Description

Purification device {PURIFYING DEVICE}

The present invention relates to a purifier, and more particularly, to a purifier that aggregates and precipitates dirt in sewage using a flocculant powder.

Conventionally, as a purification apparatus, the system which removes the dirt and impurities in wastewater using a filter or microorganism is employ | adopted. On the other hand, recently, for example, zeolite-based coagulant powder has been developed. By adding and stirring this flocculant powder to wastewater, the wastewater in a wastewater can be aggregated and precipitated. As a result, it is expected that the purification process can be performed without using a filter or the like.

However, a purification apparatus with large scale and high efficiency using such a flocculant powder has not been developed. The present inventors have studied, and the following points are the subjects to consider. First, it is necessary to continuously add the flocculant powder to the sewage for efficient sewage treatment. Second, it is necessary to stir efficiently the sewage into which the flocculant powder is added. Third, it is necessary to efficiently agglomerate and precipitate the stirred wastewater.

Therefore, an object of the present invention is to solve the problem and to provide a purification device having good efficiency and large processing capacity.

The purifying apparatus of the present invention comprises a coagulant injector capable of continuously introducing coagulant powder, a stirrer for stirring coagulant continuously introduced from the coagulant injector and sewage introduced from the outside, and preliminary treatment by the coagulant injector and the agitator. It is characterized in that it has a sedimentation treatment tank for introducing the sewage to precipitate the aggregated sewage in the sewage.

Also, a purifier for purifying water stored in the water storage tank, a coagulant injector capable of continuously injecting coagulant powder, a stirrer continuously stirring the coagulant introduced from the coagulant injector, and water introduced from the water reservoir, the coagulant injector and The pretreated water pretreated by the stirrer is introduced, characterized in that it has a filtration tank for discharging the filtered water in which the aggregated dirt in the pretreated water is filtered to the water storage tank.

Next, this embodiment is described in detail, referring drawings. 1 shows the configuration of the entire system of the purification apparatus. FIG. 2 is a view of the precipitation treatment tank 30 of the purification apparatus of FIG. 1 viewed from the side.

This purification device is divided into three parts, a coagulant injector 10, a stirrer 20, and a precipitation treatment tank 30. The coagulant injector 10 is an agitation member made of, for example, an octagonal column, which is rotatably driven at the bottom of the accommodating part 11 and the bottom part of the accommodating powder 11 in the form of a mortar. And a coagulant powder dropping hole 13 is opened at the bottom of the housing portion 11 so that the coagulant powder forms the coagulant powder dropping hole 13 with the rotation of the stirring member 12. It is continuously put into the stirrer 20 installed below it. As the coagulant powder, for example, zeolite-based coagulant powder is suitable because of its high coagulation effect. However, according to the inventors' review, it is important to sufficiently agitate the coagulant powder and then stir it sufficiently to obtain a coagulation effect. .

Therefore, the stirrer 20 is a cylindrical 1st stirring vessel 21 (1st stirring part), and the 2nd stirring vessel 22 of the rectangular parallelepiped connected with the bottom part of this 1st stirring container 21 (2nd) Stirring section). The introduction pipe 19 of wastewater is connected to the side surface of the first stirring vessel 21. Moreover, four stirring plates 23 are continuously provided in the inner wall of a 2nd stirring container. Each stirring plate 23 is fixed to one inner wall, and is alternately attached between the inner walls of the opposite side so that the clearance which can fall without a waste water stagnates.

When the sewage pressurized from the introduction pipe 19 is introduced into the first stirring vessel 21, the sewage falls while forming a vortex along the inner wall of the first stirring vessel 21. In this vortex, the coagulant powder is continuously introduced from the coagulant injector 10 described above, so that the sewage and the coagulant powder are agitated, and the uppermost part of the second stirring vessel 22 is passed through the hole in the bottom of the first stirring vessel 21. Guided onto a stirring plate 23 installed in the.

The sewage containing the coagulant powder flows on the stirring plate 23, impinges on the inner wall of the second stirring vessel 22, falls on the lower stirring plate 23, and flows on the stirring plate 23. Repeat the collision with the inner wall of the opposite side. That is, by repeatedly impinging on the inner wall while the sewage containing the coagulant powder is accelerated, the sewage and the coagulant powder are further stirred to discharge the discharge pipe 25 from the sewage outlet 24 provided at the bottom of the second stirring vessel 22. It flows down into the sedimentation treatment tank 30 through.

