| 摘 要： | 随着我国政府不断加大对环境保护的力度,我国城镇污水处理厂数量呈现逐年增加的趋势,2008年之后增长迅速。我国污水处理厂工艺使用最多的主要有氧化沟、A/A/O以及活性污泥工艺,市场占比分别为30.50%、16.20%和9.50%,工艺分布具有明显的地域性。城镇污水处理厂中,设计规模为1万～5万t/d的占50%以上,小规模化将是未来发展趋势之一。随着污水厂数量逐渐增多并达饱和后,势必要在提高出水水质上做出努力,同时伴随而生的污泥问题也日益严峻。因此,需结合提升污染物排放限值的手段和污泥处理处置技术,将污水、污泥处理处置共同推进。

| Abstract: | With strengthening environmental protection by Chinese government,number of urban sewage treatment plants have shown a rising trend,and they grow rapidly after 2008.It was found that the most used processes of sewage treatment plants are oxidation ditch,the A/A/O and activated sludge process with the market share of 30.50%,16.2% and 9.50%separately.The processes have obvious regional characteristics.Design scale of 1×104 to 5×104 t/d occupies more than 50%,which speculates that small scale of urban wastewater plant will be one of development trends in the future.As the gradual increase in the number of wastewater treatment plants,it is bound to make efforts to improve water quality.At the same time,sludge problem accompanied is increasingly serious.Therefore,enhancing emission limits of pollutants and using sludge treatment and disposal technology can promote the treatment of wastewater and sludge. |
