Municipal sewage and organic waste water have been treated by biological treatment methods such as activated sludge system in general. But, it takes so long period to treat the sewage and the removability of total nitrogen(TN) and total phosphorus(TP) is not sufficient. In resent year, the treatment system which can remove TN, TP, suspended solids, BOD and TOC in short period and its maintenance easy are required to prevent eutrophication of environmental water. We developed the following system as an high rate and advanced sewage treatment system. The system consists of the coagulation-foam separation process(hydraulic retention time HRT:0.15hr), BOD removal process (HRT:1.5hr), nitrification process (HRT:1.5hr), and de-nitrification process(HRT:3hr). The BOD removal process, nitrification process, and de-nitrification process contain the media of Bio-tube produced by NKK Co.. Total treatment period is 6.15hr. The treated effluent quality (and removal %) of Kibana sewage plant in Miyazaki City effluent of sedimentation tank was turbidity:5.11TU(89.3%), SS:6.2mg/L(84.2%), BOD:7.1(91.0%), TOC:4.5mg/L(89.3%), TN:2.78mg/L(91.3%), and TP:0.14mg/L(92.3%). These removability are better than the advanced sewage treatment system which is used in our country resent years. And total treatment period is only 1/3 of that system. Therefore, the advanced municipal sewage treatment system which was developed in this research is considered to be very effective and useful to treat municipal sewage and organic wastewater.

城市污水和有机废水一般采用活性污泥法等生物处理方法进行处理。但是，污水处理周期长，总氮（TN）和总磷（TP）的去除率不高。近年来，为防止环境水体的富营养化，要求处理系统能在短时间内去除TN、TP、悬浮物、BOD和TOC，且易于维护。我们开发了以下系统作为一个高效率和先进的污水处理系统。该系统由混凝-泡沫分离工艺（水力停留时间HRT：0.15hr）、BOD去除工艺（HRT：1.5hr）、硝化工艺（HRT：1.5hr）和反硝化工艺（HRT：3 hr）组成。生化需氧量去除工艺、硝化工艺、反硝化工艺采用NKK公司生产的生物管介质。总治疗时间为6.15小时。宫崎市污水处理厂沉淀池出水浊度5.11TU（89.3%），SS 6.2mg/L（84.2%），BOD 7.1（91.0%），TOC 4.5mg/L（89.3%），TN 2.78mg/L（91.3%），TP 0.14mg/L（92.3%）。其去除效果均优于我国近年来使用的污水深度处理系统。总处理时间仅为该系统的1/3。因此，本研究所开发的城市污水深度处理系统对城市污水和有机废水的处理是非常有效和实用的。
