原生动物在水质净化过程中的应用与发展

Application and Development of the Protozoans during Water Purification

原生动物是水质净化过程中重要的组成部分,研究原生动物在水质净化方面的应用与发展已成为研究热点。首先阐述了原生动物的概念、营养类型、分类和研究目的,并在此基础上分析了原生动物在水质净化过程中的生态演替、指示作用、预测出水水质及强化净化效果等方面的特性;最后从原生动物种群动态与水质变化的相互关系、原生动物污泥减量化效果和食藻类原生动物在治理蓝藻水华中的应用等方面分析了原生动物在水质净化领域的研究方向。

The protozoans are important constituent parts of water purification treatment system, and investigation of the functions of protozoans during water purification has been research focuses. The first part of this paper introduces the protozoan conception, nutrition type, classification and study purpose. Then, the performances of ecological succession, indicator, prediction of effluent quality and enhancement of the purifying efficacy of protozoans during water purification are analyzed. Lastly, three functions of protozoans, involving prediction of different water quality parameters according to the different protozoan species, sludge reduction and eat algae using protozoans, are analyzed.
