北方农村小型次氯酸钠消毒水厂运行效果研究

Study on the operation effect of small sodium hypochlorite disinfection water works in northern rural areas

K水厂是北方小型集中式供水工程的典型代表,供水人口2000人,水源类型为地下水,水源水质好。为了给水源水质较好的北方农村小型集中式供水工程的建设模式提供依据,本文采用仪器分析等方法,开展了水处理工艺的选择、水质化学分析以及水厂运行成本计算等研究。研究表明,在水源水质达标条件下,水厂净水工艺宜选择次氯酸钠消毒技术。水厂运行3个月过程中,次氯酸钠发生器运行稳定,出厂水及末梢水水质稳定并能达标。水厂用电及药品的成本为0.51元/t。

K water treatment works were the typical representatives of small centralized water supply project in northern rural areas, the water supply has a population of 2000, groundwater type, and the water quality was good. In order to provide a basis for the construction o{ a small centralized water supply project in northern rural areas. The instrument analysis method was adopted and the selection of water treatment process, chemical analysis of water quality, waterworks operation cost calculation were researched. The results showed that under the condition of the water quality can reach the standard, water treatment works should choose sodium hypochlorite disinfection technology. In 3 months of operation process, sodium hypochlorite generator running stability, the finished water and tap water quality is stable and can reach the relevant standards. The cost of electricity and drugs for water works was 0. 51yuan/t.
