The invention discloses a trichloroacetaldehyde soil pollution treatment device. The left end of a corrugated pipe is fixedly connected with a bucket, the upper end of the bucket is fixedly connectedwith an air pressure telescopic rod, and the air pressure telescopic rod is fixedly connected with a device body; and a medicament tank is arranged at the left end of the upper part of a sleeve, the right end of the medicament tank is fixedly connected with a conduit, and the upper part of the left end of the medicament tank is fixedly connected with a drug injection tube, the upper part of the right end of the medicament tank is fixedly connected with a gas guide tube, and the middle part of the gas guide tube is fixedly connected with an air compression pump, and the air compression pump iselectrically connected with a power box. According to the trichloroacetaldehyde soil pollution treatment device, a rotary tillage roller is driven by engine wheels to rotate so as to drive soil digging blades to plough soil, a swing arm can control the height of the rotary tillage roller so that the soil digging depth can be adjusted, soil loosening effect is good, the soil is transported upwardsthrough a spiral lifting rod and is mixed with an alkaline fertilizer, the soil and the fertilizer are fully mixed by stirring teeth, and treatment is more thorough; and the trichloroacetaldehyde soilpollution treatment device has the advantages of being reasonable in structural design, treatment effect of the organic pollutant trichloroacetaldehyde soil pollution is greatly improved, so that theenvironment is facilitated.
