摘要
介绍了采用间歇式活性污泥工艺（ＳＢＲ）处理聚酰胺废水的生产运行实验。运行结果证明：当进水ＣＯＤ，ＮＨ３－Ｎ和聚酰胺物质的质量浓度分别为２ ９０１～３ ９２３，２０１～２２３，１ ５０４～１ ６３６ ｍ ｇ／Ｌ时，出水ＣＯＤ，ＮＨ３－Ｎ和聚酰胺物质的质量浓度分别为９８～１１７，１４．５～２４．６，２５．７～４１．８ ｍ ｇ／Ｌ，去除率分别为９７％ ，９１％ 和９８％ 。采用该工艺处理聚酰胺废水具有投资少、运行稳定、处理效果好、运行费用低等特点。
The polymide processing wastewater treatment by sequenching batch reactor (SBR) was introduced.The results showed that the influent COD,NH 3 N and polyamide were 290 1~ 3 923 mg/L,201~223 mg/L and 1 504~1 636 mg/L respectively,the effluent COD,NH 3 N and polymide were 98~117 mg/L,14.5~24.6 mg/L and 25.7~41.8 mg/L respectively,the 97%,91%and 98% of removal rate of COD,NH 3 N and polyamide were reached respectively.SBR has the advantages such as low investment,low operation cost and high removal efficiencies etc.
