Non-point source treatment facilities require treatment by a method different from the existing sewage treatment methods, considering the characteristics of non-point source discharge. Non-point source is very irregular, contains many kinds of hardly decomposable substances, and has a very large fluctuation with time. In addition, the concentration of pollutants in early rainfall is very high. Therefore, it is necessary to effectively treat suspended substances or nutrients (nitrogen, phosphorus), which are nonpoint pollutants included in the initial rainfall of urban areas. However, most non-point source treatment facilities in Korea have a fixed treatment efficiency, making it difficult to properly treat non-point source with large change in flow rate and concentration.

Figure 10 shows a schematic diagram of the configuration around the terminal box 300 provided in the present invention. 10 (b) shows that the control unit 310 in a single terminal box 300 controls a plurality of valve drive motor 142. The terminal box 300 is basically characterized in that the control unit 310, the charging unit 320, the input unit 330 and the timer 340 is provided. The charging unit 320 charges the power generated from the power generation unit 10, and supplies power to the initial rainfall non-point source treatment system of the present invention to be driven.

It means the elapsed time until the contamination separation tube 140 is opened. In other words, when it rains and stops repeatedly, if it rains every time, it is regarded as an initial rainfall and discharged to the sewage pipe, which may overload the sewage terminal treatment plant connected to the sewage pipe or a separate nonpoint source reduction facility, and pollutants due to frequent rain. This is because it is inefficient to discharge the initial rainfall with low concentration into the sewage pipe. Therefore, the manager can set the pollution separation opening time to 2 to 3 days, preferably determined in consideration of the regional characteristics of the contaminated area.

And, the water discharge time of the bucket is a time set to discharge the rainfall collected in the bucket 220 of the rainfall measurement sensor 200. That is, the rainfall collected in the bucket 220 of the rainfall sensor 200 is observed to naturally evaporate after 2 to 3 days, but the rainfall in the bucket 220 according to the weather conditions (temperature, humidity). This is to solve the problem that the rainfall measurement sensor 200 does not accurately detect the initial rainfall when it remains for a long time. To this end, a drainage port may be provided in the bucket 220 of the rainfall sensor 200, and a driving device (motor, etc.) that may open and close the drainage hole may be added.

When the rain is not normally, the pollution separation pipe is in an open state (start), and when rainfall starts, the rainfall measurement sensor 200 measures rainfall. When the rainfall measured by the rainfall measurement sensor 200 is greater than the set pollution separation pipe closing rainfall amount, the switch 226 provided in the rainfall measurement sensor 200 is operated ('ON') to close the pollution separation pipe 140. The signal is transmitted to the control unit 310 in the terminal box (300). The control unit 310 which receives the signal for closing the pollution separation pipe 140 drives the valve driving motor 142 to close the pollution separation pipe 140 through the electric valve 141.
