Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filtration system capable of backwashing and a drainage control system using the same.

The present invention relates to a filtration facility, and more particularly, to a filtration facility that removes non-point pollutants by introducing rainwater during rainfall, and backs up purified rainwater to clean the filtration facility, The present invention relates to a filtration system capable of backwashing, which is capable of automatically controlling the drainage of rainwater purified in the filtration facility to prevent urban flooding and runoff of streams, and a drainage control system using the same.

The pollutants are divided into point pollutants and nonpoint pollutants. Point pollutants are pollutants discharged at certain points such as factories and sewage treatment plants. Therefore, even if the pollutant concentration is very high, the pollutant discharge route is clear and easy to collect. As the influence is relatively small, it is possible to estimate the amount of annual production, and it is easy to design, maintain and manage treatment facilities such as treatment plants.

On the other hand, non-point pollution sources generate unspecified pollutants such as pesticides, fertilizers, pollutants, oil, heavy metals, and tire powder in unspecified places such as cities, roads, farmland, The non-point pollutants that are largely influenced by rainwater in a rainy season are difficult to identify the sewage disposal equipment and are difficult to maintain. When large amounts of pollutants enter the river or groundwater resources, they pollute the water quality, And destroys the habitat of aquatic ecosystems.

In order to solve these problems, rainwater containing non-point pollutants is discharged after treating non-point pollutants through various stages of sedimentation or filtration in a suspended state before entering streams or groundwater resources.

As a conventional technique for removing non-point pollutants generated at an unspecified site, Korean Patent Registration No. 10-1099768 discloses a nonpoint pollutant reduction apparatus in which various kinds of non-point pollutants A grating formed to flow in; A housing installed in the lower part of the grating and having an upper inflow chamber and a lower lower treatment chamber formed in a stepped shape; A drain hole is formed in the lower part of the one side of the processing chamber to collect the large amount of non-point pollutants while discharging the introduced outflow, and a swash plate is formed on the upper side of the drain hole Inlet tank; A treatment tank having a drain disposed on the bottom to filter out non-point pollutants having a small size and a small size flowing out from the inflow tank while the filter medium is installed inside the treatment chamber; A drain pipe connected to the treatment chamber bottom of the housing to discharge the rainwater flowing down from the treatment tank; And a non-path-pipe reducing device connected to the drain pipe from an upper part of the processing chamber of the housing to discharge the overflowing effluent into the processing chamber.

However, the non-point pollution source reduction apparatus described above can be installed simply and inexpensively, but the treatment tank is divided into upper and lower portions to store the filter material in the lower portion to reduce nonpoint pollutants in stages. However, a large number of holes So that the non-point pollutants and the filter media flow into the drain pipe together with the non-point pollutants, which are not removed properly but are washed away.

As another conventional technique, Korean Patent Laid-Open Publication No. 10-2008-0004142 (Jan. 09, 2008) discloses an apparatus for rapid rapid filtration for an initial stormwater treatment facility and a water supply system, wherein a rectangular If you want to clean the inside of the filter, remove the plug, open the filter cap, connect the bellows hose to the backwash pipe, and put the hose. Then, after the sedimentation valve is locked, the stormwater (raw water) enters the filter. Fit the filter line valve and lock the overdrain line valve. When the inside of the filter is filled with water, it is known to open the wastewater sludge pipe valve to automatically clean the inside of the filter, clean the filter to clean water, and supply the clean water.

However, in the above-described early stormwater treatment facilities and the rapid filtration apparatus for water supply, a complicated process such as opening a back-flush valve to remove a filtration device, removing a stopper, connecting a bellows hose to a backwash pipe, opening a filter lid, The efficiency of the work is deteriorated. In addition, since the inside of the filter must be filled with water to clean the filtration device, there is a disadvantage that the raw water is wasted, and the washed water is discharged to the outside along the wastewater sludge pipe, thereby causing environmental pollution .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of a filtration system capable of backwashing and a drainage control system using the same according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the filtration system according to the present invention includes a storage tank 10, a purification tank 20, and a drain tank 30.

As shown in FIG. 2, the storage tank 10 includes an inflow pipe 11, an inflow storage space 13, and an outflow pipe 15 (see FIG. 2) so as to allow rainwater to flow in the rainwater, And an outflow pump 17.

The inflow pipe (11) is formed on one side of the storage tank (10) to introduce rainwater into the inflow storage space (13) when rainfall occurs. It is preferable that the diameter of the inflow pipe 11 is variable according to the amount of annual precipitation and the intensity of rainfall per hour of the inflow pipe 11.

For example, when installed in an area having high annual rainfall and hourly rainfall intensity, it is desirable to increase the diameter of the inflow pipe 11 so as to increase the amount of rainwater flowing in, and the annual rainfall amount per hour and rainfall per hour It is also possible to form the area having a low strength to have a relatively small diameter so as to reduce the construction cost.

