中国城市污水处理工艺及应用
摘要
本文介绍中国水污染及处理现状分析,国内外常用以及新兴的污水处理工艺,部分工艺的应用实例。我过城市污水处理厂的发展趋势:具有脱氮除磷功能的污水处理工艺仍是今后发展的重点;高效率、低投入、低运行成本、成熟可靠的污水处理工艺是今后污水处理厂的首选工艺;对适用于小城镇污水处理厂工艺的研究;对产泥量少、且污泥达到稳定的污水处理工艺的研究。
关键词:水污染污水处理工艺脱氮除磷污水处理厂
China Urban Sewage Treatment Technology and Application
Abstract
This article describes the current situation of water pollution and treatment, domestic and mon and emerging wastewater treatment process, part of the process of application examples. Urban sewage treatment plant trends: a function of nitrogen and phosphorus removal wastewater treatment process is still the focus of future development; high efficiency, low investment, low operating cost, mature and reliable sewage treatment process is the future technology of choice for wastewater treatment plant; Applicable to small-town sewage treatment plant in the research process; on the production of less sludge and sewage sludge treatment process to stabilize the research.
Key words: water pollution, sewage treatment process, nitrogen and phosphorus removal, sewage treatment plant
