Description

TECHNICAL FIELD [0001] The present invention relates to an initial excellent treatment apparatus having a backwash function,
The present invention relates to an initial stormwater treatment apparatus and a treatment method having a backwash function.
Water pollution sources are divided into point pollution sources and non-point pollution sources. Point pollution sources are mainly used for monitoring the occurrence area and generation amount such as domestic sewage generated in general households or business areas, industrial wastewater discharged from factories, animal wastewater generated in large- This is a relatively easy subject and is the main object of sewage disposal.
On the other hand, non - point pollution source refers to drainage from agricultural drainage, mine waste water, livestock wastewater from small scale livestock facilities, living sewage or forest in rural areas without sewerage, and these pollutants are relatively dependent on natural treatment due to less contribution of pollution.
Nonpoint pollution sources are also called non-specific pollution sources, surface pollution sources, mobile pollution sources, or other pollutants. Unlike point pollution sources that have specific discharge paths, nonpoint pollution sources are unspecified discharge routes such as urban road drainage and agricultural drainage. Quot; refers to a place or an area where non-point pollutants are generated through the air.
Aquaculture facilities, transportation facilities, maintenance or disposal facilities, simplified processing facilities for enriched fisheries products, photo processing facilities, etc., which have been changed from 'specific facility' to 'other water pollution source' , Product yard, land change area, and other facilities.
Non-point pollutants are mainly pollutants that run out along with surface rainfall runoff when they are exposed to rain. These include fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, Residues, and air pollutants that have fallen on the surface of the earth.
Therefore, rainwater (rainwater runoff) containing all pollutants is actually the main nonpoint source. Since non-point pollutants usually flow out with a lot of rainfall, there is a large difference between daily and seasonal emissions, and it is difficult to forecast and quantify, and it is affected by weather conditions, geology, and topography which are difficult to manure.
The point pollution sources such as domestic sewage are steadily decreasing due to the establishment of basic environmental facilities, but the nonpoint pollution sources are continuously increasing due to the improvement of land use. In particular, the impact of non-viscous salts on water quality is predicted to reach 65 ~ 70% by water sector in 2015, and active management of non-point pollution sources is required.
In 2007, the government revised and amended the 'Law on Water Quality and Aquatic Ecosystem Correction' to select and expand objects to be installed in nonpoint pollution abatement facilities.
As of the end of 1999, as a result of the "Non-point Source Pollution Research Service" (conducted in June 2000) on the upper stream of the Paldang Dam in the Han River, the main water source of the metropolitan area residents, The pollutant loads generated from point sources such as industrial wastewater and livestock wastewater were 804.4%, 130,650t / year, and the pollution load from nonpoint pollution sources was 19,3193t / year, which was 19.6%.
In addition, the non-point source pollution source was estimated to be 44.5% of the total discharge load (BOD standard), and nonpoint source pollution was found to have a significant influence on water pollution. The Geum River, Nakdong River and Youngsan River . Therefore, as the regulations for point sources with regulatory standards are continuously strengthened and environmental facilities are expanded, the impact of non - point pollution sources on water quality will gradually increase.
As a countermeasure for reducing pollution, conventionally, in order to reduce pollution, the road surface drainage in an urban area is provided with a storage tank to allow the pollutants generated due to the initial rainfall to be settled and discharged, · Agricultural drainage, which contains a large amount of agricultural chemicals, was installed in a reservoir, a wetland purification facility, and aquatic plants to prevent direct influx into the river.
However, such a countermeasure would be to treat only the initial rainfall, which is the actual nonpoint source pollutant discharged with all the pollutants, by continuously treating the rainwater after a certain period of time when the concentration of the pollutant decreases, There is a problem that the maintenance cost rises.
In addition, in the case of the conventional early stormwater treatment apparatus, in order to clean the filter, the operator is required to replace the filter manually or to use the washing water to clean the filter, which is not economical. There has been a problem in that the time that can not be attained is prolonged.
Therefore, it is possible to use only the initial effluent containing almost all of the non-point pollutants, and it is possible to perform the process from the single treatment unit to the backwash of the filter, And methods.

