Solar-driven　interfacial　evaporation　stands　out　as　a　low-energy,　environmentally-friendly　desalination　approach　with　substantial　potential　for　clean　water　recovery　and　resource　harvesting.　However,　the　stability　of　the　system　is　compromised　by　an　undesirable　increase　in　salt　accumulation.　Herein,　we　designed　a　modular　structure　to　separate　functional　areas.　The　whole　structure　contains　an　evaporator　and　a　collector:　the　evaporator　mainly　takes　on　the　function　of　evaporation　and　the　collector　is　mainly　used　for　the　crystals　collection.　Operating　under　one　sun　illumination,　the　system　attained　a　high　evaporation　rate　of　2.34　kg　m-2h-　1　and　a　high　solar-water　evaporation　efficiency　of　133.19　%.　Owing　to　the　replaceable　collector,　the　evaporation　system　maintained　a　consistently　high　evaporation　rate　even　after　240　h　of　continuous　operation,　and　up　to　97　%　of　the　solute　was　enriched　in　the　collector.　Furthermore,　we　investigated　the　impact　of　natural　organic　matter　(NOM)　on　both　evaporation　and　crystallization　within　the　system.　This　study　provides　a　new　perspective　on　the　design　of　solar　interfacial　evaporation　and　crystallization　systems.
