摘要
当供水水源发生高浓度藻（水华）时，水厂的滤池极易被藻堵塞，水处理不能继续运行，对此应从速采取水源除藻的应急措施。每天一次向含藻水体水中投加0．5～1mg／LCuSO4，连续投加2-3d后，除藻有效且能使水厂水处理工艺正常运行。投加高锰酸钾0．5-2mg／L或加入游离性余氯0．2～1mg／L，亦可有效除藻。
When water supply source has large concentrations of algae （algal bloom）, the filters of water works are clogged very easily and water treatment operation can not work normally. Excessive algae in water source should be removed immediately in case of emergency. If 0.5-1 mg/L CuS04 once a day for two to three days is used, algae can be effectively removed. Then water works can operate normally. 0.5-2 mg/L potassium permanganate or free 0.2-1 mg/L chlorine residual can be also effectively to remove algae.
