Background
At present, in projects such as upgrading and synergy, diversion and reconstruction of sponge cities and urban rainwater and sewage, a residential district is commonly in a balcony stand pipe rainwater and sewage mixed flow discharge site, a stand pipe which is used for discharging roof rainwater is connected with sewage of a washing machine and sewage of a mop pool, so that sewage enters a river, other pollutants are added to be dissolved in water, and pollution is caused to river water environment. If the sewer pipe of the balcony is directly communicated with the sewage pipe, a large amount of rainwater which does not need to be treated enters the sewage pipe, and the burden of urban sewage treatment enterprises is increased.
For this reason, as disclosed in CN 203320674U, the balcony rainwater and sewage separation device adopts sedimentation tank, baffle, lever and floater, balcony downspout is connected to one side of sedimentation tank, sewage pipe and rainwater pipe are connected to the opposite side, one end and the floater of lever link to each other, the other end links to each other with the baffle, there is a fixed point in the middle of the lever, wash clothes etc. water yield at ordinary times for hours, the floater sinks at the bottom of the tank, the baffle blocks the rainwater pipe, water can get into sewage treatment enterprise through the sewer pipe, when the water yield such as raining is great, the floater floats, through the effect of lever, the baffle blocks the sewer pipe, the rainwater passes through the rainwater pipe and discharges, avoid aggravating sewage treatment enterprise's burden. The structure adopts a multipoint hinge structure, when sundries exist in water inlet, stagnation of the baffle plate during overturning is easy to cause; particularly, when the rainwater is discharged, the drain is not tightly closed, the water stopping effect is poor, and a large amount of rainwater still enters the sewage pipeline. In addition, most residential communities are provided with multiple floors, the threshold value of the flow triggered by the rain and sewage separation device with the structure is fixed, and the lower sewage interception effect is poor for different inflow rates of all floors of the same unit, so that a phenomenon that a large amount of rainwater enters a sewage pipeline still exists actually.
