Abstract:

Aeration and no aeration are used in catalystic iron inner electrolysis(CIIE) process for dyeing wastewater treatment respectively. The pretreatment effect on the wastewater is indicated by various of indexes such as COD, colority, phosphate, ammonia-nitrogen, pH etc. The results of the experiments show that the removing COD, colority and phosphate in wastewater are remarkably efficient. The CIIE process with aeration is better than the process without aeration.

Key words: dyeing wastewater, catalystic iron inner electrolysis, aeration

摘要：

针对实际印染废水,采用催化铁内电解法进行曝气与不曝气两种不同处理工艺对比试验,测定了处理前后废水的COD、色度、磷酸盐、氨氮、pH等指标。结果表明,曝气催化铁内电解工艺优于不曝气的工艺,对废水中COD、色度和磷酸盐的去除有显著提高。
