Hereinafter, the storage type non-point pollution reducing method will be described in detail with reference to FIG. 7. 7 is a flow chart for explaining a storage type non-point pollution reduction method according to the present invention.

First, in step S100, the meteorological information is transmitted in real time to a management control unit including a data construction server that collects and builds water quality data, quantity data, rainfall data, and watershed status data during the dry and rainy seasons. Here, the management control unit builds a simulation system that can calculate the pollution load and initial outflow by rainfall intensity during dry and rainy seasons through the data constructed by collecting water quality data, quantity data, rainfall data and watershed status data. .

In addition, the data construction server classifies the rice fields, fields, forests, land, roads, residential areas, land, etc. according to the land use characteristics in the watershed through the current status survey on the target watershed, and the watershed numerical elevation data (DEM) and satellite The watershed status data, which identifies the watershed slope and runoff in the watershed, is constructed using the photographs. Here, the outflow path is divided into drainage, sewage and storm drains, including the type of conduit, pipe diameter, etc., and the slope and friction coefficient for each outflow path are obtained as basic basin data.

Next, before the rainfall occurs, the simulated rainfall, the predicted rainfall duration and the predicted rainfall intensity are compared with the previously constructed data, and the non-point pollution initial discharge is calculated according to the simulated calculated results (S200).

Thereafter, the treated water stored in the non-point pollution treatment apparatus for treating the influent including the non-point source is discharged before the occurrence of the rainfall by the initial discharge amount calculated based on the calculated initial discharge amount (S300). Accordingly, in the non-point pollution treatment apparatus, it is possible to sufficiently secure the treatment capacity necessary for the storage before the occurrence of rainfall, and when rainfall occurs, the non-point pollutant caused by the initial discharge is treated by sedimentation function, vegetation purification, and soil microorganisms.

Next, when the actual rainfall occurs, the initial discharge amount according to the measured rainfall, rainfall duration and rainfall intensity using the rainfall meter is redefined (S400). Then, it is determined whether additional discharge of the treated water stored in the non-point pollution reducing device is compared by comparing the initial discharge amount calculated using the weather information before the occurrence of rainfall with the recalculated initial discharge amount (S500).

In the step S500, if the initial outflow amount of the actual rainfall is larger than the initial outflow amount calculated using the weather information before the occurrence of the rainfall, the flow rate of the treated water stored in the nonpoint pollution treatment device is increased, so that it is additionally necessary in the nonpoint pollution treatment device. Processing capacity is secured (S600).

Hereinafter, the results of the runoff characteristic analysis for rainfall thought by size for constructing data of the management control unit by the inventor of the present invention will be described with reference to FIGS. 8 to 11.

8, 9, and 10 are graphs showing the results of the hydrological simulation in the case of rainfall events 179.0 mm, 35.8 mm, and 17.5 mm, respectively, and FIGS. 10, 11, and 12 are cases of rainfall 179.0 mm and 35.8 mm, respectively. It is a graph showing the M (V) curve (M (V) curve).

In the present invention, the runoff characteristics analysis was performed for the construction of data by size, and the rainfall events of 100mm, 50mm, and 30mm or less were defined as large, medium, and small rainfall, respectively. It can also be used as construction data through sampling and analysis.

In addition, runoff analysis according to land use characteristics was performed to construct the model. Factors affecting the hydrograph in data construction are largely classified into node parameters and link parameters. Node parameters are watershed area, impermeability, watershed width, watershed slope, penetration rate, concave surface. There is a storage amount, and the link parameter is defined by the type of pipe, the diameter of the pipe, the length of the pipe, the roughness coefficient, the slope of the pipe, and the like. Parameters such as watershed area and impermeability were calculated from physical characteristics and measured data obtained through geographic information system and remote sensing data, and parameters such as roughness coefficient and penetration rate were measured in real watershed. The value was difficult to measure and was calculated through the calibration of parameters due to uncertainty in the model and the optimization of trial and error method at the initial setting.

식 (4)M (V) curve (M (V) curve) well known in the art was used to quantitatively estimate the initial outflow of nonpoint source for the construction of the data of the present invention. If the cumulative load of dimensionless pollutants is greater than the dimensionless cumulative runoff, it is determined that the initial runoff occurs. The larger the slope of the straight line, the clearer and clearer the initial runoff level can be. If this difference is equal to or greater than a preset value (eg 0.2), it is determined that an initial outflow has occurred. The initial outflow phenomenon can be quantified by mass-based first flush (MFF), and in the present invention, the dimensionless M (V) curve (M ()) using the following equations (1), (2), (3), etc. V) curve). Δ (LF) is the difference between the non-dimensionalized cumulative load and the cumulative flow rate, and when this value is positive, it is determined that an initial spillage occurs. A larger value indicates that the discharge rate of the pollutant load is larger than the flow rate. .
L = m (t) / M (1)
F = v (t) / V expression (2)
△ = LF equation (3)
Where L: dimensionless pollutant load, m (t): pollutant load (g) transferred to time t, M: total runoff load (g), F: dimensionless cumulative runoff, v (t): Flow rate (m 3) flowed out to time t, V: total flow rate (m 3).
If it is determined that the initial runoff occurs using the M (V) curve, the load of pollutant is calculated by the flow average weight (EMC). The flow weighted average concentration (EMC) is calculated as shown in Eq. (4) by dividing the total load of accumulated pollutant spilled over the total rainfall duration time T hours by the total accumulated runoff. In Eq. (4), C (t) and Q _TRu (t) represent the pollutant runoff concentration and runoff flow rate for rainfall duration t.

Equation (4)

In the present invention, the basic data for data construction is stored in a database (DB) server, and calculates the initial discharge amount before the rainfall based on the basic data and real-time weather information stored in the DB server.

In reality, when rainfall occurs in the target basin, the outflow of nonpoint sources by rainfall starts along the outflow path of the basin, and nonpoint sources are introduced into the river at the end of the basin. In the present invention, in order to treat the non-point source contained in the initial outflow water, especially inflowed non-point source, in the present invention, after the initial runoff is desalted by installing a movable beam in the stream, the non-point source is included as a pretreatment device and a nonpoint pollution reduction device through an induction channel. Initial runoff can be introduced. An inflow flowmeter is attached to the front end of the induction channel so that a flow rate exceeding a predetermined initial outflow amount by the management control unit can be closed to prevent inflow by closing the water gate of the induction channel.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Will be clear to those who have knowledge of.
