In the present invention, "dirty water" and "clean water" are understood to be domestic sewage, primary rain, or a mixture of domestic sewage and primary rain, and "clean water" is understood to be middle-late stage rain. Specifically, for the period of rainfall, the rainwater can be divided into initial rainwater and middle and late stage rainwater, the dividing mode can adopt a time-length method, a water quality method or a liquid level method in the prior art, for example, when the time-length method is adopted, the corresponding rainwater at the initial stage of rainfall is initial rainwater, the corresponding rainwater at the middle and late stage of rainfall is middle and late stage rainwater when the water quality method is adopted, the rainwater is initial rainwater when the concentration of the rainwater is higher than a certain concentration threshold value, the rainwater is middle and late stage rainwater when the concentration of the rainwater is lower than a certain concentration threshold value, and the rainwater is initial rainwater when the liquid level of the rainwater is lower than a certain liquid level threshold value when the liquid level of the rainwater is higher than a certain liquid level threshold value.
