Abstract

The present invention relates to a sewage treatment system which enables food waste and sludge contained in sewage to be automatically filtered off in a collecting well of a house, shopping district, factory, road, and the like, before being discharged, so as to prevent the contamination of a river or the like. The sewage treatment system of the present invention automatically senses the backflow of sewage during the rainy season to preemptively prevent damage caused by flooding, and treats sludge deposited in the collecting well through compulsory suction to enable the collecting well to be easily cleaned. The sewage treatment system of the present invention separately collects sewage and food waste even when the sewage and food waste are simultaneously dumped, and automatically filters off food waste from the sewage, to thereby prevent structural problems caused by a combined sewer system in which rainwater and sewage are mixed.

Description

Sewage treatment system

The present invention can prevent contamination of rivers and the like by automatically filtering and discharge food waste and sludge contained in the sewage in the sump, such as homes, malls, factories and roads, and automatically detects the sewage backflow during the rainy season. It is possible to prevent flood damage in advance, and it is possible to treat sludge deposited in the sump by forced suction, so it is easy to clean the sump and automatically filter after segregation even if the sewage and crushed food waste are discharged at the same time. The present invention relates to a sewage treatment system that can solve a structural problem by combining conduits where rainwater and sewage are mixed.

In recent years, domestic sewage and industrial wastewater are increasing day by day, and these sewage and wastewater include sludge such as suspended solids and earth and sand. The sludge is loaded and decayed for a long time in the sump or sewage pipe to cause bad smell may cause people discomfort.

Thus, the sludge accumulated in the sump or sewage pipe is treated through the manpower. The conventional technique for solving this problem is to use a dredge suction vehicle. Specifically, dragging the hose through the manpower to enter the sump or sewer pipe to suck the sludge, or to carry out the dredging operation using a small skid rotor in the middle of the diesel construction. However, the equipment is also difficult to work with due to the large amount of water flowing in the sump or sewage pipe, and there is a danger of poisonous gas (ammonia) and soot caused by decay.

In addition, when there is a rainy area or a heavy rain, living sewage flowing in the sewage pipe due to a large amount of rain and sludge such as suspended solids or earth and sand loaded in the sewage easily flow back through the sump.

To prevent such damages, it is necessary to install a backflow prevention facility for sewage pipes and water collection facilities such as each home or a shopping mall, and preventive inspection such as thorough water management. There is a problem that can not be installed.

A control groove having fixed contacts 211 and 221 electrically connected to the control unit 700 and slide holes 212 and 222. Control rods (214, 224) are formed (213, 223), and slide rods (215, 225) through which the slide holes (212, 222) and the sliding contacts (215, 225) that can contact the fixed contact (211, 221) is formed at one end (216, 226) and buoyancy holes (217, 227) that is caught in the control grooves (213, 223) when the other end of the slide rods (216, 226).

4A and 4B, the buoyancy balls 217 and 227 rise as the sewage level rises, and the slide rods 216 and 226 integrally interlock with the buoyancy holes 217 and 227 are slide holes. A fixed contact (211, 221) is electrically connected to the control unit 700 as the rise in the inner periphery of (212, 222) and the rise is controlled by the control grooves (213, 223) of the control panel (214, 224). The slide contacts 215 and 225 are separated from each other and the ON signal is output to the controller 700 based on such separation. When the ON signal is output to the control unit 700, as shown in FIG. 7, the S / W input module 710 of the control unit 700 receives an ON signal to the suction pump 300 through the power supply module 720. It will supply power.

In addition, the control unit 700 further includes a manual operation S / W 730 for arbitrarily driving the suction pump 300 so that a user or an administrator is not an input signal of the buoyancy S / W 200. The operation of the suction pump 300 can be controlled.

