摘要

分析了石家庄化纤公司己内酰胺生产废水的水质状况,指出该废水属高含氮、高浓度有机废水,虽然可生物降解性能较好,但因处理水在好氧硝化池(O1)中水力停留时间不够,难以达到硝化阶段,导致了原有生物处理工艺A/O/A/O系统无法正常运行。根据生物脱氮原理,提出了以SBR法作为处理工艺主体的ENSBR/BDAR/PCOR三段生物处理工艺。实验数据和生产运用表明,高含氮高浓度有机废水经该工艺处理后出水水质达到国家二级排放标准要求。

Abstract

The wastewater quality at Shijiazhuang Fiber Co.,Ltd.hasbeen analysed.The resultsof the analysisshow that the wastewater containsboth highly concentrated nitrogen and organic matters.Although the wastewater issuitable for biological treatment,the HRT of the wastewater in the first aerobic nitrification reactor(O 1)staysso short that the nitrification doesn ' t have enough time to take place,which resultsin the failure of the existing A/O/A/O biological treatment.Based on the biological nitrogen removal principle,thisstudy hasput forward three-stage biological treatment techniques,i.e.ENSBR/BDAR/PCOR with the SBR being the principle method.The laboratory data and production practice have shown that the effluent wastewater from ENSBR/BDAR/PCOR isin compliance with Grade2Standardsof the National Wastewater Discharge requirements.
