“抗生素發酵廢水硫自養泥法深度脫氮除碳技術”成果通過中國環保產業協會鑒定

導讀:近日,中國環境保護產業協會組織召開了華南理工大學和浦城正大生化有限公司共同申請的“抗生素發酵廢水硫自養泥法深度脫氮除碳技術”成果鑒定會,技術成果順利通過鑒定。
  近日,中國環境保護產業協會組織召開了華南理工大學和浦城正大生化有限公司共同申請的“抗生素發酵廢水硫自養泥法深度脫氮除碳技術”成果鑒定會,中國環境科學研究院宋乾武研究員擔任鑒定委員會主任。
 
  該成果針對抗生素發酵廢水高氨氮、高有機物、高毒性、難降解性、碳氮比低、處理難度大等問題,以低碳、環保為目標,篩選出具有特定功能的生物菌種,開發了泥法硫自養反硝化技術(MSAD)與好氧同步短程氨氧化技術(SND)相耦合的脫氮技術,通過對傳統AO工藝的原位改造,實現了差異化碳源下的深度脫氮,并形成了完整的抗生素廢水活性污泥法生物處理工藝技術及工程設計、運行管理規程。
 
  “抗生素發酵廢水硫自養泥法深度脫氮除碳技術”成果硫磺用量少,啟動時間短。
 
  同時,突破了傳統好氧反應工藝單元脫氮的單一硝化作用,在系統中實現了短程同步硝化、亞硝化和反硝化,形成了短程同步好氧氨氧化,實現了低碳氮比廢水的深度脫氮。
 
  該工藝適用于抗生素發酵類廢水處理以及其他行業高濃度有機廢水和高氨氮廢水的深度脫氮處理,具有廣泛的應用潛力;工藝兼容性強,可與現有的活性污泥法生物脫氮系統有效銜接,可廣泛用于現有約 90%以上的污水處理脫氮設施的改造。
 

 

  該成果已在浦城正大2000m3/d抗生素發酵廢水項目中應用,運行過程中不需要外部投加碳源,與傳統工藝相比,脫氮成本降低了98%,運行總成本降低20%以上,剩余污泥產生量減少50%。
