城市污水处理与一体化氧化沟技术

Integral Oxidation Ditch for Urban Wastewater Treatment

纵观百年城市污水处理技术的发展 ,通过对近年来污水处理新技术和运行方式的分析 ,提出现代污水处理技术发展总趋势是缩短和简化工艺流程 ,并对污水处理一体化技术作出分析和讨论 ,提出一体化氧化沟技术不同之处是不作时间和空间调配。一体化氧化沟单空间连续工作 ,容积利用率高 ,有较好的发展前景。

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.
