【摘要】 采用厌氧水解酸化──好氧生物处理──生物活性炭──纤维球过滤的工艺流程处理印染废水。试验研究表明：该流程对ＣＯＤｃｒ的去除率达８９％以上，出水ＣＯＤｃｒ、ＢＯＤ５、色度分别为１９６．７８ｍｇ／Ｌ、３２．５ｉｎｇ／Ｌ、４６（稀释倍数），达到国家排放标准，水解酸化池可将印染废水的可生化性（ＢＯＤ５／ＣＯＤｃｒ）由０．２６提高至０．５０。更多还原

【Abstract】 The technological process seqence of 2-stage anaerobic-3-stage anaerobic reacters-BAC column-fibreball filter is adopted to treat the printing-dyeing wastewater.Experimental study shows that, its CODer reduction rate may exceed 89%.and the CODcr concentration of effluent is 196,78mg/L,BOD5 32,5mg/L,colour 46 (dilutionfactor),able to meet the National discharge Standard.The biodegradsbility (BOD5/CODcr) of printing-dyeing wastewater can be found increasing from 0.26 to 0,50 in the anaerobic tank.更多还原