The sedimentation treatment tank 30 is for sedimentation of the sewage in the sewage aggregated by the coagulant powder, but in addition, the diffuser 31 which supplies a plurality of oxygen bubbles to the sewage has a bottom of the sedimentation treatment tank 30. It is arrange | positioned according to a part. The diffuser 31 is provided with a plurality of diffuser holes, and generates a plurality of oxygen bubbles by introducing 95% or more of high-purity oxygen into the diffuser 31 from the oxygen generator 32 installed side by side in the sedimentation treatment tank 30. Can be.

As the oxygen generator 32, for example, an oxygen cylinder or a commercially available oxygen generator can be used. These oxygen bubbles promote oxidation and precipitation effects by giving oxidation action to the flocculant powder and the stirred sewage. In the present invention, since oxygen bubbles are generated, oxidizing action against bacteria in filthy water and the like is stronger than air containing 75% of nitrogen, and the aggregation and precipitation effects of the soil can be promoted more efficiently.

Moreover, the air contact tank 34 is provided in the position higher than the water surface 33 of the introduced wastewater, and the submersible pump 35 which pumps wastewater into this air contact tank 34 is provided. Sewage is pumped by the submersible pump 35 through the pipe 36 to the air contact tank 34. The sewage is continuously dropped into the sedimentation treatment tank 30 by overflowing the sewage from the air contact tank 34. Thereby, since the sewage falls to the water surface 33 of the sedimentation treatment tank 30 like a waterfall and generates bubbles, a lot of contact with air can be obtained.

In addition, the bottom of the sedimentation treatment tank 30 is provided with a settling groove 38 for sedimenting the aggregated and settled dirt, and a discharge pipe 39 is provided at the bottom of the settling groove 38. By opening the valve 40, dirt can be discharged to the outside. In addition, the sedimentation treatment tank 30 is provided with a discharge pipe 41 for discharging the supernatant water (cold water) after the condensation and sedimentation of the dirt, and discharges the purified supernatant water to the outside by opening the valve 42. Can be.

In the purification device of the above-described configuration, the diffuser 31 and the air contacting tank 34 are operated in a state in which a predetermined amount of sewage is stored in the sedimentation treatment tank 30 for about 24 hours via the stirrer 20. As a result, dirt is agglomerated and precipitated at the bottom of the precipitation treatment tank 30.

3 shows another system configuration of the purification device. In addition, about the component same as FIG. 1, the same code | symbol is attached | subjected and description is abbreviate | omitted. In this purification apparatus, the flocculant powder and the filthy water stirred by the stirrer 20 are introduced into the air contacting tank 34 provided below the inclination of the stirrer 20 through the discharge pipe 25. Then, the sewage overflows from the air contacting tank 34 and falls like a waterfall to the sedimentation treatment tank 30 adjacent to the lower side, so that the sewage and air come into contact with each other. As a result, unlike the system of FIG. 1, there is an advantage that the submersible pump 35 and the like can be eliminated.

In addition, the supernatant water from the septic tank 30 may be circulated by the stirrer 20 by providing the pipe 46 and the pump 47 which join the inlet pipe 19 of the stirrer 30. Thereby, the wastewater can be agitated again in the stirrer 20 to be introduced into the precipitation treatment tank 30 from the air contacting tank 34, and the dirt can be aggregated and precipitated again in this process. In this purification apparatus, it is not necessary to generate oxygen bubbles from the diffuser 31.

4 shows another system configuration of the purification apparatus. In addition, about the component same as FIG. 1, the same code | symbol is attached | subjected and description is abbreviate | omitted. This purification device purifies the water (sewage) stored in the reservoir 50. The reservoir 50 includes a pool, a pond, a lake, and the like. The water in the reservoir 50 is pumped up by the pump 52 through the pipe 51 and introduced into the stirrer 20 from the introduction pipe 19.

