| 摘 要： | 目前中水厂处理采用的基本工艺对去除污水中氮的效果不好，易造成水体富营养化。由于中水厂出水中氮的含量相对较低，属于微污染水，不适合采用化学方法进行去除，要去除这种水质中的氮考虑采用生物法脱氮。本项目先研究了在慢滤状态，陶粒生物慢滤池对氮的去除效果，继而改进实验装置在慢滤池后加入碎石曝气段及石英砂快滤段，有效地提高了氮的去除效果，氮的去除率基本上都在14％以上，最好时对氨氮去除率可达到28．57％以上。

| Abstract: | These days,the effect of the basic treatment techniques of intermediate water is not good,which is used by sewage treatment plant to remove nitrogen,which lead to the eutrophication of water bodies easily.Chemical methods are not suitable to get rid of nitrogen from intermediate water,which is micro-polluted water and the content of nitrogen is relatively low.Bio-denitrification is an effective way.The removal of nitrogen is studied by using slow ceramic filtration in slow water filter in this experiment.In... |
