| 摘 要： | 纺织洗布废水具有较高的COD,浊度,电导率,处理此类废水一般都采用普通的生化处理使其达标排放。采用臭氧-曝气生物滤池(BAF)组合工艺对广东某纺织品有限公司洗布废水的生化处理出水进行深度处理以达到企业确定的回用标准。经试验表明:臭氧投加量为30mg/L时,深度处理系统的COD去除率超过62.5%,出水COD控制在30mg/L以下,浊度<1NTU,完全达到企业确定的回用标准。纺织洗布废水回用新工艺具有处理成本很低,处理效果稳定,具有显著的环境效益和经济效益。

| Abstract: | Textile washing wastewater which has higher concentration of COD,turbidity and conductivity can be treated by ordinary biochemical process to discharging standard.The ozonizing biological aerated filter(BAF)process was used to treat washing wastewater after biological treatment in a textile works of Guangdong,results indicated that when the ozone dosage was 30mg/L,removal efficiency of COD was above 62.5%,and effluent COD was less than 30mg/L,turbidity less than 1 NTU,which completely satisfied the reusing ... |
