The utility model relates to the technical field of environmental protection, in particular to an environment-friendly snow removing, melting and harmless treatment integrated device and a working method thereof. A vertical spiral shaft and a transverse spiral shaft are arranged in a snow pushing shovel; the conveying belt is arranged in the conveying pipeline and is connected with the vertical spiral shaft; the snow removal power vehicle water tank and exhaust pipe waste heat utilization system comprises a power vehicle exhaust pipe, a power vehicle water tank, a heat exchanger and a flowingmedium pipe. The flowing medium pipe passes through a conveying pipeline. The heat preservation operation chamber is a cuboid corrosion-resistant alloy container with a heat preservation layer on theinner wall, a feeding port is formed in the front end, a scraping plate is arranged at the upper end, double doors are arranged at the tail end, and a conical precipitation tank and a sludge dischargevalve are arranged at the bottom end; a steam heater, a microwave heater, a dosing system and a spraying system functional unit are arranged in the heat preservation control chamber. According to thesnow remover, accumulated snow does not need to be piled up or transported for a long distance, the accumulated snow is directly melted into snow water to be discharged on site, and therefore snow removing, snow melting and harmless treatment can be achieved through one dragon type operation.
