典型自来水厂制水能力挖潜评估研究与实践

南方某水厂设计产水规模为15×10^4m^3/d,因用地条件所限,已不具备原地扩建可能,为应对逐年增长的城市用水需求,对该水厂制水能力进行了深入评估,挖掘现有水处理构筑物潜力,充分利用设计冗余,并结合实际实施局部改造,达到水量提升的目标。实践证明,该厂产水量可以提高至18×10^4m^3/d,改造后水质稳定达标。根据该案例总结出一套针对常规工艺水厂的产能评估与挖潜的方法,为缓解自来水供需矛盾提供了新的思路。

Research and Practice on Renovation and Evaluation of the Water Production Capacity in a Typical Waterworks

Due to land use limits, it' s impossible for a waterworks with production capacity of 15×10^4 m^3/d in southern China to expand onsite. In order to cope with the growing urban water demand , the water production capacity of the waterworks was evaluated in depth to explore the potential of the water treatment structures, make full use of the redundancy of design , reconstruct the structures combined with the actual condition, and achieve the goal of increasing water treatment capacity. The practice result showed that the water production capacity of the plant could increase to 18×10^4 m^3/d with stable effluent quality after the reformation. According to the case, a set of evaluation and innovation methods for increasing production capacity of traditional processes were summarized, which could provide a new way to alleviate the contradiction between water supply and demand.
