摘要
结合某氨纶企业废水处理工程的废水水质特点及出水水质和回用水质要求,新增加了浓水预处理系统,提出了预酸化/厌氧/AO/反硝化滤池/多介质过滤/活性炭过滤/RO的处理工艺,解决了废水处理以及回用的问题。详细介绍了改造工程方案及其实际运行效果。该工程对COD和氨氮的去除率分别达到97.5%和98%以上,出水水质稳定达到《污水综合排放标准》(GB8978—1996)的一级标准。回用水水质优于《城市污水再生利用工业用水水质》(GB/T 19923—2005)工业循环冷却水标准。
According to the quality characteristics of spandex production wastewater from a span- dex enterprise and the requirements for the effluent quality, and reuse water quali~, a concentrated water pretreatment system was added and a combined process of pre-acidification/anaerobic/AO/denitrification fiher/muhi-media filtration/activated carbon fiher/RO was put forward. The reconstruction scheme and the actual operation results of the wastewater treatment project were elaborated. The results showed that the removal rates of COD, ammonia nitrogen could reach 97.5% and 98% above. The final effluent could reach first level criteria of Integrated Wastewater Discharge Standard （ GB 8978 - 1996） and the re- used water was better than The Reuse of Urban Recycling Water--Water Quality Standard for Industrial U- ses （ GB/T 19923 - 2005 ）.
