随着污水排放标准的逐渐提高，城镇污水处理厂的提标改造工程势在必行。污水处理厂提标改造路线包括生化池改造、增加深度处理以及两者结合实施。介绍了目前主要的生化池改造措施如主体工艺中镶嵌MBBR工艺增强脱氮作用，将传统活性污泥工艺改造成能够同步脱氮除磷的工艺等；深度处理主要采用增加滤池且辅以化学加药进一步去除SS、TP等指标。为我国的污水处理厂提标改造工程提供了技术方向和参考。

With the increasing standards for sewage discharge, it is imperative to upgrade and renovate urban sewage treatment plants.The upgrading and renovation routes for sewage treatment plant include the renovation of biochemical tank, the increase of advanced treatment and the combination of the two.Current main renovation measurements for biochemical tank are introduced, such as the embedded moving bed biofilm reactor (MBBR) process in the main process to enhance denitrification effect, and the transformation of traditional activated sludge process into a process that can simultaneously remove nitrogen and phosphorus.Advanced treatment mainly adopts an additional filter and further removes SS, TP and other indicators with supplement of chemical dosing.It is expected to provide technical direction and reference for future sewage treatment plant upgrading and renovation projects in China.
