集中式饮水除砷装置的研制

A pilot study on arsenic removal facilities for central supply of drinking water

为验证本专题研制的强化除砷剂的除砷效果、除砷容量以及再生效果 ,必须有中试规模的试验装置及其运行状况 ,以便推进饮水除砷剂及其除砷技术的产业化进程 ,中试基地选在源水含砷量超标的浙江省某天然泉水饮料厂 ,该集中式饮水除砷装置的处理能力为 1m3 h ,自 1999年 4月起连续运行至今 ,处理后出水符合国家生活饮用水有关卫生标准的要求 ,除砷容量高 ;成本低 ,设备管理简单 ,进水和出水均无需调节pH ;再生剂安全、价廉、效果好 。

In order to promote the application and industrialization of an arsenic removal agent developed in this project, and to improve the technology, it is necessary to have a median sized facility to test the effects, capacity and regeneration of the agent. A facility with the capacity of 1 m 3/h for arsenic removal was installed in a bottled water plant, which has been operated since April 1999. The results showed that the arsenic content of effluent water has met the requirement of the national standard for drinking water. The effect of arsenic removal was by 2 mg/g. The annual cost per person was only 1 46 Yuan RMB. The operation and maintenance of the facility was simple and no need to adjust the pH of influents and effluents. The chemical regenerative agent was safe, low cost and effective. Therefore, the facility can be used in rural areas and the water plants while the arsenic in source water was higher than 0 05 mg/L.
