摘要
通过自行设计的水生植物系统对污水的净化处理,研究了自1990年8月至1991年4月共8个月污水处理过程中,系统内藻类种类、数量及叶绿素 a 含量变化.研究结果表明。系统中共鉴定到藻类40个属,始终以小球藻为优势种,藻类数量和叶绿素 a 含量在系统中呈现有规律的变化.同时,藻类的特征在一定程度上指示了系统设计的合理性及对污水处理的效果较高.
The research on algae kinds identifying,the total cell numbers of algae,chlorophylla concentrations,and their changes in aquatic plant system,from September 1990 to April 1991,is re- ported.The results show that there are 40 genera of algae.Chlorella is dominant,the total cell number of algae and chlorophyll a concentrations present regular changes.In addition,algal characteristics re- veal the rational design of the system and high wastewater treatment efficiencies to a certain extnt.
