The stirring drip washing dividing is processed；The soil that drip washing has been processed is reprinted to conveyer belt II via the anterior discharging opening of horizontal mixer (5)
(7), it is fed directly to mixing module (8)；Go to step C4；
C3, through inclination angle conveyer belt (3) by soil continuous conveying enter chemical leaching stirring module and thermal desorption module (4) in stirred
Mix and thermal desorption is processed；Meanwhile, chemical reagent and water are injected by vehicle-mounted chemical processing system (16) by spray pipeline and pumping plant
Horizontal mixer (5), makes soil sufficiently be stirred drip washing and processes；The soil that thermal desorption has been processed is in horizontal thermal desorption machine
Under discharging opening is thrown, reprint to conveyer belt I (6) via discharging opening, be fed directly to mixing module (8)；The soil that drip washing has been processed
Reprint to conveyer belt II (7) via the anterior discharging opening of horizontal mixer (5), be fed directly to mixing module (8)；
C4, environmental sanitation rubbish enter dehydrator (10) by first conveyer belt (9) and are dried, and the environmental sanitation rubbish after drying passes through the
Two conveyer belts (11) enter pulverizer (12) and are pulverized, and the environmental sanitation rubbish after pulverizing passes through the 3rd conveyer belt (13) and enters mixing
Blender (14), by stirring, biological flora is uniformly added in environmental sanitation rubbish；Add the environmental sanitation rubbish warp of biological flora
Mixing module (8) is fed directly to by conveyer belt III (15) by the anterior discharging opening of mixing and blending machine (14)；
One of D, mixing module (8) ribbon conveyer is conveyed through the soil of drip washing, thermal desorption, another ribbon conveyer
Conveying with the addition of the environmental sanitation rubbish of biological flora, and two ribbon conveyers convey in opposite directions, each dish out, so at center chute
Realize uniformly mixing, and stock ground conveyer belt (17) after center chute reaches, by the conveying in rear stock ground conveyer belt (17), will
Soil after process is delivered to rickyard (18).
7. the soil of urban sanitation according to claim 6 refuse landfill organic repair system method of work, its feature
It is：Process the chemical reagent after soil and the mixture of water has recycled via pumping plant, chemical reagent to be detected and water
When in mixture, contained pollutant levels reach prescription, recycled by reagent mixture recycle device.
