- Development Status of the Combined Ultraviolet Disinfection Technology in Drinking Water
- Keywords:
- drinking water; microbial risk; UV; multi-barrier disinfection
- 摘要:
- 简述了国内外饮用水紫外线组合消毒技术的研究成果与应用发展历程，通过实地调研发现国内多数水厂在运行半年至两年后紫外设备停用的现状，并分析其停用的原因。通过三个典型案例分析讨论了紫外线组合消毒技术的运行参数，结果表明紫外线组合消毒工艺对微生物灭活效果更好，使用的化学药剂剂量更少，消毒副产物的风险降低，更能提升饮用水的口感，保障饮用水的健康，是未来饮用水消毒技术发展的趋势之一。
- Abstract:
- The domestic and foreign research results and application development history of the combined ultraviolet(UV) disinfection technology for drinking water are briefly described. Through field investigations, the status of UV equipment deactivation is found in most domestic waterworks after half a year to two years of operation. The operation parameters of the combined UV disinfection technology are discussed and analyzed through three typical cases, and the conclusions are as follows: the combined UV disinfection process has a better effect on inactivating microorganisms, uses fewer doses of chemicals, which effectively reduces the risk of disinfection by-products, improves the taste of drinking water, protects the health of drinking water. In summary, the combined UV disinfection technology has become one of the development trends of drinking water disinfection technology in the future.