Then, the coagulant powder is continuously added to the stirrer 20 from the coagulant injector 10. Water and coagulant powder introduced into the stirrer 20 are stirred by the stirrer 20. The pretreated water pretreated by the stirrer 20 flows through the discharge pipe 25 of the stirrer 20 and is introduced into the filtration tank 60 provided below the inclination of the stirrer 20. The filtered water passed through the filtration tank 60 is discharged to the water storage tank 50. In this way, the water in the reservoir 50 is purified by circulating the inside of this purification apparatus for a predetermined time.

5 is a cross-sectional view showing the detailed structure of the filtration tank 60 described above. The filtration tank 60 basically filters the water introduced into the filtration tank 60 from below the filtration layers 66 and 71 through the upper side. The 1st filtration tank 61 and the 2nd filtration tank 63 are spaced apart by the 1st partition 62 installed standing up to predetermined height from the bottom part of the filtration tank 60. As shown in FIG. The inlet pipe 64 is attached to the side wall of the first filtration tank 61 and is connected to the discharge pipe 25 of the stirrer 20. Therefore, the pretreated water flows down into the discharge pipe 25 and is pressed to flow into the first filtration tank 61 from the introduction pipe 64. The first wire mesh 65 is attached to the inner wall of the first filtration tank 61 at a position higher than the introduction pipe 64, and the first filtration layer 66 is provided on the first wire mesh 65. . When the level of the pretreated water introduced into the first filtration tank 61 rises, the pretreated water normally passes upward from the bottom of the first filtration layer 66.

The first filtration layer 66 is composed of a layer of filter material, and it is suitable to laminate a predetermined thickness of particles having a large number of irregularities on the surface, such as finely crushed volcanic stone. The thickness is about 20 cm, for example. Soil in the coagulant powder and the stirred pretreatment water is agglomerated by the coagulant powder, and the agglomerate is deposited in the first filtration layer 66 to perform filtration of the water in the first stage.

The first filtration layer 66 is formed to a height slightly lower than the height of the first partition wall 62, and as a result of the pretreatment water passing through the first filtration layer 66 on the surface of the first filtration layer 66, The filtered water 67 rises. The filtered water 67 overflows from the discharge port 68 on the partition wall 62 and is introduced into the adjacent second filtration tank 63.

The 2nd partition 69 is provided in the 2nd filtration tank 62 to the middle of the depth, and the filtered water from the 1st filtration tank 61 descends once along one wall of this 2nd partition 69, Then, it rises along the other wall of the partition 69, and passes the 2nd filtration layer 71 from below to upward. The second filtration layer 71 is provided on the second wire mesh 70 provided on the second partition wall 69. Here, the second filtration layer 71 is configured similarly to the first filtration layer 66. Then, the filtered water that rises through the second filtration layer 71 upwards from below is overflowed from the discharge port 72 and discharged to the outside through the discharge pipe 73. Filtrate water from the first filtration tank 61 is filtered again by the second filtration tank 63 by the above mechanism.

In addition, a diffuser 74 generating a plurality of bubbles is provided below the first filtration layer 66 of the first filtration tank 61, and the bubbles are configured to contact the surface of the first filtration layer 66. have. The diffuser 74 is supplied with air from the outside. Thereby, the film | membrane which consists of dirt etc. which adhere to the surface of the 1st filtration layer 66 is always removed, and the filtration function is prevented from falling.

Moreover, the 1st discharge pipe 75 is provided in the bottom of the 1st filtration tank 61, and the sewage in the 1st filtration layer 61 is discharged | emitted by opening the 1st valve 76. FIG. In addition, similarly, a second discharge pipe 77 is provided at the bottom of the second filtration tank 63, and the sewage in the second filtration tank 63 can be discharged by opening the second valve 78. In addition, although the filtration of two stages is performed using the 1st filtration tank 61 and the 2nd filtration tank 63 in the above-mentioned embodiment, although the filtration capacity is inferior to this, it is also possible to use only the 1st filtration tank 61.

6 is a sectional view showing another detailed structure of the filtration tank. This filtration tank connects two filtration tanks 60 of FIG. 5 mentioned above. That is, the discharge pipe 73 of the filtration tank 60 is connected to the introduction pipe 64 of the following filtration tank 60 via the connection pipe 80. As shown in FIG. Thus, by connecting two or more filtration tanks 60, filtration capacity can be improved further.

