【Abstract】 In this article, the centennial technology development of urban wastew ater treatment was reviewed, the recent advances were discussed and it is believed that the general trend of wastewater treatment process is to shorten and to simplify the technologic scheme. In addition, the integral wastewater treatment technologies are discussed. It is indi-cated by the author s that the integral oxidation ditch is distinctive. There are no problems of allocation; it is a mono-space continuous operation system with high ration of volume utilization. There is a good development prospects for the integral oxidation ditch.更多还原