Meanwhile, in the present invention, an example in which two buoyant S / Ws 200 are provided is provided. The first buoyant S / W is formed on the inlet pipe 140 in the first chamber 105. 210 and a second buoyancy S / W 220 configured at the upper portion of the water inlet pipe 140 in the third chamber 130 is shown. The first buoyancy S / W 210 is attached to the inner circumference of the sump 100 to the upper portion of the inlet pipe 140, the second buoyancy S / W 220 is the drain pipe 150 Attached to the inner circumference of the sump (100) to the top of each), each attachment means is omitted as a known technique.

The first buoyancy S / W 210 is installed on the upper portion of the inlet pipe 140, but the water level for outputting the ON signal detected by the first buoyancy S / W 210 is the inlet pipe 140 If higher than), the sewage is likely to cause backflow into the inlet pipe 140, so that the first suction pump 310 is forced to discharge the sewage when the water level reaches the inflow pipe 140 so that the sewage may be Inflow pipe 140 to prevent backflow. In addition, it is reasonable that the first buoyancy S / W 210 is configured to be lower than the second buoyancy S / W 220, which is the second buoyancy S / W 220 will be described later The second suction pump when the inflow of sewage, such as when the secondary or rainy season in conjunction with the second suction pump 320 exceeds the suction amount by the first suction pump 310 interlocked with the first buoyancy S / W 210 To operate 320.

In addition, according to the present invention, as the buoyancy S / W 200 is provided with two examples, the case of the suction pump 300 is also provided with an example in which two are configured to interwork therewith, one of which is the second chamber. The first buoyancy S / W 210 and the control unit 700, which is configured on the bottom surface of the 120 is connected to the filtration column 600 and the first discharge pipe 311 to be described below The first suction pump 310. The first suction pump 310 is configured to suck the sewage including the sludge stored in the second chamber 120 under the control of the control unit 700 based on the ON signal of the first buoyancy S / W (210). The sewage sucked in this way is to be introduced into the sludge accommodating part 400 through the sludge outflow pipe 621 via the filtration column 600. If sewage is stored in the sump 100 above a certain level based on the interlocking of the first buoyant S / W 210 and the first suction pump 310, the sewage is forced out to the sludge accommodating part 400. By discharging the sewage treated with the sludge from the sludge accommodating part 400, it is possible to prevent the overflow of sewage, as well as to prevent decay and odor by sludge deposition.

The other is configured on the bottom surface of the second chamber 130 is interlocked by the second buoyancy S / W 220 and the control unit 700, the water collecting well 100 by the second discharge pipe 321 The second suction pump 320 is connected to the drain pipe 150 from the outside. In the case of the second suction pump 320, the sewage including the sludge stored in the third chamber 130 is controlled under the control of the control unit 700 based on the ON signal of the second buoyancy S / W 220. The sewage sucked in this way is configured to be bypassed by the second discharge pipe 321 to the drain pipe 150 from the outside of the sump well 100. When the sewage is above the water level detected by the first buoyancy S / W 210 based on the interlocking of the second buoyancy S / W 220 and the second suction pump 320. That is, when the forced suction amount of sewage which can be treated by the first suction pump 310 is exceeded, the second suction pump 320 may be operated at the same time to increase the treatment efficiency of the overflowed sewage. In addition, the configuration of the first suction pump 310 and the second suction pump 320 in such a way that one of the suction pump can be used to assist the other suction pump in case of failure so that the forced discharge of sewage is not stopped. For sake.

Meanwhile, in the present invention, a filtration column 600 having a through hole 611 communicating with the drain pipe 150 is formed in the third chamber 130.

The filter column 600 will be described in more detail. The filtration column 600 is configured between the first suction pump 210 and the sludge accommodating part 400 from the first suction pump 210. The branched first discharge pipe 311 is connected to the upper surface 610, and the sludge discharge pipe 621 is branched from the side surface 620 is connected to the sludge receiving portion 400. The sludge outflow pipe 621 is preferably located at the upper end than the through-hole 611. In addition, the filtration column 600 has a plurality of flow holes 631 formed at a lower end of the lower surface 630 and the side surface 620 of the filter column 600, and the sewage flows into the flow hole 631, and the through hole 611 is formed. Sewage is discharged to the drain pipe 150 through the), and the sludge caught in the filter medium 660 to be described below to the flow hole 631 is discharged to the third chamber (130).

