Abstract:

Aiming the character of floodwater, the process of coagulation-activated carbon-ultrafiltration for the treatment of floodwater has been studied. The result shows that the combined process is effective and stable. The removal of organisms is effective, and the average removal efficiency of COD_Mn, UV ₂₅₄are 75% and 71% respectively. There are not any turbidity and bacteria in the effluent water. Its quality reaches the national sanitary standard for drinking water.

Key words: coagulation, ultrafiltration, floodwater, granular activated carbon

摘要：

针对洪水的水质特征,研究了混凝、活性炭和超滤膜对洪水中浊度、有机物和细菌等主要污染物的去除效果,确定了混凝—活性炭—超滤组合处理工艺。试验结果表明,该组合工艺稳定、可靠。运行期间对浊度、有机物去除效果较好,对COD_Mn的去除率为75%,对UV₂₅₄的去除率为71%,系统出水中未检出大肠杆菌,浊度基本被完全去除,主要水质指标达到国家饮用水卫生标准。
