由于江河水源保护区重新划定,部分未划入保护区的水厂拟实施关停。为及时弥补因关停水厂造成的供水能力缺口,通过从技术经济等方面比选方案,最终决定重新修复和启用邻近水厂原已停运的旧制水系统。通过与邻近水厂给水主干管网的多点连通,实现区域间水量的实时调配,确保关停片区用水高峰期供水安全稳定。以某水厂为例,就旧制水系统复产的现状背景、方案比选、具体措施、注意事项等进行分析,供业内参考。 Due to the redrawing of the river water source protection area, some water plants not included in the reserve will be closed for implementation. In order to make up for the shortage of water supply capacity caused by the closure of waterworks in a timely manner, it finally decided to re-repair and re-establish the old water system that had been out of operation in the neighboring waterworks through technical and economical comparison. Through the multi-point connection with the main water supply network of the adjacent waterworks, real-time water allocation between regions can be realized and the water supply in the shut-off area can be ensured to be safe and stable. Taking a water plant as an example, this paper analyzes the current situation, program comparison, concrete measures and precautions of the rehabilitation of the old water system for the reference of the industry.