A pressure plate 640 is formed at an upper portion of the filtration column 600, and the pressure plate 640 has the same shape as that of the inner circumference of the filtration column 600. The pressure plate 640 is not limited to the material, but it is reasonable to use an elastic water-tight material such as silicon, because the water tightness should be formed between the inner circumference of the pressure plate 640 and the filter column 600. In addition, the pressing plate 640 further includes a screen 641 protruding from both sides of the lower surface. That is, the pair of screens 641 are in contact with the inner circumference of the filtration column 600 to open and close the through hole 611 as the pressing plate 640 slides up and down. Composing the screen 641 in pairs is to prevent the up and down slide of the pressure plate 640 due to the action of the eccentric.

An air tube 670 is formed between the screens 641 in the shape of a circular wrinkle tube at a lower portion of the pressure plate 640, and the pressure plate 640 is separated from the first discharge pipe 311 by the air tube 670. The air is injected downward from the air tube 670 by the water pressure caused by the incoming sewage, and the injected air pressurizes the water suction material 650 to absorb water and air sucked into the water suction material 650. The sediment is discharged to the lower end of the third chamber 130, and the sewage sucked by the first suction pump 310 flows out into the sludge accommodating part 400 after the sediment is discharged to the filter medium 660. It is to make resilience occur.

The water suction member 650 is formed below the air tube 670, and the water suction member 650 flows into the filter medium 660 to filter the sewage filtered primarily, and drain pipe 150 to the secondary. As the pressure plate 640 slides downward in a state in which water is accumulated by sewage, the air tube 650 is compressed and the compressed air pressure is compressed to the water suction member 650. Moisture and air pressure accumulated in the water suction member 650 are discharged to the filter media 660 to allow foreign substances such as sludge deposited between the filter media 660 to flow out to the outside through the flow hole 631. ) Cleaning is possible.

The filter medium 660 is disposed between the lower portion of the water suction member 650 and the lower surface 630 of the filter column 600. The filter medium 660 is not limited to the material, and is configured to filter foreign substances such as sludge from the sewage introduced through the flow hole 631 and discharge them to the drain pipe 150 through the water suction material 650.

In addition, the present invention further comprises a partition plate 680 in which a plurality of communication holes 681 are formed between the air tube 670 and the water suction member 650 and between the water suction member 650 and the filter medium 660. . Based on the partition plate 680, the air and water are freely interlocked between the air tube 670 and the water suction member 650 and between the water suction member 650 and the filter medium 660 to partition the respective components. will be.

Referring to FIGS. 5A and 5B, the operation of the filtration column 600 according to one embodiment of the present invention will be described. First, when the water level of the sewage stored in the sump 100 is low, the flow of the sewage W1 is illustrated in FIGS. As shown in 5a, the second chamber 120 flows from the second chamber 120 to the third chamber 130, and the sewage of the third chamber 130 passes through the filter medium 660 through the flow hole 631. As the sludge is filtered through, the sludge is secondarily filtered by the water absorbing material 650 and discharged to the drain pipe 150 through the through hole 611 so that the sludge filtered sewage is discharged to the storage tank 500. will be.

