摘要
常温条件下,采用混凝-A/O(兼氧/好氧)-气浮组合工艺处理含PVA浆料的高浓度印染废水的工程实例研究。结果表明:常温下含PVA印染废水经该工艺处理后COD cr去除率达95%,SS去除率达91%,色度去除率达90%以上,该工艺具有能提高废水可生化性、脱色效果好、处理效率高、耐冲击性能好、操作管理方便的特点。
The progress of treatment of dyeing wastewater containing PVA by anoxic-oxidation bio-attachment with flotation technology were described. The results showed that ,under ambient temperature ,the technologies could achieve a high CODcr removal efficiency of 95% and the removal efficiency of SS and color were 91%and 90% respectively. This technologies compared with other bio-treatment has a lot of advantages such as high color and CODcr removel efficiency ,ability of high bio - attachment.
