step one: firstly, an instrument for detecting pipeline leakage is arranged in an instrument box (9), a detection end of the instrument is connected into a connecting pipe (4), the pipeline leakage detecting instrument, a double-shaft motor (6), a hydraulic cylinder (10) and a motor in a motor box (18) are electrically connected with an external PLC controller, then a frame (1) is pushed, the whole device is moved to a factory sewage pipeline discharge port or a pipeline outlet or other positions where leakage is easy to occur, a joint (2) is abutted with the sewage pipeline discharge port or the pipeline outlet by utilizing an external pipeline, then an adding port (24) is opened, a soil purifying and repairing reagent is added into a storage box (14), the added reagent is stored in an inner cavity (26), the adding port (24) is closed after the completion, and then the power of the whole device is turned on;

step two: when detecting that pollutants leak, an external PLC controller starts an emergency treatment mechanism (3), a double-shaft motor (6), a hydraulic cylinder (10) and a motor in a motor box (18) are synchronously started, the hydraulic cylinder (10) drives a hydraulic telescopic rod (20) to extend, two semicircular sealing plates (22) are close to each other and abut against each other, a connecting pipe (4) is closed to block leakage, the double-shaft motor (6) drives a driving shaft (7) to rotate so as to drive a movable arm (11) to rotate, so that the two buckets (13) are close to each other, the hydraulic cylinder (10) drives the hydraulic telescopic arm (12) to stretch out and draw back, the angle of the bucket (13) is regulated by the stretching of the hydraulic telescopic arm (12), the motor in the motor box (18) drives a stirring rod (19) to rotate so as to assist the bucket (13) to shovel soil, the two buckets (13) are extruded by the pressing block (23) in the process of being close to each other, thereby driving a piston (27) to move in an inner cavity (26) and press a reagent into a spray nozzle (15) from the inner part (15) when the piston (27) is ejected out of the nozzle (15), the two buckets (13) are driven by the double-shaft motor (6) and the hydraulic cylinder (10) to repeatedly open and close, the two buckets (13) pull the pull rope (17) and reset the pressing block (23), the pressing rod (25), the piston (27) and the poking piece (29) by using the pull rope (17) in the opening movement process of the two buckets (13), after the two buckets (13) are repeatedly opened and closed for a plurality of times, the polluted soil is positioned between the two buckets (13), and the stirring rod (19) continuously operates to further mix the medicament with the polluted soil;

step three: if the polluted soil is purified, two buckets (13) are opened, the soil is poured out, and if the pollution is serious, the soil needs further treatment, the two buckets (13) are kept closed, the whole device is closed, the frame (1) is pushed, and the whole device is transported with the soil needing further treatment for further treatment.