Also, as shown in FIGS. 1 and 5B, when the water level of the sewage is high, the flow of the sewage (W2) is operated by the first suction pump 310 by the first buoyancy S / W 210 to operate the first chamber 120. Inhalation of the sewage) is to let the sewage flows out from the upper surface 610 of the filter column 600 through the first discharge pipe 311, the discharge of the sewage pressurizing the pressure plate 640 to the pressure plate At the same time, the air tube 670 is contracted and the air tube 670 is contracted to pressurize the water suction member 650 while generating air pressure, and at the same time, the screen 641 of the pressure plate 640 is pressed. The through-hole 611 is closed to prevent the water in the water absorbing material 650 from leaking into the drain pipe 150 and reducing the pressure loss so that the air pressure and the water pressure act only downward. As the water suction member 650 is pressurized, the water and air pressure of the water suction member 650 flows out to the filter medium 660, and the water and air pressure that flows out flows through the sludge deposited in the filter medium 660. To clean the filter medium 660 by flowing out through the third chamber 130, and the downward slide and pressurization by the water pressure slides the pressure plate 640 to the bottom of the sludge outflow pipe 621. When the sewage introduced into the first discharge pipe 311 is discharged to the sludge receiving unit 400 through the sludge discharge pipe 621, the pressure plate 640 by the restoring force of the water suction material 650 and the air tube 670 ) Slides upward, and at the same time, the screen 641 opens the through hole 611 to reactivate the sewage flow W1 as shown in FIGS. 1 and 5A. That is, the action of the filtration column 600 in Figure 5b is to discharge the sewage with the raised water level to the sludge accommodating unit 400 to prevent the overflow of the sewage, backflow and at the same time to clean the sludge deposited filter medium 660 Will be done.

Meanwhile, the sludge accommodating part 400, which is one configuration of the present invention, includes a housing 410 and a filter barrel 420 disposed in the housing 410 as shown in FIG. 6.

The housing 410 allows the sludge outflow pipe 621 to penetrate from one side and the sewage introduced from the sludge outflow pipe 621 to the filter 420 placed in the housing 410, and the side surface thereof. The side door 412 is configured to allow the filter 420 to be placed and separated from the housing 410, and the upper door 413 is configured on the upper surface thereof to open the upper door 413 for food waste. To be discarded. In addition, a protrusion 411 is formed on the bottom surface of the housing 410, which is a one-way valve 422 while pushing the one-way valve 422 of the filter 420 when the filter 420 is to be described below. This is to open and communicate with the overflow pipe (423). In addition, the discharge pipe 414 is connected to the drain pipe 150 on the lower surface of the housing 410, so that sludge and the like are filtered down by the filter barrel 420 and fall into the discharge pipe 414. By joining the flow of sewage to the drain pipe 150 is to be finally discharged to the storage tank (500). The housing 410 is preferably installed in an exposed state on the ground in order to allow the user to replace or clean the filter 420 or to directly throw food waste. Therefore, it is reasonable to install the housing 410 to be used in parallel with the food waste collection box in a house.

The filter 420 has a shape in which an upper surface thereof is opened, and a plurality of water outlet holes 421 are formed at the side thereof to allow the sewage introduced into the filter to be discharged to the outside of the filter 420 in a state in which sludge is filtered. In addition, the lower surface of the filter barrel 420 is formed with a one-way valve 422 facing the projection 411, the one-way valve 422 is opened and closed only in the inner direction of the filter cylinder 420 by the projection. It is configured to be. That is, when the filter barrel 420 is placed in the housing 410, the one-way valve 422 is opened by the protrusion, and the one-way valve 422 is separated when the filter barrel 420 is separated from the housing 410. ) Is closed. In addition, the filter barrel 420 is characterized in that the overflow pipe 423 is formed with a plurality of water inlet hole 424 on the side at the position where the one-way valve 422 is formed. As the overflow pipe 423 is formed, the sewage flowing into the filtration tank 420 is introduced into the overflow pipe 423 through the water inlet hole 424 while the sludge is filtered, and the sludge thus filtered is filtered. Sewage is discharged to the bottom surface of the housing 410 by opening the one-way valve 422 and the sludge filtered sewage is discharged through the discharge pipe 414.

The overflow pipe 423 should be lower than the height of the side of the filter 420 in order to prevent the sewage flowing into the side of the filter 420.

