摘要
收集东北地区16座净水厂自用水消耗的资料,分析了水厂絮凝池、沉淀池等的排泥工况对水厂自用水耗水率及排泥水含固率的影响,以及水厂滤池反冲洗工况对自用水耗水率和反冲洗效果的影响。基于数据分析,对东北地区典型水厂自用水耗水率现状进行综合评价。调查结果表明,东北地区的水厂耗水率受水源水质、处理规模、处理工艺(新建或改造)和运行管理等条件的影响,自用水的节约潜力在于优化运行参数以适应季节变化和水量负荷的变化,以及改造滤池反冲洗方式。
Based on the collection of self water consumption of 16 water treatment plants in the Northeast China, this paper studied the impacts of sludge discharge operation of flocculation tank, sedimentation tank on water treatment plants self water consumption rate and sludge drainage solid content, and the impacts of back-washing operation of filter tank on self water consumption and back-washing effects. Based on data analysis, the current self water consumption rate of typical water treatment plant in the Northeast China was evaluated comprehensively. The results showed: self water consumption rate of water treatment plant in the Northeast China is affected by water resource water quality, water production scale, treating process (newly constructed or upgraded), and operation and management, and so on; water-saving potential in self water consumption lies in operation parameter optimization, so which could adopt to the change of seasons and water production load, and the upgrade of filter tank back-washing.
