【摘要】 通过用高效好氧生物法处理某厂印染废水的工程实例证明,处理后的废水COD去除率达到93.6%,BOD5去除率达到93.9%,出水水质能够满足GB4287—1992《纺织染整工业水污染物排放标准》二级标准的要求。该工程工艺的优点为:基建费用低,空气氧转化利用率高,容积负荷和污泥负荷高,剩余污泥量少,抗冲击负荷能力强,系统操作简便灵活。更多还原

【Abstract】 The case study of textile wastewater treatment by a highly efficient aerobic biological process in a dyeing and printing plant indicates that the removal rates of the COD and BOD5 of the treated wastewater have reached the Grade Ⅱ Standard of Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry (GB 4287—1992) - they are 93.6% and 93.9%, respectively. The process has the following advantages: low cost of construction, high transformation and utilization rates of oxygen, high loads of cubage and sludge, little residual sludge production, strong resistance to impact and easy operation.更多还原