In addition, it is reasonable that the clogging portion 425 is configured at the lower side of the side of the filter barrel 420, which is to prevent the sewage from the filter barrel 420 when the filter barrel 420 is separated from the housing 410. to be.

On the other hand, the sump 100 according to another embodiment of the present invention may be composed of prefabricated blocks 170, 180, 190 divided into at least two along the longitudinal direction.

For example, as shown in FIG. 2, the water collecting well 100 is composed of prefabricated blocks divided into a first block 170, a second block 180, and a third block 190.

According to FIG. 2, the first block 170 is disposed at the top thereof to form a recess 171 recessed inward along a circumference of the upper surface such that the collection cover lid a is coupled thereto.

The second block 180 is coupled between the first block 170 and the third block 190 disposed at the bottom thereof, and the upper and lower portions thereof are open. In addition, the second block 180 may have a different block height according to the depth of the sump 100. That is, when the depth of the sump is deep, a long block may be applied, and the second block 180 may not be applied when the depth of the sump is shallow.

On the other hand, the third block 190 is disposed at the lowermost portion is coupled to the lower portion of the first block 170 or the second block 180, the lower surface is closed.

As described above, by constructing the catchment block 100 as a prefabricated block, the construction time can be shortened and the construction cost can be reduced, and the depth control of the catchment 100 can be easily adjusted through the second block 180. There is a characteristic.

Here, the first, second and third blocks are formed on the upper surface or the lower surface in contact with each other coupling jaw (a) or a coupling groove (b) having a shape corresponding thereto.

For example, as illustrated in FIG. 2, a coupling jaw b is formed at a lower surface of the first block 170, and a coupling jaw b is formed at an upper surface of the second block 180 coupled thereto. The same coupling groove (c) is formed in the shape corresponding to. Also preferably, although not shown in the drawings, it is reasonable to apply waterproof silicone to these bonding surfaces to improve airtightness.

Lastly, according to FIG. 2, the shape of the water collecting well 100 is shown as a shooting type, but the present invention is not limited thereto and may be configured in various shapes such as a circle and an ellipse.

In the present invention, the sewage treatment system of the present invention forms three kinds of sewage flows, and the first sewage flow W1 corresponds to a case where the amount of sewage introduced into the inlet pipe 140 is small as shown in FIG. 1. The downstream flow from the first chamber (105) to the second chamber (120) and flows through the partition wall 110 of the second chamber (120) and the third chamber (130), and the sewage that flows is filtered. The sludge is introduced into the storage tank 500 by the filter medium 660 of the column 600 in a filtered state, and is configured to discharge the sewage filtered first.

The flow of the second sewage (W2) is a case where the level of the sewage is increased and the backflow of the sewage to the inflow pipe 140 becomes a problem, and the first buoyancy type S / W 210 receives an ON signal due to the sewage level. The first suction pump 310 is operated under the control of the control unit 700 by the output signal, and the sewage is forced out into the sludge accommodating part 400 to filter sludge from the sludge accommodating part 400. To discharge to the reservoir (500). By the flow of sewage (W2) it is possible to prevent the backflow of sewage, the problem of decay, such as by the sludge deposited in the chamber is solved, even in the case of sewage discharged for forced sludge in the sludge receiving unit 400 By filtering off, it is also possible to discharge the filtered sewage into the storage tank.

The third sewage flow (W3) is a case where the sewage level is higher than the second, so that the sewage cannot be treated by the forced suction amount of the first suction pump 310, and the second buoyancy S / W by the sewage level 220 also outputs an ON signal, and the second suction pump 320 also operates under the control of the control unit 700 according to the output signal so as to force the sewage through the second discharge pipe 321 to the drain pipe 150. By bypassing, the treatment efficiency of the sewage flowing into the sump 100 is increased based on the flow W3 of the sewage. In addition, the flow of sewage (W3) is intended to be able to treat the sewage auxiliary if the first suction pump 310 is broken.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
