<p>A printing and dyeing wastewater treatment and reuse apparatus. The apparatus has sequentially arranged therefor a bar screen filter (1), a retention pool (2), a hydraulic sieve (3), a desulfurization reaction pool (4), a nanometer-catalyzed electrolyzer (5), a flocculation reaction pool (6), a sedimentation pool (7), an floatation apparatus (8), a biochemical pool (9), a secondary sedimentation pool (10), a secondary nanometer-catalyzed electrolyzer (11), a filter (12), a compressor (13), a membrane system (14), and a recycling pool (15). Also provided is a printing and dyeing wastewater treatment and reuse method. The method comprises the steps of desulfurization, nanometer-catalyzed electrolysis, flocculation, biochemical treatment, secondary catalyzed electrolysis, filtration, and separation by membrane. The method allows for high CODCr removal rate, reduced chemical agent consumption, reduced sludge production, thorough treatment, and high water reuse rate.</p> |
