摘要
给水厂生产尾水包括沉淀池排泥水和滤池反冲洗水,回用生产尾水对水资源的保护具有重要意义。通过分析生产尾水的水质特点,探讨了生产尾水直接回用、膜过滤、投加PAM化学药剂等几种处理技术,并对这几种技术的优缺点进行了分析和比较,得出从饮用水安全角度考虑,膜技术在给水厂生产尾水的回收利用方面会逐渐成为首选技术。
The reuse of tail water in water supply plants,including settling tank sludge water and filter backwash water,is of great significance to the protection of water resources.The reuse technologies such as direct reuse,membrane filtration and chemical treatment are discussed through the analysis of the features of tail water.From the perspective of the safety of drinking water,by analyzing the advantages and disadvantages of the above technologies,it is believed that membrane filtration will gradually become the primary technology for recycling tail water in water supply plants.
