摘要
活性污泥工艺是污水处理的主要工艺 ,传统的活性污泥工艺采用中等污泥负荷 ,曝气池为连续推流式。对传统工艺的改进可以充分满足各种不同的处理要求 ,这些改进可以分为池形的改进、运行方式的改进、曝气方式的改进、生物学方面的改进及投加填料等方面的改进。本文从工艺改进和污泥膨胀两个方面介绍了活性污泥工艺的技术发展 。
The activated sludge technology is a major technique for sewage treatment. Medium sludge load and continuous push flow aeration tank are adopted in the traditional activated sludge technology. The requirements of different treatment processes can be fully met through improvements on the traditional technology. Such improvements include tank shape, operation mode, aeration mode, biological aspect and packing addition. In this article technical developments of the activated sludge technology in process improvement and sludge expansion are introduced and its future development trend is also discussed.
