复合生物修复技术治理山西汾河水华污染水体的研究

Using composite bioremediation technology to clean water bodies of Fen River being polluted by algal bloom

选用3种复合生物制剂对山西汾河公园景区水体进行了治理与修复,研究了技术运用过程中藻类的生长和种属变化、水体透明度的改善,以及水生态系统的恢复。结果显示,治理后藻细胞密度明显低于治理前,有效抑制了蓝藻的生长,且有害蓝藻出现频率较低,水华得到有效控制,水体水质和透明度得到改善,水体生态环境得到修复。

Three types of compound biological agents are employed for cleaning and recovery of water bodies of Fenhe Garden in Shanxi Province. Research are made on growth and changes of alga species during the application of the technology and cleaning of water bodies and recovery of ecosystem. The result indicates that the density of alga matrix can be reduced with the technology which effectively control the algal bloom and reduce the frequency of its occurrence. As a result, water quality has been improved and eco-environment of the water body was restored.
