摘　　要：对南方某自来水厂水量约为4000 m^3/d的滤池反冲洗废水进行回用,根据前期烧杯试验数据,结合实际生产运行情况,综合分析了回用该部分生产废水后各工艺段出水和出厂水水质的变化。结果表明,直接回用滤池反冲洗水不会对出厂水水质造成负面影响,而且具有改善混凝效果、节约水资源和减少废水排放的多重意义。The filter backwashing wastewater with a capacity of about 4000 m3/d was reused in a waterworks in south China.According to the data of perious beaker test and considering the actual production and operation situation,the water quality changes of the effluent from each process section and the final effluent water after the reuse of this part of the production wastewater were comprehensively analyzed.The results showed that the direct reuse of filter backwashing water would not have a negative impact on the quality of effluent,but also had multiple meanings of improving coagulation effect,saving water resources and reducing wastewater discharge.
