摘要:

介绍了循环式活性污泥法 (CAST)的工作原理,概述了国内外关于循环式活性污泥法在城市及工业废水处理中的操作运行条件及实际应用现状。认为循环式活性污泥法将 SBR工艺和生物选择器的原理结合在一起,具有防止污泥膨胀、强化脱氮除磷效果、耐冲击负荷等显著特点。在城市生活污水、工业有机废水,尤其是含氮、磷工业废水处理中有良好的研究开发价值和广阔的推广应用前景。

关键词: 循环式活性污泥法, 生物选择器, 废水处理

Abstract:

The principle of Cyclic Activ ated Sludge Technology ( CAST ) is introduced.The research about the operation, running conditions and its application of CAST to the treatment of municipal and industrial was tewater are reviewed.It is thought that CAST which combines the SBR with abiological selector has no table advantages such as filamentous sludge bulking control,co-current nitrification/denitrification,enhanced biological phosphorus removal and good resistance to shock load, etc.The application prospects of CAST should be widely popularized and given energetic study and development to the treatment of municipal was tewaters and industrial organic wast ewaters,especially to the treatment of nitrogen and phosphorus containing industrial was tewater.

Key words: cyclic activated sludge technology, biological selector, wastewater treatment
