Accompanying drawing explanation
Fig. 1---the dirty flow dividing structure schematic flow sheet of rain of the present invention.
In figure, each label represents that corresponding component names is as follows:
Septic tank 1, sewage pump 2, manhole 3, soil pipe 4, rain pipe 5, increase-volume rain pipe 6, grit chamber 7, rainfall regulative pool 8, greening use water lift pump 9, check device 10.
Detailed description of the invention
Detailed description of the invention below in conjunction with example is further explained the present invention.
As shown in Figure 1:
Using former for grown-ups and children district interflow tubulation as rain pipe 5, cutting off with septic tank 1 tube connector place, close, namely rain pipe 5 not to be communicated with septic tank 1 (being originally connection), rain pipe 5 is connected with increase-volume rain pipe 6 at manhole 3 place, and increase-volume rain pipe 6 other end directly be arranged on land use for greening below ground rainfall regulative pool 8 be connected, rainfall regulative pool 8 is used to the rainwater can not discharged in time when accepting heavy rain, increase-volume rain pipe 6 has certain gradient of facing upward towards rainfall regulative pool 8, rainfall regulative pool 8 front portion arranges grit chamber 7 simultaneously, in order to the silt carried secretly in temporary rainwater, rain pipe 5 other end is communicated with Urban Rainwater Pipe Networks (omit in figure, do not draw).In rain pipe 5, arrange soil pipe 4, form tube-in-tube structure, soil pipe 4 one end is communicated with septic tank 1, and the other end is communicated with municipal sewage pipe network (omit in figure, do not draw).Soil pipe 4 branch line pipeline section connects check device 10, prevents sewage backflow, and its form can according to concrete pipe pressure in different ways, as gravity flap valve, upwards-raised inverted U structure etc.It is emphasized that sewage is delivered to soil pipe 4 after carrying out supercharging by sewage pump 2 in septic tank 1, form lowpressure stream induction system, in rainfall regulative pool 8, rainwater is used as greening water after the supercharging of greening use water lift pump 9.
