The invention discloses a spinning printing and dyeing waste water reclamation method, a device and the application thereof. The method comprises the steps of: filtering spinning printing and dyeing waste water; sequentially carrying out homogenizing, equalizing quantity and primary sedimentation on filtrate; adding sodium chloride into waste water supernate, and evenly mixing for indirect electro-catalysis oxidation; sequentially evenly mixing the waste water treated by indirect electro-catalysis oxidation with basic aluminium chloride and polyacrylamide; removing the precipitated supernate, and sequentially treating by activated carbon adsorption and reverse osmosis; removing trace organic chloride generated in the electrolytic process and the rest COD and color; and obtaining recyclable water resource. The device for realizing the method comprises a grate, a regulating reservoir, a sealed electrolytic cell, a flocculation tank, an inclined tube sedimentation tank, a sand filter tank, an active carbon filter, an intermediate water tank, a reverse osmosis unit, a clear water reservoir, a brine tank, a chlorine absorbing tank, a sludge concentration tank and a plate-and-frame filter press. The invention can effectively treat spinning printing and dyeing waste water, and has the advantages of high treatment efficiency, stable effluent quality, simple technological process and the like.
