Fischer-Tropsch synthesis waste water treatment system for coal fine chemical products

The invention discloses a Fischer-Tropsch synthesis waste water treatment system for coal fine chemical products. The Fischer-Tropsch synthesis waste water treatment system for coal fine chemical products comprises a collecting water pond, a smoothing oil separator, a water collecting tank, ceramic nano-filtration equipment, a filtered water tank, an alcohol separating tower and a comprehensive adjusting pond. The Fischer-Tropsch synthesis waste water treatment system for coal fine chemical products has the advantages that contents of catalyst powder particles, heavy wax and oil slick in Fischer-Tropsch synthesis waste water are removed by the smoothing oil separator, and the purchase expenses for change of a blocked filter element of downstream filter equipment is saved; one part of dealcoholized Fischer-Tropsch synthesis waste water is fed to a chilled water tank and is used as supplemented chilled water for a gasification unit-a scrubber tower, the other part of dealcoholized Fischer-Tropsch synthesis wast
