活性污泥中原生动物的特征和作用

Characteristics and Functions of Protozoa in Activated Sludge Process

污水处理厂的处理效果主要取决于水中的微生物。原生动物能用来改善水质、评价和指示污水厂的运行和处理效果。根据原生动物的生物特征及其在不同环境条件下的种属、数量、活性等表现 ,通过其组成和数量的分析 ,可以迅速为活性污泥工艺提供有益的指示信息 ,从而指导污水厂的生产运行。

Microorganisms living in the water of wastewater treatment plants are responsible for the effluent quality. Protozoa could be used to improve the effluent quality, evaluate and assess the operating and function of the waste^water treatment plant. Based on the biological characteristics and principles, by analysis of the structure and number of protozoa, we can quickly get useful information on the activated sludge process, and subsequently give directions to the performance.
