生物废水处理系统中指示性微型动物研究现状

Research Status of Indicative Microanimals in Biological Wastewater Treatment System

污水处理净化系统中微型动物对水质环境变化比较敏感并且容易观察,常被人们用来作为监测污水处理净化效果的指示性微型动物,指示性微型动物的监测对快速实时准确掌握水质净化效果,具有十分重要的指导作用。本文首先阐述了指示性微型动物的基本概念和特点,在此基础上总结了指示性原生动物和后生动物的种类以及污水厂中常见的指示性微型动物。其次从指示性微型动物优势种、群落、形态、繁殖方式与水质变化的相互关系等方面分析了指示性微型动物在污水处理方面的应用,最后总结了不同因素对指示性微型动物的影响,为污水处理厂利用指示性微型动物预测水质变化提供参考。

The micro-animals in the sewage treatment and purification system are sensitive to changes in the water quality environment and are easy to observe.They are often used as indicative micro-animals to monitor the purification effect of sewage treatment, having important guiding role. This article first explains the basic concepts and characteristics of indicative microfauna, and on this basis summarizes the types of indicative protozoa and metazoa, as well as common indicative microfauna in sewage plants. Secondly, it analyzes the application of indicator micro-animals in sewage treatment from the aspects of dominant species, community,morphology, reproduction mode and water quality changes of indicator micro-animals, and finally summarizes the influence of different factors on indicator micro-animals. Sewage treatment plants use indicative micro-animals to provide reference for predicting water quality changes.
