摘要
活性污泥法是目前处理污水的一种有效方法,在应用过程中,频频发生的污泥膨胀现象成为影响污水处理效率的难题,对污泥膨胀进行早期预警调控研究,已成为该领域关注的热点问题.本文阐述了丝状菌引起的污泥膨胀预警研究的进展情况,从污泥常规指标测定、形态观察和分子生态学3个方面对丝状污泥膨胀的预警方法进行了综述,对各种方法的优点与不足展开讨论,并在此基础上归纳出一些改进的措施,展望了丝状污泥膨胀预警的应用前景.
Activated sludge method is effective method in the treatment of wastewater,but the sludge bulking in the application of this method will affect the efficiency of wastewater treatment.The pre-warning and controlling of sludge bulking have been a hot topic in this field.In this paper,the latest developments in the pre-warning of sludge bulking are represented,and pre-warning methods of sludge bulking through the determination of the conventional sludge indicators,observation of morphologic and molecular ecology are comprehensively described.The advantage and disadvantage of various methods are discussed.Based on the discussion,some modified methods are concluded.Moreover,the application prospects of the sludge bulking pre-warning methods are previewed.