The treated water filtered by the filter 31 from the lower end to the upper end of the filtration tank 30 flows into the drain tank 40 through the outflow hole 37 (S5). When the treated water flows into the drain tank 40 and the water level of the drain tank 40 exceeds the outlet pipe 43 provided in the drain tank 40, the treated water flows through the outlet pipe 43 into the reservoir 60 (S6), and the treated water stored in the storage tank 60 is recycled to the landscape water or the like (S7). Also, in this process, the controller 50 can adjust the position and height of the filter 31 by driving the filter moving means 31.
Hereinafter, a method of operating the initial stormwater treatment apparatus 100 having a backwash function according to an embodiment of the present invention in a backwash mode will be described. Fig. 10 shows a flowchart of a method of operating the initial stormwater treatment apparatus 100 having a backwash function in a backwash mode according to an embodiment of the present invention. 11 is a cross-sectional view of an early stage miscellaneous processing apparatus 100 having a backwash function operated in a backwash mode according to an embodiment of the present invention.
The controller 50 drives the backwash pump 41 in order to operate the initial goodwood device 100 according to the present invention in the backwash mode. By the operation of the backwash pump 41, the treated water stored in the drain tank 40 is pumped to the washing unit 33 (S10). Therefore, the treatment water stored in the drain tank 40 is sprayed from the cleaning nozzles 34 provided in the cleaning unit 33 to the filter 31 provided at the lower side (S20), and the filter 31 is washed (S30).
According to an embodiment of the present invention, the spraying angle of the washing nozzle 34 can be adjusted, including the washing adjusting part 35, and the washing part 33 can be moved up and down, The distance between the first and second portions 33 and 33 can be adjusted.

The washing water is sprayed by the washing nozzle 34 so that the filter 31 is washed and the washing water having passed through the filter 31 flows into the lower end side of the filtration tank 30. The washing water flowing into the lower end of the filtration tank 30 flows into the treatment tank 20 through the contaminant removal opening 21 (S40).
Then, the control unit 50 drives the control water pump 22, and the wash water stored in the treatment tank 20 is discharged to the outside by the control water pump 22 (S50).
Therefore, the initial stormwater treatment apparatus 100 having a backwash function according to an embodiment of the present invention can be installed in the drainage tank 40, which has been stored in the drainage tank 40 filtered in the filtration mode without using any separate cleaning device, The filter 31 can be cleaned by the cleaning nozzle 34 while the treated water is recycled as it is.
12 is a block diagram showing a control flow of the control unit 50 according to an embodiment of the present invention. 12, the control unit 50 according to an embodiment of the present invention includes an inlet valve 24, a filter moving unit 31, a cleaning control unit 35, a backwash pump 41, It is understood that the pump 22 is totally controlled.
That is, the control unit 50 controls the inflow valve 24 to adjust the flow rate of the initial storm that flows into the filtration tank 30 in the treatment tank 20 in the filtration mode. In the backwash mode, The flow rate of the washing water flowing into the treatment tank 20 can be adjusted.
The controller 50 controls the filter moving means 31 to move the position of the filter 31 in the filtration tank 30 up and down to adjust the position of the filter 31. In the backwash mode, The flow rate, the injection pressure, and the injection speed of the process water jetted by the nozzle 34 can be adjusted. The controller 50 may control the cleaning controller 35 in the backwash mode to adjust the spray angle of the spray nozzle and the separation distance between the cleaner 33 and the filter 31, So that the water level in the treatment tank 20 can be adjusted by adjusting the flow rate of the wash water flowing into the treatment tank 20 to the outside.
In the initial excellent treatment apparatus 100 having the backwash function, the filtration method is a bottom-up type. In the backwash mode, the filter 31 is described as spraying the treated water from the top to the bottom. FIG. 13 shows a cross-sectional view of an early stage miscellaneous processing apparatus 100 having a top-down backwash function according to another embodiment of the present invention.
13 is similar in basic structure to the above-described processing apparatus 100, but has a contaminant removal port 21 at the upper end thereof, It can be seen that the discharge port 37 is formed at the lower end side and the washing section 33 having a plurality of washing nozzles 34 is installed at the lower end of the filtration tank 30. [
Therefore, when the initial stormwater treatment apparatus 100 having the backwash function according to another embodiment is operated in the filtration mode, the initial stormwater is introduced into the treatment tank 20 through the initial stormwater inflow pipe 10, The initial storm that has flowed into the tank 20 flows into the upper end of the filtration tank 30 through the pollutant removal port 21 provided at the upper end of the partition wall separating the filtration tank 30 and the treatment tank 20.
The initial rainwater flowing into the upper end of the filtration tank 30 is filtered while passing through the filter 31, and then flows into the lower end of the filtration tank 30. Therefore, the treated water filtered downward flows into the drainage tank 40 through the outflow hole 37 provided at the lower end of the partition wall between the filtration tank 30 and the drainage tank 40, and the treated water stored in the drainage tank 40 The water is stored in the storage tank 60 through the outflow pipe 43 and is later recycled as landscape water.
When the backwash pump 100 is operated in the backwash mode, the backwash pump 41 is driven so that the process water stored in the drain tank 40 is supplied to the washing unit 33 And the plurality of cleaning nozzles 34 provided in the cleaning part 33 are sprayed toward the filter 31 so that the filter 31 is cleaned.
