

Further, each of the width pipes 41 is connected to a separate gas discharge pipe 47 at the upper end thereof to discharge gas generated during the wastewater aeration.

The apparatus has a structure in which an air supply pipe 81 connected to the air disperser 80 is installed through the inside of the gas discharge pipe 47 so that the gas discharge pipe 47 serves as a support for the air supply pipe 81 The mounting force of the air supply pipe 81 can be increased and the air distributor 80 mounted at the lower end of the air supply pipe 81 can secure the support rigidity without a separate supporting structure.

The air distributor 80 installed in each of the width base portions is connected to the end of the air supply pipe 81 installed vertically downward through the wide pipe 41 to disperse the air. As shown in FIG. 5, The air discharged through the holes 84 formed at the lower end of the air supply pipe 81 flows through the fine pores of the porous block 83 to form a width So that the wastewater can be augmented while being dispersed into the engine 41.

The porous block 83 is connected to the air supply pipe 81 by being tightened by a plate 85 which is in close contact with the upper and lower ends and a nut 86 which is fastened to the male screw formed on the air supply pipe 81 and presses the upper plate 85, do.

The discharge tank 60 is for supplying and discharging the final discharge water through the flow pipe 71 connected to the upper part of the aeration tank 50. A diaphragm 63 is installed in the center of the discharge tank 60, The lower end of the diaphragm 63 forms a flow passage 64 having a certain distance from the bottom of the discharge tank 60 so that the treated water can be circulated, And a discharge pipe 65 for discharging the finally treated liquid is installed at the upper end of the discharge part 62 side.

The treated water finally treated in the aeration tank 50 flows into the inflow portion 61 of the discharge tank divided by the diaphragm 63 and exits to the discharge portion 62 only through the flow path 64 on the bottom surface, 71 can be prevented from being discharged directly from the discharge tank (60).

On the other hand, regarding the number of the breechbreakers 41 installed in the circulation tank 40 or the aeration basins 50, the number of the breezeways 41 is not limited to one, and the size of the tank, the amount of the raw wastewater inflow, It is possible to install two or more structures. FIG. 6 illustrates that two circulation reactors are installed in the circulation reaction tank and the aeration tank, respectively.

It is natural that the efficiency of removing pollutants can be increased by increasing the number of the blowing units and arranging them in proper positions in each tank.

The operation of the processing apparatus according to one embodiment of the present invention will be described below.

The treatment apparatus of the present invention is characterized in that the organic waste liquid such as manure, livestock wastewater, and waste leachate is received from the precipitation metering tank 30 into the circulation tank 40 and advanced to each aeration tank 50, Since the bubble containing the organic matter generated by aeration in the breech block 41 installed in the aeration tank 50a, 50b, 50c, and 50d is circulated back to the immediately preceding tank in the tank to increase the decomposition rate of the biological treatment in the aerobic state, The solid organics present in the suspended wastewater in the waste water treatment tank 50 can be automatically and continuously removed as early as possible to finally produce an excess liquid having a high dissolved oxygen ratio.

The raw wastewater collected in the storage tank 10 flows into the upper portion of the screen tank 20 through the original wastewater supply pipe and passes through the screen net 21 installed in the screen tank 20 to be contained in rough and large debris, The debris such as waste vinyl is firstly filtered and crushed to a size as small as the mesh size of the screen net.

The wastewater that has passed through the screen net 21 is sent to the settling metering tank 30 through the feed pipe in accordance with the operation of the pump 22. The settling metering tank 30 supplies a predetermined amount of wastewater to the circulation tank 40, And the rest is returned to the storage tank 10 through the bypass pipe.

Thus, the wastewater flows into the upper portion of the circulation reaction tank 40 and is filled with a certain water level in the circulation reaction tank 40. The sludge contained in the wastewater is slowly submerged in the bottom of the circulation reaction tank 40, Is discharged to a separate sludge concentration tank (not shown) through a sludge discharge pipe 48 installed under the circulation reaction tank 40 in accordance with the operation of an air lift pump (not shown).

The wastewater in the circulation reaction tank 40 is introduced into the waste pipe 41 through the inflow hole 42 formed at the lower end of the waste pipe 41 by the aeration of the air distributor 80 located at the lower end of the waste pipe 41. [ And is then aeration.

