“抗生素发酵废水硫自养泥法深度脱氮除碳技术”成果通过中国环保产业协会鉴定

2022-07-27 08:33:15来源:中国环保产业协会 阅读量:14227

导读:近日,中国环境保护产业协会组织召开了华南理工大学和浦城正大生化有限公司共同申请的“抗生素发酵废水硫自养泥法深度脱氮除碳技术”成果鉴定会,技术成果顺利通过鉴定。
  近日,中国环境保护产业协会组织召开了华南理工大学和浦城正大生化有限公司共同申请的“抗生素发酵废水硫自养泥法深度脱氮除碳技术”成果鉴定会,中国环境科学研究院宋乾武研究员担任鉴定委员会主任。
 
  该成果针对抗生素发酵废水高氨氮、高有机物、高毒性、难降解性、碳氮比低、处理难度大等问题,以低碳、环保为目标,筛选出具有特定功能的生物菌种,开发了泥法硫自养反硝化技术(MSAD)与好氧同步短程氨氧化技术(SND)相耦合的脱氮技术,通过对传统AO工艺的原位改造,实现了差异化碳源下的深度脱氮,并形成了完整的抗生素废水活性污泥法生物处理工艺技术及工程设计、运行管理规程。
 
  “抗生素发酵废水硫自养泥法深度脱氮除碳技术”成果硫磺用量少,启动时间短。
 
  同时,突破了传统好氧反应工艺单元脱氮的单一硝化作用,在系统中实现了短程同步硝化、亚硝化和反硝化,形成了短程同步好氧氨氧化,实现了低碳氮比废水的深度脱氮。
 
  该工艺适用于抗生素发酵类废水处理以及其他行业高浓度有机废水和高氨氮废水的深度脱氮处理,具有广泛的应用潜力;工艺兼容性强,可与现有的活性污泥法生物脱氮系统有效衔接,可广泛用于现有约 90%以上的污水处理脱氮设施的改造。
 

 

  该成果已在浦城正大2000m3/d抗生素发酵废水项目中应用,运行过程中不需要外部投加碳源,与传统工艺相比,脱氮成本降低了98%,运行总成本降低20%以上,剩余污泥产生量减少50%。
