The invention relates to the technical field of seawater desalination, in particular to a low-temperature multi-effect distillation seawater desalination system, which is used for increasing the seawater concentration rate. The Low-temperature multi-effect distillation seawater desalination system comprises a plurality of tandem evaporation sets with a reverse flow sequence and a direct flow sequence, a condenser communicated with the evaporation set with lowest running temperature in the reverse flow sequence, a seawater feeding pipeline communicated with the condenser, a steam feeding pipeline communicated with the evaporation set with highest running temperature in the direct flow sequence, and inter-group water pumps arranged on inter-group seawater pipelines. According to the low-temperature multi-effect distillation seawater desalination system, the tandem evaporation sets are divided into the reverse flow sequence and the direct flow sequence, a raw material-seawater enters the evaporation sets with th
