摘要：A printing and dyeing wastewater treatment and reuse apparatus includes acoarse filter, a regulation pool, a hydraulic sieve, a desulfurization pool, a nanocatalyticelectrolyzer, a flocculation pool, a flocculation tank, a settling pool, a flotation device, a

biochemical pool, a secondary settling pool, a secondary nanocatalytic electrolyzer, a finefilter, a compressor, a nanomembrane assembly, and a recycling pool. Also provided is aprinting and dyeing wastewater treatment and reuse method including steps of

desulfurization, nanocatalytic electrolysis, flocculation, biochemical treatment, secondarycatalytic electrolysis, filtration, and separation by membrane. The invention allows highCODremoval rate, reduced chemical agent consumption, reduced sludge formation,thorough treatment, and high water reuse rate.
