摘　　要：在生产性规模为110万m^3/d的南方A水厂,研究了给水厂滤池反冲洗水直接回用对后续工艺段出水的水质影响。长期运行数据表明,直接回用滤池反冲洗水不会对后续工艺段出水的浊度、有机物、重金属、微生物和水生无脊椎动物造成负面影响。其长期运行处理效果稳定,能有效减少废水排放且节约水资源,是给水厂进行节能改造的一种可行方式。In a water treatment plant with a capacity of 1.1 million m^3/d in southern China,the influence of direct reuse of the filter backwashing water on the water quality of the subsequent process sections was studied.Long-term operational data indicated that direct reuse of the filter backwashing water would not adversely affect the water quality of the subsequent process sections in terms of turbidity,organic matter,heavy metals,microbes and aquatic invertebrates.Without undermining the stable purification performance of the plant in long-term operation,direct reuse of filter backwashing effectively reduced wastewater discharge and saved water resources.Therefore,this is a viable way of energy conservation for water treatment plants.
