草履虫──针杆藻群落对混合印染废水净化作用的条件实验

The Condition Experiment that Paramecium-Acerate Algae Community Purificated the Printing and Dyeing Wastewater

本文对混合印染废水的静态净化过程，进行了生物群落观察和条件实验。发现废水净化初期以大量细菌和草履虫（以 Ｐ． Ｃａｕｄａｔｕｍ为主）繁殖为特征，同时伴生着少量浮游藻类。随着净化过程的进行，细菌和草履虫数量下降，以针杆藻（以 Ｓ． ａｕｃｓ为主）为建群种的浮游藻类群落占优势。化学分析表明，净化作用与温度、光照条件及废水起始浓度有关。

The observing of the ecology community and the condition experience experiment are protected to the puritication process of mixed printing and dyeing wastewater. It is discovered that many bacteria and paramecium are reproduced in the early wastewater purification, and concomitancely produced a few swimming algae. In the course of purification process,the less quantity the bacteria and the paramecium, the more the swimming algae. The chemical analysis indicate, the purification is connected with the tempe...
