分段进水多级AO同步脱氮除磷工艺及应用

摘要

The research,development and engineering application of the new process simultaneous removal of nitrogen and phosphorus have already been more and more valued by the sewage treatment industry. With the help of the prac-tice of the sewage treatment plant in Liaohe governance project—Linghai sewage treatment plant,Show a new process, it is as well as simultaneous removal of N and P,the step-feed multistage A-O process. It is hoped that it will accumulate the experience for spreading and applying the process in the sewage treatment industry.%近年来，同步脱氮除磷处理新工艺的研究、开发和工程应用越来越受到污水处理界的重视。通过辽宁省辽河治理项目凌海市污水处理厂的建设实践，介绍了一种兼具同步脱氮除磷功效的崭新工艺—分段进水多级AO工艺，以期能为该技术在我国污水处理行业的推广应用积累经验。