The inflow storage space 13 stores the rainwater initially introduced from the inflow pipe 11 for a predetermined period of time. The inflow storage space 13 stores initial rainwater containing the most non-point pollutants and foreign substances, thereby allowing non-point pollutants and foreign substances to settle.

The outflow pipe (15) is formed on the other side of the storage tank (10) and discharges rainwater when the water level becomes higher than the designated water level in the inflow storing space (13). That is, the outflow pipe 15 is formed at the upper end of the inflow storing space 13, and the rainwater flows out when the level of the rainwater in the inflow storing space 13 becomes equal to or higher than the height of the outflow pipe 15.

It is preferable that the outflow pipe 15 has a height corresponding to the inflow pipe 15 so that the inflow pipe 15 does not allow the inflow of washing water or foreign matter.

The outflow pump 17 is provided to discharge the rainwater stored in the inflow storing space 13. The outflow pump 17 is operated to let the rainwater stored in the inflow storing space 13 for a predetermined period flow out to the septic tank 20 along the pump tube 18.

The outflow pump 17 includes a buoyancy material 17a to vary the position of the outflow pump 17 according to the level of the inflow storage space 13. The buoyancy material (17a) allows the effluent pump (17) to float in the rainwater that has been stored so that the rainwater having a high water level can be leaked first. That is, the outflow pump 17 firstly discharges the rainwater at a high level, which is relatively clean rainwater, from the stored rainwater.

The outflow pump 17 is provided with a sediment sensing member 17b so that sediment precipitated at the lower end of the inflow storage space 13 can be prevented from flowing out. The sediment sensing member 17b senses sediment precipitated in the inflow storing space 13 and detects the sediment to prevent damage to the outflow pump 17. [

Therefore, the storage tank 10 allows the rainwater to flow into the inflow pipe 11 at the time of rainfall, to store the inflowing rainwater into the inflow storing space 13, and to flow into the inflow pipe 15 when the level of the rainwater increases to the height of the outflow pipe 15 The rainwater flows out to the outflow pipe (15). The storage tank 10 operates the discharge pump 17 after a certain period of time after the end of the rainfall so that the rainwater stored in the inflow storage space 13 flows out along the pump tube 18. At this time, the effluent pump 17 first discharges the rainwater having a high water level due to the buoyancy material 17a floated on the water surface and the sediment sensing member 17b sensing the sediment at the bottom, and the water level of the rainwater gradually decreases, 17b), the rainwater spill is stopped. It is preferable to dred sediment precipitated in the inflow storing space 13 after a lapse of a certain period of time.

[

The water tube 29 has a slope for facilitating the movement of wash water and foreign matter, and is formed at a higher position than the one end connected to the storage tank 10 and connected to the septic tank 20.

The water head pipe 29 is connected to the water head pipe 29 so as to prevent the sediment material precipitated in the inflow holding space 13 from blocking one end of the water head pipe 29 and preventing the washing water from flowing into the inflow storing space 13.

It is preferable that the drainage pump 37 controls the operation according to the presence or absence of precipitation in the installed area and the level of the river.

The backwash pump 39 transfers a part of the rainwater stored in the drainage storage space 33 to the purification tank 20. The backwash pump 39 is provided with a backwash pipe 39a for transporting rainwater during operation and further includes a backwash nozzle 39b for spraying the transferred rainwater from the seawater 20.

The backwash pipe (39a) is connected to the lower end of the purification space (23) at the lower end of the drainage storage space (33). The backwash nozzle (39b) is provided to emit rainwater from the lower end of the purification space (23) to the upper end thereof. It is preferable that the backwash pump 39 is operated by increasing the water pressure so that the purifier 20 can be cleaned by the rainwater sprayed from the backwashing nozzle 39b.

When the backwash pump 39 is operated, the cleaned water 20 is cleaned and contaminated rainwater and foreign matter move along the waterpipe 29 to the storage tank 10 or purify the rainwater again in the purified water tank 20, 30).

Therefore, the drain tank 30 receives the rainwater conveyed from the conveyance pipe 25 and temporarily stores the rainwater in the drainage storage space 33, and then, depending on the presence or absence of precipitation in the area where the drainage tank 30 is installed, The drain pump 37 is operated to drain the purified rainwater through the drain pipe 35.

The drainage tank 30 operates the backwash pump 39 when a predetermined period of time has elapsed so that the purification efficiency of the purification tank 20 can be optimized to return a part of the rainwater stored in the drainage storage space 33 to the backwash pipe It is also possible to wash the septic tank 20 by spraying the rainwater through the backwash nozzle 39b.
