Snow melting agent-containing snow water purifying, recycling and circularly utilizing process and system

The invention relates to one of the key contents to be considered in the construction of sponge city in the northern region, namely, the technical field of sponge city snow melting in the northern region, in particular to a snow melting agent-containing snow water purifying, recycling and circularly utilizing process and a snow melting agent-containing snow water purifying, recycling and circularly utilizing system. The system comprises a raw material salt water tank, an evaporator, a separator, a crystallizing tank, a centrifugal machine, a spiral conveyer, a vibrating fluidized bed dryer, anair heater, a heat exchanger, a compressor, a water pump, a circulating pump, a fan and a pre-heater. The process and the system have the beneficial effects that snow melting salt is recycled from snow melting agent-containing snow water by adopting an evaporating crystallizing process, so that the damage to the environment caused by the snow melting agent-containing snow water can be reduced remarkably, and the influenc
