活性污泥法水处理的研究

我国是世界上淡水资源严重缺乏的国家，被列为全球最缺水的13个国家之一，同时我国又是一个淡水资源被严重污染的国家。因此，污水净化以及净化水的有效重复利用就成为我国急需解决的一项战略性问题。污水生物处理是目前应用广泛、处理效果好而且经济的一种水处理方法。活性污泥法是其中的代表，在活性污泥上栖息、生活着大量的微生物，这些微生物以溶解性有机物为食料，获得能量，并不断增长繁殖，从而使废水得到净化。

Wastewater Treatment by Activated Sludge Process

China is one of the 13 countries in the world which lack of freshwater resources critically, and not only that, in which the freshwater is also polluted seriously. So the purification and repetitious utilization of water become the strategic issues which are in dire need of solution. At present, biological wastewater treatment are frequently used as it is effective and economy. Activated sludge is the typical method. In the activated sludge there are many microorganisms which live on the dissolved organic in the wastewater and gain energy to grow. And the wastewater is purified consequently.
