摘要
在反应器中装满填料并接种鞘丝藻和颤藻，经培养驯化后填料上生长藻类膜。藻类膜能大大提高藻类的浓度，其处理效果优于普通 的悬浮藻系统。藻类利用污水中的氮源和磷源来合成细胞物质，3d 时间对氨氯的去除率可以达到81． 5%，对磷酸盐的去除率可以达到94． 4%，同时使出水中溶解氧含量明显提高，水质大大改善。藻类在填料上挂膜容易，易于脱落以保持活性，并易于和水分离。
The reactor loaded with plastic padding which were covered with Lyngbya and Oseillatoria amoena Com. biofilm. After cultured, the algae biofilm grows on the pacted - bed. The alga biofilm can raise the concentration of the algae and its treatment result is superior to the ordinary suspended algae system. Algae makes use of the nitrogen source and the phosphorus source in the wastewater to synthesis cell materials. The removal rate of ammoniaoal nitrogen can reach 81.5%, while phosphate can reach 94.4% after three days＇ treatment. It obviously raise the dissolved oxygen and the quality of water of the effluent at the same time. The algae biofilm is prone to stick and slough so as to keep its activation. It is also easy to be separated from the wastewater.
