In a kind of more concrete embodiment, between each unit person in charge and soil pipe, one first valve is set, between each unit person in charge and rainwater pipe, one second valve is set.In the rainy day, for the landfill unit that is filled with rubbish, open first valve, close second valve, make sewage be delivered to the sewerage treatment place through soil pipe; For the landfill unit of not filling out rubbish, close first valve, open second valve, make rainwater pass through rainwater and discharge.

Preferably, the arragement direction that the unit is responsible for is approximately perpendicular to the bearing of trend in mountain valley, and extends upward along the hillside.The unit arm then is responsible for radial extending out from this unit, with the rainwater of interception respective regions.Can be responsible for for each unit a mozzle is set, this mozzle along the mountain valley lowest part bury underground, be delivered to outside the landfill yard so that the rainwater of collecting is responsible in the unit, so that be delivered to rainwater pipe and soil pipe through aforementioned first valve and second valve.

In a kind of specific embodiment; Carry out dumping from downstream one end in mountain valley; Like this, on rainy day, the rainwater of landfill unit is derived through the mozzle that is connected to this unit delivery port; The not landfill unit at the upper reaches is then collected rainwater through separately the person in charge and arm, and discharges through corresponding mozzle.

Further; Carry out dumping from the upper reaches one end in mountain valley; Like this, on rainy day, the rainwater of landfill unit imports sewage reservoir through the mozzle that is connected to this unit delivery port; And the not landfill unit in downstream also need not be laid the person in charge and arm, and rainwater is directly derived through the mozzle that is connected to this unit delivery port.

Through method of the present invention, can the sewage generation in the large tracts of land refuse landfill be dropped to minimum level, thereby alleviate the pressure of sewerage treatment greatly, have very big environmental benefit and economic benefit.
