摘要
棉浆粕生产综合废水的生化—物化处理试验表明，采用驯化活性污泥法可有效地去除废水中易生物降解的有机物。当浆粕废水进水ＣＯＤｃｒ浓度１２００～１８００ｍｇ／Ｌ范围内，ＣＯＤｃｒ负荷１．８～２．８ｋｇ／ｍ３·ｄ时，ＣＯＤｃｒ去除率可达５８％～６４％，ＢＯＤ５去除率可达８５％～８９％。生化出水经投加化学混凝剂进行物化处理后，ＣＯＤｃｒ可进一步去除６５％～７５％左右。
The microbial degradation with aerobic process was investigated to characterize the biodegradability of the cotton pulp wastewater with CODcr concentration 1200￣1800 mg/L the aerobic process results in good removal of BOD5(85%￣89%) and CODcr(58%￣64%) respectively.And subsequently chemical precipitation results in more removal of CODcr(63%￣70%) when proper chemicals are added.
