Abstract
TECHNICAL FIELD The present invention relates to a device for reducing upflow and downflow non-point pollution. The up-down flow type non-point pollution abatement apparatus of the present invention can selectively use the up flow filtration system and the down flow filtration system under the control of the control unit, so that a proper filtration system can be applied according to the state of the inflowed polluted water.
The present invention can provide an excellent backwashing effect because the backwashing portion is located inside the filter material portion and includes the isolation portion. Further, according to the present invention, the position of the filter material can be adjusted according to the filtration method, and a space for cleaning the inside of the filtration tank can be secured even if the filtration tank is made small.
Description
The present invention relates to a non-point pollution abatement apparatus, and more particularly, to a non-point pollution abatement apparatus capable of selectively using an upflow filtration system and a downflow filtration system under the control of a control unit.
Generally, the sources of water pollutants can be classified into point pollutants and nonpoint pollutants. Point pollutants are constantly generated at relatively constant points such as domestic sewage and factory wastewater, and thus there is no significant variation in the amount of emissions during rainfall or non-rainfall, while non-point pollutants are released along with surface runoff during rainfall Pollutants such as dust and garbage on the surface of the earth or in the air, fertilizers and pesticides sprayed on agricultural land, and housing runoffs. Point pollution sources come from wastewater discharge facilities such as factories and workplaces, so it is easy to collect because of the clear route of outflow, and the seasonal impact is relatively small. However, nonpoint pollution sources are difficult to collect and difficult to design and maintain because of the amount of generated and discharged amount greatly depends on weather conditions such as precipitation.
The non-point pollution abatement system has many treatment methods, but it can be installed in a narrow site and has a high efficiency. Therefore, a method of filtering contaminated water using a filter medium is widely used. The filtration method is a downflow type in which contaminated water is passed through from the upper portion of the filter medium to the lower portion and an upward flow type in which the contaminated water is filtered through the upper portion of the filter medium. Conventionally, due to a spatial problem and a cost problem, a single non-point pollution abatement device performs filtration only in one of an upflow type and a downflow type. However, there is a problem in that when the filtration is performed by one method, when the surface to be filtered is blocked by the pollutant, the filtration function itself is stopped and the time for replacing the filter medium is shortened.
In Korean Patent Publication No. 2012-0045189, a plurality of filtration tanks are provided and filtration is performed by an upstream type and a downstream type. However, this method does not use the filtration method selectively in one filtration tank, so there is a problem that a plurality of filtration vessels require a lot of installation space, and that the filtration time is long, The filtration function is stopped even if the downstream filtration media is usable. In addition, the downward flow needs to be installed on the upper side, and the upward flow needs to be installed on the lower side for facility inspection and cleaning. There is a problem in that it is difficult to move from the inside to the inside to deepen the facility or to enter the inspection for securing.
SUMMARY OF THE INVENTION An object of the present invention is to provide an up-down flow type non-point pollution reduction device capable of selectively using an upflow filtration method and a downflow filtration method.
Another object of the present invention is to provide an apparatus for reducing non-point pollution in an upper and a lower flow-through type which can clean the filter media cleanly during backwashing.
Another object of the present invention is to provide a non-point pollution reduction apparatus capable of stably supporting a filter unit while moving a filter unit for filtration or filtration.
The apparatus for downpouring non-point pollution includes a settling tank, a filtration tank, a collecting tank, and a control unit. The filtration tank has a first bank, a second bank, a filter, a drain pump, and a backwash. The first partition wall forms a boundary with the sedimentation tank, and has a first inlet port on the upper side and a second inlet port on the lower side. And the first discharge port is located on the upper side of the second bank. The filter unit is installed between the first partition and the second partition such that the first inlet and the first outlet are located at the upper portion and the second inlet is located at the lower portion. The filter media is filled with filter media. The drain pump pumps water under the first outlet. The backwash section backwashes the filter media of the filter media. The water collected in the filtration tank is collected in the collecting tank. The control unit regulates the first inlet, the second inlet, the first outlet, and the drain pump.
The filter unit of the upper / lower flow type non-point pollution abatement device according to the embodiment of the present invention may include an upper fixed plate located on the upper portion of the filter medium and a lower fixed plate located on the lower portion of the filter medium. The backwashing section is installed in the upper fixing plate and the lower fixing plate, respectively. The backwashing section includes an air cleaning pipe, a water washing pipe, and an isolation portion. The isolator isolates the air wash tubing and the water wash tubing from the filter media.
The filter unit of the upper and lower flow type non-point pollution abatement device according to the embodiment of the present invention can be supported by the support pillars.
In the upper and lower flow-through type non-point pollution abatement apparatuses according to the embodiments of the present invention, the filter unit may include a screen in at least one of an upper portion and a lower portion.
The filter unit of the apparatus for downpouring non-point pollution reduction according to an embodiment of the present invention can be installed so as to be movable up and down. The control unit can control the position of the filter unit.
In the apparatus for reducing non-point pollution in the upper stream and the downflow stream according to the embodiment of the present invention, the settling tank, the filtration tank, the water collecting tank, and the control unit can be arranged in a rectangular shape.
The non-point pollution reduction apparatus according to the present invention can selectively use the upflow filtration system and the downflow filtration system under the control of the control unit. Therefore, a suitable filtration method can be applied according to the state of the inflowing contaminated water. In this case, by changing the filtration system, the filter material can be back-washed, and the service life of the filter material can be increased accordingly.
In the non-point pollution abatement device according to the present invention, the backwashing effect is increased since the air cleaning gutter water washing pipe is not in direct contact with the filter material by the isolator during backwashing.
According to the non-point pollution reduction apparatus of the present invention, the position of the filter unit can be adjusted according to the filtration system by moving the filter unit, and a space for cleaning the inside of the filtration unit can be secured even if the filter unit is small.
In addition, the non-point pollution abatement device according to the present invention can correct vibration of the filter material due to movement of the filter material by applying vibration to the filter material part, and clean the pollutants in the filter material part easily.