That is, when the blower 82 is driven, air is supplied to the air supply pipe 81, and air is dispersed at the bottom of the blower 41 through the air distributor 80 connected to the lower end of the air supply pipe 81 do.

Accordingly, the air is dispersed through the holes formed in the porous block of the air disperser 80, so that minute bubbles are generated inside the breech block 41, and the organic bubbles of the wastewater are adhered to the surfaces of the fine bubbles.

Organic dirt is adhered to the surface of the foam produced by the aeration and this foam rises to the top of the extrusion pipe 41 and flows through the foam feed pipe 44 installed on the top of the extrusion pipe 41, Lt; / RTI > At this time, a part of the foam is discharged through the dispersion hole 43 formed in the upper portion of the expansion pipe 41 and dispersed to the circulation reaction tank 40.

The wastewater is rotated in one direction in the circulation reaction tank 40 by the inflow pipe 45 provided in the inflow hole 42 of the expansion pipe 41, The inlet of the inflow pipe 45 is directed to the tangential direction of the blowing pipe 41 so that the wastewater flows into the tangential direction of the blowing pipe 41 The wastewater in the circulation reaction tank 40 generates a return current toward the inlet side of the inflow pipe 45.

Therefore, the flow of the wastewater treated by the aeration is accelerated by the rotating current, and the inflow of the sludge is smooth.

On the other hand, the supernatant of the circulating reaction tank 40 is sent to the first aeration tank 50a through the overflow pipe installed in the partition wall, and is aerated again in the breeze tube 41 provided in the first aeration tank 50a.

The bubbles which have been aerated in the breeze 41 of the first aeration tank 50a and have risen to the top of the breeze 41 are introduced into the circulation tank 40 immediately preceding the breech line 46 installed on the top of the breeze 41 And supplied again.

The second aeration tank 50b, the third aeration tank 50c and the fourth aeration tank 50d are also aeration-treated in the same manner as the first aeration tank 50a, Circulates the wastewater treated by the aeration tank 50 immediately before the aeration tank 46 through the return pipe 46.

In addition, the gas generated in the wastewater aeration exits through the gas exhaust pipe 47 connected to the upper pipe 41 and the upper pipe.

Here, since the height of the return pipe 46 provided at the bottom of the first aeration tank 50a is lower than that of the other return pipes, the treated water adhering the pollutants in the first aeration tank 50a is supplied to the circulation tank 40 And it is possible to treat a relatively large amount of contaminants in the first aeration tank 50a as compared with the other aeration tanks 50b, 50c and 50d.

Accordingly, although the polluted matter is contained in the treated water in the first aeration tank 50a as compared with the contaminated matter content of the treated water flowing into the other aeration tanks 50b, 50c and 50d, Processing can be performed.

This operation also proceeds in the second aeration tank 50b, the third aeration tank 50c and the fourth aeration tank 50d, that is, the processing time corresponding to the height difference of the return pipe 46 is increased, The treatment operation can be performed in accordance with the amount of contaminants contained in the water, thereby maximizing the aeration efficiency.

In the aeration tank 50a, 50b, 50c, and 50d, the aerobic microorganism decomposes simultaneously with the wastewater aeration process.

The microorganisms attached to the contact medium (51) ingest some of the substances contained in the treated water to form new cells, and some of them are consumed as energy for microbial activity. In addition, other biodegradable materials are hydrolyzed into low molecular weight substances that are easier to ingest by the extracellular secretions of microorganisms, and are hydrolyzed into organic or organic ammonium ions or soluble phosphorus.

The final treated water having passed through the fourth aeration tank 50d is sent to the treated water inflow portion 61 of the discharge tank 60 through the upper side flow pipe 71, (64) to the treated water discharge portion (62) and discharged through the discharge pipe (65) provided on the treated water discharge portion side.

The final treated water thus discharged through the discharge pipe 65 is supplied as a concentrated metabolite through the multi-stage aeration tank 50, so that sufficient dissolved oxygen is obtained as shown in Table 1, and thus, it is useful as a high level liquid.