Moreover, as another system of a purification apparatus, it is a purification apparatus which circulates water only through the filtration tank 60 of the said structure, and does not use the flocculant injector 10 and the stirrer 20. Even in the case of this purification apparatus, if it takes a long time, it is possible to fully purify water.

Next, the structure of the coagulant injector 10 described above will be described in more detail with reference to FIGS. 7 to 9. 7 is a top view of the coagulant injector 10, FIG. 8 is a cross-sectional view taken along the line A-A of FIG. 7, and FIG. 9 is a cross-sectional view taken along the line B-B of FIG. This coagulant injector 10 forms the shape of a mortar, and the stirring member 12 which consists of octagonal pillars is provided in the bottom part of the accommodating part 11 of the coagulant powder 100. The stirring member 12 is not limited to an octagonal column and may be a hexagonal column, a octagonal column, or a polygonal column, but according to the experiments of the present inventors, an octagonal column is suitable.

The flocculant powder 100 is thrown in from above the storage portion 11. The coagulant powder dropping hole 13 is opened in the bottom part of the accommodating part 11, and the coagulant powder was continuously provided below the coagulant powder dropping hole 13 with rotation of the stirring member 12, It is injected into 20. Here, the stirring member 12 which consists of octagonal pillars is attached to the rotating shaft 14, and several stirring member 15 is attached to the rotating shaft 14 further. The stirring member 15 is preferably L-shaped or loop-shaped. Since the flocculant powder stored in the bottom part is stirred by rotating the stirring member 12 and the stirring member 15, the so-called bridge | bridging generate | occur | produces and the fault which prevents it from being able to continuously drop the flocculant powder 100 is prevented.

The rotary shaft 14 is taken out to the outside through the guide tube 16 provided on the side of the housing 11 and is driven to rotate by attaching the rotary shaft of the motor to the distal end thereof or by attaching the manual handle.

In addition, a heater 17 for heating and drying the coagulant powder 100 is attached to the periphery of the coagulant powder dropping hole 13 outside the main body. The reason for installing the heater 17 is that when the coagulant injector 10 is installed on the agitator 20 described above, the coagulant powder 100 is moist and viscous due to the water evaporated from the agitator 20. This is because the coagulant powder dropping hole 13 is clogged or the coagulation effect of the coagulant powder 100 itself is lost.

Next, the structure of the agitator 20 described above will be described in more detail with reference to FIGS. 10 and 11. 10 is a top view of the stirrer 20, and FIG. 11 is a cross-sectional view taken along the line A-A of FIG. As described above, the stirrer 20 has a cylindrical first stirring vessel 21 (first stirring portion) and a rectangular parallelepiped second stirring vessel 22 connected to the bottom of the first stirring vessel 21. ) (Second stirring part). Here, the inflow pipe 19 of wastewater is joined to the side surface of the 1st stirring vessel 21 so that wastewater may be introduce | transduced from the direction along the circumference of the 1st stirring vessel 21 as shown in FIG. Thereby, wastewater becomes a vortex in the 1st stirring container 21, and it is stirred efficiently.

In addition, the stirring plate 23 is inclined and attached to the inner wall of the 2nd stirring container 22 inclined downward. Thereby, the sewage containing the flocculant powder from the 1st stirring vessel 21 accelerates and flows on this stirring plate 23, and impinges on the inner wall of the 2nd stirring vessel 22 momentarily, and the below stirring plate 23 is carried out. It flows in and falls, and it accelerates and flows on this stirring plate 23, and repeatedly collides with the inner wall of an opposite side favorably. Thereby, stirring can be performed more efficiently. In addition, the number of stirring plates 23 is not limited to four, It can increase or decrease suitably according to the processing capability of a purification apparatus.

The purification apparatus of the present invention efficiently and largely separates various wastewaters such as wastewater from a livestock center, various industrial wastewater, drainage from homes and stores, toilet drainage, livestock manure, or ponds and lakes. It can be purified.

In particular, according to an experiment conducted by the present inventors, in regard to the wastewater from the livestock center, water treated in a conventional purification apparatus has been treated with a purification apparatus of the present invention for the occurrence of "waste" or odor after one week after treatment. It was confirmed that water did not show occurrence of "dross," and was colorless and transparent, and no odor was generated.
